China’s shipbuilder AVIC Weihai Shipyard has held a keel-laying ceremony for a new RoPax vessel being built for Swedish ferry company Stena Line.The traditional maritime event, which took place on February 2, 2018, marks the start of the construction phase of the hull and the exterior parts of the vessel.“This is an important milestone in our exciting new ship building project,” Niclas Mårtensson, CEO Stena Line, said.Stena Line’s new RoPax vessels will be deployed on the Irish Sea. The new vessels, which will be 50% bigger than today’s standard RoPax units, have a planned delivery timetable during 2019 and 2020.“Our overall target is that these vessels will be the absolute state-of-the-art when it comes to energy efficiency, flexibility and customer service. In particular, we are placing heavy emphasis on developing a range of exciting new digital features which will provide our customers with unique additional services connected with their journey as well as developing a new, integrated digital onboard experience,” Mårtensson added.Featuring a length of 214.5 meters and a breadth of 27.8 meters, the new ships are capable of carrying 1,000 passengers.Image Courtesy: Stena Line
zoomIllustration; Source: Pexels under CC0 Creative Commons license Denmark’s port of Esbjerg is to expand its eastern port area as it plans to construct a new, 40,000-m2 multi-terminal in response to increased demand.The new terminal is expected to be completed by the end of the year, the port said, adding that it can see increasing demand for areas with access to quays and cranes.The new multi-terminal would be set up west of the existing multi-terminals in the eastern port. It would have direct access to the three ramps already established at the quay, the port informed.“We can see increased demand for sites for the storage and shipping-out of cargo, cars and, containers, as well as components for the wind turbine industry. The new terminal is intended to meet that demand, giving our customers the best possible conditions for running and developing their business,” Dennis Jul Pedersen, Port Director at Port Esbjerg, said.The costs of establishing the terminal are expected to run to a total investment of around DKK 15 million (USD 2.26 million).An invitation to tender for the construction of the new terminal will be announced during the new few weeks.The terminal is expected to be completed in November 2019 and will be located adjacent to the two existing multi-terminals at the port, which are operated by Blue Water Shipping and Scandinavian Auto Logistics.In 2018, Port Esbjerg handled 4.4 million tonnes of cargo, as a hub for RoRo traffic, with six fixed liner services and connections to more than 25 ports.
Murray Coolican, deputy minister of both the Business and Energy departments will retire at the end of the month, Premier Stephen McNeil announced today, Dec. 4. Mr. Coolican became deputy minister of Energy in 2010 after holding leadership positions in the non-profit, government, political and private sectors. He was appointed deputy minister of Business in 2016, in addition to the Energy portfolio. “Murray has contributed to the growth of our province as a civil servant, as a business leader and as a volunteer. He has worked with business, industry and post-secondary education on policy and innovation, to the benefit of all Nova Scotians,” said Premier McNeil. “I am particularly grateful for his leadership in ensuring Nova Scotia remains a leader in Canada in combatting climate change.” Mr. Coolican served as senior vice-president at Maritime Life and vice-president at a number of companies including Nova Scotia Power, Corporate Communications Limited and National Sea Products. He also held senior positions with the Government of Ontario and served as special assistant to former premier and federal Opposition leader Robert Stanfield. The process to replace Mr. Coolican will begin immediately.
Rabat – The Moroccan government has announced that it will not renew its IMF Precautionary and Liquidity Line (PLL). The deal, signed in 2011, will end in July 2018.According to the IMF, the PLL “provides financing to meet actual or potential balance of payment needs of countries with sound policies, and is intended to…help resolve crises under wide-ranging situations.”Morocco appealed to IMF’s financial and structural support in 2011, when, in the feverish and uncertain political situation marked by the Arab Spring, the country sought to maintain investor trust , particularly that of FDI (Foreign Direct Investment). From PLL to the Flexibility LineAccording to La Tribune Afrique, Morocco, feels confident enough to decline IMF’s offer to extend the PLL deal, in part due to the new exchange rate initiated by regime on January 15. It should be noted that although Morocco contracted the USD 3.47 billion included in the PLL in 2011, renewing it twice in order to readily face any eventual economic crisis or market shock, the government reports that it actually never used the allowance. On Sunday, 21 January, IMF Managing Director Christine Lagarde arrived in Morocco, where she was due to chair a conference on IMF economic policies in the MENA region. Lagarde, it was reported, came to Morocco hoping to address alleged frustrations brought on by IMF policies in the region andfind common ground with MENA government representatives. The two-day conference was titled “Opportunities for All: Growth, Employment and Inclusion in the Arab World,” with the aim of assessing IMF policyand deriving new pathways for MENA growth.Speaking to the press on the sidelines of the Marrakech conference, Moroccan Finance Minister Mohamed Boussaid explained that the efficiency and the effectiveness with which the country’s current exchange rate regime is implemented are such that the liquidity and precautionary line is no longer needed.“There is no need to renew it [PLL]. The macroeconomic situation and the present indicators are satisfactory,” Boussaid said, adding, however, that “this does not mean that our good relationship with the IMF should not continue.”For his part, the governor of Morocco’s Central Bank reiterated the government’s stance on the PLL, underlining that Morocco’s economy is now moving toward a more “flexible line” for “stronger economies,” rather than the “liquidity line” intended for economies in crisis or transition. He added that Morocco’s objective is to maintain eligibility for the IMF’s Flexible Credit Line (FCL), conceived for countries with strong policy frameworks and well-performing economies; this credit line was designed for crisis mitigation or prevention.As for the IMF delegates, they saluted Morocco’s handling of the PLL. They also praised Morocco’s current exchange rate regime. Jihad Azour, the IMF director for the MENA region, reported, “It is a reform that is doing well. It allows Morocco to attract investors and fully play its financial role in the MENA region.”
Rabat – After the support of the Arab League, Romania, and Gulf Cooperation Council, Djibouti has voiced its “full” solidarity and “total” backing of Morocco’s decision to cut diplomatic ties with Iran due to its interference in Morocco’s internal affairs.Djibouti’s Minister of Foreign Affairs and International Cooperation and spokesman of the government Mahmoud Ali Youssouf sent a letter today to his Moroccan counterpart, Nasser Bourita, to emphasize Djibouti’s support for Morocco’s decision to cut ties with Iran.Commenting on the Moroccan move, Youssouf reaffirmed his country’s support “for all measures taken by your country to guarantee its security and stability and to face any attempt to undermine its territorial integrity and the safety of its citizens.” On May 1, the Moroccan Ministry of Foreign Affairs announced the diplomatic break, confirming the presence of “tangible evidence” of Iran’s involvement in delivering military equipment to the Polisario and training its militias.In response to the Moroccan statement, Djibouti’s official denounced Iranian interference, stressing the importance of respect for the principles governing relations between states, especially “respect for national sovereignty and non-interference in the internal affairs of other countries.”The decision to cut ties with Iran followed the adoption of the United Nations Security Council resolution 2414, which urges Polisario to withdraw from the Guerguerat buffer zone and to stop their illegal operations in Western Sahara. The country’s announcement represents further evidence of Polisario’s involvement in illegal actions, which have deemed destabilizing for the region as a whole.Polisario and Iran have denied their connection, while Algeria has attempted to distance itself from the regional conflict over Western Sahara.On Wednesday, Algeria summoned Morocco’s ambassador to Algiers and condemned Bourita’s comments accusing Hezbollah of providing military training and weapons to the separatist group through Algeria.Reacting to Algeria’s action, the Moroccan Ministry of Foreign Affairs denounced the Algerian declaration, reframing the public condemnation in terms of Algerian embarrassment over the repeated instances documenting Algeria-Polisario collusion.
The killing of three protesters in Rathupaswala in 2013 during a protest over drinking water has been ruled as a crime.The ruling was given by the Gampaha Magistrate today.
Under-Secretary-General Jan Egeland was able to visit Mutambala Bridge, which used to be the front line between the Rassemblement Congolais pour la Democratie (RCD-Goma) and Mayi-Mayi militia during prolonged fighting. A water and sanitation supervisor and 10 water committee workers were abducted and killed in the area earlier this year.At the bridge, the two sides promised full freedom of movement for the civilian population and said they were pleased with their reconciliation.The DRC’s eastern region is the location of the world’s worst humanitarian crisis, with 3.5 million people having been displaced and thousands of girls and women having suffered torture and violation.The visit to Baraka is part of Mr. Egeland’s broader goals of increasing the humanitarian access to and presence in previously difficult to reach areas of the Great Lakes region, OCHA said.He was scheduled to go to Goma, a town of 400,000, later today and to Bunia in Ituri district tomorrow.
“Low food prices reduce the incomes of farmers, especially poor family farmers who produce staple food in the developing countries. This cut in the flow of cash into rural communities also reduces the incentives for new investments in production, infrastructure and services,” said José Graziano da Silva, the Director-General of the UN Food and Agriculture Organization (FAO), at a high-level meeting on agricultural commodity prices in Rome. The Director-General noted that globally, food prices are believed to be back to their long-term downward trend in real terms, as supply growth outpaces demand. This follows the price surges experienced during 2008-2012, and a prolonged period of volatility in food markets. He underscored the need to consider the current decline in agricultural commodity prices in the context of the international community’s efforts to achieve the 2030 Agenda and the Sustainable Development Goals (SDGs). In a video address to the meeting, World Trade Organization (WTO) Director-General Roberto Azevêdo said that under the right circumstances, trade provides people with opportunities to join global markets and helps to create incentives for producers to invest and innovate. The “historic decision” struck in Nairobi in December 2015 by WTO members to eliminate agricultural export subsidies will “help level the playing field in agriculture markets, to the benefit of farmers and exporters in developing and least-developed countries,” according to Mr. Azevêdo. Wide view of the opening session of the fourth Ministerial Meeting on long-term commodity price trends and sustainable agricultural development, at FAO headquarters Plenary hall, Rome. Photo: FAO/Giulio Napolitano For his part, Mr. Graziano da Silva pointed to the potential of trade in contributing to global food security and better nutrition, specifically underlining its potential role as an “adaptation tool” to climate change – countries that are projected to experience decreasing yields and production due to climate change will have to resort to the global markets to feed their populations. But the Director-General also noted that increased openness to trade can also bring risks. If not well managed, it “can undermine local production and consequently the livelihoods of the rural poor,” he said. The elimination of agricultural export subsidies that affect prices in global markets could be one way to improve trade so that it benefits small farmers in developing countries and creates prosperity in rural areas, he added. With demand representing one of the most powerful drivers of food prices, an essential way to make these more remunerative for producers, yet affordable for consumers, is to promote and strengthen targeted social protection programmes and other schemes such as food vouchers, the FAO Director-General said. “The aim of these policies is to build a virtuous cycle of local production and local consumption,” said Mr. Graziano da Silva. To succeed, such measures need strong collaboration between the institutions responsible for agriculture, rural development, trade, the environment, nutrition, health and social security, he noted. To better develop future scenarios on the long-term behaviour of agricultural commodity prices, he highlighted that FAO seeks to boost its modelling systems to better understand possible price swings and changes in trends and assist countries to formulate appropriate policies. The OECD-FAO Agricultural Outlook, a joint publication of FAO and the Organisation for Economic Co-operation and Development (OECD), points out the high probability that over the next 10 years, some abrupt price surges may occur, mainly as a result of climate change.
Members of Melbourne’s Hellenic clubs gathered in a meeting organised by the Pan Macedonian Association of Melbourne and Victoria in Clifton Hill last Thursday evening to decide the Greek Community’s next actions regarding the ‘Macedonia’ name dispute. In the meeting, the community representatives discusses the suggested names for FYROM by UN mediator Matthew Nimetz, the relations with Greece’s Balkan neighbours, and the ongoing conversation between Athens and Skopje.Mr Nimetz said on 1 February that he was “optimistic Balkan neighbors ‘Macedonia’ and Greece could resolve a name dispute that has strained relations between the two countries for more than a quarter of a century”.After talks with FYROM:s leadership in Skopje, Nimetz told reporters that officials in both countries appear highly motivated to reach a solution over the name within the next couple of months, with the new FYROM name most likely being a modifier to the word ‘Macedonia’ by adding ‘Upper’, ‘New’, or ‘North’ to it.More than 250 community members attended the meeting in a tense atmosphere which led to several verbal conflicts and embarrassing incidents with some members calling themselves ‘more patriot’ than others. Several fanatics booed Professor Christos Fifis, one of the community’s key supporters. Mr Fifis is known for devoting his life to Greece, the Greek Australian community, and Hellenic studies. He was not allowed to share his opinion when he asked to speak, and he was forced to withdraw by those who disagreed.One of the attendees demanding the diaspora’s support verbally offended all of the elderly members of the community calling them “old”.The climate was divisive, as members that had attended the previous FYROM name rally in Melbourne ended up quarrelling with the Pan Macedonian Association’s president Peter Iassonides who called their protest “faceless”. By the end of the meeting, however, most representatives agreed that the protest was welcomed by the community. President of the Greek Community of Melbourne and Victoria, Bill Papastergiadis, also asked everyone to support this year’s Lonsdale Street Festival as it will also have a “Macedonian colour”, promising to give a call-out to all Greek Australians asking them to attend the 4 March rally.

Peter Turnquest gave details in the House of Assembly of the Government’s recent success at issuing a benchmark US$750 million bond issue, which has been opened to the markets and priced, and is expected to close on November 21, 2017. He made the statement on Wednesday, November 15, 2017.DPM Turnquest also took the time to set the record straight in response to numerous reports in the Press and social media about the transaction, which characterised it as “lacking in transparency and fiscal prudence.”“Nothing could be further from the truth. There was absolutely nothing devious, surreptitious or imprudent about this transaction or the manner in which it was handled. There are certain ways these transactions are handled in the international market, and we are appropriately guided by our investors in this regard,” he told the Members of Parliament.DPM Turnquest explained that all of the Government’s financing activities are conducted within the constraints of its approved borrowing authorities, and shaped and informed by pragmatic debt management strategies.“These strategies, for example, take into consideration the size and currency composition of the Government’s financing requirements; the identification, analysis and preferences of potential funding sources—whether it is best to source the debt in domestic or foreign currency; and, of course, with due consideration to market liquidity, cost and risk factors.“To be sure, such analysis and evaluation requires interaction with other agencies—especially our bankers, and most certainly the Central Bank. As is customary, we collaborate very closely with the Central Bank, which manages the issuance of government paper in the domestic market, for advice on domestic liquidity conditions—how much excess loanable funds are in the system, and what is the appetite of the main investors in government paper—the banks and institutional investors (pension funds and the insurance companies) to increasing their holdings.”He said these factors, including foreign reserves considerations, not only influence the timing and size of potential issues, but also determine decisions on whether borrowings are undertaken in domestic or foreign currency. Such decisions involve serious and considered deliberations by the Government in managing the country’s debt. The DPM noted that during the 2017/18 Budget Communication, two borrowing resolutions were approved by the House.The first covered the additional funding approval of $400 million to settle the outstanding arrears for FY2016/17 and the second was in respect of FY2017/18, and provided for financing to cover the overall budget deficit, estimated at $322.3 million, and refinancing/debt repayment obligations, which are now projected at $600.2 million.He said, “Therefore, while the total borrowing envelope under these two approved resolutions totaled approximately $1,322.7 million, the increment to the outstanding debt was and remains $722.3 million, as the $600.2 million in refinancing/debt repayment would have a neutral impact on debt levels.”DPM Turnquest also noted that it is instructive to mention, that, at the beginning of each Fiscal Year, one of the first things that the Government sets out to do, through its Treasury Department, is to develop monthly cash flow projections—based on how it perceives the evolution of revenue performance and the timing of its outlays.“These projections are calibrated, on an ongoing basis, to ensure that there are sufficient funds available to meet the Government’s budgetary requirements, as and when needed.“It is now common knowledge that there were pressing funding needs at the end of the past fiscal year and the outset of the current period, which placed an urgent requirement on policymakers to identify immediate funding sources to meet these obligations.”He said after an evaluation of the funding options, the Government moved expeditiously to source several short-term bridging facilities, which included US Dollar bank credits ($450 million) and domestic treasury bills and bank advances ($300 million).“I want to emphasize that these facilities were always contemplated to be short-term in nature, with a subsequent “terming out”, i.e., lengthening of the maturities to achieve a more favourable debt servicing profile. And having considered conditions in the domestic market, and the number of significant rollovers contemplated, the intention was to explore the possibility of rolling up these short-term credits into an international bond issue.”The bonds, characterized as a 10-Year weighted average life bond, was priced at a coupon or interest rate of 6.00 per cent, which is some 250 basis points above the pricing obtained in the Government’s last bond issuance in 2014 when it enjoyed investment grade credit status.It is to be repaid in three equal annual installments, commencing on November 21, 2026, and with a final maturity on November 21, 2028. T he 6.00 per cent yield is equivalent to a spread of 362.1 basis points above the US Treasury’s 10-year benchmark bond.The Deutsche Bank Securities Inc. and RBC Capital Markets, LLC. managed the offer as joint book runners.By: Llonella Gilbert (BIS) Facebook Twitter Google+LinkedInPinterestWhatsApp
SEATTLE — Veteran Republican U.S. Rep. Doc Hastings, who represented central Washington for two decades and was a key voice in public lands and energy policy, announced Thursday he’ll retire at the end of the year. As chairman of the House Natural Resources Committee, Hastings recently took on the Endangered Species Act, calling for an overhaul of the law to curtail environmentalist lawsuits and give more power to states. Hastings and other GOP critics contend the 40-year-old law has been abused by environmental groups seeking to restrict development in the name of species protection.“The biggest problem is that the Endangered Species Act is not recovering species,” Hastings said at a news conference last week where 13 GOP lawmakers proposed “targeted reforms” for the law that protects imperiled plants and animals.“The way the act was written, there is more of an effort to list (species as endangered or threatened) than to delist” them after declaring they are no longer threatened, Hastings said.Born in Spokane, the Pasco-based lawmaker was first elected to the U.S. House in 1994 after beating then-congressman Jay Inslee, the current Washington governor. Before his career in the nation’s capital, Hastings served in the state House from 1979 to 1987.
Hearst’s House Beautiful is taking to the small screen this year—the publication is launching a partnership with HSN, formerly known as the Home Shopping Network, to raise awareness about the brand and foster commerce and consumer interaction.“This partnership represents the future, moving commerce in a modern direction,” says Newell Turner, the publication’s editor-in-chief. “It’s an opportunity to marry our brand’s editorial authority with retail. House Beautiful has a distinct point of view that our readers love. HSN has deep expertise in creating and sourcing product for retail. Now together we are enabling consumers to access great taste and design in a whole new way. We have readers at every stage of life and income, and HSN is making it possible for all of us to have a more beautiful home.” Turner defines the House Beautiful Marketplace as a place consumers can visit to shop for furniture, lighting, rugs, decorative accessories and art for their homes. The House Beautiful Marketplace will debut on HSN TV and Turner himself will be appearing in episodes and online to offer his take on the latest trends in home design. The website for the marketplace (HSN.com/HouseBeautiful, pictured right) gives Web visitors information on House Beautiful picks, and expert decorating advice from editors and writers.“There is going to be some cross-promotion between HSN and House Beautiful, but in the end it’s really all about shopping for things to make your home more beautiful and a reflection of your personal style,” says Turner. “I’m now involved with all the media platforms, so when I’m going to be a guest on an HSN show, I’ll definitely be tweeting that I’m on air. Think of it as taking the magazine to TV. We’re going to be part of HSN’s broadcast design week three times a year. I or one of my editors will be the guest of shows devoted to home design. We’ll be there to talk about what we see happening in the world of interior design. Online at HSN.com, some of our shopping columns will be extended with more home furnishings available through HSN.”Going forward, some monthly columns in the magazine will include products seen on the House Beautiful Marketplace program. Turner says the partnership can be looked at as a content source for the magazine on different furnishing offerings and services. The editorial will remain largely independent, though there will be some intersections between editorial content and television programming. HSN approached the publication about this collaborative effort, though Turner declined to comment on whether or not this represented a paid partnership.“Our partnership came out of our desire to reach the consumer wherever she is—on her mobile device, on her computer, watching television—and offer her ease of access to great style for her home, beyond the pages of the magazine,” says Turner. “We were interested in what they were doing—making great design available to everyone.”
.The United States warned Friday that it was losing patience and again threatened to quit the UN Human Rights Council after the Geneva-based body adopted five resolutions condemning Israel.US ambassador Nikki Haley said in a statement that the council was “grossly biased against Israel,” noting that it had adopted only three resolutions separately targeting North Korea, Iran and Syria.”When the Human Rights Council treats Israel worse than North Korea, Iran, and Syria, it is the council itself that is foolish and unworthy of its name,” said Haley.”Our patience is not unlimited. Today’s actions make clear that the organization lacks the credibility needed to be a true advocate for human rights,” she said.Haley has over the past year repeatedly warned that the United States was ready to walk away from the 47-member body established in 2006 to promote and protect human rights worldwide.The five resolutions were presented by the countries of the Organisation of Islamic Cooperation under the council’s “agenda item 7” which concerns Israel.Israel is the only country that has a dedicated agenda item at the council, a mechanism that the United States and some European countries view as inappropriate.The latest threat to quit the council came after President Donald Trump appointed UN-skeptic John Bolton as his national security adviser.Since Trump took over at the White House, the United States has quit the UN cultural agency UNESCO, cut UN funding and announced plans to quit the UN-backed Paris climate agreement.
Scientists Working Toward Better Batteries Citation: New Hitachi Li-ion batteries to last ten years (2010, April 9) retrieved 18 August 2019 from https://phys.org/news/2010-04-hitachi-li-ion-batteries-ten-years.html (PhysOrg.com) — Hitachi has announced they may be able to double the life of rechargeable lithium-ion (Li-ion) batteries through the development of a new cathode material. The material was developed in conjunction with the company Shin-Kobe Electric Machinery, and while it will not be useful initially for small applications such as laptops, cameras or smartphones, it may be ideal for larger batteries in hybrid or electric vehicles, and for storing excess energy produced by wind farm generators. © 2010 PhysOrg.com More information: Original Hitachi paper (Japanese): www.hitachi.co.jp/New/cnews/mo … h/2010/04/0405a.html Explore further The new battery uses more manganese for the positive electrode and reduces the use of the far more expensive cobalt. Hitachi says the new cathode material is the composite oxide lithium manganese spinel (LIMn2O4), a crystalline material that is much more stable than the previous cathode material. Its stability makes the cathode more resistant to attack by the electrolyte, and inhibits leaching of cathode material into the electrolyte (both processes that eventually stop the battery holding a charge). The new cathode material extends the life of the battery to ten years from the more usual average working life of five years, and it also boosts the battery’s capacity. The battery will also be cheaper than current lithium-ion batteries because of the reduced use of cobalt.Lead-acid batteries are usually used for large installations because of their longer working life of up to 10 years, and also because of their lower cost. Lithium-ion batteries have about quadruple the power density of the lead-acid batteries, so if their lifetime could be doubled and the cost reduced, they could replace the traditional batteries for the larger applications.Lithium-ion batteries are found in almost all portable electronic devices these days, and the new battery technology may be able to be scaled down for use in these gadgets. The battery is at prototype stage at the moment, but Hitachi expects it to be available for larger scale industrial uses probably early in 2011.The new battery was produced with the aid of Japan’s New Energy and Industrial Technology Development Organization, and Hitachi hopes its concentration on batteries for ecologically sustainable industries such as wind farms and electric vehicles will help it return to profitability.

The new OLET, which is 10 times more efficient than any other reported OLET, has a trilayer structure. Electrons from the green layer and holes from the blue layer move to the middle red layer, where excitons are formed and light is emitted. Image copyright: Nature Publishing Group. (PhysOrg.com) — Already, organic light-emitting diodes (OLEDs) are becoming commercialized for light display applications due to their advantages such as low fabrication costs and large-area emission. But OLEDs also have intrinsic efficiency limitations due to their structure, which might limit their future development in terms of brightness. Now, a team of researchers has found that another organic semiconductor-based device, the organic light-emitting transistor (OLET), can dramatically increase the efficiency of OLEDs since OLETs have the structure of a transistor rather than a diode. In their recent study, the researchers have created OLETs that are 10 times more efficient than any previously reported OLET, as well as more than twice as efficient as an optimized OLED made with the same materials. More information: Raffaella Capelli, et al. “Organic light-emitting transistors with an efficiency that outperforms the equivalent light-emitting diodes.” Nature Materials. Doi:10.1038/NMAT2751 The researchers, Raffaella Capelli, et al., from the Institute for Nanostructured Materials (ISMN) in Bologna, Italy, and the Polyera Corporation in Skokie, Illinois, USA, have published their results in a recent issue of Nature Materials.As the researchers explain, OLED technology is by far the most developed of the two organic semiconductor-based devices. But the biggest drawback to using OLEDs for light display applications is that they intrinsically suffer from photon loss and exciton quenching. Both effects are a direct result of the structure of OLEDs: The close spatial proximity of the electrical contacts and the light-generation region causes some emitted photons to be absorbed, resulting in photon loss. Similarly, the largest quenching effect in OLEDs, called exciton-charge quenching, reduces the number of excitons, and occurs due to a spatial overlap of excitons and charges. Because OLETs have a transistor-based structure, researchers have recently been looking for ways to suppress these deleterious effects inherent in the OLED architecture. So far, they have only managed to prevent one type of quenching called exciton-metal quenching, which was done by moving the light-emitting area further away from the electrodes. However, the other effects still remained, so that the best OLETs only achieved an efficiency of no more than 0.6%.In the new study, the researchers designed an OLET that could avoid photon losses and the two types of quenching. In demonstrations, the new OLETs achieved efficiencies of 5%. In comparison, equivalent OLEDs had efficiencies of just 0.01%, while optimized OLEDs with the same emitting layer as the OLETs achieved efficiencies of 2.2%, with the difference being due to their diode structure. (Although 2.2% is the highest reported efficiency for OLEDs based on fluorescent emitters, researchers have recently reported OLEDs based on phosphorescent emitting material with an efficiency on the order of 20%.) Citation: New OLETs emit light more efficiently than equivalent OLEDs (2010, May 31) retrieved 18 August 2019 from https://phys.org/news/2010-05-olets-emit-efficiently-equivalent-oleds.html Explore further Copyright 2010 PhysOrg.com. All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. The researchers call their novel device a tri-layer field-effect OLET due to its three organic semiconducting layers: a top 15-nm-thick p-channel layer that transports holes, a 40-nm-thick middle layer that emits light (the “exciton formation zone”), and a bottom 7-nm-thick n-channel layer that transports electrons. In this set-up, electrons and holes move from their respective layers to the middle layer, where excitons are formed and light is emitted. The three semiconductor layers are positioned on a three-layer substrate of glass, indium tin oxide, and PMMA, and two gold electrodes on top complete the design.The trilayer architecture offers several advantages. For one, the light-formation and light-emitting regions are located far enough away from the electrodes so that photon losses at the electrodes and exciton-metal quenching are prevented. Also, the light-emitting region is physically separated from the charge flows, which prevents exciton-charge quenching. For these reasons, the researchers describe the tri-layer OLET as a “contactless OLED,” where these deleterious effects are intrinsically prevented. In addition to these improvements, the researchers predict that the efficiency of the new OLET should be able to be increased even further with further adjustments, such as decreasing the operating voltage and carefully tuning every part of the structure.“Despite the necessary technical improvements, we believe that our tri-layer OLETs represent a viable route to increase even further the device efficiency,” Capelli, a researcher at ISMN, told PhysOrg.com.Overall, the scientists hope that the OLET represents a route toward developing practical organic light-emitting devices with unprecedented efficiency. The device could offer the potential for many applications, such as intense nanoscale light sources and optoelectronic systems.“The OLET is a new light emission concept, providing planar light sources that can be easily integrated in substrates of different natures (silicon, glass, plastic, paper, etc.) using standard microelectronic techniques,” said Michele Muccini, a researcher at ISMN. “Our devices provide planar micrometer-size light sources that might enable organic photonic applications like integrated on-chip bio-sensing and high resolution display technology with embedded electronics. Moreover, a long term perspective for OLETs could be related to the realization of an electrically pumped organic laser.” Liquid-OLED Offers More Light-Emitting Possibilities This document is subject to copyright.

If you are an employee who perceives you are overqualified for your position, chances are you are unsatisfied with your job, uncommitted to your organisation and experience psychological strain, says a study. Perceived overqualification occurs when an employee is expecting a job that utilises their qualifications but does not find themselves in such a position, leaving them feeling essentially deprived.”We invest effort at work and we expect rewards in return, such as esteem and career opportunities,” said Michael Harari, Assistant Professor at Florida Atlantic University in the US. Also Read – Add new books to your shelf”And for an overqualified employee, that expectation has been violated. This is a stressful experience for employees, which leads to poor psychological wellbeing, such as negative emotions and psychological strain,” Harari added.Perceived overqualification – the belief that one has surplus skills compared to job requirements – can have negative implications for employees and employers alike, according to the findings published in the Journal of Vocational Behavior.

Dynamic EdgeT Gating Technology, by Calypso Medical Technologies, is designed to protect healthy tissue from unintended radiation.The technology will be on display at the American Society for Radiation Oncology (ASTRO) conference in San Diego, Calif.It allows therapists to set motion thresholds which disable radiation delivery if the targeted tissue moves outside the preset threshold. Previously, the therapist had to manually intervene when healthy tissue was in danger of receiving unintended radiation. Dynamic Edge Gating provides an immediate response so the radiation beam is automatically disabled or re-enabled in response to organ motion. As a result, it may help decrease the side effects associated with prostate radiotherapy, such as bowel and bladder incontinence and sexual dysfunction. The Calypso System, with its GPS for the Body technology, utilizes miniature implanted Beacon transponders to provide precise, continuous information on the location of the tumor during external beam radiation therapy.
