STAR PREVIEW John Deere Classic Preview with BLUE HORSESHOE

first_imgWe’re back to a familiar venue this week on the PGA Tour with a return to Deere Run in Illinois, where the event has been played since 2000. The 7,268 yard, Par 71, Deere Run course has a reputation as a low scoring venue with winning scores in excess of twenty under par being carded in four of the last five years. With past winners such as Brian Harman, Zach Johnson, Ryan Moore, Jordan Spieth and Michael Kim, it’s clear that prodigious length off the tee’s is not a prerequisite to do well here.An amazing statistic is that we’ve had TEN first time winners on the PGA Tour this season. Players like Matt Wolff are coming to the PGA Tour ready to win and are not overawed by the occasion, or the opportunity to grab their maiden PGA tour win if it presents itself. While this makes picking winners even harder than usual, it’s great for the sport. The game of golf is in rude health at present. Long may it continue because it will make for excellent events and nail-biting finishes.Blue Horseshoe Loves:Brian Harman – currently at 25/1 with starsports.betHarman played very well last week at the 3M Open to finish tied for seventh on sixteen under par. His straight driving game and excellent putting game are big assets around Deere Run and he knows how to win here, having been victorious in 2014.Sam Burns – Currently at 45/1 with starsports.betSam Burns must have heard about my threats to disown him last week, if he didn’t pull his socks up and play to the potential he clearly has. He finished alongside Harman on a tie for seventh on sixteen under par. His final round of seven under sixty-four was the low round of the day and he will take a great deal of belief from his very solid showing. I am going with Burns again. He is not far away in my eyes.Danny Lee – Currently at 75/1 with starsports.betAfter a string of good performances and high finishes over the last month or so, Danny Lee was disappointing last week. But I’m prepared to cut him a break and give him another chance at a gentle venue that should suit his game very well.Talor Gooch – Currently at 66/1 with starsports.betGooch is another playing that has been knocking on the door this season. After watching a raft of his fellow debutants get wins this year, Gooch must also be thinking that he can take the next step from credible showings to actually winning one of these tournaments. His putting and driving games have been consistent and he represents great each way value at an undemanding venue such as this.RECOMMENDED BETS (scale of 1-100 points)BACK BRIAN HARMAN 1.5pt each way 25/1 with starsports.betBACK SAM BURNS 1pt each way 45/1 with starsports.betBACK DANNY LEE 1pt each way 75/1 with starsports.betBACK TALOR GOOCH 1pt each way 66/1 with starsports.betew 6 places 1/5 oddsPROFIT/LOSS SINCE JAN 1 2017: PROFIT 164.73 points(excluding Cricket World Cup ante-post, England v Australia)last_img read more

Scalable CVD process for making 2D molybdenum diselenide

Credit: E. Ringe/Rice UniversityThe method for making two-dimensional molybdenum diselenide uses a technique known as chemical vapor deposition (CVD) and is described online in a new paper in the American Chemical Society journal ACS Nano. The finding is significant because CVD is widely used by the semiconductor and materials industries to make thin films of silicon, carbon fibers and other materials.“This new method will allow us to exploit the properties of molybdenum diselenide in a number of applications,” said study leader Pulickel Ajayan, chair of Rice’s Department of Materials Science and NanoEngineering. “Unlike graphene, which can now easily be made in large sheets, many interesting 2-D materials remain difficult to synthesize. Now that we have a stable, efficient way to produce 2-D molybdenum diselenide, we are planning to expand this robust procedure to other 2-D materials.”In the Rice study, Ajayan and colleagues tested their atomically thin layers of molybdenum diselenide by building a field effect transistor (FET), a commonly used device in the microelectronic industry. Tests of the FET found the electronic properties of the molybdenum diselenide layers were significantly better than those of molybdenum disulfide; the latter is a similar material that has been more extensively studied because it was easier to fabricate. For example, the FET tests found that the electron mobility of Rice’s molybdenum diselenide was higher than that of CVD-grown, molybdenum disulfide.Pulickel AjayanIn solid-state physics, electron mobility refers to how quickly electrons pass through a metal or semiconductor in the presence of an electric field. Materials with high electron mobility are often preferred to reduce power consumption and heating in microelectronic devices.“Being able to make 2-D materials in a controlled fashion really will make an impact on our understanding and use of their fascinating properties,” said study co-author Emilie Ringe, assistant professor of materials science and nanoengineering and of chemistry at Rice. “Characterizing both the structure and function of a material, as we have done in this paper, is critical to such advances.”Molybdenum diselenide and molybdenum disulfide each belong to a class of materials known as transition metal dichalcogenides; TMDCs are so named because they consist of two elements, a transition metal like molybdenum or tungsten and a “chalcogen” like sulfur, selenium or tellurium.TMDCs have attracted intense interest from materials scientists because they have an atomic structure similar to graphene, the pure carbon wonder materials that attracted the 2010 Nobel Prize in physics. Graphene and similar materials are often referred to as two-dimensional because they are only one atom thick. Graphene has extraordinary electronic properties. For example, its electron mobility is tens of thousands of times greater than that of TMDCs.Emilie RingeHowever, two-dimensional TMDCs like molybdenum diselenide have attracted intense interest because their electronic properties are complementary to graphene. For example, pure graphene has no bandgap — a useful electronic property that engineers can exploit to make FETs that are easily switched on and off.As with many nanomaterials, scientists have found that the physical properties of TMDCs change markedly when the material has nanoscale properties. For example, a slab of molybdenum diselenide that is even a micron thick has an “indirect” bandgap while a two-dimensional sheet of molybdenum diselenide has a “direct” bandgap. The difference is important for electronics because direct-bandgap materials can be used to make switchable transistors and sensitive photodetectors.“One of the driving forces in Rice’s Department of Materials Science and NanoEngineering is the close collaborations that develop between the people who are focused on synthesis and those of us involved with characterization,” said Ringe, who joined Rice’s faculty in January. “We hope this will be the beginning of a series of new protocols to reliably synthesize a variety of 2-D materials.”The research was supported by the Army Research Office, the Semiconductor Research Corporation’s FAME Center, the Office of Naval Research and Singapore’s MOE Academic Research Fund.Additional study co-authors include Xingli Wang, Yongji Gong, Gang Shi, Kunttal Keyshar, Gonglan Ye, Robert Vajtai and Jun Lou, all of Rice, and Wai Leong Chow, Zheng Liu and Beng Kang Tay, all of Nanyang Technological University.-30-High-resolution IMAGES are available for download at:http://news.rice.edu/files/2014/04/0407_MOLY-mose2-lg.jpgCAPTION: This image from a scanning transmission electron microscope shows the individual atoms in a two-dimensional sheet of molybdenum diselenide.CREDIT: E.
