Synthetic rubber and plastics – used for manufacturing tires, toys and myriad other products – are produced from butadiene, a molecule traditionally made from petroleum or natural gas. But those manmade materials could get a lot greener soon, thanks to the ingenuity of a team of scientists from three U.S. research universities. The scientific team –- from the University of Delaware, the University of Minnesota and the University of Massachusetts – has invented a process to make butadiene from renewable sources like trees, grasses and corn. The findings, now online, will be published in the American Chemical Society’s ACS Sustainable Chemistry and Engineering, a leading journal in green chemistry and engineering. The study’s authors are all affiliated with the Catalysis Center for Energy Innovation (CCEI) based at the University of Delaware. CCEI is an Energy Frontier Research Center funded by the U.S. Department of Energy. “Our team combined a catalyst we recently discovered with new and exciting chemistry to find the first high-yield, low-cost method of manufacturing butadiene,” says CCEI Director Dionisios Vlachos, the Allan and Myra Ferguson Professor of Chemical and Biomolecular Engineering at UD and a co-author of the study. “This research could transform the multi-billion-dollar plastics and rubber industries.” Butadiene is the chief chemical component in a broad range of materials found throughout society. When this four-carbon molecule undergoes a chemical reaction to form long chains called polymers, styrene-butadiene rubber (SBR) is formed, which is used to make abrasive-resistant automobile tires. When blended to make nitrile butadiene rubber (NBR), it becomes the key component in hoses, seals and the rubber gloves ubiquitous to medical settings. In the world of plastics, butadiene is the chief chemical component in acrylonitrile-butadiene-styrene (ABS), a hard plastic that can be molded into rigid shapes. Tough ABS plastic is used to make video game consoles, automotive parts, sporting goods, medical devices and interlocking plastic toy bricks, among other products. The past 10 years have seen a shift toward an academic research focus on renewable chemicals and butadiene, in particular, due to its importance in commercial products, Vlachos says. “Our team’s success came from our philosophy that connects research in novel catalytic materials with a new approach to the chemistry,” says Vlachos. “This is a great example where the research team was greater than the sum of its parts.” Novel chemistry in three steps The novel chemistry included a three-step process starting from biomass-derived sugars. Using technology developed within CCEI, the team converted sugars to a ring compound called furfural. In the second step, the team further processed furfural to another ring compound called tetrahydrofuran (THF). It was in the third step that the team found the breakthrough chemical manufacturing technology. Using a new catalyst called “phosphorous all-silica zeolite,” developed within the center, the team was able to convert THF to butadiene with high yield (greater than 95 percent). The team called this new, selective reaction “dehydra-decyclization” to represent its capability for simultaneously removing water and opening ring compounds at once. “We discovered that phosphorus-based catalysts supported by silica and zeolites exhibit high selectivity for manufacturing chemicals like butadiene,” says Prof. Wei Fan of the University of Massachusetts Amherst. “When comparing their capability for controlling certain industrial chemistry uses with that of other catalysts, the phosphorous materials appear truly unique and nicely complement the set of catalysts we have been developing at CCEI.” The invention of renewable rubber is part of CCEI’s larger mission. Initiated in 2009, CCEI has focused on transformational catalytic technology to produce renewable chemicals and biofuels from natural biomass sources. “This newer technology significantly expands the slate of molecules we can make from lignocellulose,” says Prof. Paul Dauenhauer of the University of Minnesota, who is co-director of CCEI and a co-author of the study. Additional co-authors include Prof. Michael Tsapatsis, postdoctoral researchers Dae Sung Park, Charles Spanjers, Limin Ren and Omar Abdelrahman, and graduate student Katherine Vinter, all from the University of Minnesota, and graduate student Hong Je Cho from the University of Massachusetts.

DUBLIN--(BUSINESS WIRE)--Research and Markets has announced the addition of the "Global Rubber Gloves Market: Industry Analysis & Outlook (2017-2021)" report to their offering. Rubber gloves were invented primarily for medical staff to prevent them from developing dermatitis from chemicals. The market has thereafter seen significant use of rubber gloves in other segments as well with passing time. Increased healthcare infrastructure and mandated reforms has always kept the demand for rubber gloves high and would continue to do in the future as well. The rubber gloves market has come long way with increased innovation and product differentiation by the manufactures. Rubber gloves are broadly classified under nitrile rubber gloves and latex rubber gloves. Nitrile rubber gloves are slowly replacing the latex rubber gloves because of the allergies cause by latex proteins. A developed nation like that of the US has mandated the use of nitrile gloves, leading to its increased demand. Whereas, in case of the emerging economies the demand for latex gloves has been high because its cost is very low and is cheaply available. Malaysia is the largest exporter of rubber gloves in the world because of its dynamics and better operating efficiencies led by encouraging government policies. The global rubber gloves market growth will be driven by up-gradation of manufacturing efficiencies, and increased penetration in the developing nations. The major trends of the market include shift from natural rubber gloves to NBR gloves, capacity expansion, and increased demand for powder free latex gloves. However, the market will be hindered by volatility in prices of raw materials, hike in natural gas tariff, speculation and high dependence on foreign labor.

Three new personal protective products from Detectamet are made from a material that offers the food industry valuable benefits. It reduces food contamination risks by being metal and X-ray detectable and incorporates anti-bacterial benefits. The apron and sleeve covers are tough enough for a repeated use of at least 3 months. York, United Kingdom, May 24, 2017 --( This reduces their environmental impact and increases their value for money. The aprons, full length sleeve covers and three-quarter smocks are ideal for use in the meat, fish and dairy processing industries where work areas are subject to high water usage and soiling. The Polyester material with its NBR-rubber coating results in a waterproof, robust and durable material that is permanently flexible and washable. This material is practical in high or very low temperatures down to -65 °C (-85°F ) and can be machine washed at up to 90 °C (194°F). Even under this vigorous regime these robust products have demonstrated their durability by lasting for an average of 3 months in regular use. They also resist animal oils and fats, and can cope with strong detergents and acids and alkaline liquids making them well suited for use in a challenging food production environment. The standard colors are blue or white although the covers can be ordered from a range of special colors subject to minimum order quantities. They measure 90cm (36”) wide and are supplied either 135cm (54”) or 155cm (61”) in length. The dual detectable Sleeve Covers are approximately 18” (45 cm) long but subject to minimum order quantities longer sleeve covers can be produced. The elasticated wrist and shoulders give a firm but comfortable fit, and like the aprons these covers can be regularly cleaned at temperatures up to 90 °C (194°F) to maintain a high level of hygiene. The aprons, three-quarter smocks and the sleeve covers are highly durable so they can be re-used time and again without compromising hygiene levels. As a consequence these tough, dual detectable, antibacterial and practical products are very cost effective. For more information contact jon.Ireland at detectamet.com.

This article originally appeared on the Motley Fool. After two weeks of fairly steady gains, crude oil lost a step this week. After gaining 11% from May 9-May 23, Brent crude futures have fallen 4%, from over $54 to $52 at the close on May 26. The big driver this week has been relatively mixed news. OPEC announced it would continue its plan to cut output by 1.8 million barrels per day, keeping production at recent levels in an effort to stabilize prices. Unfortunately, this good news wasn't particularly well received by the market. Some were hoping the cartel would even consider a bigger cut, as U.S. crude production has continued to climb in recent months. According to Baker Hughes, the U.S. active rig count has increased every week for almost five months, steadily pushing domestic oil output higher and cancelling out a significant portion of OPEC's production cuts. In short, this renewed uncertainty around global oil supplies has taken the wind out of the oil rally -- at least for now. According to  S&P Global Market Intelligence, some of the biggest losers this week were independent oil and gas producer  Bill Barrett Corporation (NYSE:BBG), and oilfield service companies  Nabors Industries Ltd. (NYSE:NBR), Pioneer Energy Services Corp (NYSE:PES), and Fairmount Santrol Holdings Inc (NYSE:FMSA): While Bill Barrett is a small, independent oil and gas producer, Pioneer Energy Services, Fairmount Santrol, and Nabors Industries are oilfield service providers. Pioneer Energy and Nabors Industries are drilling contractors, while  Fairmount Santrol generates more than 70% of its business from making and selling proppants used in oil and gas production. • This Stock Could Be Like Buying Amazon in 1997 In a weak oil-price environment, it's often these kinds of companies -- ones that work for the oil producers -- who are the first to feel the pinch of falling oil prices as producers look to cut costs. Oil prices are likely to remain volatile for the foreseeable future. And while OPEC's decision to extend production cuts is relatively positive for oil prices, the market put more value in the news that North American shale production would probably grow faster than anticipated this year, stopping the recent mini-rally and sending prices lower. At the same time, beyond the connection between falling oil prices and the risk that producers cut back on drilling activity, there's no material news that Pioneer Energy, Fairmount Santrol, or Nabors Industries are facing any new challenges. Even with oil prices falling a little this week, many U.S. producers can still make money at current crude prices. At the end of the day, it seems unlikely that U.S. shale production will bridge the gap between OPEC's continued cuts and global consumption. If that proves to be the case, this week's market reaction may have been a little premature. However it plays out, there's still a lot of oil in the market that needs to be worked through before there's any chance oil prices can push past $60 per barrel. • 7 of 8 People Are Clueless About This Trillion-Dollar Market Until that glut is worked through, crude prices will probably go through these weekly swings, dragging oil and gas stocks along for the ride.

Rating scales, such as Likert scales, are very common in marketing research, customer satisfaction studies, psychometrics, opinion surveys, population studies, and numerous other fields. We recommend diverging stacked bar charts as the primary graphical display technique for Likert and related scales. We also show other applications where diverging stacked bar charts are useful. Many examples of plots of Likert scales are given. We discuss the perceptual and programming issues in constructing these graphs. We present two implementations for diverging stacked bar charts. Most examples in this paper were drawn with the likert function included in the HH package in R. We also have a dashboard in Tableau.
