(Santa Barbara, Calif.) UC Santa Barbara chemistry professor Bruce Lipshutz has been awarded the 2012 Encyclopedia of Reagents for Organic Synthesis (EROS) Best Reagent Award. The annual award is sponsored by Sigma-Aldrich and John Wiley.

"It's a terrific acknowledgement of the students who did the work; this is really their award," said Lipshutz. With his lab team, Lipshutz developed copper hydride-based reagents that can be used in very small amounts, and are capable of several types of reactions potentially useful for the synthesis of various materials from drugs to polymers, to naturally occurring molecules.

Aside from being very reactive, said Lipshutz, the catalysts called (R)-()-DTBM-SEGPHOS copper hydride; and (S)-(+)-DTBM-SEGPHOS-copper hydride are versatile, inexpensive, and produce high yields of the desired products.

"We want to push the envelope as to how low a level of these reagents can be utilized yet still be effective with this kind of chemistry, especially when being done in water rather than in organic solvents," said Lipshutz, who will be giving the award lecture at Wayne State University in the fall.

Lipshutz and his lab are part of an emerging movement called "Green Chemistry," a field that emphasizes environmentally benign processes. These involve reduced energy requirements, the use of less hazardous and more environmentally friendly chemicals, and the reduction of waste. In 2011, Lipshutz won the Presidential Green Chemistry Challenge Award, given to a single academic in this case, for the development of an enabling technology that allows these types of metal-catalyzed reactions to be conducted in water, and at room temperature. The more traditional approach typically involves using organic solvents and energy in the form of applied heat. Lipshutz's technology also has the added benefit of being "benign by design;" based on innocuous vitamin E, it results in virtually no pollution. In water it forms nanoparticles that serve as nanoreactors wherein the catalytic reactions take place.

Specially-engineered surfactants make synthetic chemistry processes efficient by eliminating side-product formation that typically results from heating, Lipshutz said. They also reduce the need for both purification and the disposal of potentially hazardous waste, and usually result in a reduction in costs associated with those processes. Catalysts substances that facilitate or generate reactions without themselves being consumed or changed by the process are particularly favored because they are used in small amounts and can oftentimes be recycled.

"In addition to the upfront costs, re-purification and/or disposal of organic solvents can be expensive," said Lipshutz, who estimates that pharmaceutical companies produce roughly 50-200 kilograms of waste for every kilogram of drug. "Why not get the best of all worlds why not benefit from their spectacular products that are so essential for maintenance of human health, and yet, not create such enormous organic waste, over 70 percent of which is organic solvent," he said. "Organic chemists are paying serious attention to this issue, which is a natural outgrowth of the industry. We as a community worldwide have certainly contributed to these environmental problems, but we can surely help to solve them as well; and that is exactly what we at UCSB plan to do."

The odds on a takeover bid materialising for Yule Catto shortened considerably when shares of the chemicals maker crashed 38.9p, or 22 per cent, to a 52-week low of 138p on a shock profits warning.

Investors bailed out after the company said it expects business to be hit by the volatile euro and by weak demand for nitrile in Asia, a region where it was increasingly shifting its focus.

Nitrile is a speciality chemical used in the manufacturing of latex a very fine quality of rubber used in the making of rubber gloves. Yule Catto had said in March that it expected sales from emerging markets to offset low growth in developed markets but now the board reckons demand will remain weak until next year.

Speciality chemical companies have in recent years been swallowed like flies.

International bidders have swooped on those companies that make anything from additives for everyday products, such as paints, to materials used in the semiconductor industry. The diversity of their businesses makes the sector recession proof, as the need for their chemicals will always be there.

Yule Catto last year was the subject of intense speculation that either Dow Chemical or BASF of Germany was prepared to fork out 1.2bn or 350p a share in cash to swallow the Harlow-based company.

Any interested party would have to get the green light from Kuala Lumpur Kepong, which owns 19 per cent of Yule Cattos equity and has been a major shareholder since 1976.

Following overnight strength in Asian markets amid speculation that another rate cut by China is just around the corner, growing optimism that Europes leaders could yet deliver a positive surprise at today and tomorrows EU summit in Brussels helped the Footsie climb 76.96 points to 5,523.92 and the FTSE 250 86.6 points to 10,751.98.

Robert Grubbs, recipient of the 2005 Nobel Prize for chemistry, talks with visitors at the Science Museum of Western Virginia. Grubbs was in Southwest Virginia for the World Polymer Congress at Virginia Tech in Blacksburg.

As a "green" chemist, Robert Grubbs works to counter the image of scientific endeavors as spreading pollution and risk.

The California scientist said during a visit to Roanoke he's finding ways to turn plant products into fuel and insect pheromones into pesticide replacements.

If Grubbs says that's possible, it probably is. He was awarded the 2005 Nobel Prize for chemistry, an honor given for his work in catalysts.

"Once you've got a catalyst, you can do all kinds of interesting stuff," Grubbs told an audience of 25 Tuesday at the Science Museum of Western Virginia. He was in Southwest Virginia for the World Polymer Congress at Virginia Tech in Blacksburg.

Grubbs, 70, a professor at the California Institute of Technology in Pasadena, Calif., ran through a series of scientific slides and personal photos during an informal, hour-long talk brought about by the science museum's partnership with Tech. There is a shot of him receiving the Nobel Prize from the king of Sweden. There is a shot of his sons, one a chemist and one a doctor, and his daughter, a psychologist for military veterans.

The psychic wounds of war, he said, are "worse than you think."

Grubbs is a native of Kentucky who holds bachelor's and master's degrees from the University of Florida and a doctorate in chemistry from Columbia University. He taught at Michigan State University from 1969 to 1978, when he joined Caltech.

Among a career with many highlights, he split $1.2 million with two others when named a Nobel Prize winner, he said. Asked before his talk about the impact on his life, he quoted his wife: "We dance more and we drink better wine."

WASHINGTON, June 27, 2012 The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes the first-of-its-kind "pyroelectric nanogenerator," a new device designed to harvest the enormous amounts of energy wasted as heat every year to produce electricity.

Based on a report by Zhong Lin Wang, Ph.D., and colleagues in the ACS journal Nano Letters, the new podcast is available without charge at iTunes and from http://www.acs.org/globalchallenges.

In the report, Wang and colleagues explain that more than 50 percent of the energy generated in the U.S. every year goes to waste, much of it as heat released to the environment by everything from computers to cars to long-distance electric transmission lines. Heat can be converted to electricity using something called the pyroelectric effect, first described by the Greek philosopher Theophrastus in 314 B.C., when he noticed that the gemstone tourmaline produced static electricity and attracted bits of straw when heated. Heating and cooling rearrange the molecular structure of certain materials, including tourmaline, and create an imbalance of electrons that generates an electric current. Wang's group wanted to apply the ancient principle to make a nanogenerator (NG), which uses a time-dependent temperature change to generate electricity and could take advantage of heat changes in the modern world.

To do that, the researchers made nanowires out of zinc oxide, a compound added to paints, plastics, electronics and even food. Using an array of short lengths of nanowire standing on end, they demonstrated a device that produces electricity when heated or cooled. They suggest the NGs could even produce power as temperatures fluctuate from day to night. "This new type of NG can be the basis for self-powered nanotechnology that harvests thermal energy from the time-dependent temperature fluctuation in our environment for applications such as wireless sensors, temperature imaging, medical diagnostics and personal microelectronics," the researchers said.
