  Graphene from dry ice Researchers at Northern Illinois University (NIU; DeKalb, Ill.; discovered a new method for producing graphene that involves burning pure magnesium metal in dry ice. The method, which is capable of producing large quantities of graphene in sheets less than ten atoms thick, is simpler than conventional methods for generating graphene, and avoids hazardous chemicals...

The research group of professor Akihiko Kondo at Kobe University (Kobe City, has developed a one-step, pretreatment process for making bioethanol from cellulose and lignocellulose. The process uses an ionic liquid — which converts cellulose into a gel — and a genetically engineered yeast (arming yeast) that...

A process for making polyols from soybean oil and glycerin has been licensed by its developer, Battelle (Columbus, Ohio;, to Emery Oleochemicals Americas (Cincinnati, Ohio;, who intends to produce the renewably sourced polyols at prices similar to those of petroleum-based polyols. As multifunctional alcohols, polyols are widely used in industry, especially for making...

A compact, inexpensive and energy-saving continuous process to make bioethanol is being developed by professor Yoshio Katakura at Kansai University (Osaka;, in collaboration with the Kinki Bio-industry Development Organization (Osaka), Kansai Chemical Engineering Co. (Amagasaki), and Akita National College of Industry (Akita, all Japan). The so-called CCSSF process...

Spider silk has many unique properties that make it suitable for applications such as coatings and medical products. As a protein, the silk is remarkably stable and is only destroyed physically or digested and recycled by the spider. However, an industrially viable synthetic route to spider silk has eluded researchers over the last 25 years, says Axel Leimer, managing director at AMSilk GmbH...

Last month, Brain AG (Zwingenberg; and Dechema e.V. (Frankfurt am Main, both Germany; began a collaboration in the biotechnological production of perillic acid — a patented natural monoterpene owned by Brain, with promising applications as a bioactive compound in cosmetics products and as a natural preservative. The cooperation is aimed at further developing an...

Hiroshi Abe and colleagues at Biochemical Group of Research Institute for Innovation in Sustainable Chemistry, National Institute of Advanced Industrial Science and Technology (Tsukuba, Japan; have discovered a strain of acetic-acid bacteria (which normally oxidize ethanol into acetic acid) that effectively converts highly concentrated (22%) glycerin into D-glyceric acid. The researchers...
