New technology for simpler, more efficient production of “stubborn” metal and metal oxide thin films

Green Car Congress

“Stubborn” metals, however—which include elements such as platinum, iridium, ruthenium, and tungsten, among others—are very difficult to convert into thin films because they require extremely high temperatures (usually more than 2,000 degrees Celsius) to evaporate. —William Nunn, first author.

Researchers engineer E. coli for direct production of isobutyric acid

Green Car Congress

Researchers at the University of Minnesota led by Prof. Kechun Zhang have engineered a synthetic metabolic pathway using fungal and bacterial enzymes in E. Isobutyric acid also can be further converted to methacrylate (i.e., coli to enable the direct biosynthesis of isobutyric acid from glucose. Credit: Zhang et al.
