A green transformation for pharmaceuticals
Fri, 21 Nov 2014 12:11:41 EST
A more sustainable approach to a bond-forming reaction extensively used in the pharmaceutical and fine chemical industries has now been developed. The team used the solvent-free, catalytic reaction to produce high yields of a wide range of amides, including the antidepressant moclobemide and other drug-like molecules.

Streamlining thin film processing for electrodes, display screens
Fri, 21 Nov 2014 11:18:36 EST
Energy storage devices and computer screens may seem worlds apart, but they’re not. When an electrical engineering professor teamed up with and computer scientists to make a less expensive supercapacitor for storing renewable energy, they developed a new plasma technology that will streamline the production of display screens.

A new discovery about the atomic structure of uranium dioxide will help scientists select the best computational model to simulate severe nuclear reactor accidents.

Improved nanomaterials: Understanding surface structure of quantum dots will aid design of new solar devices
Thu, 20 Nov 2014 15:39:48 EST
A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has just emerged.

Quantum mechanical calculations reveal the hidden states of enzyme active sites
Thu, 20 Nov 2014 13:34:24 EST
Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as 'active' sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed. Now, researchers have reported the first direct observation of the electronic states of iron-sulfur clusters, common to many enzyme active sites.
