Protein engineers create new biocatalysts

Protein engineers at the California Institute of Technology (Caltech) have tapped into a hidden talent of one of nature's most versatile catalysts. The enzyme cytochrome P450 is nature's premier oxidation catalyst—a protein ...

Long-wavelength laser will be able to take medicine fingerprints

A laser capable of working in the terahertz range – that of long-wavelength light from the far infrared to 1 millimetre – enables the 'fingerprint' of, say, a drug to be examined better than can be done using chemical ...

Dreidel-like dislocations lead to remarkable properties

(Phys.org)—A new material structure predicted at Rice University offers the tantalizing possibility of a signal path smaller than the nanowires for advanced electronics now under development at Rice and elsewhere.

Diamond-like coating improves electron microscope images

(Phys.org)—Coating the surface of a material with a single layer of diamond-like crystals greatly improves images of it taken with an electron microscope, according to a study led by scientists at SLAC National Accelerator ...

In static friction, chemistry is key to stronger bonds

(Phys.org)—Inspired by phenomena common to both earthquakes and atomic force microscopy, University of Wisconsin–Madison materials engineers have learned that chemical reactions between two silicon dioxide surfaces cause ...
