Fuel matters: Insights into enzymatic conversion
Date: Jul 1, 2013
Author: David Bradley
Altering the crystalline structure of cellulose from its native form to another can lower its binding partition coefficient for fungal cellulose enzymes by 40-50 percent but surprisingly boost hydrolytic activity. This new finding could thus help open the road to more efficient enzymatic production of biofuels from biomass rather than petroleum.

What's the beef? Bovine antibodies X-rayed
Date: Jun 15, 2013
Author: David Bradley
US researchers have used X-ray diffraction to study several novel bovine antibodies that might one day lead to new types of agent against infectious pathogens.

Journal Highlight: Time-resolved X-ray PIV technique for diagnosing opaque biofluid flow with insufficient X-ray fluxes
Date: Jun 10, 2013
Author: spectroscopyNOW
X-ray particle image velocimetry in which an image intensifier was combined with a high-speed camera was used to reduce exposure time to below 200 µs, and applied to measure high-speed blood flows in a tube

Diffract and destroy: Fluctuation X-ray scattering
Date: Jun 1, 2013
Author: David Bradley
Fluctuation X-ray scattering could help fill the gaps in our knowledge of protein structure thanks to the short bursts of radiation allowing data to be obtained from non-crystallisable proteins in their native, fluid state albeit with the sacrifice of the protein itself.

Low-temperature feedstock: XRD and oxidation
Date: May 15, 2013
Author: David Bradley
X-ray diffraction has been used to study the low-temperature oxidation of the important feedstock chemical ethylene over platinum nanoparticles supported on mesoporous silica, according to a study published in Angewandte Chemie.

Journal Highlight: X-ray fluorescence analysis of Co, Ni, Pd, Ag, and Au in the scrapped printed-circuit-board ash
Date: May 7, 2013
Author: spectroscopyNOW
A validated method for the measurement of Co, Ni, Pd, Ag, and Au in ash derived from scrapped printed circuit boards used X-ray fluorescence spectrometry and gave similar results to those from atomic absorption spectrometry.
