Quantitative elemental analysis of individual particles with the use of micro-beam X-ray fluorescence method and Monte Carlo simulation
Date: Nov 9, 2009
Author:
A Monte Carlo method was developed and combined with micro-beam X-ray fluorescence for the determination of the chemical composition of individual particles and was applied to a collection of glass micro-spheres,

17th century mathematics and 21st century materials
Date: Nov 1, 2009
Author: David Bradley
Nanoparticles can self-assemble into quasicrystalline structures, according to researchers in the USA. The newly discovery structures could provide useful insights into how such non-periodic, and yet ordered, that lie half way between amorphous solids and regular crystals can arise.

Analysis of intraindividual and intraspecific variation in semicircular canal dimensions using high-resolution x-ray computed tomography
Date: Oct 12, 2009
Author:
The intraspecific and intraindividual variations in the sizes of the three semicircular canals in the right and left temporal bones of the short-tailed shrew were measured on a high-resolution X-ray computed tomography system.

Soft X-ray spectromicroscopy of nickel sorption in a natural river biofilm
Date: Sep 14, 2009
Author:
Scanning transmission X-ray microscopy at the C 1s, O 1s, Ni 2p, Ca 2p, Mn 2p, Fe 2p, Mg 1s, Al 1s and Si 1s edges was used to study Ni sorption in a complex natural river biofilm.

Smokestack scrubber
Date: Sep 1, 2009
Author: David Bradley
Korean researchers have developed a new, highly porous material that can soak up carbon dioxide efficiently and highly selectively. The material, characterised by X-ray diffraction and other techniques might one day be used to "scrub" out the greenhouse gas from power stations and factories that burn fossil fuels for energy.

Chicken shack remediation
Date: Aug 15, 2009
Author: David Bradley
X-ray absorption spectroscopy and monitoring of soil enzyme activity have been used to monitor the effects on lead speciation of plant growth and added chicken guano. The approach could allow gun shooting clubs to clean up land contaminated with ammunition lead.
