Quasi on the inside: Rare earth crystals
Date: Jun 15, 2013
Author: David Bradley
Scientists at the Ames Laboratory in the USA have used an algorithm to fish for new rare-earth quasicrystals and have pulled out a new family of binary magnetic icosahedral quasicrystals containing several different rare earth elements and cadmium. The findings demonstrate that such materials have spin glass behaviour rather than magnetic behaviour.

Journal Highlight: Assessment of resin formulations and determination of the formaldehyde to urea molar ratio by near- and mid-infrared spectroscopy and multivariate data analysis
Date: Apr 15, 2013
Author: spectroscopyNOW
The molar ratios of formaldehyde to urea in resin formulations have been analyzed by ATR-FTIR and FT-NIR spectroscopy, using PCA to separate them according to molar ratios and to distinguish between two groups of resins, and SIMCA to classify new resin samples.
