Greenhouse scrubbers: Predicting adsorptive materials

Date: Aug 15, 2013

Author: David Bradley

Computational simulation and nuclear magnetic resonance (NMR) spectroscopy have been combined by chemists in the USA to help them predict accurately the adsorptive properties of highly porous synthetic materials known as crystalline multivariate-metal organic framework (MTV-MOF).

Colon cancer calculated: Metabolic profiling

Date: Aug 15, 2013

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy can be used to obtain a metabolic fingerprint of cancer of the bowel and so determine how far advanced the disease is, according to UK researchers.

Seeing clearly: X-rays help

Date: Aug 15, 2013

Author: David Bradley

The protein that maintains the clarity of the lens in the human eye has been analysed using X-ray crystallography and could provide new insights into how to treat potentially blinding cataracts and various other health conditions.

Magnetic switch: Terahertz controller

Date: Aug 15, 2013

Author: David Bradley

A terahertz laser developed at the Paul Scherrer Institute in Switzerland could be used to control the magnetization in a material on a timescale of just picoseconds. The extremely short pulses of electromagnetic radiation allow the magnetization to be changed with only a tiny delay opening up a new route to on-off switching in such materials for microelectronics and computing applications.

Journal Highlight: Refining the interpretation of near-infrared band shapes in a polyynediyl molecular wire

Date: Aug 5, 2013

Author: spectroscopyNOW

The near-IR spectrum of a ruthenium-diyne complex, which serves as a model for the linear carbon allotrope carbyne, has been reexamined to show that the presence of rotamers is a crucial variable that may influence the appearance of the intervalence charge transfer band and the underlying electronic structure.

Journal Highlight: The survival of gunshot residues in cremated bone: An inductively coupled plasma optical emission spectrometry study

Date: Aug 5, 2013

Author: spectroscopyNOW

ICP-OES analysis of gunshot residues in cremated bone is very sensitive and reliable and can be an appropriate nondestructive method for detecting residues on difficult and delicate substrates.
