IR spectroscopy of H(MeOH)n+ clusters in the liquid phase: evidence for a proton wire
Date: May 5, 2008
Author:
The long-standing problem of understanding the nature of the excess proton in acidified water is simplified by studying the proton in methanol by IR spectroscopy. The data indicate that a chain of up to four O-H-O bonds can act as an electrical wire to separate positive charge.

Fancy ants for arthritis
Date: May 1, 2008
Author: David Bradley
Ants are perhaps not the first organism one would turn to for medical assistance, but researchers in Hong Kong and Japan have now used IR and NMR spectroscopy to study the absolute structures of compounds extracted from Chinese medicinal ants that are thought to have anti-arthritic activity and be beneficial in treating hepatitis.

A novel ATR-FTIR method for functionalised surface characterisation
Date: Apr 6, 2008
Author:
A novel method for analysing ex situ-prepared chips by ATR-FTIR circumvents tedious functionalisation steps of internal reflection elements and simultaneously allows for complementary measurements by other analytical techniques.

The highs and lows of ozone
Date: Apr 1, 2008
Author: David Bradley
Chemistry that takes place way above our heads is not just less accessible than you might imagine but has more significance than was first thought for those of us with our feet firmly on the ground.

FTIR analysis of the conformational quality of recombinant proteins within inclusion bodies
Date: Mar 3, 2008
Author:
The use of FTIR spectroscopy for the structural analysis of inclusion bodies purified from cells and in vivo is reviewed, with examples concerning aggregation kinetics and structure as a function of expression levels, temperature and co-expression of chaperones.

Spot the difference
Date: Mar 1, 2008
Author: David Bradley
While there is scant evidence for the efficacy of aromatherapy in treating disease, it is well known that certain fragrances, such as mint, lavender, and jasmine, can influence stress-induced psychosomatic disorders. Now, a near infrared spectroscopic study of the brain and facial skin secretion response to long-term use of a specific fragrance could provide useful clues about the underyling neurophysiological mechanism of such changes.

On-line near IR of glycerol-boosted anaerobic digestion processes
Date: Feb 4, 2008
Author:
A study of NIR as a tool for process monitoring of thermophilic anaerobic digestion boosted by glycerol has been carried out, aimed at developing simple and robust process analytical technology modalities for on-line surveillance in full scale biogas plants.
