Water molecules continuously form short-lived clusters that can be rapidly protonated in the liquid state. Now, computer simulations revealed how protonated water clusters interact with nearby messenger molecules, which are required to measure their geometrical structures and the chemical properties by IR spectroscopy.

Heating rice flour to 600 Celsius under a nitrogen atmosphere is not the usual way to cook it, but researchers in India have done just that. The product, rather than a bowl of light and fluffy grains is a plethora of nanoscopic carbon cubes and bricks, the team says [June 1, 2010] |

Scientists have reported the discovery of what may be the "ancestral Eve" crystal that billions of years ago gave life on Earth its curious and exclusive preference for so-called left-handed amino acids. Fourier transform IR spectroscopy and powder X-ray diffraction provide the evidence. [May 1, 2010] |

A portable IR device that can quickly and easily determine the strength of alcoholic drinks proves more effective than laboratory-based FTIR spectroscopy. The device could be useful in law enforcement and in industry fraud. [April 1, 2010] |
|
Infrared radiation was used to increase the curing rate of linseed and tung oils and FTIR spectroscopy was used to monitor the chemical changes during oil oxidation. [April 1, 2010] |
|
Organisms use ATP as a universal energy storage molecule, now carbon nanotubes, modified with luciferase, have been used as near-infrared detectors for cellular ATP. The work has potential for studies of ischaemia, Parkinson's disease, hypoglycaemia and more. [March 1, 2010] |
|
A fast, versatile, inexpensive and environmentally safe analytical method was developed to quantify simple sugars, malic acid and total phenolic compounds in apple pomace, considering its potential use as a raw material with value instead of as an industrial waste. [March 1, 2010] |
|
Anomalies in the spectra of the aromatic planar molecule coronene can be explained with powerful calculations on infrared and Raman spectroscopic data. The evidence suggests that minute out-of-plane molecular distortions from D(6h) to C(2h) symmetry are the underlying cause. [February 1, 2010] |
|
This study describes near infrared spectroscopy to examine platelets inoculated with low concentrations of Bacillus cereus and Staphylococcus epidermidis, comparing with sterile bags. [February 1, 2010] |
|
An improved detection method was described for reverse-phase protein arrays combining near-infrared fluorescence with one or two rounds of tyramide-based signal amplification. [January 4, 2010] |
|
It won't necessarily be music to the classical purist's ear, but chemists have been instrumental in revealing the secret beneath the varnish on a Stradivari violins, and the secret is: there is no secret. [January 1, 2010] |
|
The appropriateness of near-infrared reflectance spectroscopy for the estimation of stable isotope ratios for nitrogen and carbon of plant tissues has been demonstrated on seven bog species from Patagonia. [December 2, 2009] |
|
Microwave waveguides on a diamond-based chip can generate a magnetic field large enough to change the quantum state of an atomic-scale defect in less than one billionth of a second, emulating the process involved in magnetic resonance imaging and potentially leading to a new approach to quantum computing. [December 1, 2009] |

The board of directors of Thermo Fisher Scientific Inc. has appointed Marc N. Casper president, chief executive officer and a director of the company, effective 15 October 2009. Casper currently serves as executive vice president and chief operating officer. This announcement follows the decision of Marijn E. Dekkers to resign as president, chief executive officer and a member of the board, in order to become chief executive officer of Bayer AG. [November 3, 2009] |
