The short and the shorter of it: Infrared laser pulses

Date: Feb 1, 2015

Author:

A new technology that leads to self-shortening laser pulses could make short infrared pulses more accessible and cheaper, involving as it does sending an initial infrared laser pulse into a hollow fibre filled with gas.

NO says yes to MOF: Infrared spectroscopy, pores for thought

Date: Jan 8, 2015

Author: David Bradley

Infrared spectroscopy and other techniques have been used by researchers in France to show how the biologically important gas molecule nitric oxide, NO, can be trapped within porous materials known as metal-organic frameworks (MOFs).

Journal Highlight: Solvation dynamics of a single water molecule probed by infrared spectra — Theory meets experiment

Date: Jan 2, 2015

Author: spectroscopyNOW

The calculated dynamics and energetics of water at interfaces or in biological systems have been verified by measured time-resolved infrared spectra.

Journal Highlight: Monitoring early hydration of cement by ex situ and in situ ATR-FTIR – a comparative study

Date: Dec 1, 2014

Author: spectroscopyNOW

A previously validated ex situ freeze-dry procedure to stop hydration at preset times is complemented by an in situ ATR-FTIR spectroscopy method to provide insights into early cement hydration.

The meta the better: Improving IR and molecular spectroscopy

Date: Dec 1, 2014

Author: David Bradley

US researchers have found that confined surface phonon polaritons within the material hexagonal boron nitride give rise to metamaterial properties that might one day be exploited in enhanced infrared and molecular spectroscopy.

Journal Highlight: Early detection of heterotopic ossification using near-infrared optical imaging reveals dynamic turnover and progression of mineralization following Achilles tenotomy and burn injury

Date: Nov 5, 2014

Author: spectroscopyNOW

Non-invasive near-infrared optical imaging was used to detect and monitor heterotopic ossification in mice given an Achilles tenotomy in combination with a dorsal burn or sham procedure.

Skin deep damage: UV exposure

Date: Nov 1, 2014

Author: David Bradley

Ultraviolet light damages DNA and cause proteins in the body to break down into smaller, sometimes harmful pieces that may also damage DNA, increasing the risk of skin cancer and cataracts. UV-IR double-resonance photofragment spectroscopy now reveals the details.

Journal Highlight: Assessment of crystallinity in processed sucrose by near-Infrared spectroscopy and application to lyophiles

Date: Oct 6, 2014

Author: spectroscopyNOW

The capability of near-infrared spectroscopy to determine crystallinity in processed sucrose was studied using a common set of calibration standards derived from binary physical mixtures.

Gas: Of the organic interstellar kind

Date: Oct 1, 2014

Author: David Bradley

A carbon-based molecule that is not the usual fodder of interstellar dust has been detected in a giant gas cloud some 27000 light years from earth. The discovery offers a new hint as to the origins of the complex organic molecules that were the building blocks of life in our planet's primordial soup.

Journal Highlight: Exploring bacterial phenotypic diversity using factorial design and FTIR multivariate fingerprinting

Date: Sep 15, 2014

Author: spectroscopyNOW

Bacterial phenotypic diversity of cultures of Staphylococcus aureus grown under variable sets of environmental conditions was characterized by FTIR spectroscopy, using different spectral preprocessing methods in combination with scaling methods in principal component analysis.
