Structure characterization of films from drying oils cured under infrared light

Date: Apr 1, 2010

Author:

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.

NIR focus on energy molecule

Date: Mar 1, 2010

Author: David Bradley

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.

Determination of simple sugars, malic acid and total phenolic compounds in apple pomace by IR spectroscopy and PLSR

Date: Mar 1, 2010

Author:

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.

Cosmic coronene's phantom spectral bands

Date: Feb 1, 2010

Author: David Bradley

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.

A noninvasive near IR system for detection of platelet components contaminated with bacteria

Date: Feb 1, 2010

Author:

This study describes near infrared spectroscopy to examine platelets inoculated with low concentrations of Bacillus cereus and Staphylococcus epidermidis, comparing with sterile bags.

A highly sensitive near-IR fluorescent detection method to analyze signalling pathways by reverse-phase protein array

Date: Jan 4, 2010

Author:

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.

The violin case

Date: Jan 1, 2010

Author: David Bradley

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.

Prediction of 13C and 15N in plant tissues with near-infrared reflectance spectroscopy

Date: Dec 2, 2009

Author:

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.

Resonant approach to quantum problem

Date: Dec 1, 2009

Author: Steve Down

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.

Quick assessment of the thermal decomposition behavior of lignocellulosic biomass by near IR spectroscopy and its statistical analysis

Date: Nov 2, 2009

Author:

The application of near infrared spectroscopy for predicting the thermal decomposition behavior of lignocellulosic biomass (three types of woody biomass and three types of herbaceous biomass) was successfully performed along with statistical analysis.
