Journal Highlight: Classification of lignocellulosic biomass by weighted-covariance factor fuzzy C-means clustering of mid-infrared and near-infrared spectra

Date: Mar 20, 2017

Author: spectroscopyNOW

A weighted-covariance factor fuzzy C-means clustering method combined with bootstrapping has been proposed for analysing the mid-IR and near-IR spectra of small samples of biomass.

Colorectal cancer prognosis: Imaging mass spectrometry of tissue microarrays

Date: Mar 16, 2017

Author: Steve Down

The life expectancy of people suffering from colorectal cancer has been linked to a number of signals derived from imaging mass spectrometry, which are also associated with the aggressiveness of the tumour.

Catching makers of crystal meth by chemometrics

Date: Mar 15, 2017

Author: Ryan De Vooght-Johnson

Identifying impurities in the illegal drug N-methylamphetamine, a.k.a. methamphetamine or crystal meth, can help law enforcement agencies detect the likely source and the synthetic route used. Scientists from the Chemistry and Chemical Engineering Research Centre of Iran used chemometric methods to detect trace impurities hidden under the large main peak in pure samples of seized methamphetamine.

Heavy metal from cars: Statistical analyses of spectra

Date: Mar 15, 2017

Author: David Bradley

Multivariate statistical techniques, principal component analysis (PCA), and hierarchical cluster analysis have been used to process data on metal pollutants in a densely populated city based on atomic absorption spectra.

Elemental analysis: Hair by AAS

Date: Mar 15, 2017

Author: David Bradley

Atomic absorption spectrometry (AAS) has been used to analyse hair samples from Polish children and adolescents revealing significant differences between metallic elements present in different age groups and between boys and girls.

Record-breaking crystals: Smallest ever X-rayed

Date: Mar 15, 2017

Author: David Bradley

The crystalline protein envelope of an insect virus has been examined by high-intensity X-ray pulses. The study by Henry Chapman of the Center for Free-Electron Laser Science id described in the Proceedings of the National Academy of Sciences and represents the smallest protein crystals examined so far by X-ray crystallography.

What a difference a state makes: NMR curiosity

Date: Mar 15, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has revealed how molecular self-assembly processes can take different forms of a supramolecular structure from the solution state to the solid state and back again, a phenomenon identified for the first time by researchers at the University of Warwick, UK.

Journal Highlight: Analysis of soluble components in coals and interpretations for the complex mass spectra

Date: Mar 13, 2017

Author: spectroscopyNOW

Soluble products from the thermal dissolution of Chinese coals have been analyzed by LC/MS, revealing the distributions of isomers to describe the content inequality of organic species within the same class of coal molecules.

Journal Highlight: Data fusion of fluorescence and UV spectroscopies improves the detection of cocoa butter adulteration

Date: Mar 13, 2017

Author: spectroscopyNOW

Fluorescence and UV spectroscopies have been used synergistically for the detection of cocoa butter adulteration with cocoa butter equivalents, using principal component regression models.
