Last Month's Most Accessed Feature: Biodiesel analysis: Biofuel blend by NMR spectroscopy

A new quantitative method of analysing the biodiesel in a diesel-biodiesel blend using proton nuclear magnetic resonance spectroscopy has been developed by researchers in Brazil. The resulting spectra are subjected to a univariate calibration in which the integrals of the spectra are considered. Statistical comparison with infrared (IR) spectra corroborate the findings.

Gelsemium elegans is a toxic plant of interest for its possible medical uses. Scientists from Hunan Agricultural University in China used a combination of LC-MS/MS and an in-house database of the accurate masses of previously detected Gelsemium compounds to tentatively identify a wide range of the many components in a crude extract from the plant.

Researchers from Aarhus University in Denmark and the Institute of Science and Technology in Austria have developed a new technique for aligning molecules using lasers and ultracold droplets of helium so they can precisely measure alignment.

A novel diagnosis method for distinguishing Alzheimer disease, mild cognitive impairment and healthy states used kernel PCA followed by LDA and a a multi-kernel SVM for training and testing for detection.
