Journal Highlight: Fourier transformed near infrared (FT-NIR) spectroscopy for the estimation of parameters in pretreated lignocellulosic materials for bioethanol production

Date: Jun 29, 2015

Author: spectroscopyNOW

Prediction models were developed with FT-NIR spectroscopy and multivariate analysis for the cellulose crystallinity index, saccharification and ethanol yield, and glucan, hemicellulose and lignin content of two pulps.

Journal Highlight: The effect of ageing on fMRI: Correction for the confounding effects of vascular reactivity evaluated by joint fMRI and MEG in 335 adults

Date: Jun 22, 2015

Author: spectroscopyNOW

The resting-state fluctuation amplitude in the fMRI signal in neural measurements is modulated by measures of vascular function and is not driven solely by changes in the variance of neural activity.

Journal Highlight: Utilization of PARAFAC-modeled excitation-emission matrix (EEM) fluorescence spectroscopy to identify biogeochemical processing of dissolved organic matter in a northern peatland

Date: Jun 15, 2015

Author: spectroscopyNOW

The fluorescent properties of dissolved organic matter in fens and bogs in a Northern Minnesota peatland were studied using excitation-emission matrix fluorescence spectroscopy with parallel factor analysis, identifying four humic-like components and one protein-like component.

Separation anxiety: Magnetic metal recycling

Date: Jun 15, 2015

Author: David Bradley

Rare earth magnets are widely used in a range of gadgets, instrumentation and even toys but recycling the mixtures of metals from which the magnets are formed is difficult. Now, research published in the journal Angewandte Chemie offers a novel approach to the isolation of neodymium and dysprosium from dismantled magnets. The technique could ward off a future shortage of these metals.
