Journal Highlight: Use of near-IR spectroscopy to distinguish carbon and nitrogen originating from char and forest-floor material in soils: usefulness of a genetic algorithm
Date: Oct 3, 2011
Author:
The potential of a genetic algorithm for spectral feature selection and interpretation of near-IR spectra in soil science studies was examined for predicting C and N from char and forest-floor material and compared with a partial least squares method.

Porous boron: Heralding hydrogen economy
Date: Oct 1, 2011
Author: David Bradley
Researchers in Europe have developed a hydrogen storage material based on porous magnesium borohydride that can safely adsorb large quantities of the gas via both a physical and a chemical mechanism. They used X-ray diffraction, infra-red and Raman spectroscopy to investigate this material.

Journal Highlight: Examining the phonological neighborhood density effect using near infrared spectroscopy
Date: Sep 6, 2011
Author:
Neurobehavioral correlates of phonological neighborhood density in skilled readers of English have been explored using near infrared spectroscopy, showing that words with many neighbors elicited significantly greater changes in blood oxygenation in the left than in the right hemisphere of the brain.

Infrared dwarf: Icy world of slushy volcanoes
Date: Sep 1, 2011
Author: David Bradley
US astronomers have used infrared techniques to reveal that the dwarf planet, nicknamed Snow White, is an icy world half covered in water ice that once spewed from slush volcanoes. Their data also hints that the planet has an atmosphere of methane, that is gradually evaporating into space.

Journal Highlight: Measurement of the variation of crystal lattice structures of ethylene copolymers with high-resolution cryogenic FTIR spectroscopy
Date: Aug 2, 2011
Author:
A high-resolution cryogenic FTIR study of the variation of unit cell volume of ethylene-octene copolymers found that both the comonomer content and thermal history have great influence on the crystal lattice structure of ethylene polymers.

Pores for thought: Zeolite catalysts open wide
Date: Aug 1, 2011
Author: David Bradley
Researchers in China have developed a new process for making zeolite catalysts with wide open pores. Their controllable synthesis leads to materials active in the conversion of methanol to propylene with a high, 98%, conversion rate.

Journal Highlight: Understanding inverse oxygenation responses during motor imagery: a functional near-IR spectroscopy study
Date: Jul 4, 2011
Author:
Wireless functional near-infrared spectroscopy was performed over secondary motor areas during performance of motor imagery and motor execution in 11 healthy subjects, who either executed or imagined two drawing tasks differing in shape and frequency.

Glowing grains: NIR ID for parathyroid glands
Date: Jul 1, 2011
Author: David Bradley
Researchers have discovered that the parathyroid glands - four small organs each the size of a grain of rice located at the back of the throat - glow with a natural fluorescence in the near infrared. The finding has led to the development of an optical detector for highlighting the glands during endocrine surgery to avoid damage to these essential organs.

Journal Highlight: The application of visible/near-infrared reflectance (VNIR) spectroscopy to chert: A case study from the Dover Quarry sites, Tennessee
Date: Jun 6, 2011
Author:
The application of visible/near-infrared reflectance spectroscopy to chert sourcing attains a cost-efficient, fast, non-destructive, and accurate means of identifying material type and geologic/geographic origin, exemplified by a case study from the Dover Quarry sites, Tennessee.
