Journal Highlight: Measurement of the concentration of nutrients in grapevine petioles by attenuated total reflectance FTIR spectroscopy and chemometrics

Date: Jun 2, 2014

Author: spectroscopyNOW

The effectiveness of attenuated total reflectance Fourier transform infrared spectroscopy as a rapid and low-cost method for measuring the concentration of nutrients in grapevine petioles has been examined.

Laser-guided fruit flies: Thermal control

Date: Jun 1, 2014

Author: David Bradley

The movements and behaviour of fruit flies, genetically engineered to carry a heat-sensitive ion channel, can be controlled with a precisely aimed infrared laser. The fruit fly, Drosophila melanogaster, is widely used as a model organism for biological and biomedical research and so such puppetry should allow the species to be studied more easily than ever before.

Journal Highlight: Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectral discrimination of brain tumour severity from serum samples

Date: May 5, 2014

Author: spectroscopyNOW

ATR-FTIR spectral data have been combined with a RBF-SVM statistical analysis for the diagnosis and differentiation of high-grade and low-grade brain tumours and non-cancerous tissue.

So NIR: And yet so far

Date: May 1, 2014

Author: David Bradley

German researchers have used near infrared spectroscopy (NIRS) to monitor blood flow in the brains of six climbers scaling Mount Kilimanjaro in Tanzania, with a view to understanding and hopefully preventing headaches caused by altitude sickness.

Journal Highlight: Thermal and chemical analysis of flammability and combustibility of fir wood in cone calorimeter coupled to FTIR apparatus

Date: Apr 4, 2014

Author: spectroscopyNOW

The thermal degradation of fir wood was studied in a cone calorimeter under well-ventilated atmosphere with the exhaust gases analysed by FTIR spectroscopy.

Stroke monitoring: NIR gets in the patient's head

Date: Apr 1, 2014

Author: David Bradley

A near-infrared monitoring device has been developed by scientists at the University of Pennsylvania, Philadelphia. The system could be used for bedside monitoring of cerebral blood flow in ischemic stroke patients with a view to ensuring optimal treatment and improved outcomes in a potentially debilitating and often lethal condition.

Journal Highlight: Infrared spectroscopic characterization of carbonated apatite: A combined experimental and computational study

Date: Mar 3, 2014

Author: spectroscopyNOW

A combined experimental and computational approach was employed to investigate the feasibility and effectiveness of using IR spectroscopy to characterise carbonated apatites prepared from synthetic and biological material.

Microreactions: Need microspectroscopy

Date: Mar 1, 2014

Author: David Bradley

In situ infrared and X-ray high spatial-resolution microspectroscopy have been used for the first time to track multistep organic transformations in a flow microreactor in which gold nanoclusters act as the catalyst.

Journal Highlight: Infrared spectra of protonated coronene and its neutral counterpart in solid parahydrogen: Implications for unidentified interstellar infrared emission bands

Date: Feb 3, 2014

Author: spectroscopyNOW

IR absorption spectra of protonated and mono-hydrogenated coronene, produced upon electron bombardment of parahydrogen containing coronene during matrix deposition, were discussed in terms of interstellar unidentified infrared emission bands.

Fire: Home is where the hearth is

Date: Feb 1, 2014

Author: David Bradley

Humans began using fire probably around 1 million years ago, but new infrared spectroscopic work by an Israeli team suggests that we built our first hearths to give us more control over fire about 300,000 years ago.
