Journal Highlight: Two-photon fluorescent imaging of myelination in the spinal cord

Date: Dec 10, 2012

Author: spectroscopyNOW

The myelin-targeted fluorescent imaging agent Case Imaging Compound has been synthesized via an improved route and evaluated as a probe for two-photon fluorescent imaging of myelin in the spinal cord in both demyelinated and dysmyelinated models.

A sense of Mars: Atmospheric probe

Date: Dec 1, 2012

Author:

A remote sensing instrument that will peer into the ultraviolet to offer clues to how Mars might have lost its atmosphere has arrived at Lockheed Martin for integration into NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Journal Highlight: Anthradithiophene-thiophene copolymers with broad UV-vis absorption for organic solar cells and field-effect transistors

Date: Nov 12, 2012

Author: spectroscopyNOW

The optical, electrochemical, structural, field-effect transistor, and solar cell properties of novel anthradithiophene-thiophene semiconducting copolymers have been investigated.

Metal chameleon: Red, gold and green, by George!

Date: Nov 1, 2012

Author: David Bradley

Researchers in the UK have demonstrated how embossing or indenting tiny patterned features on to the surface of a piece of gold or other metals can change the way they reflect light and so allow them to make gold appear red and green instead of its familiar, lustrous yellow colour.

Journal Highlight: Macular thickness and volume of myopic eyes measured using spectral-domain optical coherence tomography

Date: Oct 8, 2012

Author: spectroscopyNOW

The macular thickness and volume of young myopic eyes were measured by spectral-domain optical coherence tomography to show that thinner macular thickness, lower macular volume and thicker foveal thickness are associated with longer axial length.

Well insulated: Conducting experiments

Date: Oct 1, 2012

Author: David Bradley

Extreme ultraviolet radiation has been used to shed light on the fundamental differences between different types of electrically insulating materials with femtosecond time-resolved photoelectron spectroscopy.

Journal Highlight: Optical spectroscopy and multivariate analysis for biodosimetry and monitoring of radiation injury to the skin

Date: Sep 10, 2012

Author: spectroscopyNOW

A simple spectroscopic method, such as optical reflectance spectroscopy, can be used with multivariate data analysis for the rapid and noninvasive in vivo diagnosis and monitoring of cutaneous radiation exposure.

ChemCam's mega blast: Martian rock succumbs

Date: Sep 1, 2012

Author: David Bradley

The ChemCam instrument aboard NASA's Curiosity rover recorded its first spectra on Mars in mid-August, giving the systems a little target practice but also demonstrating that the device is working as it should by providing a sneak preview of rocky spectra.

Journal Highlight: Non-destructive evaluation of ripening and quality traits in apples using a multiparametric fluorescence sensor

Date: Aug 13, 2012

Author: spectroscopyNOW

A fluorescence-based portable sensor was used for the non-invasive determination of chlorophylls, anthocyanins and flavonols in several apple cultivars.

Damaged goods: Probing the depths

Date: Aug 1, 2012

Author: David Bradley

Electronic devices are susceptible to damage from radiation, potentially cosmic radiation and even ultraviolet radiation. A study using coherent acoustic phonon spectroscopy (CAPS) reveals that the amount of optical damage, as opposed to structural damage, that can be caused may be more than ten times greater than studies suggested.
