ExoMars Rover To Look For Microbial Life
2013-09-10 14:49:55

John P. Millis, PhD for redOrbit.com - Your Universe Online In 2018, the European Space Agency (ESA) will launch a new mission to Mars called ExoMars. Armed with new instruments, this explorer will beam back information about various conditions and properties on the Red Planet’s surface. One such instrument will be the Raman spectrometer – a device similar to a bomb detector that will search for evidence for life. The Raman spectrometer has the ability to detect life that has been...

CSI Technique Avoids Forensic Evidence Contamination
2013-08-09 05:02:59

April Flowers for redOrbit.com - Your Universe Online One of the chief concerns at any crime scene investigation is avoiding contamination of forensic evidence. A new study by forensic scientists at the University of Kent, UK, has established a new method of identifying the brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag. The researchers used a technique called Raman spectroscopy that detects laser light. This technique will allow...

Innovative Software Automates Particle Location and Chemical Characterization EDISON, N.J., July 15, 2013 /PRNewswire/ -- HORIBA Scientific (HORIBA), the global leader in Raman spectroscopy systems, is proud to announce the launch of their new ParticleFinder module for the LabSpec 6 Spectroscopy Suite. ParticleFinder was developed as part of a collaboration with Particle Sciences, Bethlehem, PA, to support their client drug product formulation and analytic, bioanalytic, physical...

Testing Mars Lasers In Desert
2013-06-25 10:18:28

Michael Harper for redOrbit.com – Your Universe Online Looking for the closest representation of otherworldly environments on Earth? Look no further than the Atacama desert. It covers a large strip of the Pacific coast west of the Andes, spanning four South American countries. One swath of this desert found in Chile is commonly compared to the Martian surface and has been used by NASA to test tools designed to search for life in a harsh environment. Now, scientists from Washington...

Scientists Image The Molecular Structure Of Polymer Blends
2012-11-28 15:30:26

National Institute of Standards and Technology (NIST) Using an enhanced form of "chemical microscopy" developed at the National Institute of Standards and Technology (NIST), researchers there have shown that they can peer into the structure of blended polymers, resolving details of the molecular arrangement at sub-micrometer levels. The capability has important implications for the design of industrially important polymers like the polyethylene blends used to repair aging waterlines....

'BRIGHTS' Reveal Location Of Targeted Tissues
2012-11-21 10:41:38

Washington University in St. Louis Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location. Tiny as they are, the probes are exquisitely engineered objects: gold nanoparticles covered with molecules called Raman reporters, in turn covered by a thin shell of gold that spontaneously forms a dodecahedron. The Raman reporters are molecules whose...

Enhanced local electric fields are predominant in nonlinear optical properties, particularly in surface-enhanced Raman scattering (SERS), which is a sensitive technique used for the detection of trace amounts of chemicals. Analysis of the electric fields around nanostructures indicates that they can provide a basic foundation to obtain greater SERS intensity. Professor ZHANG Zhongyue and his group from the College of Physics and Information Technology at Shaanxi Normal University have...

Finding Explosives With Laser Beams
2012-02-28 04:12:23

Scientists at Vienna University of Technology have found a way to detect chemicals over long distances, even if they are enclosed in containers People like to keep a safe distance from explosive substances, but in order to analyze them, close contact is usually inevitable. At the Vienna University of Technology, a new method has now been developed to detect chemicals inside a container over a distance of more than a hundred meters. Laser light is scattered in a very specific way by...
