Raman Microspectroscopy of HAYABUSA Particle RA-QD02-0197

چکیده
Raman microspectroscopy measurements were performed on Hayabusa sample RA-QD02-0197. The sample has been provided by JAXA to our consortium in the scope of the 1 International Announcement of Opportunity [1]. Raman microspectroscopy is an appropriate technique for a contactless mineralogical investigation and is applied to describe the mineralogical composition of the sample. For the noble gas research proposed in the project [2] it is essential that the sample does not come in contact with the Earth atmosphere. Therefore, the sample has been stored in a container filled with nitrogen and has been investigated through a quartz window. Olivine, pyroxene, and feldspar are the minerals that could be identified.

متن کاملMultifocus confocal Raman microspectroscopy for rapid single-particle analysis.
We have developed a multifocus confocal Raman microspectroscopy system that allows simultaneous analyses of ≈ 80 individual biological or airborne microparticles based on a precise image-guided technique. Multiple individual particles adhered in random positions on a coverslip were illuminated by a multifocus excitation pattern formed by rapidly steering a single laser beam with a pair of galvo...
متن کاملIn Situ Detection of Antibiotic Amphotericin B Produced in Streptomyces nodosus Using Raman Microspectroscopy
The study of spatial distribution of secondary metabolites within microbial cells facilitates the screening of candidate strains from marine environments for functional metabolites and allows for the subsequent assessment of the production of metabolites, such as antibiotics. This paper demonstrates the first application of Raman microspectroscopy for in situ detection of the antifungal antibio...
متن کاملOrientation-distribution mapping of polycrystalline materials by Raman microspectroscopy.
Raman microspectroscopy provides the means to obtain local orientations on polycrystalline materials at the submicrometer level. The present work demonstrates how orientation-distribution maps composed of Raman intensity distributions can be acquired on large areas of several hundreds of square micrometers. A polycrystalline CuInSe2 thin film was used as a model system. The orientation distribu...
متن کاملShining light on the microbial world the application of Raman microspectroscopy.
Raman microspectroscopy is a noninvasive, label-free, and single-cell technology for biochemical analysis of individual mammalian cells, organelles, bacteria, viruses, and nanoparticles. Chemical information derived from a Raman spectrum provides comprehensive and intrinsic information (e.g., nucleic acids, protein, carbohydrates, and lipids) of single cells without the need of any external lab...
