MGS-TES Spectra Suggest a Basaltic Component in the Regolith of Phobos
(Amer Geophysical Union, 2018)
Plain Language Summary The origins of the Martian moons Phobos and Deimos have been the subjects of considerable debate. Visible and near-infrared spectra of these bodies are dark and nearly featureless, with red slopes ...
Three-Dimensional Raman Tomographic Microspectroscopy: A Novel Imaging Technique
(Amer Geophysical Union, 2018)
Chemical constituents and their spatial distributions in terrestrial and extraterrestrial samples may provide clues to their formation histories and secondary processes they were subjected to. Most analytical tools are ...
Microstructure, Mechanical and Corrosion Properties of UNS 32205 Duplex Stainless Steel Weldment Joints by Multipass FCAW
(Walter De Gruyter Gmbh, 2021)
In this study, the effect of multipass welding on the microstructure, mechanical and corrosion properties of the UNS 32205 duplex stainless steels (DSS) is investigated. The UNS 32205 DSS is welded in 3 or 7 passes by ...
Investigation of carbonates in the Sutter's Mill meteorite grains with hyperspectral infrared imaging micro-spectroscopy
(Pergamon-Elsevier Science Ltd, 2018)
Synchrotron-based high spatial resolution hyperspectral infrared imaging technique provides thousands of infrared spectra with high resolution, thus allowing us to acquire detailed spatial maps of chemical molecular ...
Biconical reflectance, micro-Raman, and nano-FTIR spectroscopy of the Didim (H3-5) meteorite: Chemical content and molecular variations
(Wiley, 2020)
The Didim meteorite contains multiple lithologies and clasts of different petrologic types in a single stone. A mixture of H5 clasts in an unequilibrated H3 host was previously observed in Didim, according to the initial ...
Carbonaceous matter in the Saricicek meteorite
(Wiley, 2019)
As of today, the Saricicek (SC) meteorite is the newest howardite and the only confirmed fall among the 17 known howardites. In this study, we present isotopic, infrared, and Raman data on three distinct pieces of the SC ...
Nano-FTIR spectroscopic identification of prebiotic carbonyl compounds in Dominion Range 08006 carbonaceous chondrite
(Nature Portfolio, 2021)
Meteorites contain organic matter that may have contributed to the origin of life on Earth. Carbonyl compounds such as aldehydes and carboxylic acids, which occur in meteorites, may be precursors of biologically necessary ...
