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 ... -

(Pergamon-Elsevier Science Ltd, 2020)The bulk interior of Kemer L4 ordinary chondrite was characterized for the first time by means of optical microscopy, scanning electron microscopy with energy dispersive spectroscopy, Raman spectroscopy, X-ray diffraction, ... -
Diffusion of the Airport Health Accreditation Program in the COVID-19 period: An Assessment with Institutional Logic And Legitimacy Approach
(Elsevier Sci Ltd, 2021)The purpose of this study is to reveal the reason for the diffusion of Airports Health Accreditation among airports. Institutional logic and legitimacy literature are used in the research. The research area consists of 56 ... -
Investigation of carbon in the Allan Hills A77278 meteorite via 2D and 3D Raman microspectroscopy
(Wiley, 2018)This paper reports the first Raman spectral and imaging data on the ordinary chondrite Allan Hills A77278 (ALHA77278) in two and three dimensions. Mineralogy in the ALHA77278 meteorite appears to be mainly silicates (olivine ... -
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 ... -
Investigation of drying kinetics of viscose yarn bobbins
(2011)This study is concerned with the investigation of the suitability of several empirical and semi-empirical drying models available in the literature to define drying behavior of viscose yarn bobbins. For this purpose, ... -
Late magmatic - hydrothermal tourmaline occurrences within leucogranites in NW Anatolia (Turkey): Mineral chemistry and genetic implications
(Elsevier Gmbh, 2021)Numerous Oligo-Miocene plutonic and associated aplite-pegmatite rocks occur in the Western Anatolian Magmatic Complex. However, only the plutons of Namazgah, Karadag, Sogucak and Karadoru, in the Biga Peninsula, host three ... -
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 ... -
Microstructure, mechanical and corrosion properties of nickel superalloy weld metal
(Walter De Gruyter Gmbh, 2021)Inconel 625 alloy is used in aggressive environments at high temperatures such as in petro-chemical applications, in the aeronautical and nuclear energy industries because of its propitious mechanical properties and corrosion ... -
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 ... -
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 ... -
Nanoscale Infrared Characterization of Dark Clasts and Fine-Grained Rims in CM2 Chondrites: Aguas Zarcas and Jbilet Winselwan
(American Chemical Society, 2021)Carbonaceous chondrites are among the most primitive meteorites that escaped extreme temperatures and melting in their parent bodies and, as such, offer valuable records of the parent body origins, formation, and evolution. ... -
Suitability of drying models in defining hotair drying behaviour of polyester based yarn bobbins
(2011)In this study, the suitability of several empirical and semi-empirical drying models available in the literature to define drying behaviour of polyester based yarn bobbins has been investigated. For this purpose, firstly, ... -
Synchrotron-Based FTIR Micro-spectroscopy of Martian Meteorites
(2018)Martian meteorites from SNC group were studied with synchrotron-based FTIR spectroscopy with ~1 µm spatial resolution in the mid-infrared region (4000-850 cm-1). Silicate region in EET A79001, ALH 84001, and Nakhla present ... -
Thermal metamorphic history of Antarctic CV3 and CO3 chondrites inferred from the first- and second-order Raman peaks of polyaromatic organic carbon
(Mineralogical Soc Amer, 2021)Parent body thermal metamorphism is an important process that alters the structure of organic matter in the parent asteroid of meteorites. Increasing and progressing thermal metamorphism results in carbonization and ... -
