Experimental and theoretical insights on the structural and optical properties of GeOx thin films deposited via RF magnetron sputtering under varying oxygen percentage
(ELSEVIER, 2023)In this study, GeOx films were produced by radio frequency magnetron sputtering (RFMS) under varying oxygen percentages. The structural and optical properties of films grown have been studied experimentally and theoretical ... -
Formation of Al-Ti-B phases for grain refinement of Al alloys produced by high energy ball milling
(Trans Tech Publications Ltd, 2017)In this experimental study, Al-Ti-B powders were ground in planetary ball mill to produce AlxTiyBz where x, y and z stands for the relative molar ratios of elements for the compilation of grain refiner compound. Powder ... -
Investigation of nitrogen doped ZnO thin films: Effects on their structural and optical properties
(Elsevier, (2021))Un-doped and nitrogen-doped ZnO thin films were grown by using radio frequency (RF) magnetron sputtering method changing the nitrogen flow rate between 0% ����� 12.5% and the thickness dependence of films was determined. ... -
Mineralogy and geochemistry of Paleocene ultramafic- and sedimentary-hosted talc deposits in the southern part of the Sivas Basin, Turkey
(CLAY MINERALS SOC, 2006)Talc deposits, located mainly in three areas of north-central Turkey, are present in the ophiolitic series of the Cretaceous and in siliciclastic rocks of the Paleocene. Talc deposits related to ophiolites are between ... -
Origin of phlogopite occurrences related to ultramafic plutonic rocks in the sivas-yıldızeli area [Sivas-yıldızeli yöresi ultramafik plütonik kayaçlarla ilişkili flogopit oluşumlarının kökeni]
(2016)The different two series/associations as Upper Cretaceous Karakoç plutonics and Paleocene felsic plutonic rocks belonging to Central Anatolian Plutonics are present in the Yıldızeli area. Karakoç plutonics consist of ... -
pH Dependent Degradation and Characterization of Geopolymer Structures Derived from Fly Ash
(POLISH ACAD SCIENCES INST PHYSICS, 2017)Geopolymer structures are a relatively new family of un-fired ceramics that are produced by alkaline slurry of mixed alumina silicate-based materials. One of the most abundant geopolymer-forming powders is the fly ash. Fly ... -
Phase and Morphological Evaluation of Mechanically Activated Sintered YAG Powders
