Influence of milling parameters on particle size of ulexite material
(Elsevier Science BV, 2016)
Commercial raw ulexite (U) materials were milled from 0 h to 8 h by using mechanical milling technique for var-ious initial powder size (−3mm;−75μm), ball to powder ratio (5:1; 10:1), and ball size (10 mm; 5 mm). Par-ticle ...
Experimental determination of cooling performance on heat sinks with cone-jet electrospray mode
(Elsevier - Division Reed Elsevier India Pvt Ltd, 2021)
In this study, electrospray cooling characteristics for smooth surface heat sink and finned surface heat sink were investigated. An experimental study was carried out using ethanol for 7 different heat fluxes in the cone-jet ...
Determining and mapping of natural and artificial radioactivity from moss samples in Artvin (Turkey)
(Parlar Scientific Publications, 2020)
In this study, moss samples which have radiologic indicator characteristic were collected from 80 stations in Artvin to determine the natural (Ra-226, Th-232, and K-40) and artificial (Cs-137) radioactivity levels. Natural ...
Spatial characteristics of ecological and health risks of toxic heavy metal pollution from road dust in the Black Sea coast of Turkey
(Elsevier, 2021)
The purpose of this study was to investigate the toxic heavy metal (Cd, Cr, Cu, Ni, Pb, Zn) concentrations of dust samples from the Black Sea coastal road in the north of Turkey. The Black Sea coastal road was represented ...
Structure, magnetization, specific heat, and microwave properties of KxFe2-ySe2
(IOP Publishing Ltd, 2016)
Temperature-dependent magnetization, specific heat, and magnetic field modulated microwave spectroscopy (MFMMS) measurements were performed on single crystals of KxFe2-ySe2. Magnetization measurements yield a superconducting ...
Investigation of superconducting and normal-state properties of the filled-skutterudite system PrPt4Ge12-xSbx
(Amer Physical Assoc, 2016)
We report a study of the superconducting and normal-state properties of the filled-skutterudite system PrPt4Ge12-xSbx. Polycrystalline samples with Sb concentrations up to x = 5 were synthesized and investigated by means ...
An investigation of magnetoresistivity properties of an Y3Ba5Cu8Oy bulk superconductor
(Elsevier Science BV, 2015)
A bulk ceramic superconducting sample was fabricated using the standard solid state reaction (SSR) method in the stoichiometric ratio of Y:Ba:Cu:O (3:5:8). The electrical and microstructural properties of the sample were ...
