Abstract: The possibility of vanadium carbide coating formation on AISI L2 steel was studied in molten salt bath containing 33 wt% NaCl- 67 wt% CaCl2. In this research, the effects of time, temperature and bath composition on growing layer thickness were studied. The vanadium carbide coating treatment was performed in the NaCl-CaCl2 bath at 1173, 1273 and 1373 K temperatures for 3, 6, 9 hours a...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

The aim of this study was to evaluate the dosimetric characteristics a semi-customized tongue displacement device ( SC TDD) fabricated using 3D printer for patients receiving unilateral head and neck irradiation with intensity-modulated proton therapy (IMPT) assess its feasibility as beam stopper compared standard mouthpiece S MP). Seven consecutive patients, three tonsil cancer, four oral cavi...

in this study, plasma electrolytic oxidation of 2024-t3 aluminum alloy was investigated. the electrolyte used in this investigation was an alkaline solution containing additives of silicate, phosphate, potassium hydroxide and glycerin. a conventional dc power source with a low applied voltage was employed. corrosion resistance of the oxide layer was investigated by means of tafel plots and elec...

We study the frictional drag due to Coulomb and phonon mediated electron–electron interaction in a double layer electron system exposed to a perpendicular magnetic field. We calculate the transresistivity as a function of magnetic field, temperature, and inter-layer spacing L: We find the strikingly different magnetic field and temperature dependence of the transresistivity for L 1⁄4 30 and 200...

A HSQ/PMMA bilayer resist system, in which HSQ as negative tone electron beam resist top layer and PMMA as bottom layer, has been investigated for negative tone lift-off process. Patterns are first defined on the HSQ resist using electron beam lithography, and then transferred into the bottom PMMA layer using oxygen reactive ion etching. Electron beam exposure of HSQ on top of PMMA layer has be...

FeSe layer-based superconductors exhibit exotic and distinctive properties. The undoped FeSe shows nematicity and superconductivity, while the heavily electron-doped KxFe2-ySe2 and single-layer FeSe/SrTiO3 possess high superconducting transition temperatures that pose theoretical challenges. However, a comprehensive study on the doping dependence of an FeSe layer-based superconductor is still l...

introduction: the purpose of this study was to determine the effects of citrus aurantifolia (ca) extract on smear layer removal in different parts of root canals. materials and methods: thirty-nine single-rooted human teeth were randomly divided into three experimental ( n =12) and one control ( n =3) groups. teeth were instrumented using mtwo rotary instruments. root canals were irrigated with...
