Improvement the wear behavior of low carbon steels by friction stir processing
(IOP Publishing LTD, 2017)
A low carbon structural steel was surface-hardened by friction stir processing (FSP) through 4 mm thickness from the surface. The hardness of the alloy increased from 140 Hv0.1 to about 240 Hv0.1 after single-pass FSP. ...
Electronic and mechanical properties of stiff rhenium carbide monolayers: A first-principles investigation
(Elsevier Science BV, 2018)
In this study, we predicted two new stable metallic Re-C based monolayer structures with a rectangular (r-ReC2) and a hexagonal (h-Re2C) crystal symmetry using first-principle calculations based on density functional theory. ...
In pursuit of barrierless transition metal dichalcogenides lateral heterojunctions
(IOP Publishing LTD, 2018)
There is an increasing need to understand interfaces between two-dimensional materials to realize an energy efficient boundary with low contact resistance and small heat dissipation. In this respect, we investigated the ...
Engineering electronic properties of metal-MoSe2 interfaces using self-assembled monolayers
(Royal Soc Chemistry, 2014)
Metallic contacts are critical components of electronic devices and the presence of a large Schottky barrier is detrimental for an optimal device operation. Here, we show by using first-principles calculations that a ...

Thermal properties of black and blue phosphorenes from a first-principles quasiharmonic approach
(Amer Physical Soc, 2015)
Different allotropes of phosphorene are possible of which black and blue phosphorus are the most stable. While blue phosphorus has isotropic properties, black phosphorus is strongly anisotropic in its electronic and optical ...
Assessment on lattice thermal properties of two-dimensional honeycomb structures: Graphene, h-BN, h-MoS2, and h-MoSe2
(Amer Physical Soc, 2014)
The linear thermal expansion coefficients of two-dimensional honeycomb structures graphene, h-BN, h-MoS2, and h-MoSe2 are systematically studied by using first-principles based quasiharmonic approximation. This approach ...
A solar desalination plant for conditions in Turkey
(1989)
In this study, it is supposed that a solar desalination plant has been installed in Antalya (36.5°N, 30.1°E), Turkey. The solar radiation incident on the ground has been determined and then an energy equilibrium has been ...
An investigation of heat transfer gain with introduction of graphite powder to helium gas
(1993)
Analysis is made of heat transfer by turbulently flowing helium gas with suspended graphite particles in a circular pipe. At very high temperatures, the radiative heat to gas alone can be profoundly improved because of the ...
Numerical computation of turbulent flow in pipes
(1993)
Developing turbulent flow in pipes of circular cross-section with length-to-diameter ratio of 100 has been computed at eight Reynolds numbers ranging from 3.8 X10 "SUP 4" to 3.88 X10 "SUP 5" . Numerical solutions of the ...
