The presence of hydrogen in the weld metal or HAZ may lead to a form of cracking known as hydrogen-induced cracking (HIC). This form of cracking is also commonly referred to as "hydrogen-assisted cracking" (HAC) or "cold cracking" since it occurs at or near room temperature after the weld has cooled. This form of crac…

Phosphorene is a novel two-dimensional material that can be isolated through mechanical exfoliation from layered black phosphorus, but unlike graphene and silicene, monolayer phosphorene has a large band gap. It was thus unsuspected to exhibit band inversion and the ensuing topological insulator behavior. It has recen…
Battelle Energy Alliance, LLC, has successfully tested a remote welding process to seal radioactive waste containers prior to hot isostatic pressing (HIP). Since the 1990s, a variety of radioactive and hazardous waste forms have been remotely treated using HIP during trials within Idaho National Laboratory (INL) hot c…
After an introduction to polysaccharides in general and cationic polysaccharides in particular, a short overview on different fields of applications in regenerative medicine is given. Applications are manifold and range from wound healing and artificial skins to guided nerve and bone regeneration. However, the scope o…
This work has as object of study the energy of a river ship air conditioning system performance, using fiberglass, polyurethane or rockwool as insulation. Thermoeconomics Indicators based on second law of thermodynamics which take into account the quality of the energy and the cost of the exergy were used for research…
Many of graphene’s interesting properties originate from its unique dispersion relations around the K point, a high symmetry point in the Brillouin zone (BZ), where two bands cross over each other linearly. In this paper, we study the Dirac-cone-like dispersion relations around the low symmetry points in the BZ of a c…
In recent years, magnesium alloys have emerged as possible biodegradable implant material. A fundamental understanding of the nature of magnesium corrosion and the ability to control this process in vivo is critical to advancing the case for clinical use of magnesium based biomaterials. The biodegradation of magnesium…
Multidrug resistance (MDR) occurs in prostate cancer, and this happens when the cancer cells resist chemotherapeutic drugs by pumping them out of the cells. MDR inhibitors such as cyclosporin A (CsA) can stop the pumping and enhance the drugs accumulated in the cells. The cellular drug accumulation is monitored using…
Gas turbine, steam turbine and heat engine (Stirling engine) is used as bottoming cycle for a solid oxide fuel cell plant to compare different plants efficiencies, CO2 emissions and plants cost in terms of $/kW. Each plant is then integrated with biomass gasification and finally six plants configurations are compared…
Solar Thermoelectric Generators (STEGs) convert solar energy to electricity. The solar energy is first used to heat an absorber plate that serves as the high temperature reservoir. Power is generated by connecting the hot reservoir and cold (ambient) reservoirs with a pair of p- and n-doped thermoelectric legs. Experi…
In order to make clear the mechanism of the directional coarsening (rafting) of γ′ phases in Ni-base superalloys under uni-axial tensile strain, molecular dynamics (MD) analysis was applied to investigate dominant factors of strain-induced anisotropic diffusion of Al atoms and nanotexture change of fine dispersed γ′ p…
It is demonstrated through the nonequilibrium Green’s function method that the interfacial thermal resistance (Ω) of graphite can be modulated by loading pressure in x direction, x and y directions and all three directions respectively in this paper. For graphite without pressure, the interfacial thermal resistance is…

Abstract The present investigation deals with the determination of temperature profile and subsequent rates of cooling at certain points on the external surface along axis of an ERW pipe, during TIG welding. Two samples of different diameters of pipes of ASTM A 106 Gr. B, seamless type are selected for experimentation…
