Effects of orientation on the shape memory behavior of Ni51Ti49 single crystals
(Elsevier Science Sa, 2017)The orientation dependence of the shape memory responses of [001], [011] and [111]-oriented Ni51Ti49 single crystals and Ni50.8Ti49.2 polycrystals are systematically studied in compression. Thermal cycling under constant ... -
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. ... -
Electronic, phononic, and thermoelectric properties of graphyne sheets
(Amer Inst Physics, 2014)Electron, phonon, and thermoelectric transport properties of a-, b-, c-, and 6,6,12-graphyne sheets are compared and contrasted with those of graphene. a-, b-, and 6,6,12-graphynes, with direction dependent Dirac dispersions, ... -
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 ... -
Enhancing the Damping Behavior of Dilute Zn-0.3Al Alloy by Equal Channel Angular Pressing
(Springer, 2017)The effect of grain size on the damping capacity of a dilute Zn-0.3Al alloy was investigated. It was found that there was a critical strain value (ae1 x 10(-4)) below and above which damping of Zn-0.3Al showed dynamic and ... -
Equilibrium limit of thermal conduction and boundary scattering in nanostructures
(Amer Inst Physics, 2014)Determining the lattice thermal conductivity (kappa) of nanostructures is especially challenging in that, aside from the phonon-phonon scattering present in large systems, the scattering of phonons from the system boundary ... -
Gate induced monolayer behavior in twisted bilayer black phosphorus
(IOP Publishing LTD, 2017)Optical and electronic properties of black phosphorus strongly depend on the number of layers and type of stacking. Using first-principles calculations within the framework of density functional theory, we investigate the ... -
Harmonised method for impact resistance requirements of E-glass fibre/unsaturated polyester resin composite railway car bodies
(Elsevier Sci LTD, 2018)This paper shows for the first time an approach to harmonise and unify various railway standards into a single method for small object strike against rail vehicles. Emerging composite materials applications for structural ... -
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 ... -
The influence of surface functionalization on thermal transport and thermoelectric properties of MXene monolayers
(Royal Soc Chemistry, 2018)The newest members of a two-dimensional material family, involving transition metal carbides and nitrides (called MXenes), have garnered increasing attention due to their tunable electronic and thermal properties depending ... -
Influence of tantalum additions on the microstructure and shape memory response of Ti50.5Ni24.5Pd25 high-temperature shape memory alloy
(Elsevier Science Sa, 2014)A Ti50.5Ni24.5Pd25 (at%) high-temperature shape memory alloy (HTSMA) was alloyed with 1, 3, and 5 at% Ta additions in an effort to enhance the shape memory properties, particularly the dimensional stability for actuator ... -
