According to the theories of the solid physics and irreversible thermodynamics, the performance characteristics of a novel high-efficient graphene thermionic power device (TPD) are studied. The temperature of the cathode plate and anode plate are determined by solving the energy balance equation of hot and cold sides…
Recently, layered oxychalcogenide has attracted significant scientific attention because of its intriguing electronic properties, intrinsically low thermal conductivity and, correspondingly, outstanding thermoelectric properties, of which the BiCuSeO possesses the best thermoelectric performance ever reported. For ins…
The nature of crystallization is considered to be one of the most fundamental research problems in condensed matter physics. With single particle resolution offered by video microscopy, colloidal suspensions provide a novel model system for studying crystallization, melting and other phase transitions, where the struc…
An optimization method is used to obtain the longest effective afterglow time in the rare earth ions doped long lasting phosphors. The effective afterglow time is defined as the time for the intensity to decays to 10% of the initial intensity. In this paper, we choose the Eu2+ and Dy3+ coped Sr2MgSi2O7 as the experime…

NiTi shape memory alloy has been widely used in industrial and biological fields due to its excellent mechanical properties, unique shape memory effect and superelasticity. In this paper, the atomic relaxation, thermodynamic energy, structural stability, electronic structures and other properties of all low-index surf…
The determination of the critical breakdown path in slightly uneven electric field has played a significant role in gas discharge starting process and electrode surface erosion. In order to study the law of the critical path position in the low-pressure breakdown case, a new algorithm based on the Monte-Carlo collisio…
The volume expanding magnetostructural transition in Mn3GaC and Mn3SnC has been identified to be due to distortion of Mn6C octahedra. Despite a similar lattice volume as Mn3SnC and similar valence electron contribution to density of states as in Mn3GaC, Mn3InC does not undergo a first order magnetostructural transform…
Micron-scale fragment ejection of metal is a kind of surface dynamic fragmentation phenomenon upon shock loading. The study of ejecta is crucial in many fields, such as inertial confinement fusion and pyrotechnics. Due to the particular advantages of laser experiments, a lot of studies of ejecta by strong laser-induce…
The paper deals with solving the mechanic connected problems applying to residual stresses under non-stationary thermal effects. The research is aimed at the electromechanical processing technology in the application to titanium pseudo-α-alloys which change their phase composition due to the martensitic phase transiti…
We report on beating appearance in Shubnikov–de Haas oscillations in conduction band of 18–22 nm HgTe \nquantum wells under applied top-gate voltage. Analysis of the beatings reveals two electron concentrations at the \nFermi level arising due to Rashba-like spin splitting of the first conduction subband H₁. The diffe…
Countries using nuclear energy tend to favour disposal of Low-Level and Intermediate-Level radioactive waste in mined repositories consisting of series of tunnels or drifts connected to disposal tunnels at a few hundred meters depth. Abandoned mines can serve as repositories for such waste and the present study indica…
Union fabric is the fabrics where the warp yarns are different from weft yarns. Eri silk and wool is the way to incorporate better appearance in the woolen fabric and to increase the utility of silk fabric. Eri with wool union fabrics was found to be better quality in respect of physio-mechanical properties. The plain…
A hollow cylinder with thick walls is one of the most complex objects to calculate the unsteady temperature field, so this field is the least studied. However, such objects are found in many modern constructions of systems of generation and distribution of heat. In the proposed work it deals with the study of propagat…
This paper presents an empirical analysis on the use of aqueous extract of Dodonaea angustifolia for the production of silver nanoparticles (AgNPs) from aqueous silver nitrate. The Dodonaea angustifolia leaf extract, AgNPs and Diclofenac sodium at different concentrations was incubated with egg and Bovine serum albumi…
Introduction Bisphenol-A (BPA), an estrogenic compound, is used in the manufacture of polycarbonate plastics and epoxy resins. Sesame oil (SO) is a potent antioxidant dietary source for human health.Aim The present study was conducted to estimate the protective effects of SO against BPA-induced cardiotoxicity.Material…
Periclase is the terminal component of the ferropericlase, and its chemical composition is MgO. It is well known that there exists a huge difference between the melting curves of MgO determined experimentally and theoretically. A feasible way to clarify the nature of the melting temperature is to investigate the possi…
A mathematical model is constructed to describe a steady one-dimensional temperature distribution in a hollow circular cylinder made of a polymer dielectric with a constant difference in the electric field potentials on the cylinder surfaces. Based on systematized data on the dependence of the thermal conductivity and…
Using first-order shear deformation theory (FSDT), a semi-analytical solution is employed to analyze creep damage and remaining life assessment of 304L austenitic stainless steel thick (304L ASS) cylindrical pressure vessels with variable thickness subjected to the temperature gradient and internal non-uniform pressur…
