In this paper, we theoretically analyze steady-state thermoelectric transport through a single-molecule junction with a vibrating bridge. The thermally induced charge current in the system is explored using a nonequilibrium Green function formalism. We study the combined effects of Coulomb interactions between charge…
Abstract In this paper, a generalisation of previous author’s formulation of fractional continuum mechanics for the case of anisotropic non-locality is presented. The discussion includes a review of competitive formulations available in literature. The overall concept is based on the fractional deformation gradient wh…
Abstract Magnesium alloys are used predominantly for high-pressure die-cast applications in which the use of a deliberate heat treatment is uncommon. This article provides information on the heat treatment designations for magnesium alloys. It describes the effects of grain size on magnesium alloys and the relationshi…
Electric noise can be an important limitation for applications of conducting elements in the nanometer size range. The intrinsic electrical noise of prospective materials for opto-spintronics applications like ZnO has not yet been characterized. In this study, we have investigated the conductivity fluctuations in 10 n…
The effective medium theory is applied to model a layered biaxial anisotropic material with different orientations. Basing on the same reflection and transmission coefficients, equivalent model is developed to calculate effective permittivity, permeability and orientation angle for two layers of anisotropic media. Wit…
HfSe2is a layered semiconductor relevant for two-dimensional (2D) field effect transistors (FETs), with recent reports of a bulk band-gap comparable to Silicon (Eg~ 1.1 eV) [1,2] and oxidation into the high-K insulator HfO2[1,3]. However, extreme environmental sensitivity has prevented device measurements in samples b…
Abstract Gluing of wood with great moisture content has challenge of water interaction with glue to give unwanted changes in glue properties and formed bond-line. Rheological measurements of polyurethane glues are sufficiently effective method to understand the polymer curing process and viscoelastic properties. Gel f…
Abstract Spontaneous electroless deposition of ultrafine metal nanoparticles (NPs) supported on covalent organic frameworks (COFs) for catalytic organic transformation is rarely reported. Herein, poly(phenylene butadiynylene)s (PPBs), a easily prepared two‐dimensional (2D) covalent organic frameworks (COFs) consisting…
Various polymer alloys have been examined to achieve performance beyond that of single polymers. Polyamide 6 (PA6) has extraordinary mechanical properties, impact absorbability, and high heat resistance necessary for exterior and interior automotive applications. Nevertheless, some materials and their combinations can…
This work considers a nearly spherical bubble and a nearly flat free surface interacting under buoyancy at vanishing Bond number Bo. For each perturbed surface, the deviation from the unperturbed shape is asymptotically obtained at leading order on Bo. The task appeals to the normal traction exerted on the unperturbed…
Two unprecedented mixed B(III) /P(V) complexes of meso-triaryl 25-oxasmaragdyrins were synthesized in appreciable yields under mild reaction conditions. These unusual 25-oxasmaragdyrin complexes containing one or two seven-membered heterocyclic rings comprised of five different atoms (B, C, N, O, and P) were prepared…
Chiral nanostructures show macroscopic optical activity. Local optical activity and its handedness are not uniform in the nanostructure, and are spatially distributed depending on the shape of the nanostructure. In this study we fabricated curved chain nanostructures made of gold by connecting linearly two or more arc…
Pistagremic acid (PA) is a bioactive triterpenoid isolated from various parts of Pistacia integerrima plants. The aim of this research was to investigate PA for reversion of multidrug resistant (MDR) mediated by P-glycoprotein using rhodamine-123 exclusion study on a multidrug resistant human ABCB1 (ATP-binding casset…
Objective: The main objective of this study was to explore co-crystallization as an effort to enhance the solubility of simvastatin (SV) using tartaric acid (TA) as co-former. Methods: The simulation of molecular modeling of TA against SV has been done by in silico using auto dock 4.2. A preparation of co-crystal carr…
The rise of DC nanogrids distribution system allows for lower component count, higher overall system efficiency and an ease of integration with renewable energy sources and DC battery storages. In a built environment, the retrofitting to extra-low voltage direct current (ELVDC) for distribution seems promising for res…
Synthesis of TiO 2 -Al 2 O 3 -SiO 2 nanopowder composite, as well as composite coating on soda lime glass and Si (100) by sol-gel method is reported. The morphology and the crystal structure of composite are characterized by the use of field emission scanning electron microscopy (FE-SEM), Energy dispersive X-ray (EDAX…
The hydrogenation of carbon dioxide over the catalyst comprised of Fe and Cu (Fe-Cu catalyst) was studied at 523-673 K under 5 MPa using a flow-type fixed-bed reactor. The main products were carbon monoxide, hydrocarbons, and alcohols. The hydrocarbon products were followed by the Schulz-Flory-Anderson distribution la…
Switched reluctance machine (SRM) has attracted more attention recently for its simple structure and high reliability. In this paper, an analytical method for solving the magnetic field in SRM is illustrated utilizing the Schwarz-Christoffel conformal mapping method. With the help of Matlab SC tools, a general radial…

The methodology of this work introduces a new model, which related density of tetrazolium nitrate salts to the numb…
Silver nanoparticles of many types are widely used in consumer and medical products. The surface chemistry of particles and the coatings that form during synthesis or use in many types of media can significantly impact the behaviors of particles including dissolution, transformation and biological or environmental imp…
