Abstract Physical and numerical simulations of the hot rolling and laminar cooling of DP steel strips are presented in the paper. The objectives of the paper were twofold. Physical simulations of hot plastic deformation were used to identify and validate numerical models. Validated models were applied to simulate the…
The broad application of microbial electrolysis cells (MECs) requires a system characterized by low cost and high operational sustainability. Biocathode MECs, which only require bacteria as the cathode catalysts, can satisfy these demands and have attracted considerable attention in recent years. In this study, we hav…
The properties of nanostructured materials differ significantly from chemically identical bulk materials. The phase transitions in these materials are of a complex nature since the size of the particles is a crucial parameter. In this paper, the series of phase transitions occurring during the gaseous nitriding of nan…
A two-dimensional superconductor with spin-triplet p -wave pairing supports chiral or helical Majorana edge modes with a quantized (length L -independent) thermal conductance. Sufficiently strong anisotropy removes both chirality and helicity, doubling the conductance in the clean system and imposing a super-Ohmic dec…
The surface treatment of zinc stannate (Zn2SnO4) film for use in dye-sensitized solar cells has been carried out with zinc tin oxide precursor solutions through chemical-bath deposition (CBD). Mott–Schottky measurements demonstrate that the flat band of Zn2SnO4 has a moderate positive shift owing to the surface treatm…
We report a facile and efficient electrostatic spray route to fabricate novel Cr-loaded NiO core-in-hollow-shell structured micro/nanospheres without any templates or surfactants. On the basis of different influencing factors including solvent evaporation rate and temperature-dependent solute degradation process, a mu…
Abstract Crystalline molecular sieves are used in numerous applications, where the properties exploited for each technology are the direct consequence of structural features. New materials are typically discovered by trial and error, and in many cases, organic structure‐directing agents (OSDAs) are used to direct thei…
A 30 kVA, 96000 r/min, air-cooled high-speed permanent-magnet generator (HSPMG) is investigated in this paper. Considering effects on both the magnetic circuit and heat transfer paths comprehensively, the stator slot notch in this HSPMG is optimized. First, using the time-stepping finite-element method, the transient…
In this work, we present time-dependent density functional theory calculations of the excited-state geometries and electronic properties of both model cyanines and BODIPY derivatives, which are particularly challenging dyes for theoretical chemistry. In particular, we focus on environmental effects, using a panel of a…
In the paper, the analyses of Fe2p3/2 and chromium Cr2p3/2 XPS spectra with fitting by symmetrical and asymmetrical line shapes, are presented. The calculations are performed on AISI 316L SS biomaterial after magnetoelectropolishing MEP operation. The best results were obtained for fitting by GL(30) and by LA(1,3; 4;…
Abstract A series of 4f–5f heteronuclear metallic complexes were synthesized by a hydrothermal route from mixtures of uranyl acetate, lanthanide nitrate, and 1,2,4,5‐benzenetetracarboxylic acid (H4BTA) in an aqueous system. Single‐crystal X‐ray analysis revealed that the thirteen UO2‐Ln‐BTA complexes ([(UO2)1.5Ln(C10O…
Abstract A series of Cu–CuxO, Pt–Cu alloy, and Pt nanoparticles supported on inexpensive activated carbon with large surface area were developed as electrocatalysts for the reduction of nitrobenzene. This reaction can produce useful chemicals with the potential to cogenerate electricity if applied in a fuel cell. Both…
Transparent and highly conductive indium-zinc oxide (IZO) was utilized as a metallic capping layer in solution-processed indium-gallium-zinc oxide (IGZO) thin-film transistors (TFTs) to enhance their electrical performance. By applying an in-situ metallic oxide (IZO) as a capping layer, which can be monolithically pat…
A critical analysis was carried out for the purpose of understanding the role of subcolloidal (nanosized) (alumino)silicate precursor species in the early stage of crystallization of zeolites in heterogeneous systems (hydrogels). The formation and evolution of these subcolloidal species in both the solid and the liqui…
The electron channeling contrast imaging technique was used to investigate the microstructure of copper coatings fabricated by cold gas dynamic spray. The high velocity impact characteristics for cold spray led to the formation of many substructures, such as high density dislocation walls, dislocation cells, deformati…
Using flat-histogram Monte Carlo methods, we investigate the adsorptive behavior of the square-well fluid in two simple slit-pore-like models intended to capture fundamental characteristics of flexible adsorbent materials. Both models require as input thermodynamic information about the flexible adsorbent material its…
The hierarchical zeolite with MFI nanosheet frameworks was directly prepared under hydrothermal synthesis conditions using a series of tetra-headgroup rigid bolaform quaternary ammonium surfactants, where the bolaform surfactants act as dual structure-directing functions on two different length scales (micro- and meso…
In this study, we demonstrated the intercalation of Na in hydrothermally synthesized VOx nanotubes (NTs) and Ni-doped VOx NTs. The changes induced in the structures of the two nanomaterials during the Na intercalation process were investigated through X-ray diffraction (XRD) analyses. It was observed that the initial…
In this work, a well-dispersed Au cluster/reduced graphene oxide (RGO) composite was synthesized using citric acid (CA) as a reducing and binding agent. The as-prepared composite was systemically characterized by TEM, XPS, TGA and FTIR. TEM image showed Au clusters uniformly distributed on the RGO sheet with an averag…
Bioreactors have been widely acknowledged as valuable tools to provide a growth environment for engineering tissues and to investigate the effect of physical forces on cells and cell-scaffold constructs. However, evaluation of the bioreactor environment during culture is critical to defining outcomes. In this study, t…
