High Resolution Image Download MS PowerPoint Slide Combination of an oxide semiconductor with a highly conductive nanocarbon framework (such as graphene or carbon nanotubes) is an attractive avenue to assemble efficient photoelectrodes for solar fuel generation. To fully exploit the possible synergies of the hybrid fo…
The intermediate filament vimentin is required for cells to transition from the epithelial state to the mesenchymal state and migrate as single cells; however, little is known about the specific role of vimentin in the regulation of mesenchymal migration. Vimentin is known to have a significantly greater ability to re…
Graphene oxide (GO) was rarely used as microwave absorption (MA) material due to its lower dielectric loss compared with reduced GO (RGO). However, the characteristics of low conductivity, light weight, and large surface area were beneficial to the impedance matching for absorbers already containing highly conductive…
Upon mechanical stimulation, 9-anthryl gold(I) isocyanide complex 3 exhibited a bathochromic shift of its emission color from the visible to the infrared (IR) region, which is unprecedented in its magnitude. Prior to exposure to the mechanical stimulus, the polymorphs 3α and 3β exhibit emission wavelength maxima (λ em…
Recently, issues concerning the sustainable and harmless disposal of organic solid waste have generated interest in microbial biotechnologies aimed at converting waste materials into bioenergy and biomaterials, thus contributing to a reduction in economic dependence on fossil fuels. To valorize biomass, waste material…
A general method is proposed to produce oriented and highly crystalline conducting polymer layers. It combines the controlled orientation/crystallization of polymer films by high‐temperature rubbing with a soft‐doping method based on spin‐coating a solution of dopants in an orthogonal solvent. Doping rubbed films of r…
Graphene-like single- or few-layer semiconductors, such as dichalcogenides and buckled nanocrystals, possess direct and tunable bandgaps, and excellent electrical, optical, mechanical and thermal properties. This unique set of desirable properties of 2D semiconductors has triggered great interest in developing ultra-t…
Abstract Single‐source precursor syntheses have been devised for the preparation of structurally similar graphitic carbon dots (CDs), with (g‐N‐CD) and without (g‐CD) core nitrogen doping for artificial photosynthesis. An order of magnitude improvement has been realized in the rate of solar (AM1.5G) H 2 evolution usin…
Three‐dimensional (3D) printing, a layer‐by‐layer deposition technology, has a revolutionary role in a broad range of applications. As an emerging advanced fabrication technology, it has drawn growing interest in the field of electrochemical energy storage because of its inherent advantages including the freeform cons…
The analogy between charge carriers scattering in disordered spin structure of conductors and in polar disordered structure of dielectrics is noted and confirmed. When moving in spin-disordered structure, electrons scattering increases and becomes very large in case of opposite-spin structure of anti-ferromagnetics. O…
In this paper, metamaterials are regarded as a kind of specific medium. The application of three-dimensional electromagnetic field finite element mesh generation methods makes a finite element analysis and calculates the integral to metamaterials and its surrounding spatial structures so as to solve the spatial distri…
Based on the analysis of dissipative processes in solids, the factors which determine the magnitude of internal friction in silica glasses have been highlighted and the main principles of the synthesis of silica glass with low internal friction have been stated. In accordance with the developed principles, the process…
Several ceramic rolls can be used efficiently to produce high quality zinc coated steel sheet used for automobiles. Those ceramics rolls may provide a longer life and reduce the cost for the maintenance because of its large heat resistance and large wear resistance. One example may be seen in sink rolls used in molten…
Abstract It is well known that drillstring failures are a pendent problem in drilling engineering, because of the fatigue accumulation caused by the low amplitude-repeated impact. In order to reveal the effect of low amplitude-repeated impact on the failure mechanism of the drillstring, a repeated impact method and in…
With the help of our molecular dynamics simulation we want to motivate emerging and development of technological methods for building of carbon nanostructure networks. We shall study self-organizing behaviors of graphene nanoribbons in Y-junctions. We determine the conditions for perfect formation of nanotube Yjunctio…
ABSTRACT Graphene and graphene doped with CeO 2 were prepared and characterized by FTIR, BET, XRD, SEM and elemental analysis. Adsorption of 2-nitrophenol by graphene and cerium doped graphene (CeO 2 @ graphene nanocomposite) was studied. The impact of different parameters such as effect of adsorbent dosage, contact t…
Bismuth nickel niobate was prepared by conventional solid state reaction technique. Dense ceramic body was obtained at low sintering temperatures.

Shape memory alloys (SMA) have been the subject of several studies due to their excellent physical and mechanical properties. For this reason, a wire SMA is used in various applications as thermomechanical actuators that are subject to repeated thermal cycling in a range of temperatures and variable loads. The mechani…
