This paper presents the main results of performed investigations and discusses the possible influences of different low temperature treatments on relevant material characteristics in correlation with the obtained tooth root bending strength of case-hardened gears made of materials 18CrNiMo7-6, 20MnCr5 and 15NiCr13. Mo…
Two dimensional (2D) alloys, especially transition metal dichalcogenides, have attracted intense attention owing to their band-gap tunability and potential optoelectrical applications. Here, we report the controllable synthesis of wafer-scale, few-layer GaTexSe1-x alloys (0 ≤ x ≤ 1) by molecular beam epitaxy (MBE). We…
An analytical benchmark is proposed for graphene and carbon nanotubes, that may serve to test whatsoever molecular dynamics code implemented with REBO potentials. By exploiting the benchmark, we checked results produced by LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) when adopting the second gene…
Topological defects such as magnetic solitons, vortices, Bloch lines, and skyrmions have started to play an important role in modern magnetism because of their extraordinary stability, which can be exploited in the production of memory devices. Recently, a novel type of antisymmetric exchange interaction, namely the D…
We report experiment and theory on an ambipolar gate-controlled Si-vacuum field effect transistor (FET) where we study electron and hole (low-temperature 2D) transport in the same device simply by changing the external gate voltage to tune the system from being a 2D electron system at positive gate voltage to a 2D hol…
In this work, we report on the fabrication and characterization of n-type c-Si solar cells whose p+ emitters are based on laser processed aluminum oxide/silicon carbide (Al2O3/SiCx) films. The p+ emitter is defined at the rear side of the cell and it consists of point-like laser-diffused p+ regions with a surface char…
In this work, the spinel ZnMn2O4 nanoparticle assemblies have been successfully prepared using a flower-like ZnO as a precursor via a facile a water bath method. The method is a low-cost, simple and large-scale production. The electrochemical performance as Li-ion battery (LIB) materials was tested, the ZnMn2O4 nanopa…
Conductive polymers such as polypyrrole, PPy, are materials capable of conducting electrical current. In this paper two techniques for the electrodeposition of PPy on carbon steel were used: Cyclic Voltammetry (CV) and Chronoamperometry (CA). The characteristics of film electrosynthesized on the carbon-steel substrate…
Fibrous composites, having excellent mechanical properties in the direction of the fibres, have lower mechanical properties in the through thickness direction, controlled by resin. Z-pinning improves the delamination toughness (up to 500%) with a relatively modest reduction to the in-plane mechanical properties (typic…
Conventional electronic devices based on inorganic semiconductor materials (e.g., silicon) are hard, rigid, and flat. Recent advances in mechanics have enabled development of stretchable inorganic electronics on compliant substrates, offering the performance of conventional electronic devices and the ability to deform…
As a complementary role to X-rays, neutrons provide a unique, non-destructive method. Neutron scattering techniques have been widely applied to the determination of the structural details and the dynamics of atomic arrangements in materials and matters. Large-scale scientific facility of neutron scattering has played…

Successfully studies were developed to produce reduced graphene oxide by green reduction of graphene oxide using environmentally-friendly reducing agents. Here for the first time, we report the green reduction of oxidized graphite (OG) to reduced graphene oxide (RGO) using the green plant called Zygophyllum album L.f.…
The adsorption characteristics of ammonia on MSWI bottom ash were investigated. The effect of the variation of the landfill environmental parameters including pH, anions and organic matter on the adsorption process was discussed. Results showed that the adsorption could be well described by pseudo-second-order kinetic…
Electrostatic interaction energy (ΔEEDL) is a part of the Extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory, which, together with van der Waals (ΔEVDW) and acid base (ΔEAB) interaction energies, has been extensively used to investigate the initial adhesion of bacteria to surfaces. Electrostatic or electrical do…
The creep crack problem in damaged materials under mixed mode loading is considered. The class of the self-similar solutions to the plane creep crack problems in a damaged medium under mixed-mode loading is given. With the similarity variable and the self-similar representation of the solution for a power-law creeping…
In the present work, Zn-ZrO2nanocomposite coatings were deposited on the copper substrate through DC and pulse electrodeposition technique with low current density (10 mA/cm2). The effect addition of ZrO2nanoparticles and pulse current were studied. The surface morphology, microhardness and erosion resistance of Zn-Zr…
A solid-state photochemical strategy creates series erasable modulators or optical delay lines within photoresponsive organic microrod waveguides to fine-tune the optical output intensity as a function of delay time. On page 1035, R. Chandrasekar and co-workers show how the photoresponsive waveguide propagates visible…
Abstract A phytochemical investigation of the BuOH‐soluble fraction of the EtOH extract from the stems of Glycosmis pentaphylla resulted in the isolation of three new phenolic glycosides, glycopentosides D–F (1–3, resp.). Their structures were determined by using spectroscopic analysis including UV, 1H‐ and 13C‐NMR, D…
