Hydrogenated amorphous silicon carbide layers are deposited using an inductive-coupled plasma-enhanced chemical vapour deposition process. The nominal thickness of the thin films is 300 nm and the chemical composition ranges from carbon rich to pure Si films by varying the silane to methane ratio χ. The compressive re…
Novel hierarchical hollow ZnO microspheres, composed of large ZnO crystals on the outer surfaces and small ZnO crystals on the inner surfaces, were synthesized by a chemically induced self-transformation process, employing the ester elimination between zinc formate dihydrate and ethanol.
As one of the building blocks of the cell membrane, lipids and their interaction with neighboring lipids and other molecules, as well as their ability to form different kinds of structures, have garnered immense interest. By exploiting the effective shape and thermal-phase behavior of lipids, we have prepared lipid su…
Computational investigation of nitrous oxide cleavage by metal-amide systems has shown that a bimetallic mechanism is compatible with the remarkable experimental observation of selective N-N bond scission by a di-molybdenum system, and that the interplay between the bonding energetics of reactants and products can bot…
Members of the family Methanosarcinaceae are important archaeal representatives due to their broad functionality, ubiquitous presence, and functionality in harsh environments. A key characteristic is their multicellular (packet) morphology represented by aggregates of spatially confined cells. This morphology is drive…
Aluminium‐doped zinc oxide (AZO) nanorods thin films were grown by RF magnetron sputtering on gold (Au) metal catalyst. The Au catalyst layers with 5, 10, and 15 nm thickness were deposited on glass substrates by sputtering method followed by annealing for 15 min at 500°C to form Au nanostructures on the glass substra…
This paper presents experimental results in study of hydrogen redistribution in technically pure titanium alloy under X-ray exposure at room temperature. It is demonstrated that X-ray exposure to titanium with hydrogen affects hydrogen diffusion and redistribution from the surface area to the depth of the samples irre…
Photovoltaics based on inorganic thin film absorber layers such as CuInS 2 (CIS) are showing promise in overcoming the increasing energy demand. There are, however, challenges that CIS presents before it can be considered cost effective. A typical synthesis employs a high temperature (∼500°C) annealing step with a H 2…

Hollow poly(urea-formaldehyde) microcapsules are vacuum infiltrated with a reactive amine curing agent. They are used in dual capsule epoxy-amine healing chemistry to produce thermally stable self-healing epoxy polymers by Scott R. White and co-workers on page 282. Autonomic healing in excess of 90% is achieved in a h…
The residues generated in the furniture industry have not yet been optimally used for panel production. One reason for this is that residues from the furniture industry contain high-density hardwood, which is not considered suitable as a raw material in panel production. In this study, the possibility of high-density…
With the continues improving of people's living standards, more and more people work out in all kinds of sports fields beyond the busy work. On the other hand, the development of the modern competitive sports also requires that the sports experts should not only strive for the scientific training, but should also pay…
Understanding hydrogen transport and trapping phenomena is a key feature to revisit the hydrogen embrittlement (HE) models proposed in the literature. Both aspects can be affected by stress-strain states at different microstructural scales. Elastic distortion and plastic strain are both aspects of the mechanical state…

Flexible coaxial thin thread supercapacitors were fabricated semi-automatically using a dip coating method. A typical coaxial thin thread supercapacitor of a length of 70 cm demonstrated a specific length capacitance of 0.3 mF cm−1 (11.2 mF cm−2 and 2.18 F cm−3) at 5 mV s−1, the device exhibited good electrochemical p…
The focusing of electromagnetic waves from a quartic inhomogeneous chiro-slab is examined, using Maslov’s method. Analytic field expressions are derived for the transmission coefficients at the interfaces and numerical computations are made to determine the field behavior around the caustic point of the chiro-slab. Th…
We present our results of a local probe study on EuFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$ single crystals with $x$=0.13, 0.19 and 0.28 by means of muon spin rotation and ${}^{57}$Fe M\"ossbauer spectroscopy. We focus our discussion on the sample with $x$=0.19 viz. at the optimal substitution level, where bulk superconducti…
The large single crystal diamonds are successfully synthesized in a NiMnCo-C system with the zinc additive in a series of the experiments at temperatures of 1270-1400 ℃ and pressures of 6.2-6.4 GPa by the temperature gradient growth. Morphology and structural properties of the synthesized diamond are characterized by…
Graphene synthesis by chemical-vapor-deposition (CVD) has attracted great interest. As the substrates for graphene growth, copper has become a common choice because its capacity could produce high-quality and uniform monolayer graphene. Morphology and surface conditions of the copper foil have great influence on the q…
Porous aluminum alloys produced by the metal-gas eutectic method or GASAR process need to be performed under a certain pressure of hydrogen, and to carry over melt to a tailor-made apparatus that ensures directional solidification. Hydrogen is driven out of the melt, and then the quasi-cylindrical pores normal to the…
