This paper presents results of the structure analysis and tribological testing of a-C:H type diamond-like carbon (DLC) coatings produced by the Plasma Assisted Chemical Vapour Deposition (PACVD) technology on CoCrMo specimens.The DLC coating structure was studied by observing the surface topography using a scanning el…
We investigate theoretically the nonequilibrium transport properties of a topological insulator quantum dot (TIQD) in the Coulomb blockade and Kondo regime. An Anderson impurity model is applied to a TIQD system coupled to two external leads, and we show that the model realizes the spin-orbital Kondo effect at the Dir…
For this research, we studied the influence of titanium tetrachloride (TC) and titanium tetraisopropoxide (TTP) precursors on CaTiO3 (CTO) synthesis by employing a microwave-assisted hydrothermal (MAH) method regarding their respective short-, medium- and long-range features to determine if the use of different titani…
The end corrosion in steel girders at the bearings due to joint leakage is a significant problem in many of the old bridges around the nation. This critical damage impairs the shear and bearing capacities of girders. This paper discusses a novel method for retrofitting the corroded ends of steel bridge girders using u…
We study the effects of GaN interlayer on the transport properties of two-dimensional electron gases confined in lattice-matched AlInN/AlN/GaN heterostructures. It is found that the Hall mobility is evidently enhanced when an additional ultrathin GaN interlayer is introduced between AlInN and AlN layers. The enhanceme…
Abstract AuN films were produced on 304 stainless steel using an arc‐pulsed – assisted plasma physical vapor deposition system. The deposition was performed using an Au target in a nitrogen atmosphere at different pressures. The films were characterized using x‐ray photoelectron spectroscopy and x‐ray diffraction. A 3…
It is known that covalent semiconductors become superconducting if conveniently doped with large concentration of impurities. In this article we investigate, using ab initio methods, if the same situation is possible for an ionic, large-band gap semiconductor such as ZnO. We concentrate on the cage-like sodalite phase…
The self-compensation effect in Si-doped Al 0.55 Ga 0.45 N layers was investigated using different SiH 4 /III ratios. The degree of compressive strain changed with SiH 4 flow rate during growth. With a low SiH 4 /III ratio of 2.46 × 10 −6 , compressive strain was increased in comparison with the un-doped case. However…
Our objective was to determine the limiting flux and serum protein (SP) removal at 8, 9 and 10% true protein (TP) in the retentate recirculation loop using 0.1-µm ceramic graded permeability (GP) microfiltration (MF) membranes with 3mm channel diameters (CD). An additional objective was to compare the limiting flux an…
Abstract Programmable molecular self‐assembly of siRNA molecules provides precisely controlled generation of dendrimeric siRNA nanostructures. The second‐generation dendrimers of siRNA can be effectively complexed with a low‐molecular‐weight, cationic polymer (poly(β‐amino ester), PBAE) to generate stable nanostructur…
This paper aims to study the effect of processing temperature on interfacial behavior of HKT800 carbon fiber composites with epoxy and Bismaleimide (BMI) matrix. Referring to the processing conditions of the composite, various processing-heat treatments were conducted on HKT800 and the extracted sizing content decline…
The fluorescent diaminoterephthalate scaffold was equipped by amidation with three types of reactive functions: thiols for metal-surface binding, alkynes for click reactions, and maleimides for ligation with proteins. Starting from a succinyl succinate derivative with two orthogonally cleavable ester functions, three…
Hydromorphology and Biodiversity in Headwaters — An Eco- Faunistic Substrate Preference Assessment in Forest Springs of the German Subdued Mountains
Single crystals of the SrGeO3 (strontium germanium trioxide) high-pressure phase have been synthesized successfully at 6 GPa and 1223 K. The compound crystallizes with the ideal cubic perovskite-type structure (space group Pm-3m), which consists of a network of corner-linked regular GeO6 octa-hedra (point-group symmet…
In this article, we report a durable coating of polyester fabric with carbon nanotubes. Four fabric samples were prepared using different treatments to obtain the fabric with the lowest electrical resistance. Plasma treatment was performed to prepare the fabric surface for depositing amino functionalized carbon nanotu…
New pyrotechnic smoke compositions, containing only environmentally benign materials, have been demonstrated to produce thick white smoke clouds upon combustion. These compositions use powdered boron carbide (B 4 C) as a pyrotechnic fuel, KNO 3 as a pyrotechnic oxidizer, and KCl as a combustion temperature moderator.…
With the increasing scarcity of wood as a natural resource, bamboo has become a popular substitute for wood. The present work developed a high-strength original state multi-reorganization material (GPEHB), without the use of a hot press or traditional assembly. The original bamboo units were polygonized into outer con…
An experimental investigation was carried out on chloride induced corrosion of steel bars in concrete under marine en-vironment with the variation of micro-structure of steel-concrete interface. To create the variation of micro-structure of steel-concrete interface, steel bars coated with cement paste of different W/C…
Vertical zinc oxide (ZnO) thin-film transistors (TFTs) with submicrometer channel length have good performance, including large current density (>10 mA/mm), high mobility (> 14 cm2/Vs), and large current ON-OFF ratio (>107). They also have asymmetric current-voltage (I-V) characteristics in the saturation region when…
Abstract Synthesis of terpenyl selenides derived from limonene, menthol, caranol, and myrtanol is described. Three methodologies for the synthesis of terpenyl selenonium salts are compared. The results of selenium‐mediated epoxidation through the use of isoselenocineole derived from limonene and methyl terpenyl, pheny…
