The application of the biomaterial dielectrics made of thermally crosslinking natural proteins without any additives in fabricating organic electronics is highlighted. The gate dielectrics of organic field-effect transistors (OFETs) are prepared by the thermal treatment of the chicken albumen film taken directly from…
The quantitative excited energy transfer reaction between cationic porphyrins on an anionic clay surface was successfully achieved. The efficiency reached up to ca. 100% owing to the "Size-Matching Rule" as described in the text. It was revealed that the important factors for the efficient energy transfer reaction are…
Abstract Here, we report, for the first time, on the Raman spectra of Ti 2 AlN, Ti 2 AlC 0.5 N 0.5 , (Ti 0.5 V 0.5 ) 2 AlC, Ti 3 AlC 2 , and Ti 3 GeC 2 and compare the results with those of Ti 2 AlC and V 2 AlC reported previously. The first‐order mode peaks of the end members are narrower than those of their respecti…
Mono- and few-atomic-layered BN and Cx-BN nanosheets are fabricated in high yield through the blowing B- and N-containing polymers into large, thin-walled bubbles by chemically released hydrogen gas followed by subsequent annealing.
Chemical reactions of linear trimethylsilyl-terminated poly(dimethylsiloxane)s with the surfaces of oxidized silicon, titanium, aluminum, and nickel are reported. These reactions lead to covalently attached poly(dimethylsiloxane) polymer chains and to hydrophobized inorganic surfaces. Linear silicones of this type (si…
An investigation was carried out into the hydrolysis of cellulose dissolved in 1-ethyl-3-methylimidazolium chloride ([Emim][Cl]) and 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]) catalyzed by mineral acids. Glucose, cellobiose, and 5-hydroxymethylfurfural (5-HMF) were observed as the primary reaction products. The…
High critical temperature superconductors have zero power consumption and could be used to produce ideal electric power lines. The principal obstacle in fabricating superconducting wires and tapes is grain boundaries—the misalignment of crystalline orientations at grain boundaries, which is unavoidable for polycrystal…
Nanotheranostics represents the next generation of medicine, fusing nanotechnology, therapeutics, and diagnostics. By integrating therapeutic and imaging agents into one nanoparticle, this new treatment strategy has the potential not only to detect and diagnose disease but also to treat and monitor the therapeutic res…
A facile strategy to synthesize water-soluble fluorescent gold nanoclusters (Au NCs) stabilized with the bidentate ligand dihydrolipoic acid (DHLA) is reported. The DHLA-capped Au NCs are characterized by UV-vis absorption spectroscopy, fluorescence spectroscopy, transmission electron microscopy, and X-ray photoelectr…
PDF | After a period of consolidation in recent years, the world ́s steel markets expand again. Rolling mill owners are well advised to take time by the forelock and upgrade their plant and equipment to the state of the art in technology in order to meet future demands. Looking at the cold rolling capacities installed…
Transition of batchwise nanoparticle production routes to large-scale manufacturing processes is vital for commercialization of such materials. This paper reports the comparison studies from batch and continuous mode for the synthesis of copper nanoparticles by the polyol method. The copper nanoparticles synthesized i…
The magnetic hysteresis loops of Nd 2 Fe 14 B/α-Fe/Nd 2 Fe 14 B exchange-coupling trilayer film are simulated by micromagnetic theory, and the relationship between remanence, coercivity, energy products and soft magnetic thickness are discussed in detail. The results show that the hysteresis loops is rectangle and the…
Glass or carbon fibres are traditionally used as reinforcement in engineering composites. The increasing ecological and environmental concerns have led to the use of natural fibres as renewable alternatives. Among them, hemp fibre offers the best mechanical properties as well as abundant availability. However, the hem…
In this study, the dispersion stabilization characteristics of the poly(vinyl butyral) (PVB) adsorbed yttria-stabilized zirconia (YSZ) was investigated. The addition of PVB showed remarkable dispersion effect to the YSZ slurry prepared with isopropyl alcohol (IPA) and toluene as a bi-solvent system, PVB as a dispersan…
The experimental results showed that the layer is composed of boride zones and transition zones. Boride zones are dense and there are not porosities and micro-crack. The boride zones of carbon steel appear tine-comb by low-temperature boronitriding and consist FeB+Fe2B. The boride zones of alloyed steel appear flat, a…
Since the mid 50’s, interest in research and engineering has been shifting from traditional monolithic materials to fibre-reinforced polymer-based materials due to their unique advantages of high strength-to-weight ratio, non-corrosive properties and high fracture toughness for aerospace and military applications.
Micro-tubular solid oxide fuel cell (SOFC) has been fabricated with NiO-YSZ hollow fiber as anode support and SrFe 0.9 Sb 0.1 O 3−δ -Sm 0.2 Ce 0.8 O 1.9 (SFSb-SDC) composite cathode. The NiO-YSZ hollow fiber anode was prepared by the immersion-induced phase inversion technique and shows a special asymmetrical structur…
The welding processing of Mg-rare earth alloy NZ30K was studied using laser-TIG hybrid welding. For comparison the NZ30K alloy was also welded by the gas tungsten arc (TIG) and laser beam respectively. The microstructure of the welded joints had been analyzed. The hybrid welding method could refine the grains in the f…
We report one-dimensional (1D)- nanostructured ZnO/Cu2O all-oxide inorganic thin film solar cells prepared by electrodeposition from aqueous solutions without thermal treatments and vacuum techniques. The structural morphology of n-type ZnO and p-type Cu2O is customized by adjusting electrodeposition conditions to fit…
MCM-48 microspheres have been repeatedly synthesized in cetyltrimethylammonium bromide-tetraethylorthosilicate-ammonia solution-water media with a fixed alcohol-to-water molar ratio of 0.15 by increasing the amounts of water and ethanol simultaneously. The cubic ordered pore arrangement is proved by the XRD and TEM me…
