The plasmon band of Ag nanoplates can be continuously tuned over the visible region by simply stirring with graphene oxide (GO) nanosheets, accompanied with the shape transformation from triangle to round. The ability of GO to competitively adsorb ligands (from Ag nanoplates) has been considered to response for this i…
The pellicle serves as a multifunctional protective layer, providing, e.g., lubrication and remineralization and also acting as a diffusion barrier. In addition, since the formation of the pellicle precedes the adhesion of micro-organisms, it is also important as a conditioning film. We present a novel approach to stu…
Abstract Al-Zn-In anodes show better performance due to the beneficial effects of Zn and In on prevention of aluminum passivity and producing a homogeneous structure for uniform corrosion of the anodes. However, there are different views about the optimum concentration of each element in the anode. In this study, the…
The effect of carbonization on the processing characteristics of rubber seed shell powder was studied. Rubber seed shells were carbonized at different temperatures and then ground into fine powder. The various powders obtained were then characterized by pH, bulk density, moisture content, iodine adsorption value, yiel…
The device parameters of a novel diamond diode, namely, a Schottky-pn diode (SPND), are analyzed to realize a fast switching time, a low on-resistance, and a high blocking voltage simultaneously. The SPND is composed of an n-type active layer sandwiched between a highly doped p+-type layer and a Schottky metal. The ke…
Cationization of different cellulosic materials was successfully accomplished using an efficient solvent-minimizing spray-technique. The obtained materials were studied and evaluated in regard to reaction efficiency and regioselectivity using 1D and 1H–13C correlated 2D NMR experiments. The high consistencies and temp…
We report evidence for the formation of long-lived photoproducts following excitation of iron(III) tetraphenylporphyrin chloride (Fe(III)TPPCl) in a 1:1 glass of toluene and CH(2)Cl(2) at 77 K. The formation of these photoproducts is dependent on solvent environment and temperature, appearing only in the presence of t…
Polyparylene is a polymer with outstanding properties when compared to other synthetics. Therefore, chemical vapor deposition of polyparylene is making inroads in several technical fields. Even applications demanding tight requirements on coating quality, like gate dielectrics for the semiconductor industry and semipe…
Abstract The effect of molybdenum addition on the fracture toughness and micro-hardness of Fe2B in Fe-B-C alloy was investigated. The results indicate that, with the increase in molybdenum addition, the micro-hardness of Fe2B increases and its fracture toughness first increases and then decreases. Compared with the fr…
Abstract The mass loss of the nose of projectile is an obvious phenomenon in high-speed penetration into concrete target. The mass loss percentage depends linearly on the impact velocities of projectile according to experimental data fitting results. A semi-empirical model, which can calculate the ogive-nose shape cha…
Three different Ti-based alloys with bcc structure and Laves phase were studied. The TiCr1.1V0.9, TiCr1.1V0.45Nb0.45 and TiCr1.1V0.9 + 4%Zr7Ni10 alloys were melted in arc furnace under argon atmosphere. The hydrogen absorption capacity was measured by using aparatus type Sievert's. Crystal structures, and the lattice…
The hotdog-fold enzyme 4-hydroxybenzoyl-coenzyme A (4-HB-CoA) thioesterase from Arthrobacter sp. strain AU catalyzes the hydrolysis of 4-HB-CoA to form 4-hydroxybenzoate (4-HB) and coenzyme A (CoA) in the final step of the 4-chlorobenzoate dehalogenation pathway. Guided by the published X-ray structures of the ligande…
Abstract The dense electrolyte film with the rough surfaces for solid oxide fuel cell (SOFC) was fabricated on NiO/yttria‐stabilized zirconia (YSZ) anode substrate by using dual‐sized YSZ powders without additional effort to roughen electrolyte film. The dual‐sized YSZ powders consisted of the fine YSZ powder and the…
Abstract Porous quartz ceramics were produced using river sand from the Yangtze River in China as the raw material by the use of sponge absorption methods. We found that sintering conditions clearly affected the porous structure and other properties. With increasing sintering temperature, the microstructure of the sam…
1,5-Diphenylpenta-2,4-dien-1-one (DDO) chalcone single crystals, synthesized by a base-catalysed aldol condensation reaction between cinnamaldehyde and acetophenone, have been grown by the slow evaporation of an ethanol solution. The crystals belong to the orthorhombic system with centrosymmetric space groupPbca. The…
Abstract Substantial natural aging occurring on the time scale of less than 1 month was observed in solution‐treated Mg–Gd and Mg–Tb alloys. Solution treatment at 500 and 530 °C for Mg–Gd and Mg–Tb alloys, respectively, leads to dissolution of Gd or Tb in the Mg matrix. By quenching of solution‐treated alloys to room…
Silicon oxide thin films were grown from the liquid source, polysilazane, by using mist chemical vapor deposition (CVD) at temperatures of 200–350 °C. The films were grown with a reasonable growth rate of 12 nm/min at the temperature of 200 °C, and they showed resistivity of the order of 1013 Ω·cm, although the incorp…
The technology of nitrogen jets impacting surfaces at low temperature has recently been introduced for surface cleaning/stripping. Under the impact of the jet, the material surface undergoes a thermomechanical shock inducing complex transformation mechanisms. Depending on the material and test parameters such as stand…
Abstract (Sc2O3)0.1(CeO2)0.01(ZrO2)0.89 (SCSZ) ceramic electrolyte has superior ionic conductivity in the intermediate temperature range (700–800 °C), but it does not exhibit good phase and chemical stability in comparison with 8 mol% Y2O3–ZrO2 (YSZ). To maintain high ionic conductivity and improve the stability in th…
The crystallization characteristics of CaCO 3 microparticles from supersaturate aqueous solutions in the presence of a conjugate drug-copolymer has been investigated, comparative with particles prepared in similar conditions but without polymer. The polymer conjugate, P(NVP-MA-Ox), is based on poly( N -vinylpyrrolidon…
