The energy spectrum of mobile charge carriers in a two-dimensional Antiferromagnet placed in external magnetic field is analyzed. It is shown that allowing for the magnetic sublattice skew the effective mass of mobile charge carriers in a lightly doped Antiferromagnet. This affects substantially the transport and ther…
The DC-bias superposition characteristics of NiCuZn ferrite with different amount of Bi2O3 have been investigated. The microstructure depends much on the amount of Bi2O3. The DC-bias-superposition characteristics have great relationship with the microstructure. The permeability of materials composed of tiny grains dec…
There are many bonding methods of the ceramic sintered body, such as diffusion bonding, glass bonding, and reports in this regard are not difficult to see. But the solid electrolyte zirconia ceramic bonding in NOx sensor is rarely reported. Here we use zirconia and aluminum-silicon glass together to bond zirconia cera…
The use of ceramic processes inducing a microstructural organization at the grain scale favors the improvement of strength and toughness. With layered structures, it is possible to design the microstructural characteristics of materials, leading to increased threshold strength. Layered structures can be arranged to co…
The crosslinked poly(methylmethacrylate) (PMMA) heat-sensitive nanocapsules were prepared by emulsion polymerization, in which Triton X-100 was used as an emulsifier and unsaturated hyperbranched poly(amide-ester) (UHBP) as a crosslinker. The effects of three determinative process parameters on the particle size distr…
Peptides-bearing natural amino acids scaffolds are widespread in nature and are known to exhibit a wide array of biological activities. As part of a research endeavor in investigating the synthetic utility of enantiopure azido cyclohexene silyl ether, we hereby present an approach towards the synthesis of anti-influen…
A monolayer of carbon is called graphene. It exhibits unusual properties in the Hall effect and in the cyclotron resonance. It is found that it exhibits fractional charge in the Hall effect. The interactions amongst electrons almost become constant at low temperatures. Hence, the Kohn's theorem, which shows that the i…
Nickel Phosphite Hexagonal Polyhedrons are firstly synthesized by Huan Pang, Jing Chen and co-workers on page 287. The single microcrystal Ni11(HPO3)8(OH)6 hexagonal polyhedron is successfully primarily applied as electrochemical supercapacitor electrode materials, which has a good specific capacitance, good rate capa…
Through Mechanical grounding method, CaZrO3 – 8YSZ(8% in mol yttria stabilized zirconia) electrolyte samples with different amounts of CaZrO3 at 10wt%, 20wt%, 30wt% were sintered at different temperatures in Muffle furnace. The decomposition temperature of CaZrO3 is 825°C-900°C under one atmosphere. At high temperatur…
Cover: Partial ethanolysis of unsoluble silicon-based plasma polymers into a mixture of small oligomers amenable to mass spectrometry analysis allows the architecture of the original solid network to be reconstructed. The cover images is presented by L. Charles et. al., and further details can be found on page 271.
β-SiC nanowires were successfully fabricated on pare Si (100) substrate using simple carbo-thermal evaporation of graphite at 1200°C. The obtained β-SiC nanowires were aligned with diameters ranged between 40 to 500 nm. The majority of crystal planes were β-SiC (111) with other less intensity of (200), (220) and (311)…
Methods were developed for preparing Ta 2 O 5 :Zn alloys containing less than 3 wt % Zn 2+ for the purpose of using them further in preparing lithium tantalate batches and growing from them single crystals having improved properties. A method where zinc is doped directly into a tantalum-containing back-extract followe…
ZnO heterostructures have been successfully synthesized using thermal chemical vapor deposition method. Zinc powder and oxygen were used as the starting materials, while argon gas was supplied as the carrier gas. Different types of nanostructures were deposited on layer-by-layer ZnO seeded catalyst; which its structur…
Sodium silicate solution-impregnated carbon/copper composites were prepared from electrolytic copper powder, graphite particulate and pitch coke powder through compression molding, carbonization and impregnation. The effect of different concentrations of sodium silicate solution on their mechanical and tribological pr…
Bi4-xLnxTi3O12 (Ln = La, Nd or Gd; x = 0, 0.25, 0.5, 0.75 or 1.0) fine powders were prepared by the chemical coprecipitation method. Suitable calcination temperature for each powder was determined. The effects of Ln-substitution on the sintering behaviors, crystal structures, lattice constants and microstructures of s…
Up until recently (i) c-Si and poly-crystalline Si (poly-Si have been assumed to be qualitatively different than (ii) a-Si(H). X-ray absorption and photo-emission studies combined with ab-initio many-electron theory for their interpretation have established that they are indeed much similar. In point of fact, a-Si(H)…
In this paper, the method of Poly(N-vinylcarbazole)-co-di(2-(4-methylphenyl) (MSPD) Iridium(III))(NVK-MMI) preparation was carried out. The novel polymer were based on phosphorescent polymers involving a carbazole unit and an iridium-complex unit. The structure of the polymer were characterized by elemental analyses,…
A formula is derived for calculating the maximum magnetic permeability μ mt of ferromagnets on the basis of their demagnetization factor, coercive force, saturation magnetization, and residual magnetization. The calculation results may be used in electrical engineering and magnetic structural analysis, in place of lab…

To develop novel wood preservation technique trimethylborate(TMB) and boric dioxide were used by sol-gel process to modify poplar (Populus euramevicana cv.‘I-214'.) wood. The temperature variations of the storage modulus and the loss tangent along the grain for two kinds of chemically modified poplar woods were measur…
