xDy2O3-Bi0.5(Na0.82K0.18)0.5TiO3(0-0.4wt%) ceramics were synthesized by conventional solid-state processes. X-ray diffraction pattern confirmed that the tetragonal and rhombohedral phases co-existed in the Dy2O3 doped Bi0.5(Na0.82K0.18)0.5TiO3 ceramics from x = 0.05 to 0.4 wt% Dy2O3. SEM images indicate that doping of…
Ferroelectric domain structure and evolution, as well as phase transition, of [001]-oriented 34Pb(In1/2Nb1/2)O3–0.25Pb(Mg1/3Nb2/3)O3–0.41PbTiO3 single crystal has been studied through temperature and frequency-dependent relative permittivity characterization. Under dc bias, the transition temperature from rhombohedral…
Using the full-potential linearized augmented plane wave method within the generalized gradient approximation, we investigatete the electronic structures, magnetisms and half-metallicities of the full-Heusler X2YGa (X=Co, Fe, Ni; Y=V, Cr, Mn) alloys. It is found that the spin-orbit coupling has little effect on the el…
Relation between impact and mechanical properties and morphology of polypropylene (PP)/elastomer/filler ternary composite was investigated. Polystyrene-block-poly(ethylene-butene)-block-polystyrene triblock copolymer (SEBS) or carboxylated SEBS (C-SEBS) was used as elastomer and calcium carbonate (CaCO3) having mean s…
Investigations on the dynamic absorption processes of double-layered knitted fabrics enabled to anticipate the fabric’s ability to absorb humidity, transmit it to the next layer and evaporate to the environment, as well as to find the best combination of raw materials and knitting structure of fabrics designed for clo…
We determine experimentally the spin structure of half-metallic Co2FeAl0.4Si0.6 Heusler alloy elements using magnetic microscopy. Following magnetic saturation, the dominant magnetic states consist of quasi-uniform configurations, where a strong influence from the magnetocrystalline anisotropy is visible. Heating expe…

The effect of a series of mono-and bis-azo dyes derived from dihydroxynaphthalene on the dissolution of aluminum in 2 M HCl solutions was studied using weight loss, thermometry and galvanostatic polarization techniques. The inhibition efficiency was found to increase with increasing concentration of inhibitor to reach…
In the present work, graft copolymerization of polyacrylonitrile onto chitosan has been carried out in the presence of ceric ammonium nitrate redox initiator. Chitosan has been used as an adsorbent for the removal of heavy metal ions from aqueous solution through adsorption process. The property of chitosan is enhance…
Bambo particles as a waste byproduct from bamboo processing industry are suggested to be a promising material for binderless particleboard. The quality of binderless particleboard is affected by several factors, such as pretreatment, pressing method, pressing condition, moisture content, and particle size. This study…
Materials made of carbon that can be synthesised and characterised at the nano level have become a mainstay in the nanotechnology arena. These carbon materials can have a remarkable range of morphologies. They can have structures that are either hollow or filled and can take many shapes, as evidenced by the well-docum…
The aim of this paper is to show, using a comparative analysis, all the differences, as well as existing advantages and disadvantages of two different sizing procedures. Materials used in the implementation of this extensive research are ring-spun cotton yarns, sized with PVA size. Tested parameters of yarn were analy…
In this paper, a family of novel Gemini surfactants from mono alkyl glycerol ether with different hydrophobe lengths (C12, C18) and different spacers as ethylene glycol, hydroquinol, N,N,N\,N\, tetramethylene diamine and sodium-bis-N,N(carboxymethyl) ethylene diamine were synthesized on a laboratory scale. The compoun…
Zinc Selenide nanoparticles were synthesized by a microwave irradiation technique at 2.8 GHz using 7N purity Zn and Se powder in stoichiometric ratio as the starting materials. The crystal system and phase was confirmed by powder X-ray diffraction, the crystallite size was calculated using Scherer’s formula and found…
Electromagnetic wave absorbers(EMWAs)(i.e.microwave wave absorbers) are important materials for military equipment.Ideal EMWA should exhibit thin matching thickness,low density,broad bandwidth,and strong EM absorption.The recent advances of EMWA were reviewed in this study,and the shortcomings in current studies and a…
Water soluble conducting polymer composite poly(vinyl alcohol-threonine) (PVAT) was chemically synthesized and characterized by FTIR, LCZ and SEM-EDX analysis. The corrosion inhibition performance was evaluated for mild steel corrosion in 1M HCl at various concentrations, and the results were compared with that of the…

酵素糖化処理後のスギ残渣の化学組成分析を行うとともに25℃での水蒸気吸脱着等温線を測定し，吸放湿特性を検討した。さらに，糖化残渣を原料に熱圧プレスによるモールド成型またはポリプロピレン（PP）との混練を行ったのちに射出成型するとともに，得られたそれぞれの成型物について水分特性や寸法安定性，強度特性を評価した。熱水洗浄した糖化残渣は，糖化前のスギ木粉（コントロール）と比べホロセルロースの比率が半分にまで減少した場合でも，相対湿度60％以上の高湿度域で高い吸湿性を示した。しかしながら，同じ糖化残渣を用いたモールド成型物では吸湿性の低下が認められるとともに厚さ膨潤がスギよりも大きく低下した。一方，試料とPPを同じ比率で混練したのち射出成…
To obtain ideal Goss-oriented Fe-3.1%Si electrical steel, we studied the Goss orientation and microstructure during the various processes from hot-band annealing to the primary recrystallization. In particular, we examined the effect of the heating rate (20°C/s and 150°C/s) on the primary recrystallization behavior. I…
Nanocrystalline powders showed the distinguishable difference in catalytic, electrical and optical properties from macroscopic, microscopic and bulk materials. Among them, zinc oxide (ZnO) is one of the candidates that have been attracting attention because of its wide band gap energy of about 3.37 eV. In this work, Z…
