This study reports the results of kinetic of hydrogen generation from the catalytic hydrolysis of sodium borohydride. Iridium(0) particles catalyst was stabilized by diethylene glycol. Catalyst iridium was characterized by field emission scanning electron microscopy and energy dispersive X-ray spectroscopy. Hydrolysis…
植物油脂を基盤とするバイオプラスチックの研究動向を紹介する。大豆油や亜麻仁油のエポキシ化物を酸無水物と硬化させることで高性能ネットワークポリマーが創製された。また，エポキシ化植物油脂の硬化物をセルロース等のバイオフィラーと複合化することにより，油脂ポリマーの物性が向上した。ナイロンのモノマー合成に用いられるヒマシ油を原料とするポリウレタンフォーム用のポリオールが開発された。ヒマシ油を開始剤とする乳酸あるいはラクチドの重合により得られる分岐状ポリ乳酸はバイオプラスチック用の可塑剤や結晶核剤として作用する。
Heat-resistant domain-refined grain-oriented electrical steel sheet is produced by applying domain-refining technology using linear grooves. We investigated the domain structure of grain-oriented silicon steel sheet with grooves formed on one side by electrolytic etching method. The domain structures on the grooved si…

Band theoretical results within the density functional theory are reported for the uranates K2UO4 and Na4UO5. The two structures are differentiated respectively by uranyl and reverse uranyl-type short U-O distances characterizing the UO6 octahedra, as also reflected by larger compressibility and stability of the potas…

In this research we study the effect of different extracts of Teucrium polium (cold water, hot water and alcohol extraction), effect of silver nanoparticles and the combination effect of Teucrium polium extracts with silver nanoparticles against different pathogenic microorganisms Escherichia coli, Pseudomonas aerugin…
We have investigated the local structure and spontaneous polarization (P s ) of Ba 1-x Ca x TiO 3 (BCT) by density functional theory (DFT) calculations. The DFT calculations based on a supercell approach show that Ca atoms are markedly displaced cooperatively with the adjacent Ti atoms along the P s direction. It is s…
In this paper using Density Functional Theory (DFT), the principal carbonallo tropic crystalline structures (Diamond, graphite, nanotube y fullerene-C60) were simulated. The results shows diamond sp3 bonds formation between carbon atomsand low reactivity, indicating low probability of lateral compound formation and hi…
In this study, catalytic alumina porous medium has been fabricated by using platinum as an active material for micro-combustion application. Platinum has been deposited onto porous medium surface via wet impregnation method. The porous medium undergoes surface modification process via wash coating method using gamma a…
The widespread use and application of in-plane switching liquid crystal displays (IPS-LCDs) is limited by their slow response. In this letter, a fast-response IPS-LCD with a protrusion structure is proposed. The gray-to-gray response time of the IPS-LCD is reduced by 20% to 30%. The difference in cell gap induced by t…
nano-SiO2 modified core-shell polyacrylate composite emulsion was synthesized by seeded semi-continuous starved pre-emulsion polymerization and sol-gel technique. The influence of 3-methacryloxypropyltrimethoxysilane(KH-570), tetraethoxysilane(TEOS) on the properties of emulsion and film were studied. The SiO2/silicon…
Ni2MnGa thin films raise great interest due to their properties, which provide them with strong potential for technological applications. Ni2MnGa thin films were prepared by r.f. sputtering deposition on Si substrates at low temperature (400 ºC). Film thicknesses in the range 10-120 nm were obtained. A study of the st…
The research is devoted to characterization of polycarbonate (PC)/acrylonitrile-butadiene styrene (ABS) blend nanocomposites in respects to it mechanical and calorimetric properties. It is shown that PC blend with 10wt% of ABS is more suitable for development of polymer-clay nanocomposites than PC blend with 40wt.% of…
Detection of hydrogen peroxide by using fluorescence resonance energy transfer from InGaN quantum wells to Au nanoclusters via optical waveguiding has been demonstrated. This technique provides a new strategy for the visual detection of H 2 O 2 with large-area analysis.
ZnS QDs were synthesized via aqueous method and growth process of crystals were kinetically studied. PL Results revealed that the growth kinetic involves two steps in which Oriented Attachment and Ostwald Ripening are dominated mechanism.
Kinetic analysis is one of the most important applications in thermal analysis study. In this work, the kinetic analysis of poultry processing dewatered sludge (PPDS) was conducted by using a Thermogravimetric Analysis (TGA) instrument. The kinetic parameters such as activation energy (Ea) and correlation coefficient…
During the oil and gas wells exploitation and transportation, carbon dioxide corrosion is one of main reasons for the corrosion of metallic materials. So the methods of preventing and reducing carbon dioxide corrosion have become a widely focused problem. The foreign and domestic practices and experiences show that as…
In this work, undoped and Ag-doped ZnS quantum dots were synthesized using various chemical methods. The products were characterized using X-ray diffraction (XRD), UV-visible spectroscopy and Photoluminescence spectroscopy. Our results revealed that the size of the as-prepared samples range from 1–6 nm in diameter and…
