We address RuO2 nanoparticles as an appealing link between single-crystal model and real (supported) catalysts. From a first-principles based Wulff construction under explicit consideration of a CO oxidation reactive environment we deduce a prominent role of hitherto little studied, apical RuO2(111) facets for the lon…
Male and female Scylla serrata juvenile crabs were stocked separately in cement ponds (14 x 8 x 0.8 m; 90 m3) and reared for 90 days. The study was conducted at the Fisheries Research Station, JAU. Okha, Gujarat. The crabs were fed trash fish and Trochus spp.\nThe survival rates of male and female crabs were higher in…
In recent year, natural fiber becomes an environmental advantage due to the environmental alertness.The goal of current study was to investigate the mechanical behavior of hybrid jute/flax epoxy composite based on the tensile properties.The jute twill and flax plain weave were laminated to produce a range of ligt weig…
Li0.5Bi0.5TiO3 ceramic powder was synthesized by high energy ball milling. The X-ray diffraction pattern of the sample was analyzed in a quantitative manner using rietveld analysis. X-rays is the finger print of a material and the diffracted intensity can be used to dig out a lot of information related to the material…
Titanate nanotubes were synthesized under hydrothermal conditions from TiO2 powder, followed by HCl rinsing. The properties of prepared nanotubes were investigated in detail by various analytic techniques such as field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transformed infra-re…
The current research focuses on peroxide ion incorporation in the structure of strontium \nhydroxyapatite (SrHAp) by exposure to H2O2 in a closed hydrothermal vessel under mild conditions \nat 130 to 170 oC. Peroxide enriched strontium apatite (SrPerAp) was characterized for structure by \nX-Ray diffraction, for perox…
・コンピュータ能力の急速な進歩により，水に溶けた蛋白質の動く様子をシミュレーションできるようになり，2013年のノーベル化学賞は分子動力学に贈られた．これまで経験に頼ってきた薬の開発が，理論的な設計により大きく変わろうとしている．ところが，シミュレーションをするには3A 以下の原子レベルの結晶構造の情報が必須である．標的となる蛋白質の結晶ができなかったり，結晶化できても解像度の悪いことが薬設計のボトルネックとなっている．・この問題に応える技術が開発された．『Science』の2015 年6 月5 号にNIH のSubramaniam らが，クライオ電顕での多数のイメージの解析から，2.2A の解像度でβガラクトシダーゼと阻害剤の結…
The radiative degradation curve of carmellose sodium (CMC sodium) in aqueous solution has been reported. Both densities and viscosities of aqueous (CMC sodium) in moderate concentrations irradiate. Gamma irradiation of (CMC sodium) decreased the value of density, specific viscosities molar mass and hydrodynamic volume…
In this paper, the low-frequency nonlinear oscillations and energy localizations of Single-Walled Carbon Nanotubes (SWNTs) are analysed. The SWNTs dynamics is studied within the framework of the Sanders-Koiter thin shell theory. The circumferential flexure vibration modes (CFMs) are considered. Simply supported bounda…
A novel gasification concept combining entrained flow gasification of coal and Solid Oxide Fuel Cells (SOFC) has been developed, simulated and evaluated in Aspen Plus®.The main characteristic of the concept is a recirculation of anode exhaust from the SOFC to the gasifier in order to substitute transport gas and gasif…
Cadmium Telluride (CdTe) is one of the promising photovoltaic materials for solar cell. The post deposition treatment is important to improve the structural, electrical and optical properties of the CdTe thin films. Hence comparative study between the thermal annealing and laser annealing was carried out is this study…
Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Lobar Degeneration (FTLD) are two devastating adult onset neurodegenerative disorders. In ALS patients FUS mutations were found as a primary cause. For FTLD-TDP, TMEM106B was identified to be a risk factor. To gain more insight into the pathomechanisms, mouse mode…
Вивчено вплив домішок цетилтриметиламоній-монтморилонiту та нанооксиду титану на довговічність інтумесцентного покриття для металевих будівельних конструкцій. Встановлено, що додавання в інту-месцентну систему нанодисперсних речовин подовжує термін експлуатації покриття на три роки. При цьому більш ефективним для вогн…
This report refers to complementary material testing to support the design and production of UHPC floaters for installation in the Wave Star Machine under FLOAT2 project. The main objective of WP4 is the characterization of mechanical properties of fiber-reinforced UHPC.
Sequential substituted Schiff bases were prepared by direct condensation of urea and benzaldehyde or its substituents (o, m and p-bromo and hydroxy ) as ( 1 : 2 ) mole ratio ( urea : benzaldehyde or its substituents ) , The prepared compounds characterized by infrared spectroscopy FT-IR and Thin layer chromatography T…
采用异步轧制的工艺,使Fe-30Mn-3Si-3Al的TWIP钢获得2种厚度(0.5mm和1mm)1μm左右的超细晶组织样品.经过不同温度退火后进行力学性能和微观组织的测试.通过EBSD对试样拉伸前后的组织进行了分析,拉伸前基体UFG晶粒和部分再结晶晶粒呈层片状交替分布,拉伸后再结晶晶粒被显著拉长.软(部分再结晶晶粒)硬(UFG晶粒)相是造成强度和塑性优良匹配的主要原因.
The Bloch bands in many crystals have a degenerate set of energy extrema in momentum space known as valleys. For band-edge carriers, the valley index becomes a discrete degree of freedom in addition to spin. In this talk, I will show that in monolayer transition metal dichalcogenides, the pair of valleys which are tim…
