Three methods of an area detector type multiaxial stress measurement were studied in this paper. The first method, which was proposed by Sasaki and Hirose, gives us correct results when precise diffraction data are obtained and are used in the stress calculation. The error of the stress determination sometimes occurs…
We prepared phthalate derivatives based flexible electrochromic (EC) cell with gel electrolyte containing DMSO solvent in order to improve memory properties. The cell showed vivid color change from water transparent to three primary colors by electrochemical reduction as similar to the liquid electrolyte cell reported…
The photoluminescence properties of silicon-based xenotime-type rare-earth phosphate as an orange-red-emitting phosphor material, SrY 3 SiP 5 O 20 :xEu 3+ ͑0.2, 0.6, 1, 2, 3, 5, 10, and 15 mol %͒, are reported.The photoluminescence spectra of the silicon phosphate indicated the simultaneous occurrence of six predomina…
The static water absorption, fabric thickness and surface density of woven structures were investigated. Samples were woven for this experiment using low, medium and high pile of 6, 9, and 12 mm, respectively The fabrics were affected by various impacts/finishing like macerating, washing with detergent, washing with d…
Symmetrical four‐chained (tetracatenar) and six‐chained (hexacatenar) bi‐1,3,4‐oxadiazole ester derivatives, namely 5,5′‐bis[phenyl(3,4‐dialkoxybenzoate)]‐2,2′‐bi‐1,3,4‐oxadiazole (Cn, n = 6, 10, 12, 14, 16) and 5,5′‐bis[phenyl(3,4,5‐trialkoxybenzoate)]‐2,2′‐bi‐1,3,4‐oxadiazole (Dn, n = 7, 10, 14, 16) were synthesised…
Shape memory alloy (SMA) actuators have found a wide range of applications due to their unique properties such as high force, long stroke, small size, light weight, and silent operation, etc. However, their strong nonlinear properties make them a challenge to achieve accurate actuations. A simple control strategy is p…
Atmospheric corrosion rate of Al, Zn and mild steel (MS) as well as salinity and sulphation rate have been determined under outdoor exposure at Tithal (Dist. Valsad) situated in South Gujarat, India. MS samples exposed vertically suffer less corrosion than those exposed at an angle of 45°. Monthly corrosion rate was i…
Structure and configuration of boundary dislocations on various low angle tilt grain boundaries in alumina were considered based on the ideas that the boundary is composed of regularly arrayed edge dislocations and that the dislocations could dissociate into partial dislocations with maintaining the hcp-like oxygen su…
The diversity and fertility of 15 soils in the Doi Inthanon area of Chiang Mai province was studied using standard methods for field investigation and laboratory analysis, to characterize differences in their morphology, their physical and chemical properties and to assess their fertility levels. The soils occupied ar…
Problem statement: Nano-scale porous ZnO with high surface area have been studied to enhance physicochemical and electrochemical properties of certain optoelectronic devices applications. Approach: ZnO porous structure consists of flake-shape particles was synthesized through pyrolitic reaction of hydrozincite as Chem…
The CaCO3/biopolymer composite materials have been prepared by a two-step synthesis. The biopolymer was synthesized from chitosan and acrylic acid in supercritical carbon dioxide, then a large scale of novel flowerlike structured calcite CaCO3 on the biopolymer has been synthesized for the first time by the following…
Ultrathin carbon films with a monolayer of uniform mesopores were synthesized on a silicon substrate by contacting triblock copolymer films with benzyl alcohol vapor followed by carbonization.
We report on a tetranuclear Mn(ii) complex possessing a F-bridged molecular square topology directed by 1,10-phenanthroline ligands.
By adding a small amount of HMPA approximately 2.5 equivalent or ca. 8.1 wt% H2 can be released from the LiAlH4–LiNH2 mixture at ambient temperature, which is ∼370 °C lower than the corresponding solid-state dehydrogenation. NMR characterizations reveal the formation of intermediates, such as [AlH] and [AlN] species,…
We prepared an iron(II) spin crossover complex with a new ligand, [1,2,5]thiadiazolo[3,4-f][1,10]phenanthroline, which is a 1,10-phenanthroline analogue annulated with a thiadiazole moiety. X-Ray crystal analysis indicated a 3D network structure formed by short S⋯S contacts, and magnetic measurements revealed a broad…
For successful mesh hernia treatment with medical meshes, it is important to induce angiogenesis and fibroplasia around the site of the mesh implanted. The objective of this study is to combine a mesh with a gelatin hydrogel for basic fibroblast growth factor (bFGF) release and evaluate the angiogenic activity in vivo…
Ti(70)Zr(10)Co(20) containing an icosahedral quasicrystalline phase has been fabricated, and presents high activity and selectivity in catalyzing the oxidation of cyclohexane with oxygen under solvent-free conditions.
Acetate-induced demetalation of a {gamma-SiW(10)Fe(2)}-based dimer affords an acetato/hydroxo-bridged triiron cluster stabilized by two isomerically distinct Keggin units.
Matrix isolation IR spectroscopy has been used to study the vacuum pyrolysis of 1,1,3,3-tetramethyldisiloxane (L1), 1,1,3,3,5,5-hexamethyltrisiloxane (L2) and 3H,5H-octamethyltetrasiloxane (L3) at ca. 1000 K in a flow reactor at low pressures. The hydrocarbons CH3, CH4, C2H2, C2H4, and C2H6 were observed as prominent…
This work analyses the nature of temporal patterning of the anodic potential induced by chlorides during polarization of iron under current-controlled conditions in acid solutions. It is shown that potential oscillations emerged as a result of the local chloride attack of a thin oxide layer, which covers the iron surf…
