In this paper we apply the general theory of exact relations to derive all microstructure-independent relations for effective conductivity of fiber-reinforced composites with the Hall effect. We also derive all possible links between effective conductivities of two composites that have the same microstructure but are…
The racemic C2-symmetric dialcohol endo-4,endo-8-dimethylbicyclo[3.3.1]nonane-endo-2,endo-6-diol 2 yields isostructural inclusion compounds in cubic space group Ia from nearly all recrystallisation experiments, but it has a different apohost structure. The X-ray structures of the alternative inclusion crystal forms, (…
This paper describes the results obtained on the corrosion fatigue behavior of Type 316LN (UNS S31653) stainless steel base metal in boiling acidified sodium chloride (NaCl) solution, and of Type 316LN stainless steel base metal and Type 316N stainless steel weld metal obtained in boiling 45% magnesium chloride (MgCl2…
Abstract—Use of water with different molecular mobilities could affect drug dissolution of a dosage form and such profile of water might be modifiable using microwave. This study investigated the effects of microwave on water and its influences on dissolution of free drugs and drugs in calcium-crosslinked alginate bea…
Solid oxide fuel cells (SOFCs) are high temperature fuel cells with a strong potential for stationary power house applications. However, considerable challenges are to be overcome to connect these cells to the power grid. The cells have to satisfy the changing demand of the grid without sacrificing their efficiencies…
In aqueous acetate buffer media, hydrogen peroxide reduces the bridging superoxide in [(NH3)5CoIII(micro-O2)CoIII(NH3)5]5+ (1) to the corresponding peroxide in the complex, [(NH3)5CoIII(micro-O2H)CoIII(NH2)(NH3)4]4+ (2), itself being oxidized to HO2*. The complex 2 thus produced decomposes rapidly to the final product…
Concrete is the most used material in construction worldwide. Concrete is a composite material including three phases: cement paste, aggregate and interfacial transition zone (ITZ). Previous research has demonstrated that the macro behaviour of concrete represents the integration of its constituent phases. Here, we pr…
Abstract The interaction of water-soluble polymer conjugates of the anticancer agent paclitaxel and albumin as model protein has been investigated using fluorescence spectroscopy and NMR. Drugs and drug conjugates can enter the hydrophobic core of albumin; the kinetics of the interaction with the fluorophore, however,…
A organic nonlinear optical material, L-alanine maleate (LALM) was synthesized. Bulk Single crystals of LALM have been grown by slow cooling method with a solution pH of 5. The solubility of L-alanine maleate has been deter-mined for various temperatures. Large size sin-gle crystal of 2.0 x 1.2 x 0.8 cm3 has been grow…
ABSTRACT. We introduce the class H(α, β) of analytic functions with negative coefficients. In this paper we give some properties of functions in the class H(α, β) and we obtain coefficient estimates, neighborhood and integral means inequalities for the function f(z) belonging to the class H(α, β). We also establish so…
Fulgimides monosubstituted with [M(bpy)(3)](2+) (M = Ru, Os; bpy = 2,2'-bipyridine) chromophore units and with a single bpy group were synthesized and investigated as components of conceivable dinuclear photochromic switches of luminescence. The E-, Z- and closed-ring (C) photoisomer forms of the bpy-bound fulgimide w…
An optically active pi-conjugated poly(azomethine) can be self-assembled into nanometer-sized fibrous architectures with a unique optical activity in the film state, whereas its corresponding racemic analogue did not show any distinct self-assembling properties.
Purpose: Investigation of the Ni-YSZ cermets for anode supported solid oxide fuel cells (SOFC) prepared by extrusion or powder injection moulding process, sintered and reduced of NiO-YSZ. Design/methodology/approach: Density examination, shrinkage examination, transverse rupture strength tests, microstructure examinat…
Chemically modified styrene butadiene rubber (SBR) with nitro and chloro functionalities are prepared by the nitromercuration reaction of SBR through a phase transfer catalyst.Activation energy for this chemical reaction calculated from the time temperature data on the chemical reaction by the measurement of percentag…
The crystal structure of (Per)2[Co(mnt)2], was investigated by single crystal X-ray diffraction. Its refinement shows a strong chemical dimerization of the anions [Co(mnt)2]22−. This is responsible for a unit cell doubling along the staking axis b when compared with other members of the α-(Per)2[M(mnt)2] family of the…
The steam reformer for hydrogen production from methane is studied by a numerical method. Langmuir-Hinshelwood model is incorporated for catalytic surface reactions, and the pseudo-homogeneous model is used to take into account local equilibrium phenomena between a catalyst and bulk gas. Dominant chemical reactions ar…
The surface layer of soil consisting of the mixture of mineral and organic matter reflects the nature and properties of the soil. Weathering the minerals of the earth crust originally derived most of the substances including plant nutrients. Among various substances, clay is an important soil constituent that controls…
A modular design approach has been utilized to develop molecular 'pockets' featuring three integrated components, namely a phosphorescent Pt(II)-pi(organic) moiety, a suitable receptor group, and a rigid, conjugated connecting backbone, and the cavities therein are examined by NMR spectroscopy and an X-ray crystal str…
The current status of research and development of an electrodynamic tether (EDT) system for space debris mitigation is described. EDT is a kind of advanced propulsion technologies, which requires no propellant and electric power in theory. Since debris de-orbit systems need highly efficient propulsion systems, EDT can…
Newly developed conjugated terthiophene surfactants are able to aggregate in water and to act as a host for hydrophobic chromophores, creating a multiple donor-acceptor energy transfer (ET) system by self-assembly.
