Optical properties of nanoparticles are related to their surface plasmon resonance. In this work, we use Mie theory to compute the extinction, absorption, and scattering properties of noble metal nanoparticles. The calculated results agree well with the experimental values. With increasing particle size, particle dipo…
Crystal structure determinations based on X-ray powder diffraction data were performed for three ternary silicides in the Dy-Ni-Si system. The structures of DyNiSi 3 , Dy 3 Ni 6 Si 2 , and DyNiSi belong to the structure types SmNiGe 3 (Pearson symbol oS20, space group Cmmm, a = 3.9225(3), b = 20.955(1), c = 3.9465(3)…
This work analyzes and summarizes the results of an investigation of ternary phase diagrams of magnesium with two rare-earth metals of different subgroups, conducted in IMET RAS in connection with the development of high-temperature magnesium alloys. During this investigation a number of regularities in the constituti…
Mixed ligand complexes of bivalent metal ions, viz; M= Fe(II),Co(II),Ni(II),Cu(II), Zn(II), Cd (II), and Hg(II) of the composition Na2[M (Amox)(Sac)3] in 1:1:3 molar ratio, (where Amox = Amoxicillin tryhydrate (C16H19N3O5S.H2O) and Sac = Saccharine(C7H5NO3S) have been synthesized and characterized by repeated melting…
In view of increasing exploitation of clays for the ceramic industry and for the purpose of the value addition of the national natural resource, a study was conducted to characterize the Miocene clay occurring in the Sillon South Rif area of Morocco through geochemical, mineralogical, submicroscopic (scanning electron…
Recently, investigations have been made into the inhibition properties of natural plants so as to find alternatives to synthetic inhibitors. In order to contribute the contemporary interests, the inhibition action of Brassica oleracea capitata extract on mild Steel and Zinc corrosion in 2.0M H 2 S0 4 solution was stud…
Alternative micro-sized LiNi₀.₅Mn₁.₅O₄ spinels with octahedral structure (showing only one type of {111} crystal face) or chamfered polyhedral structure with extra other faces have been synthesized via a controllable method. A possible growth model, complexing–pyrolyzing-oriented, is also proposed for the formation of…
Chitosan (Chi) is an extremely promising natural biopolymer with remarkable potency for the development of drug and vaccine delivery nanosystems. Various Chi derivatives are used to form nanoparticles (NPs) with unique properties. However, the efficacy of the therapy delivered by Chi NPs depends significantly on NP bi…
Quantum dot sensitized solar cells (QDSCs) have attracted considerable attention recently and become promising candidates for realizing a cost-effective solar cell. The design and synthesis of quantum dots (QDs) for achieving high photoelectric performance is an urgent need imposed on scientists. Here, we have succeed…
This volume presents the majority of topics in synchrotron science that are of use to the clay science community. The chapters presented in this volume serve not only as significant statements on the state of these applications, but also as useful primers to potential new users of synchrotron facilities.
The use of polyester fabrics in automotive upholstery has created a need for disperse dyes of exceptionally high sublimation and light fastness to withstand extended exposure to light and heat. Thus, in an attempt to find new disperse dyes of high fastness to sublimation and light, we report here the synthesis and eva…
Изучение золотистых водорослей, впервые проведенное в прудах Ботанического института им. В.Л. Комарова (БИН) РАН на протяжении 8 мес с применением методов световой и электронной микроскопии, позволило выявить разнообразный видовой состав золотистых водорослей (42 вида и внутривидовых таксона), а также проследить сезон…
Atomic layer deposition of Fe₂O₃ is generally performed at temperatures above 350 °C. In this work, Fe₂O₃ thin films were deposited by remote plasma enhanced atomic layer deposition using tertiary butyl ferrocene (TBF) and O₂ plasma in a broad temperature range starting from 150 to 400 °C. A maximum growth rate of 1.2…
Thermal decomposition in nitrogen atmosphere and thermal oxidation decomposition in air atmosphere of calcium stearate were investigated by TGA and DSC.The decomposition products were characterized by FTIR.The thermal oxidation decomposition mechanism was discussed.The thermal decomposition of calcium stearate include…
This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics were selected. Suitable suspension amounts, the clay addition and sintering temperature were de…
In this paper a new method which measures fiber orientation in CFRP laminates from X-ray CT images is proposed. In the proposed method, fiber orientation is analyzed by applying digital image correlation method (DIC) to the acquired tomographic images. By using DIC, brightness pattern, which results from radiodensity…
In order to develop an energy-saving insoluble anode for Zn electrowinning, Pb-based anodes in which catalyst powders of low oxygen evolution overpotential were spread over the Pb substrate were prepared by powder-rolling method and the effect of the catalyst powder on lowering the anode potential was investigated. It…
To develop propranolol hydrochloride(PRO) liposomal gel for the treatment of infantile hemangioma(IH) and to evaluate its permeation on transdermal delivery in vitro PRO liposomal gel was prepared with the traditional film dispersion method using cholesterol,phosphatidyl ethanolamine and the drug.Its morphology was in…
Optical nanocavities (racetrack resonators and photonic crystal cavities) are fabricated in bulk single-crystal diamond via angled-etching. Devices operating in the telecom band exhibited Q-factors exceeding 105, while devices in the visible yielded Q-factors approaching 104.
We have successfully grown the single crystal of Y3Ru4Ge13 which crystallizes in the cubic crystal structure with the space group Pm3n. Y3Ru4Ge13 exhibits superconductivity below 2.85K as determined using electrical resistivity, magnetic susceptibility and heat capacity measurements. Hall Effect measurements show that…
