In this paper the kinetic changes in the phase composition of the Li2CO3–Fe2O3–ZnO system at the radiation-thermal (RT) synthesis are investigated by the methods of x-ray phase (XRD). The initial reaction mixture components were in the ratio corresponding to the stoichiometric spinel formulas: Li0.5 (1-x)ZnxFe2.5-0.5x…
Influence of 26 salts of alkali and alkaline earth metals and aluminum with different anions on change the cloud point in the system (OP-10)H2O is investigated. The influence of the nature of the cations, anions, and ionic strength was rated. The advantages of cloud point extraction for azorubin using system OP-10-H2O…
본 연구는 폴리(비닐 알코올)(PVA) 하이드로젤 안에 AgNO3 용액을 이용하여 은 나노입자(AgNPs)를 제조하였다. PVA 입자를 증류수에 용해시킨 후, 50 kGy 감마선을 조사하여 PVA 하이드로젤을 제조하였다. 감마선을 이용하여 제조된 PVA 하이드로젤을 0.01, 0.05 M 질산은 수용액에 1시간 동안 침지후, 팽윤된 하이드로젤을 꺼내 감마선을 재조사하여 PVA 하이드로젤 내부에 AgNPs를 제조하였다. AgNPs가 함유된 PVA 하이드로젤의 UV 흡수 특성 및 FE-SEM 측정 결과, 감마선 조사량이 증가할수록 AgNPs의 생성이 증가하는 것을 확인…
This article is devoted to integrated study of strength and stiffness of wall panels on a timber frame with sheeting, made of cement bonded particle boards, under the influence of positive and negative wind load. There are made the preproduction tests of load-carrying ability of metal staples used to fasten sheeting t…
As recen structura correlatio model m is a qu compara and 700 material. to higher is attribu for both a sealing Key wor
High dose Fe-ion implantation into silicon in external magnetic field results in the formation of thin silicide (Fe3S i) films with pronounced in-plane magnetic anisotropy. In this work a modified model of diffusion limited aggregation (DLA) is developed to describe the formation of ferromagnetic dendrite structure at…
It was carried out the synthesis and characterization of catalysts based on tungsten heteropolyacids (HPW)\nsupported on AlSBA-15 materials and further evaluation as catalysts in the esterification reaction of benzoic acid\nwith methanol. AlSBA-15 materials with low mineral acid (HCl) content were synthesized; ordered…
The plasma membrane is a fundamental feature of life, since it constitutes the boundary between the cell and its environment.To coordinate the various different reactions occuring there, it is highly dynamic and its constituents are organized into domains of distinct protein and lipid composition.This lateral compartm…
充满 Sm 的 skutterudites SmxCo4Sb12 (x=0.1， 0.2， 0.5 ) 经由高压力和高温度(HPHT ) 被综合技术。电的抵抗力， Seebeck 系数和热电导率的温度依赖在 300723 K 的范围在这些混合物上被测量。所有样品显示出 n 类型传导。SmxCo4Sb12 的热传导性显著地作为与空 CoSb3 相比被压抑。在结构并且实质地的虚空扰乱的 Sm 原子通过格子影响了声子繁殖，这被相信。优点的无尺寸的热电的数字， ZT，与增加温度增加了并且在 723 K 为 Sm0.5Co4Sb12 到达了 0.81 的最大的价值。
Temperatur tuang cairan logam memegang peranan penting dalam produksi benda dengan metode pengecoran. Perbedaan ketebalan benda cor akan menghasilkan karakteristik produk yang berbeda walaupun dituang pada suhu dan cetakan yang sama. Penelitian ini bertujuan untuk mengetahui pengaruh temperatur tuang dan ketebalan ben…
The paper presents the development of layered composite material, which includes a carbide substrate, a ceramic layer and a nano-scale multilayered coating. Each element of a layered tool material fulfills individual functions. The carbide layer provides raised toughness and strength of tool material, the ceramic laye…
This paper describes in detail the microstructure and phase evolution in Ti0.33Al0.67N and Ti0.50Al0.50N coatings during isothermal annealing, studied by in-situ small angle x-ray scattering (SAXS) ...
This article is devoted to the study of asphalt concrete deformations under the influence of dynamic loads, using techniques developed in close to real conditions. The paper presents the results of tests of asphalt concretes of various types with the alteration in their content large fraction crushed stone and establi…
Milling and microballs strengthening conditions influence on part’s coating surface quality experimental investigation results are provided.
This work deals with the synthesis of defined polymers with polyethylene oxide backbone. The basic monomer is glycidol and its protected derivatives. Protected glycidols such as allyl glycidyl ether, tert.butyl glycidyl ether and especially ethoxyethyl glycidyl ether give linear polymers which can me modified chemical…
Die Wechselwirkung von CO mit ultradünnen Goldfilmen auf der Re(10-10) -Oberfläche wurde mittels CO-TDS und verschiedenen LEED-Experimenten untersucht. Bei Temperaturen oberhalb von 300 K, bei denen die Goldatome ausreichend mobil sind, und bei einer Goldbedeckung unterhalb von 2 ML kommt es durch konkurrierende CO-Ad…
Renewable and biodegradable bioplastics can be produced from biopolymers such as proteins. Animal blood is a by-product from meat processing and is rich in protein. It is dried into low value bloodmeal and is used as animal feed or fertiliser. Previous work has shown that bloodmeal can be converted into a thermoplasti…
In work design procedure of factor of rigidity of an elastic element of type of the squirrel wheel» is resulted. The given technique allows to raise essentially accuracy of calculations of elastic elements applied in aviation engines.
espanolKyliniella latvica Skuja es un rodofito de amplia distribucion pero escasamente citado debido a su caracter estacional. Su presencia siempre esta ligada a ambientes bajos en nutrientes, y podria considerarse un buen indicador de oligotrofia. La especie ha sido recolectada en lagos y arroyos de America y Europa.…
