In this work we present electron beam techniques for probing the chiral structure of materials. The motivation for the work lies in two distinct aspects of chiral materials science. In the first case, chiral plasmonic excitations have recently been proposed for use in a variety of sensing technologies but require stru…
Investigation of wetting properties of ceramic reinforced metal matrixc omposites on varied roughness profiles
The dependence of physical and mechanical properties of manganese steel grade 110H13L on the effect of electrical activity during crystallization of the casting is considered. Treatment of the melt by electric current increases the speed of dissolution of metallic impurities and other components in the melt many times…
Приведены результаты оценки условий труда на рабочих местах различных участков литейных цехов с массовым характером производства, для которых разработана классификация рабочих мест по условиям труда.
The fundamental property of electrolytic systems, involved with linear combination 2âÂÂf (O) – f (H) of elemental balances: f (H) for H and f (O) for O, is presented in terms of the Generalized Approach to Electrolytic Systems (GATES). The balance 2âÂÂf (O) – f (H) is: (a) linearly dependent on charge balance (ChB…
Este trabalho analisou as diferenças entre o processo de conformação de rebites de Alumínio da liga AA 5052 e de aço inoxidável das ligas ABNT 420, ABNT 430 e ABNT 302, os quais são utilizados em grande escala na indústria cuteleira. Levando em conta as particularidades de cada material em estudo, foram analisadas as…
A composite of polyaniline and zeolite erionite were utilized to study the electrical response towards carbon monoxide in terms of effect of various ion exchange forms, vapor concentration, cyclic interval and zeolite content. Among various cation forms Na-form shows highest response because of having least electroneg…
Polymer hydrogels are a type of soft and wet materials with three-dimensional network structure, large water content and hydrophilicity. It plays a very important effect in the human tissue engineering because it has some excellent characteristics as human active tissue. In this study, physical/chemical hybrid cross-l…
金や銀などの金属を数十ナノメートル程度のナノ粒子にするとそのサイズや形状を反映して多様で鮮やかな発色を示す。この発色現象の起源は金属の伝導電子の集団振動と光との共鳴でありプラズモン共鳴と呼ばれる。プラズモン共鳴の結果，金属ナノ粒子表面は強い局在光で被われる。この局在光と金属ナノ粒子表面の分子が相互作用することで分子の光学応答が極端に増強される。この増強現象を利用した分光をプラズモン増強分光と呼ぶ。本解説ではプラズモン増強分光の増強メカニズムについてプラズモン増強分光の一種である表面増強ラマン散乱分光を用いて解説する。そして表面増強ラマン散乱分光を1分子の構造変化の観察に応用した例を報告する。また，プラズモン増強分光にナノ粒子の代わ…
With the rapid development of science and technology, the unceasing enhancement of component integration degree, and the increasingly demanding of parts using conditions, the part that the traditional metal materials and alloy materials preparation is hard to meet the requirements of the use of some special conditions…

Molecular spintronics aims to store and transmit information encoded in the electron spin using single molecular based magnetic units. In this thesis the magnetic properties of hybrid molecular-metallic interfaces are investigated by ab initio density functional theory, the most successful electronic structure method…
Microporous metal imidazolates [M(Im)2] have drawn intense attention in recent years as a wide variety of metal coordination polymers which can be functionally applied for separation technology. Due to the strong metal-nitrogen bonds between the metal centers and organic imidazolate ligands, their chemical stability i…

Предложен способ формирования импульсов тока пучка с длительностью до 100 нс с короткими (порядка 5 нс) фронтами в плазменном источнике электронов. Для реализации способа предлагается использовать плазменный источник электронов на основе разряда в скрещенных E×H полях с управляющим электродом, который не участвует в ф…
Mechanochemistry is increasingly used for synthesizing soft matter materials including metal organic compounds and cocrystals. The ever-increasing interest in this method is contrasted by a limited mechanistic understanding of the mechanochemical reactivity and selectivity. Time-resolved in situ investigations of mill…
This study, encouraging the use of PLA membranes for actinomycetes cultivations, could unveil functional insights associated with antibiotic production and S. coelicolor cellimmobilization
Am DESY (Deutsches Elektronen Synchrotron), Standort Zeuthen wird ein linearer Elek-tronenbeschleuniger betrieben. Dabei werden Komponenten, welche sich im Beschleuniger-raum befinden aktiviert. Wenn solche Komponenten den Beschleunigerraum verlassen sollen,müssen sie zuerst das Freigabeverfahren durchlaufen. Die Frei…
The copper tin sulfide Cu2SnS3 (CTS) is a p-type direct band gap material; its elements are non-toxic and earth-abundant. It can be used in photo thermal conversion of solar energy and as selective radiation filters on architectural windows. The CTS compound was synthesized by solid state reaction method. The influenc…
In this thesis, covalently bonded nanostructures are constructed bottom-up on well-defined interfaces. Through on-surface synthesis, functional molecules, such as porphines, are successfully fused to graphene edges and graphene nanoribbons on Ag(111) with atomic precision. Non-contact atomic force microscopy is exploi…
