In response to an increasing global need for inexpensive, energy efficient electronics, the field of organic semiconductors has experienced tremendous growth over the last 3 decades. In addition to their low cost, and interesting electronic and optical properties, organic semiconductors offer the additional benfits of…
To synthesize silicate modified hydrotalcite written as Mg-Al-SiO3, series synthesis methods such as co-precipitation, roasting recovery and ion exchange were tested using Mg(NO3)2·6H2O, Al(NO3)3·9H2O and Na2SiO3·9H2O as raw materials.With crystallinity and purity of product as judgment standard, co-precipitation hydr…
This study is an inquiry into the impact of the Soviet-Polish War (1919-1921) on the course of revolutionary government during the Civil War period as a “formative experience.” Through the war, the Bolshevik leaders made a first attempt to export the socialist revolution to Poland and other countries on the principle…
Increasing energy demand, faster depletion of fossil fuels and adverse impacts to environment lead to search for renewable energy sources. Solar energy is one the most promising alternatives to replace fossil fuels. Sophisticated fabrication procedures and costly raw materials of crystalline silicon (c-Si) solar cells…
A grand challenge in materials science is to create materials with complex, rationally designed structures and functionalities. Self-assembly is a promising route to fabricate these materials with nano-scale precision, and efficiency in terms of cost and time. Nanocomposites comprised of block copolymer (BCP)-based su…
Background: From the experiment we discovered that the hydroxyapatite can be synthesis by the crystallization process on hydroxyethylene sponges. The sponges of hydroxyethylene was fabricated successfully. The liquid placed in the freeze dryer for the sponges formation. The sponges let the samples to have larger surfa…
Im Rahmen dieser Arbeit wurde nachgewiesen, dass die von Charnell (1971) veröffentlichten Kristallgrößen der Na-Faujasit (Zeolith X) von 140 µm erreicht werden konnten. Es wurde ersichtlich, dass die Kristallgrößen mit steigendem Triethanolamin (TEA)-Verhältnis zugenommen haben und sich im Gegenzug die Größe der Eleme…
Осуществлен эффективный электросинтез наночастиц палладия(0) в растворе медиаторным электрохимическим восстановлением комплексного дианиона [PdCl4]2 в среде ДМСО/0.1 M Bu4NCl. Функцию медиатора выполняют метилвиологен и тетравиологеновые каликс[4]резорцины MVCA-C с метильными (n = 1), н-пентильными (n = 5) и н-децильн…
It is well known that chromium steels are the material for the manufacture of critical parts. Usually parts made out of such materials deformed at room or hot temperature. This paper shows the development mode for deformation under isothermal condition at hot temperatures. The investigation results of chromium steel 1…

Short Glass Fibers (SGF) reinforced thermoplastic are increasingly replacing metals and its alloys with the advent of new polymer alloys and blends. Concurrently the product designs are also becoming more complex, increasing the dependence on simulation software. In order to obtain accurate mathematical and simulation…
Описан принцип действия микроэлектромеханической автоколебательной системы на основе струнного чувствительного элемента с применением монокристаллического кремния и пьезокерамических пленок. Приведены результаты предварительного (качественного) моделирования такой системы, описаны ее особенности.The principle of opera…
V diplomski nalogi je predstavljena problematika masivnih betonov, tj. betonov, pri katerih je potrebna kontrola zaradi povisanja temperature v betonskem prerezu, ki je posledica sproscanja hidratacijske toplote ob vezanju cementa, in s tem povezanim nastankom razpok. Opisana je sestava cementa in vpliv sestave cement…
Bimetallicity is known to provide synergistic effects and improve catalytic performance of monometallic counterparts in a variety of applications. Conventional impregnation methods for supported catalyst preparation do not allow for the control of bimetallic nanoparticle structure or size, which often leads to conside…
Metal–organic frameworks, or MOFs, have emerged as a new class of porous materials made by linking metal and organic units. The easy preparation, structural and functional tunability, ultrahigh porosity, and enormous surface areas of MOFs have led to them becoming one of the fastest growing fields in chemistry. MOFs h…

This dissertation has focused on studying the effect of four glycine derivatives on the solid state properties of mannitol, glycine, and sucrose when freeze dried into blended mixtures. The primary goal was to assess their value for use in the stabilisation of vaccines in the solid state, by examining key physical and…
The issue of prosthetic infection leading to implant failure due to the formation of bacterial biofilms on biomaterial surfaces has been widely recognized as a major issue, often leading to revision surgery. The growing number of patients requiring synthetic biomaterials as implants is on the rise and so is the risk o…
