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…
Durch die Nutzung von erneuerbaren Rohstoffen und Kohlendioxid wurden in der vorliegenden Arbeit neuartige thermo- und duroplastische bio-basierte Werkstoffe synthetisiert und deren grundlegenden Struktur/Eigenschafts-Beziehungen aufgeklärt. Wichtiges Ziel war die Polykondensation von kristallisationsfähigen langketti…
The energy absorption for uniform and graded foam core composite sandwich structures was investigated under low and high velocity impact by using drop-weight tower and gas gun.
Da eine Fehlfunktion des Noradrenalintransporters bei vielen verschiedenen Krankheiten wie Aufmerksamkeitsdefizidsyndrom, Kokainabhängigkeit und Aktivierung von braunem Fettgewebe eine wichtige Rolle spielt, ist die Untersuchung dieses Transporters von großem Interesse. Ziel dieser Diplomarbeit war die Synthese von Re…
En este trabajo se propuso zeolitizar una ceniza volante industrial a través de un proceso hidrotermal. Para ello, se probó mejorar su reactividad sometiéndola a un pretratamiento de calcinación en presencia de compuestos fundentes como Na2CO3, NaOH y ClNa. Fue también pretratada por molienda. Una vez activada, se pre…
This paper provides details on how to enhance antenna performance and size reduction using Split Ring Resonator (SRR). The size and weight of various wireless electronic systems have been rapidly reduced due to the development of modern integrated circuit technology. Microstrip Patch Antennas (MPA) are increasing in p…
In this thesis, a characterization of flame sprayed aluminium 12silicon (Al 12Si) coatings as an electrical structural health monitoring (SHM) sensor for fibre reinforced polymer composite (FRPC) structures is presented. Flame sprayed Al 12Si coatings were deposited onto FRPC tubes and laminates. The effect of the fla…
