Nesta dissertação, apresenta-se o trabalho realizado no decorrer do segundo ano do Mestrado em Bioquímica Aplicada. Prepararam-se nanopartículas metálicas através da redução química de sais metálicos em solução. Obtiveram-se soluções coloidais monometálicas de Au, Ag e FeOx e bimetálicas de Au/Ag, Ag/Au, FeOx/Au e FeO…
Предлагаем и оптимизируем конструкцию радиопрозрачных перегородок в волноводе с существенно улучшенным согласованием с трактом в широком диапазоне частот. Это – ленточная диафрагма внутри слоя диэлектрика. На этой основе создан также эффективный абсорбер.
Polifenoli su sloţena biljna, polusintetska i sintetska organska jedinjenja. Hrana sadrţi smešu različitih polifenola, a posebno voće i povrće, zeleni i crni čaj, crveno vino i dr. Nedavna istraţivanja govore u prilog značajne uloge polifenola u prevenciji kardiovaskularnih oboljenja, karcinoma, osteoporoze, neurodege…

Os materiais metalicos biomedicos apresentam notavel importância na reconstrucao de tecidos estruturais que falharam. Atualmente, a producao de novas ligas de titânio tem sido incentivada para uso biomedico a fim de reduzir as limitacoes quanto ao modulo de elasticidade e citotoxicidade das ligas comercializadas, em p…
This Master's thesis deals with the use of block copolymers in capillary electromigration techniques (literature part) and both in material chemistry and capillary electrophoresis (experimental part). Amphiphilic block copolymers are an interesting research topic due to their specific molecular structure, which consis…
The main objective of this thesis is to study the fundamental behaviour of multi-component gas mixture flows in micro/nano-channels undergoing catalytic chemical reactions on the walls. \n This work is primarily focused on nano-scale reacting flows seen in related applications; especially, miniaturized energy sources…
Da bi namjestaj bio kvalitetan, bitno je prije svega naglasiti da svi dijelovi koji se upotrebljavaju za izradu namjestaja moraju biti kvalitetni. M
Nanoparticle materials are good candidates as shuttles of drug delivery and contrast agents in different biomedical imaging modalities such as magnetic resonance imaging (MRI), computed tomography (CT), ultrasound tomography, and optical imaging based on their special properties in magnetism, acoustics, optics, and el…
Alzheimer’s disease (AD) is a progressive dementia affecting cognition, behavior, and functional status and there is no cure which exists for it. In AD, Amyloid Beta (Aβ) peptides form aggregates that are neurotoxic in the brain. Hence, molecules that are able to prevent Aß aggregation could be effective in AD treatme…
The title compound, [Fe(C44H28N4)(C6HF4O)], is a porphyrin complex with iron(III) in fivefold coordination with a tetra-fluoro-phenolate group as the axial ligand. The Fe atom and the phenolate ligand are disordered across the porphyrin ring with the two phenolates appearing to be roughly related by a center of symmet…

Ljepila su tvari koje služe za spajanje prijanjanjem dijelova iz istih ili razlicitih materijala. Ljepljenje se zasnima na fizikalnom principu adhez
Okpoka Creek of the Upper Bonny Estuary in the Niger Delta is a sink under tidal effects. The study investigated the influence of low and high tides on the species composition, diversity, abundance and distribution of epiphyton. The epiphyton samples were collected monthly from May 2004–April 2006 at both tides from t…

In Brief Radioactive lightning rods (RLR) were manufactured and installed in Brazil for almost two decades, before they were prohibited in 1989. Structures protected by this type of lightning preventers included residential buildings, schools, commercial and industrial facilities, among others. It is estimated that ab…
