The significant involvement of metal ions and complexes in biological processes and systems has, over recent times, led to the realization that considerable scope exists for the design of metal-based therapeutics. While considerable work in this area has been in the field of coordination complexes, the large diversity…

The effect of carbon modification on electrocatalytic performance of carbon supported Pd catalysts was investigated.Fourier transform infrared(FT-IR) spectrometer,X-ray photoelectron spectroscopy(XPS) and Boehm titration measurements demonstrate that the contents of O-containing groups and N-containing groups on the a…
Although various surface and interface characterization methods have been applied to study the physical wear, corrosion and implant surface interactions with biological environments, presently - in metal on metal (MOM) hip implant- the local and systematic effects of interaction between metal surfaces and protein rich…
Water pollution caused by heavy metals is a serious environmental problem due to their toxicity and the potential of bio-accumulation. Herein, a hyperbranched poly(amidoamine)–anchored membrane was successfully prepared in which hyperbranched poly(amidoamine) (HYPAM) was used as a potential sorbent for the removal of…
Hydrogen is one of the leading choices for alternative environmentally friendly clean energy sources and there is an increasing worldwide interest in the hydrogen economy and hydrogen technologies. One of the main technical challenges presently faced in the production of hydrogen is the cost of purification or the sep…
Diplomova prace se zabýva připravou polymerniho kompozitu na bazi vrstvených siti ze zapletených mnohostěnných uhlikových nanotrubic, ktere jsou zpevněny polystyrenovým filtrem. Kompozit byl připraven filtraci vodne disperze uhlikových nanotrubic přes netkanou pružnou polystyrenovou membranu. Nanotrubice infiltruji ca…
We investigate the recent coincidence of rapid global urbanization and unprecedented formal freedom in architectural design and ask whether this coincidence is an uneasy one. To study an extreme case of the new exotic geometries made possible through CAAD, we employ algebraic surfaces to experimentally design architec…
在衬底加热条件下利用磁控溅射法制备GezSbzTes薄膜，利用x射线衍射仪表征各种沉积温度下薄膜的结构，差示扫描量热法（IgSC）确定的薄膜晶化温度为168℃（加热升温速率为5℃／min）。用四探针法测试薄膜的方块电阻，分光光度计测试薄膜的反射率谱，并根据反射率数据讨论在波长为405和650nrn时薄膜的反射率对比度同沉积温度关系。结果表明：室温沉积的薄膜为非晶态；在衬底温度为140℃条件下薄膜已完全转变为晶态Ge2sb2Te5，在300℃时出现少量的六方相；低于140℃时易形成非Ge2sb2Te，组分的其它晶相，它们对薄膜的电／光性质有很大的影响，可能是导致此类相变光存储薄膜使用过程中反射率对比度下降的原因。
Das Hauptziel dieser Arbeit bestand in der Entwicklung neuer Bariumtitanat-Kondensatorwerkstoffe, die bereits bei 900°C dichtsintern, eine hohe Dielektrizitatskonstante mit geringer Temperaturabhangigkeit sowie geringe dielektrische Verluste und eine hohe Durchschlagfestigkeit aufweisen. Um die Sintertemperatur von Ba…
