XPS study of the NH4-VOx powders
Dane BadawczeVanadium pentoxide samples were prepared by sol-gel method. The starting solution was prepared by mixing vanadium (V) oxytripropoxide (Aldrich) in an anhydrous ethanol as solvent and acetylacetone. By drying the sol at 323 K for 48 h, it transforms via gel into a xerogel powder. Next, the precursor powder was pressed into the disk-shaped pellets. Samples...

Asian Powers in Eu Policy
PublikacjaEU policy towards Japan, China, India and South Korea has evolved. This allows the separation of its three stages: before the EU, early EU and mature EU. The global ambitions of the EU, as expressed, inter alia, for the CFSP, is determined to strengthen cooperation with Asian powers, as well as strategic partnerships. The powerful attributes of the strongest Asian states are varied. On the one hand the many similarities and common...

Fibrillar aggregates in powdered milk
PublikacjaThis research paper addresses the hypothesis that powdered milk may contain amyloid fibrils. Amyloids are fibrillar aggregates of proteins. Up to this time, research on the presence of amyloids in food products are scarce. To check the hypothesis we performed thioflavin T fluorescence assay, X-ray powder diffraction, atomic force microscopy and fluorescence microscopy imaging. Our preliminary results show that commercially available...

Simulating Power Generation from Photovoltaics in the Polish Power System Based on Ground Meteorological Measurements—First Tests Based on Transmission System Operator Data
PublikacjaThe Polish power system is undergoing a slow process of transformation from coal to one that is renewables dominated. Although coal will remain a fundamental fuel in the coming years, the recent upsurge in installed capacity of photovoltaic (PV) systems should draw significant attention. Owning to the fact that the Polish Transmission System Operator recently published the PV hourly generation time series in this article, we aim...

Mercury emission from coal-fired power plants in Poland
PublikacjaPrzedstawiono główne źródła emisji rtęci w Polsce. W zwiazku z dużą ilością spalanego węgla, jak również planami na przyszłość węgiel kamienny i brunatny jest i będzie podstawowym źródłem produkcji energii w Polsce. Ponieważ węgiel zawiera rtęć, to podczas spalania węgla rtęć uwalniania jest do atmosfery. Spalanie węgla w elektrowniach jest i będzie w najbliższym czasie głównym źródłem emisji rtęci w Polsce. W pracy opisano metody...
