According to the Polish Standards PN-C-96050, the term waste petroleum oils refers to the kerosene or ester oil products which have lost their exploitation value. Polish market annually receives over 300 thousand tons of an assortment of lubricating, gear and spindle oils, part of which is used up in exploitation and the rest is left as waste. The subject of our study was to check the possibility of combined distillation of the waste petroleum oil with a certain amount of fine plastics waste such as: polyethylene, polypropylene, polystyrene or poly(ethylene terephthalate). These polymers undergo thermal decomposition in relatively low temperatures (250 - 400°C), into gas, liquid (mostly) and solid products. The experiment was performed for 5, 10 and 15 wt.% addition of the polymers to the loading. The gas products formed in the process of distillation can be combusted, while the solid waste (coal deposit) is used as fuel in e.g. cement plants.

The amounts of mRNA of subunit-c (proteolipid) of the V-ATPase of mature leaves of Mesembryanthemum crystallinum L. in the state of C3-photosynthesis were analyzed for a time-series of 96 h under constant conditions in continuous light. Fourier-transform analysis of the data showed endogenous oscillations of the mRNA with period lenghts of 48, 24 and 12 h, i.e. harmonic frequency resonances.

Different methods and techniques for material characterization are often used as a standard procedure for the determination of material properties. Nuclear techniques provide new and more detailed information about the investigated materials. The main goal of the carried out experiments was to improve surface properties including wear, corrosion and high temperature oxidation resistance. Modification processes were carried out using high intensity pulsed plasma beams - HIPPB (106-108 W.cm-2) generated in a rod plasma injector (RPI). In most solid materials such treatment leads to a fast transient melting of the surface layer of the substrate followed by rapid crystallization. Heating and cooling processes are of non-equilibrium type. Initial and modified materials were characterized using different investigation methods including nuclear techniques. Results of the used nuclear techniques such as nuclear reaction analysis (NRA), Rutherford backscattered spectroscopy (RBS) and conversion electron Mössbauer spectroscopy (CEMS) are presented in the paper.

Przedstawiono wyniki prób osadzania azotku galu na podłożach z węglika krzemu w technologii epitaksji ze związków metalorganicznych w fazie pary w obniżonym ciśnieniu (LP MOVPE). W szczególności zbadano wpływ trawienia podłoży oraz ich odchylenia od osi (0001) na morfologię powierzchni oraz strukturę krystalograficzną osadzanego GaN. Stwierdzono, że trawienie podłoży ma wpływ na chropowatość powierzchni warstw epitaksjalnych, ale również poprawia strukturę krystalograficzną. Warstwy GaN zostały scharakteryzowane przy wykorzystaniu pomiarów AFM, HRXRD, RBS oraz pomiaru efektu Hall'a. Zaobserwowano, że najbardziej odpowiednim z analizowanych podłoży do epitaksji GaN jest 4H-SJC są te, które nie mają odchylenia od osi kryształu (0001).

The influence of surface preparation and off-cut of 4H-SiC substrates on morphological and structural properties of GaN grown by low pressure metalorganic vapour phase epitaxy was studied. Substrate etching has an impact on the surface roughness of epilayers and improves its crystal quality. The GaN layers were characterized by AFM, HRXRD, RBS/channelling and Hall effect measurements. It was observed that on-axis 4H-SiC is most suitable for GaN epitaxy and that substrate etching improves the surface morphology of epilayer.
