Detailed investigation of the phase transition inKxP4W8O32and experimental arguments for a charge density wave due to hidden nesting
PublicationDetailed structural and magnetotransport properties of monophosphate tungsten bronze Kx(PO2)4(WO3)8 single crystals are reported. Both galvanomagnetic and thermal properties are shown to be consistent with a charge density wave electronic transition due to hidden nesting of the quasi-1D portion of the Fermi surface. We also observe the enhancement of electronic anisotropy due to reconstruction of the Fermi surface at the Peierls...

Właściwości otoczki hydratacyjnej wokół różnych konformacji poliseryny - analiza wyników dynamiki molekularnej
PublicationRozpuszczalnik w istotny sposób wpływa na preferencje peptydu do przyjmowania określonej struktury drugorzędowej. Przykładem tego może być fakt, iż w przypadku polialaniny stabilność konformacji helikalnej w wodzie jest niższa aniżeli w próżni, podczas gdy w przypadku poliseryny mamy do czynienia ze zjawiskiem odwrotnym. W celu lepszego zrozumienia tego zjawiska badano właściwości otoczek hydratacyjnych dookoła czterech konformacji...

Design Analysis of Micro Gas Turbines in Closed Cycles
PublicationThe problems faced by designers of micro-turbines are connected with a very small volume flow rate of working media which leads to small blades’ height and high rotor speed. In the case of gas turbines this limitation can be overcome by the application of a closed cycle with very low pressure at the compressor inlet (lower than atmospheric pressure). In this way we may apply a micro gas turbine unit of accepted efficiency to work...

A novel concept of negative CO2 emission power plant for utilization of sewage sludge
PublicationCarbon Capture and Storage (CSS) technology is considered an important “bridge technology”, allowing effective abatement of CO2 emissions for power units using fossil fuels. However, if biomass is used in a power plant, equipped with CCS system, negative CO2 emissions can be achieved. In practice, wide development of such technologies would enable not only reduction of CO2 emissions, but also reversal of the harm done so far. In...
