Measurements of differential cross sections in the backscattering region
PublikacjaW pracy przedstawiono przegląd technik eksperymentalnych umożliwiających detekcję elektronów rozproszonych w przedziale dużych kątów rozproszenia, ze szczególnym uwzględnieniem techniki lokalnego pola magnetycznego. Przedstawione zostały wyniki pomiarów i obliczeń teoretycznych różniczkowych przekrojów czynnych dla dużych kątów rozproszenia elektronów na atomach gazów szlachetnych i małych molekuł.

Motion of electrons in a hypocycloidal monochromator
PublikacjaBadano zachowanie elektronów w monochromatorze hipocykloidalnym, wykorzystującym jednorodne pole magnetyczne i pole elektryczne o symetrii walcowej. Wyprowadzone zostały równania ruchu elektronów przy założeniu zaniedbywanego wpływu efektów brzegowych oraz zbadano wpływ parametrów monochromatora na tory ruchu elektronów.

Hydration of aprotic donor solvents studied by means of FTIR spectroscopy
PublikacjaThe paper attempts to explain the mutual influence of nonpolar and electron-donor groups on solute hydration,the problem of big importance for biological aqueous systems. Aprotic organic solvents have been used asmodel solutes, differing in electron-donating power. Hydration of acetonitrile, acetone, 2-butanone, andtriethylamine has been studied by HDO and (partially) H2O spectra. The quantitative version of...

Employment of passive sampling in monitoring indoor air quality in selected residences in a Tri-city area in Poland
PublikacjaTime-weighted average concentrations of selected volatile compounds were measured in chosen residences in a Tri-City area of Poland by means of passive sampling. The results were compared to those obtained by dynamic technique – sorption tubes filled with Tenax TA sorbent. Results obtained by employing the two techniques were similar. Total volatile organic compound (TVOC) parameters were also determined. An attempt was also...
