Synthesis of 2,6-diaminopimelic acid (DAP) and its analogues
PublicationKwas 2,6-diaminopimelinowy jest ważnym aminokwasem biosyntetyzowanym przez bakterie i wyższe rośliny. Liczne fragmenty peptydoglikanu zawierające reszty kwasu diaminopimelinowego wykazują aktywność przeciwnowotworową i/lub immunostymulacyjną. W artykule opisano sposoby syntezy kwasu 2,6-diaminopimelinowego i jego analogi.

Electroanalytical and spectroscopic procedures for examination of interactions between double stranded DNA and intercalating drugs
PublicationPrzedstawiono metodę elektrochemicznego opisu oddziaływań dsDNA ze związkiem biologicznie czynnym w warunkach, w których zarówno badany związek jak i cząsteczka DNA są w roztworze elektrolitu. Opracowano warunki pomiaru, gdzie ani związek, ani DNA nie adsorbuje na elektrodzie. Wykazano, podobnie jak podczas badania innymi metodami, że oddziaływania są dwojakiego rodzaju: elektrostatyczne i poporzez interkalację.

Measurements of differential cross sections in the backscattering region
PublicationW 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
PublicationBadano 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
PublicationThe 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...
