W monografii przedstawiono nowe wyniki badań struktury i korelacji molekularnych wybranych cieczy molekularnych i roztworów cieczy. Badania rentgenowskie dotyczyły roztworów niektórych cieczy polarnych z rozpuszczalnikiem niedipolowym.

W pracy opisano również rentgenowską metodę wykrywania zmian nowotworowych.

W pracy sformułowano nową metodę analizy struktury materii miękkiej. Zastosowano metodę redukcji zaproponowaną przez Mozziego i Warrena z modyfikacjami wprowadzonymi przez autora. Funkcje zredukowanego natężenia promieniowania analizowano metodą Bluma i Nartena. Zaproponowano najbardziej prawdopodobne binarne korelacje radialne molekuł w cieczach i roztworach ciekłych.

Znajomość budowy molekularnej cieczy i mechanizmu zachodzącej w nich dyfuzji ma fundamentalne znaczenie dla wszechstronnego wyjaśnienia ich właściwości fizyko-chemicznych.

Literature

In the monograph presents new results of studies on the structure and molecular correlations in selected molecular liquids and liquid solutions. X-ray investigations concerned solutions of certain dipolar liquids with non-dipolar solvent.

This work also describes the X-ray method of detection of neoplasmic changes.

In this work the new method of the soft matter structure analysis was formulated. The method of reduction proposed by Mozzi and Warren with modifications introduced by the author has been applied. The functions of reduced radiation intensity were analysed by the method of Blum and Narten. The most probable binary radial correlations of molecules in liquids and liquid solutions have been proposed. The knowledge of molecular structure of liquids and the mechanism of the diffusion taking place in them is of fundamental importance in comprehensive explanation of their physical and chemical properties.
