W poszukiwaniu układu okresowego dla materii w skali nano

The purpose of this article was a presentation of the state of the art in the search of the periodic system for matter in nanoscale. It was preceded by a history of the discovery of traditional periodic table of the elements just to bring out the possible analogies to help in the analysis. Finally, the „road map” by Tomalia and Khanna [D.A. Tomalia, S.N. Khanna, Chem. Rev., 2016, 116, 2705] leading to a future periodic system unifying nanoscience was presented.

Soft Matter Physics and its Creator : Pierre-Gilles De Gennes (1932–2007) in Memoriam

Pierre-Gilles de Gennes passed away on 18 May 2007. The Royal Swedish Academy of Sciences decided to award the 1991 Nobel Prize in physics to him “for discovering that methods developed for studying order phenomena in simple systems can be generalized to more complex forms of matter, in particular to liquid crystals and polymers” [1]. He is still the only scientist dealing with polymer science who has been a Nobel Prize winner in physics; therefore, it was justified to commemorate his work and achievements during the session of the Seventh International Conference on X-Ray Investigations of Polymer Structure.

Pierre-Gilles de Gennes zmarł 18 maja 2007 r. Szwedzka Królewska Akademia Nauk zadecydowała przyznać mu Nagrodę Nobla z fizyki w 1991 roku za „odkrycie, że metody stosowane do badania zjawisk uporządkowania w prostych układach, mogą być uogólnione na bardziej złożone rodzaje materii, w szczególności ciekłe kryształy i polimery”. Jest on wciąż jedynym uczonym pracującym w nauce o polimerach, który został wyróżniony Nagrodą Nobla z fizyki.

Computer simulation of the Poisson's ratio of soft polydisperse discs at zero temperature

A simple algorithm is proposed to study structural and elastic properties of matter in the presence of structural disorder at zero temperature. The algorithm is used to determine the properties of the polydisperse soft disc system. It is shown that Poisson's ratio of the system essentially depends on the size polydispersity parameter; larger polydispersity implies larger Poisson's ratio. In the presence of any size polydispersity, Poisson's ratio increases also when the interactions between, the particles tend to the hard potential.
