quasicrystals are a group of materials with the quasi-periodic structure, and since their discovery in 1980 their specially interesting physical properties have attracted the attention of many researchers. the lack of translational periodicity makes the numerical calculations of their physical properties much more difficult than the crystalline solids. in this work we present a detailed numeric...

To investigate the effect of a liquid crystalline structure on cell behavior, polymethylsiloxane-graft-(10-cholesteryloxydecanol) was specially designed to get a thermotropic liquid crystalline polymer. Results of Fourier transform infrared (FT-IR) spectroscopy, proton nuclear magnetic resonance (1H-NMR) spectroscopy and gel permeation chromatography (GPC) indicated that cholesterol was success...

Crystalline polymers build up complex structural entities, which blend amorphous and crystalline domains at a very small scale (≈ 10 nm). The coexistence of domains, which are of molecular, dimensions stems from the fact that the chains tend to fold upon crystallisation: this chain folding is a characteristic feature of polymers, and creates an organisational scale which is unique to polymers. ...
