TL;DR: Direct observation by neutron diffraction of superspace symmetry breaking in a solid-solid phase transition of an incommensurate host-guest system: the channel inclusion compound of nonadecane/urea reveals nature's capacity to explore the increased number of phases allowed in aperiodic crystals.

TL;DR: In this paper, three amorphous piezoelectric polyimides have been synthesized and characterized to analyze their utility for high-temperature applications, and they have been prepared from 4,4'-oxydiphthalic anhydride and diamines 2,4-di(3-aminophenoxy)benzonitrile.

TL;DR: In this paper, a single-crystal deuterium NMR study of the phase transition of the incommensurate organic inclusion compound of n-nonadecane in urea is presented.

TL;DR: In this paper, high-resolution light scattering spectroscopy has been performed on a series of n-alkane CnH2n + 2/urea inclusion compounds with n = 12,14,17 − 19.

TL;DR: In this article, the shape memory alloys with high transformation temperatures, between 373 K and 473 k, were investigated and the influence of the alloy concentration and the thermal treatments on the martensitic transformation temperatures was systematically analyzed and a quantitative and predictive equation was proposed.
