The enhanced interest of the researchers in nanoobjects is due to the discovery of unusual physical and chemical properties of these objects, which is related to manifestation of so-called ‘quantum size effects‘. These arise in the case where the size of the system is commensurable with the de-Brogli wavelengths of the electrons, phonons or excitons propagating in them.A key reason for the chan...

This paper introduces APA (“Artificial Prion Assembly”): a pattern recognition system based on artificial prion crystalization. Specifically, the system exhibits the capability to classify patterns according to the resulting prion selfassembly simulated with cellular automata. Our approach is inspired in the biological process of proteins aggregation, known as prions, which are assembled as amy...

The title salt, C(14)H(16)N(4) (2+)·2C(14)H(9)O(4)S(2) (-)·2H(2)O, was obtained by the co-crystalization of 2,2'-dithio-dibenzoic acid with 1,4-bis-(imidazol-1-ylmeth-yl)benzene. It consists of 2-[(2-carb-oxy-phen-yl)disulfan-yl]benzoate anions, centrosymmetric 1,1'-(p-phenyl-enedimethyl-idene)diimidazol-3-ium cations and water mol-ecules. O-H⋯O, O-H⋯S and N-H⋯O hydrogen-bonding inter-actions a...

We investigate the orientational order of transverse polarization vectors of long columns of nucleosomal core particles and their coupling to positional order in high density mesophases discovered recently. Inhomogeneous polar ordering of these columns precipitates crystalization of the 2D sections with different orientations of the transverse polarization vector on each column in the unit cell...
