A hybrid, organic-inorganic ternary semiconductor with chemical formula (H2NC4H8NCH2CH2NH2)2Zn2Sn2Se7 is reported in which the organic molecules have a dual role, acting simultaneously as ligands and charge balancing cations.

The recently proposed Einstein molecule approach is extended to compute the free energy of molecular solids. This method is a variant of the Einstein crystal method of Frenkel and Ladd [J. Chem. Phys. 81, 3188 (1984)]. In order to show its applicability, we have computed the free energy of a hard-dumbbell solid, of two recently discovered solid phases of water, namely, ice XIII and ice XIV, whe...

the charge transfer (ct) complex formation of benzonitrile as acceptor with the aromatic donors o-, m-, p-xylene and ethylbenzene in ccl4 solutions is investigated by chemical shift measurements relative to an external reference. the equilibrium parameters, q and dad of their weak molecular complexes, as found numerically modified cresswel- allred (c-a) method, is compared with graphically scat...

Strange particles produced in S–Au/W/Pb 200 A GeV and Pb–Pb 158 A GeV reactions are described invoking final hadronic phase space in thermal equilibrium, but allowing chemical non-equilibrium. Several sets of statistical freeze-out parameters are obtained for each system, invoking different models of dense matter. We show that only when allowing for strange and non-strange flavor abundance non-...

This paper involves two intertwined themes. One is the relation of Napoleon Bonaparte (1769-1821) with leading French scientists of his time. The second is the beginning of two concepts important in chemistry: (a) reaction reversibility and chemical equilibrium, and (b) the role of relative masses of reactants and products in determining the position of equilibrium. These ideas are now taken as...

The multiplicities of hadronic species, from pions to omega hyperons created both in elementary, and in highly relativistic nucleus-nucleus collisions, are known to exhibit a pattern that is very well reproduced within the framework of the statistical model as applied, in its canonical form, to the former class of reactions, and in the grand canonical version to the latter. To understand the or...

Hemoglobin is a major constituent of erythrocytes. Because it is non-diffusable and confined within a cell membrane and because of its buffering powers, three major physiochemical equilibria are involved in any acid or base change in blood. Ionic, osmotic and Donnan balance must be main­ tained.16 During the acidosis phase of cell­ ular respiration and increasing Pco2, bi­ carbonate enters eryt...

Recent work on chemical equilibrium in heavy ion collisions is reviewed. The energy dependence of thermal parameters is discussed. The centrality dependence of thermal parameters at SPS energies is presented.

Using ethanol as the carbon source, self-limiting growth of AB-stacked bilayer graphene (BLG) has been achieved on Cu via an equilibrium chemical vapor deposition (CVD) process. We found that during this alcohol catalytic CVD (ACCVD) a source-gas pressure range exists to break the self-limitation of monolayer graphene on Cu, and at a certain equilibrium state it prefers to form uniform BLG with...
