Spin alignments in heterospin chains are examined from numerical calculations of model spin Hamiltonians. The Hamiltonians of the heterospin chains mimic an open-shell molecular assemblage composed of an organic biradical in a singlet (S = 0) ground state and a doublet (S = 1/2) monoradical, which are coupled by inter…

Surface effects on the phase separation dynamics, morphologies, and electro-optic properties of thin polymer-dispersed liquid crystal (PDLC) cells are investigated. Four types of surface alignment layers were studied: ITO only, Polyimide (PI) without rubbing, homogeneous cell, and 90° twisted nematic (TN) cell. The IT…

Very high thermal to electric conversion efficiencies have been reported previously with thermal diode structures in which a thin n-type emitter layer is formed on the hot side of a thick near-intrinsic thermoelectric semiconductor. The figure of merit derived from direct measurements of electrical parameters and heat…

In this study, a computational fluid dynamics (CFD) model is applied to study the airflow patterns inside the commingling jets, for different configurations. The CFD package, FLUENT 6.1, is used to predict the two-dimensional flow field inside a yarn channel. The parameters viz. velocity profile, pressure gradient, an…

We use a first-principles calculation and small-angle neutron scattering (SANS) to investigate the mechanism and the nanosize products of the sol-gel reaction with diphenylsilanediol (DPD) and 3-methacryloxypropyltrimethoxysilane (MEMO) precursors in synthesizing a hybrid waveguide material. It is predicted that switc…

A model system for classical fluids out of equilibrium, referred to as a dissipative particles dynamics (DPD) solid, is studied by analytical and simulation methods. The time evolution of a DPD particle is described by a fluctuating heat equation. This DPD solid with transport based on collisional transfer (high-densi…

Les pratiques de fertilisation et d'amendement peuvent contribuer à modifier profondément les propriétés des sols. Ceci est mis en évidence par le dispositif des 42 parcelles de l'INRA à Versailles qui reçoit chaque année les mêmes traitements depuis 1929. Il présente l'originalité d'être en jachère nue. Les résultats…

Die Bildung einer vinylogen Brücke zwischen benachbarten Pyrrolringen (A und B) bei der Reaktion von 5,10,15-Triphenylcorrol mit CI4 führt zum entsprechenden Hemiporphycen (siehe Struktur; N blau, I rosa, C weiß, H grün). Dieser Ansatz eröffnet einen einfachen Zugang zu funktionalisierten Hemiporphycenen.

In this paper we present results related to the self-assembly of different generations of disulfide-cored 2,2-bis(hydroxymethyl)propionic acid-based dendritic structures onto gold surfaces. These molecular architectures, ranging from generation 1 to generation 3, contain removable acetonide protecting groups at their…

CuO supported on Al 2 O 3 -coated cordierite-honeycomb CuO catalysts exhibit high activities for SO 2 and NO removal from flue gas at 400 °C. In a catalyst preparation process, it was found that acid treatment of the cordierite was crucial. This work presents a detailed study on the promoting effect of acid treatment…

The electronic structure and quantum conductance of superlattices made of metallic carbon nanotubes are investigated. It is shown that minibands with the same origin as nonconductive states in metallic quantum dots [L. Chico and W. Jask\'olski, Phys. Rev. B 69, 085406 (2004)] can have a nonzero conductance in superlat…

Analytical solutions to the diffusion equations for fast grain boundary diffusion in polycrystalline solids of finite thickness bounded by two parallel surface planes are presented. The grain boundary diffusion coefficient may be higher by several orders of magnitude than the bulk (volume) diffusion coefficient. The m…

Reactions between solid zinc oxide and molten sodium or potassium pyrosulfates at 500 degrees C are shown by Raman spectroscopy to be 1:1 reactions leading to solutions. By lowering the temperature of the solution melts, colorless crystals form. Raman spectra of the crystals are given and tentatively assigned. Crystal…
