Studies on nanoscale materials have received great interest in both fundamental and applied aspects in recent years. In this letter, we report the synthesis of CoOOH nanorods and their possible applications as coating materials on nickel hydroxide for high-temperature nickel-metal hydride (Ni-MH) cells. The morphology…
Dual emission is observed from a family of simple acetylene-linked dinuclear RuII complexes, where two MLCT excited states coexist at room temperature and in fluid solution. This unique behavior is attributed to a specific substitution pattern on the bridging ligand and provides the opportunity to investigate the stru…
Abstract The complex structure of flax fibres involves many chemical biomolecules located in an amorphous matrix in which cellulose micrifibrils are embbeded. The drying of flax fibres influences significantly their tensile strength. This result can be explained by the creation of damages within the fibre and by the m…
PURPOSE: To establish a novel formulation tumor-targeted drug carrier of lipophilic antitumor antibiotics, aclacinomycin A (ACM), folate-linked microemulsions were prepared and investigated both in vitro and in vivo. EXPERIMENTAL DESIGN: Three kinds of folate-linked microemulsions with different polyethylene glycol (P…
▪ Abstract The preparation of skeletal catalysts is considered, with particular reference to the preparation of skeletal nickel and skeletal copper. Skeletal catalysts have physical properties that are highly desired for some industrial processes, and the means of controlling these properties to optimize performance i…
The problem of self-heating in microelectronic devices has begun to emerge as a bottleneck to device performance. Published models for phonon transport in microelectronics have used a gray Boltzmann transport equation (BTE) and do not account adequately for phonon dispersion or polarization. In this study, the problem…
▪ Abstract It has recently become possible to measure the anisotropic distribution of interfaces in polycrystals and composites. Because classical theories for grain growth and coarsening assume isotropic interface properties, they are incapable of explaining how these distributions arise. The purpose of this paper is…
Thin films fabricated using the glancing angle deposition technique have a porous microstructure consisting of freestanding columns. Many promising applications of such thin films require that the columns be arranged in periodic arrays using substrate topographies-so-called seed layers-that enforce controlled film nuc…
An overview of recent advances in solid-state cooling utilizing thin-film silicon germanium-based microrefrigerators is given. Key parameters affecting micro cooler performance are described. A 3-/spl mu/m thick 200/spl times/ (3 nm Si/12 nm Si/sub 0.75/Ge/sub 0.25/) superlattice device can achieve maximum cooling of…

The reaction product of cobalt carbonyl decomposition depends on the concentration of the oleic acid ligand. With a low concentration of ligand, nanocrystals nucleate and grow to large ferromagnetic particles through the process of Ostwald ripening and coalescence coarsening. With a high concentration of ligand, stabl…
In this paper, a dissipative particle dynamics (DPD) based approach for modeling suspensions is examined. A series of tests is applied comparing simulation results to well established theoretical predictions. The model recovers the dilute limit intrinsic viscosity prediction of Einstein and provides reasonable estimat…
Three cationic PPEs P1 ‘− P3 ‘ were obtained through quaternization of their neutral polymers, of which all side chains were respectively featured with a tertiary amino group ( P1 ), an alternative tertiary amino and tri(ethylene glycol)methyl ether group ( P2 ), and an alternative tertiary amino and dodecyloxy group…
We study anomalous heat conduction and anomalous diffusion in low-dimensional systems ranging from nonlinear lattices, single walled carbon nanotubes, to billiard gas channels. We find that in all discussed systems, the anomalous heat conductivity can be connected with the anomalous diffusion, namely, if energy diffus…
We discuss the relaxation dynamics of glycerol-water mixtures, as studied by dielectric spectroscopy in the frequency range from 1 Hz to 250 MHz and at temperatures between 173 and 323 K. The experimental results obtained for the glycerol-rich mixtures suggest that the main dielectric relaxation process, as well as th…
ABSTRACT: Effects of lactoferrin (LF), lactoferrin hydrolysate (LFH), and lactoperoxidase systems (LPOS), both directly and incorporated into edible whey protein isolate (WPI) films, on the inhibition of Penicillium commune were studied. Mechanical, oxygen‐barrier, and color properties of WPI films with and without LP…
Liquid-core capsules have wide-ranging applications in the high-efficiency encapsulation and controlled release of drugs, dyes, enzymes, and other substrates. Their great utility has driven the rapid development of various preparation techniques. However, there remains no convenient technique for the preparation of su…
Investigation of the growth of CdSe nanocrystals ( approximately 160 atoms) to the uniquely stable size of 2 nm allows the monitoring of the crystallization process in semiconductor quantum dots. By using a combination of optical techniques, high-resolution transmission electron microscopy (HRTEM), and powder X-ray di…
We examine via molecular simulation the dependence of the crystal-melt interfacial free energy $\ensuremath{\gamma}$ on molecular interaction and crystal structure (fcc vs bcc) for systems interacting with inverse-power repulsive potentials, $u(r)=ϵ(\ensuremath{\sigma}/r{)}^{n}$, $6\ensuremath{\le}n\ensuremath{\le}100…
