INTERFACE THERMAL RESISTANCE BETWEEN FRENKEL-KONTOROVA AND FERMI-PASTA-ULAM LATTICES
By connecting two dissimilar anharmonic lattices exemplified by Fermi-Pasta-Ulam (FPU) model and Frenkel-kontorova (FK) model, we successfully build up one dimensional thermal diode. We find the rectifying effect is closely related to asymmetric interface thermal resistance (Kapitza resistance). And the asymmetric the…
Chemistry of metallasiloxanes. Current trends and new concepts
The current status of the chemistry of metallasiloxanes is surveyed. Synthetic methods affording the metallasiloxane fragments and specific transformations of metallasiloxanes governed by the coordination properties of the metal site are analysed. The emphasis is placed onto the formation of compounds with the metalla…
Precise measurements of electron and hole g-factors of single quantum dots by using nuclear field
We demonstrated the cancellation of the external magnetic field by the nuclear field at one edge of the nuclear polarization bistability in single InAlAs quantum dots. The cancellation for the electron Zeeman splitting gives the precise value of the hole g-factor. By combining with the exciton g-factor that is obtaine…
Topological and topological-electronic correlations in amorphous silicon
In this paper, we study several structural models of amorphous silicon, and discuss structural and electronic features common to all. We note spatial correlations between short bonds, and similar correlations between long bonds. Such effects persist under a first principles relaxation of the system and at finite tempe…
Synthesis of Zinc Oxide Nanostructures with Controlled Morphologies Using a Simple Sonochemical Method
Zinc oxide (ZnO) nanostructures were synthesized by a simple sonochemical method without the assistance of an additional surfactant. The morphologies can simply be controlled only by changing the addition sequence of NH 3 ·H 2 O. When NH 3 ·H 2 O was added before or at the beginning of the ultrasonic treatment, a flow…

Purpose The purpose of this paper is to investigate the effectiveness of commercial clothes dryers based on energy‐efficiency and environmental impact analyses. Design/methodology/approach The study consisted of reviewing and examining the energy consumption of clothes dryers. It adopted the US Department of Energy's…
Nanostructured Biodegradable Polymer Composites Generated Using Lyotropic Liquid Crystalline Media
In tissue engineering applications the physical properties and degradation behavior of the designed synthetic scaffold are crucial for successful growth and function of desired tissue. Combining two or more biodegradable polymers into a single biomaterial composite may provide a pathway toward achieving new and highly…
Air and Water Free Solid-Phase Synthesis of Thiol Stabilized Au Nanoparticles with Anchored, Recyclable Dendrimer Templates
Solid-phase synthetic templates for Au nanoparticles were developed using Merrifield resins and polyamidoamine (PAMAM) dendrimers. This synthetic scheme affords the opportunity to prepare metal nanoparticles in the absence of air and water, and it does not necessitate phase transfer agents that can be difficult to rem…
Nanocrystals to Nanorods: A Precursor Approach for the Synthesis of Magnesium Hydroxide Nanorods from Magnesium Oxychloride Nanorods Starting from Nanocrystalline Magnesium Oxide
Nanorods of magnesium oxychloride (Mg x (OH) y Cl z · n H 2 O) and magnesium hydroxide (Mg(OH) 2 ) have been produced from crystalline MgO. Concentrated aqueous magnesium chloride (MgCl 2 ·6H 2 O), when allowed to react with MgO, yields oxychloride nanorods that can be converted into Mg(OH) 2 nanorods using NaOH, with…
Development ofN-Alkyl-Substituted Bis(pyrrolo[3,4-d])tetrathiafulvalenes as Organic Semiconductors for Solution-Processible Field-Effect Transistors
A series of N -alkyl-substituted bis(pyrrolo[3,4- d ])tetrathiafulvalenes (PyTTFs, alkyl = n -butyl, n -octyl, n -dodecyl, n -cetyl, and n -icosyl, 3 − 7 ) were synthesized as highly soluble tetrathiafulvalene (TTF) derivatives. Their solid-state structures were characterized by X-ray diffraction, and their suitabilit…

Using (51)V magic angle spinning solid-state NMR, SSNMR, spectroscopy and quantum chemical DFT calculations we have characterized the chemical shift and quadrupolar coupling parameters of a series of eight hydroxylamido vanadium(V) dipicolinate complexes of the general formula VO(dipic)(ONR1R2)(H2O) where R1 and R2 ca…
Assembly of Copolymer Blend on Nanopatterned Surfaces: A Molecular Simulation Study
We report a molecular simulation study on the assembly of an (A7B5)5/A7B5 copolymer blend on nanopatterned surfaces. The density distributions, anisotropic radii of gyration, and conformations of both copolymers are quantitatively characterized. As the width of stripes on the surface decreases, the shape and thickness…
