ZnO nanostructures with a size ranging from 20 to 100 nm were successfully deposited on (1 0 0)-Si substrates at different temperatures (500–800 °C) using MOCVD. It could be confirmed that the size of ZnO nanostructures decreased with increasing growth temperature. From photoluminescence (PL) studies it was found, tha…
A new method for the measurement of solid fuel reactivity towards carbon dioxide has been developed. This new method takes into account high-pressure and temperature effects. Three devolatilized carbonaceous materials have been used in experiments: chars derived from lignite, bituminous coal and blast furnace coke. Pr…
Glass transformation effect of mixed SiO2–P2O5–K2O–MgO–CaO–CuO glasses was studied by DSC, XRD, SEM, and Raman spectroscopy methods. The relationship between the parameters characterizing glass transformation effect and an amount of phosphorous and copper forming the glassy structure was discussed. It was shown that a…
To study the impact of nutritional factors on protein expression of intestinal bacteria, gnotobiotic mice monoassociated with Escherichia coli K-12 were fed three different diets: a diet rich in starch, a diet rich in nondigestible lactose, and a diet rich in casein. Two-dimensional gel electrophoresis and electrospra…
Abstract The creation of artificial three-dimensional (3D) tissues possessing structure and function similar to natural tissue is a key challenge for implantable tissues in tissue engineering, and for model tissues in pharmaceutical assays. This account is a summary of our current research toward this challenge. We ha…
For the magnetic shape memory effect, knowledge about the interaction between martensitic and magnetic domain structure is essential. In the case of Ni-Mn-Ga bulk material and foils, a staircase-like magnetic domain structure with 90°- and 180°-domain walls is known for modulated martensite. In the present paper we sh…
III-V growth and surface conditions strongly influence the physical structure and resulting optical properties of self-assembled quantum dots (QDs). Beyond the design of a desired active optical wavelength, the polarization response of QDs is of particular interest for optical communications and quantum information sc…
A non-linear theory for the plastic deformation of prismatic bodies is constructed which interpolates between Prandtl's linear soap-film approximation and Nádai's sand-pile model . Geometrically Prandtl's soap film and Nádai's wavefront are unified into a single smooth surface of constant mean curvature in three-dimen…
The coalescence-induced condensate drop motion on some superhydrophobic surfaces (SHSs) has attracted increasing attention because of its potential applications in sustained dropwise condensation, water collection, anti-icing, and anticorrosion. However, an investigation of the mechanism of such self-propelled motion…
We have developed the basic equation of the orientational distribution function of oblate spheroidal hematite particles with rotational Brownian motion in a simple shear flow under an applied magnetic field. An oblate spheroidal hematite particle has an important characteristic in that it is magnetized in a direction…
Uniform hexagonal tungsten diselenide (WSe2) nanosheets, with thicknesses as small as 10 nm and diameters as small as 100 nm, self-assembled into tower-like arrays, were successfully synthesized by the solid-state reaction of the elements W and Se in the presence of graphite in a sealed stainless steel reactor at 800°…
The predictions of the generalized collective modes (GCM) theory on the non-hydrodynamic dispersion of collective excitations of liquids and supercritical fluids have been tested against previous inelastic x-ray scattering measurements on samples of increasing complexity. We observed a good agreement between experimen…
Self-aligned triple patterning (SATP) technique offers both improved resolution and quasi-2D design flexibility for scaling integrated circuits down to sub-15nm half pitch. By implementation of active layout decomposition/synthesis using mandrel and spacer engineering, SATP process represents a prospective trend that…
To study the dynamic mechanical kinetics of exfoliated nanocomposites using dynamic mechanical analysis, polyvinyl acetate (PVAc)–montmorillonite (MMT)–dioctadecyl dimethyl ammonium bromide (DOAB) was synthesized through five different processes. Different synthesis processes and MMT-DOAB had little effect on the stru…
Three shell models, differing in accuracy and computational cost, are formulated for two-dimensional Coulomb crystals. Offering a new means of predicting and analyzing properties of these species, the new models also provide new insights into their previously derived three-dimensional counterparts. In particular, anal…
Nanotechnology is one of the most up-to-the-minute areas in essentially all technical disciplines of chemistry, electronics, high-density magnetic recording media, sensors and biotechnology,etc. During the last decade, due to the emergence of a new generation of hightechnology materials, the number of research groups…
Dünne Filme mit cokontinuierlichen Morphologien und charakteristischen Längenskalen bis hinab zu 10 nm wurden durch Phasentrennung eines Polymerblends hergestellt. Der Grad an Nichtmischbarkeit zwischen Polystyrol und Poly(2-vinylpyridin) wurde so eingestellt, dass ungünstige Wechselwirkungen zwischen den beiden Kompo…
Monoammoniated lithium amidoborane has been experimentally synthesized. When this is heated to a temperature of 40–55 °C, this releases 9–11 wt % hydrogen. First-principles density functional calculations have been carried out to understand the underlying mechanism of dehydrogenation. Theoretical results predict that…
The successful growth of carbon nanotubes (CNTs) on montmorillonite (MMT) precursors treated with different concentrations of ferric nitrate at 50 °C (MMT(Fe)-50) and 100 °C (MMT(Fe)-100) was achieved via the in situ chemical vapor deposition (CVD) of acetylene. The as-obtained MMT-CNTs composites were characterized u…
Purpose The purpose of this paper is to develop hybrid copolymers through the copolymerisation of a novel low molecular weight oleic acid‐based macromer with methyl methacrylate (MMA), with the aim of combining the good properties of alkyd and acrylic binders. Design/methodology/approach The macromer was synthesised f…
