We demonstrate a heterojunction amorphous Se (a-Se)/organic semiconductor photodetector that extends the long wavelength spectral response of pure a-Se devices from a cutoff of about 500 nm to 1000 nm. We show that a-Se/organic interfaces behave similarly to organic/organic interfaces in terms of energy level alignmen…
Zr65Al7.5Ni10Cu12.5Pd5 bulk metallic glasses (BMGs) in various relaxation states were prepared under different cooling rates. The grain growth rate of the primary quasicrystal was examined near the crystallization temperature. It was approximately 1 × 10−9 m/s in less relaxed BMGs and approximately twice as large in r…
Abstract Novel formaldehyde novolac resins at various molar ratios of monomers (4,4′‐methylenedianiline/p‐nonylphenol/p‐formaldehyde) were synthesized in the presence of an acid catalyst. The obtained resins were characterized by using elemental analysis, FT IR, and 1H NMR spectroscopic methods. Subsequently, these re…
We demonstrate In-assisted desorption of native GaAs surface oxides at substrate temperatures of 480–550 °C. The oxides are removed through production of volatile Ga and In suboxides, Ga2O, and In2O. Compared to a Ga-assisted desorption process, excess In is easily removed at low substrate temperature, favouring a cle…
Differences in the [V 2 Te 2 O 10 ] n 2 n – layer topologies in [C 6 H 16 N 2 ][V 2 Te 2 O 10 ] and [C 5 H 14 N 2 ][V 2 Te 2 O 10 ] are the result of deviations in the C–H···O hydrogen-bonding networks. Stronger influences, such as reagent concentrations and charge density matching, were minimized through the use of b…
Sustained ability to absorb impulses at varied temperatures using light, hard materials and at length scales of few centimeters has been a challenge. The tapered chains while effective have been difficult to construct for applications. Here we build on Hong’s granular protector concept to show that strong inertial mis…
Die Allylalkoholfunktion in der Basalebene von Graphitoxid (GO) lässt sich durch eine sigmatrope Eschenmoser-Claisen-Umlagerung unter Verwendung von N,N-Dimethylacetamiddimethylacetal in N,N-Dimethylamidgruppen umwandeln. Eine anschließende Verseifung dieser Gruppen ergibt die Carbonsäuren (siehe Bild), die bei Deprot…
Abstract Composite hydrogels of poly(acrylamide‐co‐acrylate) with rice husk ash (RHA) were synthesized and studies of the swelling variables were accomplished comparatively with commercial polyacrylamide gel and PAMACRYL, a poly(acrylamide‐co‐acrylate) hydrogel without RHA. FT‐IR and WAXS were the techniques employed…
Real-time in vivo measurements of metabolites are performed by signal enhancement of [1-(13)C]pyruvate using dynamic nuclear polarization, rapid dissolution and intravenous injection, acquisition of free induction decay signals and subsequent quantification of spectra. The commonly injected dose of hyperpolarized pyru…
Geometry plays a major role in our attempts to understand the activity of large molecules. For example, surface area and volume are used to quantify the interactions between these molecules and the water surrounding them in implicit solvent models. In addition, the detection of pockets serves as a starting point for p…
We have developed a method based on the Mie theory for determining the local polymer concentration inside spherical nanoparticles, thereby obtaining vital information about whether the particles are swelling in the solvent or if they are contracted into a more compact structure. In addition, this method can be used to…
Hesperetin, the aglycone of hesperidin present in citrus fruits, possesses various biological activities. We assessed the tissue distribution of hesperetin in rats fed with a 0.2% hesperetin diet for 4 weeks. Its highest concentration was found in the liver, and the second highest was in the aorta. The aorta is assume…
Atomic-scale compositional variation in Ag contents across Ag-Cu-Ni alloy upon being subjected to repeated annealing cycles is shown to result in significant differences in the structure and the thermal stability of ternary alloy nanoclusters. Molecular dynamics (MD) simulations employing quantum Sutton--Chen potentia…
We have performed high-resolution hard-x-ray photoemission spectroscopy for the metal-insulator transition (MIT) system (V${}_{1\ensuremath{-}x}$Cr${}_{x}$)${}_{2}$O${}_{3}$ in the paramagnetic metal, paramagnetic insulator, and antiferromagnetic insulator phases. The quality of the spectra enables us to conclude that…
Complementary circuits, processing digital signals, are a cornerstone of modern electronics. Such circuits require both p- and n-type transistors. Polyelectrolytes are used as gate insulators in organic thin film transistors (OTFTs) to establish an electric double layer capacitor upon gate bias that allows low operati…
The size of (nano) particles is a key parameter used in controlling their function. The particle size is also important in order to understand their physical and chemical properties and regulate their number in health and safety issues. In this work, the geometric diameters of polystyrene spheres of nominal diameter 1…
The Bactigras(®) paraffin tulle coated with chlorhexidine is normally used for the treatment of donor-site wounds in burn patients who received split-thickness skin grafts in several centers. It has some disadvantages, such as adhesion to wound surfaces and pain from the irritation caused by this dressing. The Telfa A…
Many organic and inorganic pollutants, including heavy metals are being transported and mixed with the cultivated soils and water. Heavy metals are the most dangerous pollutants as they are non-degradable and accumulate and become toxic to plants and animals. An experiment was conducted in the glasshouse to evaluate t…
SNX-2112 is a heat shock protein 90 (Hsp90) inhibitor with anticancer properties currently in clinical trials. This study investigated the effects of SNX-2112 on inhibition of cell growth, the cell cycle, and apoptosis in MCF-7 human breast cancer cells, in addition to the various molecular mechanisms. The results of…
Abstract An easy‐to‐use matrix‐based method for the systematic synthesis of distillation configurations using less than n‐1 columns to separate any zeotropic n‐component feed into n product streams is described. The method is easily extended to obtain additional thermally coupled configurations. The only information n…
