We report a homoleptic Au-Cu alkynyl cluster that represents an unexplored class of luminescent materials with stimuli-responsive photophysical properties. The bimetallic complex formulated as [Au(2)Cu(2)(C(2)OHC(5)H(8))(4)](n) efficiently self-assembles from Au(SC(4)H(8))Cl, Cu(NCMe)(4)PF(6), and 1-ethynylcyclopentan…
Time-resolved threshold switching characteristics including transient parameters such as delay time and holding voltage are reported for a nanoscale GeTe6 Ovonic threshold switching (OTS) device. The voltage dependence of the threshold switching process has been studied, revealing switching in less than 5 ns in the fa…
New layered SnS 2 nanosheet arrays consisting of 1–5 atomic layers were synthesized directly on Sn foil as both the tin source and the metal current collector substrates by a simple biomolecule-assisted method. It is found that SnS 2 nanosheets synthesized have excellent photoelectric applications, such as on lithium…
Abstract PbTe alloys have been the most efficient materials for thermoelectric power generation since the 1950s. In addition to the observed lattice thermal conductivity reduction by alloy scattering, recent efforts targeting electronic‐transport enhancement through band structure engineering have demonstrated a desig…
Nanostructures, particularly those from peptide self-assemblies, have attracted great attention lately due to their potential applications in nanotemplating and nanotechnology. Recent experimental studies reported that diphenylalanine-based peptides can self-assemble into highly ordered nanostructures such as nanovesi…
BACKGROUND: To better understand the potential ecotoxicological impacts of silver nanoparticles released into freshwater environments, the Daphnia magna 48-hour immobilization test was used. METHODS: The toxicities of silver nitrate, two types of colloidal silver nanoparticles, and a suspension of silver nanoparticles…
We report highly bright and efficient inverted structure quantum dot (QD) based light-emitting diodes (QLEDs) by using solution-processed ZnO nanoparticles as the electron injection/transport layer and by optimizing energy levels with the organic hole transport layer. We have successfully demonstrated highly bright re…
Excessive production of superoxide in the central nervous system (CNS) has been implicated in many brain‐related cardiovascular diseases, including hypertension. However, therapeutic potential of antioxidant therapies has been limited by restricted transport across the blood‐brain barrier and poor pharmacodynamics. To…
In the present study, a centric diatom Chaetoceros minimus is reported for the first time from the Indian waters. This record will contribute to the phytoplankton checklist of Indian seas. Morphological characteristics and distribution of the species are provided.
In this study, the mechanical properties of five different cement based repairing materials were evaluated. These materials were classified into two groups: laboratory made materials with or without admixtures (3 types), and other two types of commercial proprietary pre-packaged with additives. Mechanical properties,…
The paper describes the possibility of improving the pore structure and adsorption properties of industrial active carbons (AC) by means of their modification with ɛ-caprolactam (CL). Application of ɛ-caprolactam (a product of large-scale organic synthesis) as a modifying substance allows the targeted regulation of th…
Our SOURCE software handles 2D simulation and design of electron guns, including thermionic, thermal field and cold field emission guns, with electrostatic and magnetic focusing. The fields are computed by Second-Order Finite Element Method, which can handle large scale changes, curved cathodes and electrodes. Space c…
The objective of this study was to synthesize shellac phthalate succinate (SHL-PHT-SUC) through organic solvent-free reaction. Firstly, shellac phthalate (SHL-PHT) was prepared by co-grinding and annealing shellac (SHL) with phthalic anhydride (PHTA). The SHL-PHT was subsequently ground with succinic anhydride (SUCA)…
In this research Bi2O3 was doped with mixtures of 8, 10, 12 and 18 mol % of Y2O3 and Yb2O3 to stabilizing the δ-Bi2O3 phase using solid state reaction technique. Experimental samples were fabricated by isostatic pressing and sintering at 850 °C for 24 h. X-ray diffraction analysis detected cubic phase (δ-Bi2O3) as the…
The evolution of recrystallization texture in the non-orientation electrical steel containing copper during annealing at 950°C for 3～180s have been studied by EBSD (Electron Backscatter Diffraction) measurements. Goss grains({011}) are nucleated within shear bands in deformed {111} and{111} grains. {111} grains nuclea…
Abstract Incorporation of silver nanoparticles enhances the biocide functionality of Ag supported kaolinite/metakaolite materials.
