Thin film magnetization reversal without applying external fields is an attractive perspective for applications in sensors and devices. One way to accomplish it is by fine-tuning the microstructure of a magnetic substrate via temperature control, as in the case of a thin Fe layer deposited on a MnAs/GaAs(001) template…
Abstract BACKGROUND Beta‐cyclodextrin (β‐ CD ) has a hydrophilic exterior and a hydrophobic internal cavity which gives it the ability to form a host–guest complex. Sodium alginate ( NaAlg ) is a natural polysaccharide which can form a hydrogel in the presence of divalent cations. RESULTS The degree of substitution (…
Diacetylene-containing glycolipids are a unique class of compounds that are able to self-assemble and form ordered supramolecular structures. Polymerizable diacetylene glycolipids that can function as low molecular weight gelators are particularly interesting molecules which can lead to stimuli-responsive smart materi…
The development of new, high performance reduced activation materials is increasingly recognised as one of the key enabling technologies required for the advancement of civil fusion power. Reduced activation steels are considered the leading materials for fusion reactor blanket structural materials. The manufacturing…
Quantum dots at the hexane-glycerol interface exhibited unexpected behavior including highly dynamic adsorption/desorption, where the lateral nanoparticle motion was anomalously fast immediately after adsorption and prior to desorption. At the interface, particles exhibited pseudo-Brownian lateral motion, in which the…
By excluding metals from synthesis, growth of carbon nanostructures via unreduced oxide nanoparticle catalysts offers wide technological potential. We report new observations of the mechanisms underlying chemical vapor deposition (CVD) growth of fibrous carbon nanostructures from zirconia nanoparticles. Transmission e…
Protein characterization in situ remains a major challenge for protein science. Here, the interactions of ΔTat-GB1 in Escherichia coli cell extracts were investigated by NMR spectroscopy and size exclusion chromatography (SEC). ΔTat-GB1 was found to participate in high molecular weight complexes that remain intact at…
The detailed structural evolutions in polycarbosilane-derived carbon-rich amorphous SiC were investigated semiquantitatively by combining experimental and analytical methods. It is revealed that the material is comprised of a Si-containing matrix phase and a free-carbon phase. The matrix phase is amorphous, comprised…
Abstract Well‐dispersed PtNi nanoparticles (NPs) grown on carbon nanodots (CNDs) derived from a metal–organic framework (ZIF‐8) are synthesized by a simple reduction of metal precursors in the presence of CNDs, wherein the CNDs prove to be a powerful dispersion agent and distinct support for the PtNi NPs. The resultan…
We report for the first time, a green method for graphene–iron oxide nanocomposite (GINC) synthesis by dispersing graphene and nano iron oxide (Fe <sub>2</sub> O <sub>3</sub> ) in ethanol <italic>via</italic> ultrasonication followed by micro-wave irradiation.
Based on SHG-density and band-resolved analysis, we find that the BO <sub>4</sub> groups and the metal cation are the main contributors to the SHG effect in MBPO <sub>5</sub> (M = Ba, Sr), and not the PO <sub>4</sub> groups as previously anticipated.
The binding affinity of explosive molecules with 2D BN flakes is higher than G flakes due to more charge transfer in the BN-explosive complexes.
The effect of multilevel inverter supply on power losses in magnetic cores and electrical machines is studied. A dynamic numerical model for the hysteresis, eddy current, and excess losses in a core lamination is first developed. By both measurements and simulations for a ring-core inductor, we demonstrate how increas…
Ionic sulfophosphate liquids of the type ZnO-Na2O-Na2SO4-P2O5 exhibit surprising glass forming ability, even at slow or moderate cooling rate. As a concept, they also provide high solubility of transition metal ions which could act as cross-linking sites between the sulfate and phosphate entities. It is therefore inve…
In the present study gentamicin was encapsulated within calcium alginate beads and incorporated into porous chitosan, gelatin, double-hybrid silk fibroin, chitosan/gelatin and double-hybrid silk fibroin/chitosan scaffolds. Physiochemical, morphological and biological properties of fabricated amenable model systems wer…
Tellurite glass fibers with embedded nanodiamond are attractive materials for quantum photonics applications. Reducing the loss of these fibers in the 600-800 nm wavelength range of nanodiamond fluorescence is essential to exploit the unique properties of nanodiamond in the new hybrid material. The first part of this…
The aim of this work was to prepare pH-sensitive drug carriers for colon specific drug delivery through a completely green and environmentally friendly route (without using any organic solvents, hazardous chemicals and even a harsh procedure).
We report a self-developing anisotropic gold/polymer hybrid nanosystem that precisely places dye molecules at the plasmonic hotspot of metal nanostructures for sensing and photonics applications. Unlike conventional molecule–particle configurations, the anisotropic hybrid nanosystem (AHN) introduces an anisotropic spa…
Heat capacity measurements were performed for Se, Se90Te10, Se80Te20, and Se70Te30 materials in the 230-630 K temperature range. Both glassy and crystalline Cp dependences were found to be identical within the experimental error. The compositional dependence of the N-type undercooled liquid Cp evolution was explained…
Stretchable plasmonic nanostructures constituted by Ag nanoparticles on flexible elastomeric matrices are synthesized and used as surface-enhanced Raman scattering (SERS) substrates.
