The manipulation of the ferromagnetic magnetization via electric fields is investigated in Ni/BaTiO3 hybrid structures. The application of an electric field to the ferroelectric BaTiO3 induces elastic strain. In the Ni/BaTiO3 hybrids, this strain is transferred into the ferromagnetic Ni layer, affecting its magnetizat…
IMPORTANCE OF THE FIELD: Active targeting of bioactive molecules by physicochemical association with hyaluronic acid (HA) is an attractive approach in current nanomedicine because HA is biocompatible, non-toxic and non-inflammatory. AREAS COVERED IN THIS REVIEW: This review focuses on synthesis, physicochemical charac…
We reported a method to fabricate fluorescent probes preferentially end-linked to Au nanorods. In comparison with organic dyes, the single nanocomplexes provide significant improvement in signal brightness. The bioconjugated nanoantenna structure implicates an approach that is more convenient and amenable to integrati…
We investigate thermal energy coupling between carbon nanotubes (CNTs) and ${\text{SiO}}_{2}$ with nonequilibrium molecular dynamics simulations. The phonon thermal boundary conductance $(g)$ per CNT unit length is found to scale proportionally with the strength of the van der Waals interaction $(\ensuremath{\sim}\ens…
We demonstrate an innovative concept for nanoscale electro-optic switching. It exploits the frequency shift of a narrow-band Fano resonance mode in a plasmonic planar metamaterial induced by a change in the dielectric properties of an adjacent chalcogenide glass layer. An electrically stimulated transition between amo…

Gold nanoparticles have attracted enormous scientific and technological interest due to their ease of synthesis, chemical stability, and unique optical properties. Proof-of-concept studies demonstrate their biomedical applications in chemical sensing, biological imaging, drug delivery, and cancer treatment. Knowledge…
Electrochemical insertion-deintercalation reactions are typically associated with significant change of molar volume of the host compound. This strong coupling between ionic currents and strains underpins image formation mechanisms in electrochemical strain microscopy (ESM), and allows exploring the tip-induced electr…
Direct comparisons between statistically sound simulations of ion-tracks and published experimental measurements of range densities of iodine implants in uranium dioxide have been made with implant energies in the range of 100-800 keV. Our simulations are conducted with REED-MD (Rare Event Enhanced Domain-following Mo…
Operation of semiconductor scintillators requires optically-tight integration of the photoreceiver system on the surface of the scintillator slab. We have implemented an efficient and fast quaternary InGaAsP pin photodiode, epitaxially grown upon the surface of an InP scintillator wafer and sensitive to InP luminescen…
Abstract The removal of a surface air layer from a superhydrophobic coating in flowing water was evaluated using a laser beam and a high-speed camera. It proceeded via three steps: (1) removal of the top unstable air layer, (2) retention of air in the bottom of the surface microstructure, and (3) replacement of air in…
GlnD is a bifunctional uridylyltransferase/uridylyl-removing enzyme (UTase/UR) and is believed to be the primary sensor of nitrogen status in the cell by sensing the level of glutamine in enteric bacteria. It plays an important role in nitrogen assimilation and metabolism by reversibly regulating the modification of P…
We report the fabrication of heterostructure white light-emitting diode (LED) comprised of n-ZnO nanotubes (NTs) aqueous chemically synthesized on p-GaN substrate. Room temperature electroluminescence (EL) of the LED demonstrates strong broadband white emission spectrum consisting of predominating peak centred at 560…
This study seeks to clarify the influence of grain character on the corrosion rate of Mg. There is a special need to understand the largely unknown corrosion–grain size relationship for Mg, which nominally displays poor corrosion resistance, since any efforts to reduce or control the rate of Mg corrosion are of large…
The opportunities given by the low-frequency Raman spectroscopy for studying the ordered structures in polymers are presented and illustrated by examples of application of two techniques. The longitudinal acoustic modes (LAM) excited in straight chain segments of macromolecules are characteristic in linear semicrystal…
Fused silica slurries with a maximum ceramic loading of 70 vol% were prepared using aqueous premixes with egg white (0.5–1.5 vol%) and/or sucrose (5–20 vol%). The egg white and sucrose content in the premix were optimized to obtain a shear‐thinning slurry. Observation indicated the existence of an optimum composition…
Second-order nonlinear optical (NLO) properties of a paramagnetic all-organic chiral smectic liquid crystal have been studied. Second-harmonic generation (SHG) was clearly observed under a phase-matching condition in the ferroelectric chiral smectic C (SmC * ) phase. The effective second-order NLO constant was evaluat…
Phase transformations in microcrystalline cellulose (MCC) were studied following dissolution of 5, 10, and 20 wt. % MCC in the ionic liquid 1-butyl-3-methylimidazolium formate (BMIMFmO) and regeneration via water. BMIMFmO was found to be useful as a non-derivatizing solvent for cellulose without the need for any pre-t…
We have developed an electrochromic switchable mirror with high durability in the environment for practical applications. The structure of the new device includes an ultraviolet-cured epoxy resin and cover glass as surface coating. Although the new device has thicker films than the conventional device without surface…
Double excitonic absorption peaks are observed in textured BaCuSF and BaCuSeF thin films. The excitonic doublet separation increases with increasing fraction of heavy chalcogen in the thin-film solid solutions, in good agreement with the spin-orbit splitting of the valence bands calculated by density-functional theory…
