Recently, solid lipid nanoparticles (SLNs) have attracted increasing attention owing to their potential as an oral delivery system, promoting intestinal absorption in the lymphatic circulation which plays a role in disseminating metastatic cancer cells and infectious agents throughout the body. SLN features can be exp…
Kravtsovite, PdAg 2 S, is a new platinum-group mineral discovered in the Komsomolsky mine of the Talnakh deposit, Noril’sk district, Russia. It forms equant inclusions (ranging in size from a few μm to 40–50 μm) in silicates and pyrite, commonly intergrown with vysotskite and Au–Ag alloy in aggregates (100–200 μm acro…
Abstract Ni–Mn–Ga–Cu microwires, with diameter of 20–80 μm, length of 30–150 mm and fined columnar grains, were produced by melt‐extraction technique. The damping capacity of the extracted microwires was investigated by stretching a microwire under a tensile stress using dynamic mechanical analyzer. The damping capaci…
Zinc complexes with multidentate Schiff base ligands are suitable precursors for ZnO in microwave-assisted transformation reactions. [Bis(acetylacetonato)ethylenediimine]zinc(II) and [bis(methylacetoacetato)ethylenediimine]zinc(II) have been synthesized with high purity and good yield from the direct reaction of the r…
Torsion deformation is an effective and simple technique to tailor the mechanical properties of Mg alloys. In this study, the influences of torsion route on microstructure and mechanical properties of AZ31 rods are investigated. The maximum torsion angle is set as 180° and the two‐pass torsion at different torsion rou…
Using density functional theory combined with orbital-selective band unfolding techniques, we study the effective band structure of silicene $(3\ifmmode\times\else\texttimes\fi{}3)$/Ag(111) $(4\ifmmode\times\else\texttimes\fi{}4)$ structure. Consistent with the ARPES spectra recently obtained by [Feng et al. Proc. Nat…
Single‐crystal turbine blades of nickel‐based superalloy are directionally solidified at different withdrawal rates of 0.0017 cm s −1 –0.01 cm s −1 aiming to investigate the evolution of as‐cast microstructures. The results show that the average primary and secondary dendrite arm spacings, and , decrease with increasi…
Polarization-induced weak ferromagnetism (WFM) was demonstrated a few years back in LiNbO 3 -type compounds, MTiO 3 (M = Fe, Mn, Ni). Although the coexistence of ferroelectric polarization and ferromagnetism has been demonstrated in this rare multiferroic family before, first in bulk FeTiO 3, then in thin-film NiTiO 3…
Double-crucible cane fabrication of highly purified chalcogenide-glass was combined with multimaterial thermal fiber drawing to produce robust low-loss 0.2 NA chalcogenide fibers. Optical transmission losses were shown to be less than 1.1 dB/m at wavelengths of 1.5, 2.0 and 4.6 μm. Fiber transmission > 97% at the 1.5…
Corrosion protection of complex surface is an active area of research due to its importance to commercial applications such as electrochemical fabrication. However, conventional coatings exhibit limited conductivity, thermal stability, and durability and are thus not suitable. Recent work has shown the potential of gr…
Cobalt oxide (Co 3 O 4 ) nanoparticles have applications in nanomedicine and nanotechnology; therefore, any possible adverse effects require thorough investigation. The present study investigated the effects of Co 3 O 4 nanoparticles on four different cell lines: liver, HepG2 hepatocellular carcinoma cells; lung, A549…
The effect of dicumyl peroxide (DCPO) concentration on the polymerization kinetics of a polysilazane system has been investigated through DSC analyses. DCPO acts as polymerization initiator by activating the polyaddition of vinyl groups. The overall heat of reaction is found to be a linear function of the DCPO concent…
Infiltration processing of reticulated porous alumina ceramics (RPC) from reticulated foam manufacturing is investigated by micro computed tomography. Infiltration is carried out with colloidal alumina slurries. Successful infiltration is found to be a function of the RPCs starting microstructure and the particle size…

Laser spike annealing was applied to PS-b-PDMS diblock copolymers to induce short-time (millisecond time scale), high-temperature (300 to 700 °C) microphase segregation and directed self-assembly of sub-10 nm features. Conditions were identified that enabled uniform microphase separation in the time frame of tens of m…
Reversible switching of water-droplet adhesion on solid surfaces is of great significance for smart devices, such as microfluidics. In this work, we designed a foolproof method for fast and reversible magnet-controlled switching of water-droplet adhesion surfaces by doping iron powders in soft poly(dimethylsiloxane).…
