Abstract Two kinds of W/Cu double‐layer shaped charge liner (SCL) were prepared by chemical vapor deposition (CVD) combined with electroforming technique: A SCL with W inner layer and Cu outer layer, B SCL with Cu inner layer and W outer layer. The penetration properties of A and B SCLs were researched. The results sh…
Lead bismuth titanate borosilicate glasses were prepared in the glass system 65[( PbxBi1-x )·TiO3]-34[2SiO2·B2O3]-1La2O3( 0.0≤x≤1.0 ) doped with one mole percent of La2O3 via conventional melt quench method. The amorphous nature of glass samples in this glass system is confirmed by using X-ray diffraction (XRD) study.…
Direct synthesis of high-quality doped graphene on dielectric substrates without transfer is highly desired for simplified device processing in electronic applications. However, graphene synthesis directly on substrates suitable for device applications, though highly demanded, remains unattainable and challenging. Her…
The revolutionary development of nanoscience during the last years has increased the number of studies in the field to evaluate the toxicity and risk levels. The design of different nanomaterials together with biological components has implemented the advances in biomedicine. Specifically, nanoparticles seem to be a p…
ABSTRACT Accelerated aging tests are the conventional way to evaluate long‐term degradation of polymers, in particular for offshore flexible risers. In this article, a multiscale model has been developed combining diffusion, chemical kinetic reactions, structure–property relationships, and composite models to provide…
Polymericaly modified clays that contain an oligomeric poly(styrene‐ co ‐chloromethyl styrene) ammonium salt have been prepared and used to preparation of polystyrene (PS) nanocomposites. First, PS and poly(styrene‐co‐chloromethyl styrene) [P(St‐co‐CMSt)] were synthesized by nitroxide mediated living free radical poly…
Abstract Mo0, W0, Fe0, Ru0, Re0, and Zn0 nanoparticles—essentially base metals—are prepared as a general strategy by a sodium naphthalenide ([NaNaph])‐driven reduction of simple metal chlorides in ethers (1,2‐dimethoxyethane (DME), tetrahydrofuran (THF)). All the nanoparticles have diameters ≤10 nm, and they can be ob…
We demonstrate the existence of metamaterial blueprints describing, and fundamental limitations concerning, perfectly reflectionless omnidirectional electromagnetic absorbers (PR-OEMAs). Previous attempts to define PR-OEMA blueprints have led to active (gain), rather than passive, media. We explain this fact and unvei…
An automated geometric characterization tool for woven textiles is presented. This tool is used to obtain the in-plane geometry of woven textiles in a fast and efficient method. These measurements can be used to provide a better understanding of the textile geometry and can be used in further applications such as qual…
Hydrophobic films were synthesized with a variety of silica particle sizes ranging from 58 to 1428 nm to investigate the effect of particle size on the contact and sliding angles. While the surface roughness created by varying the particle size did not appear to affect water contact angles, the sliding angles showed a…
A range of compelling information on the local structure and dynamics of the ferroelectric perovskite-type $({\mathrm{ABO}}_{3})$ system $(1\ensuremath{-}x){\mathrm{PbTiO}}_{3}\ensuremath{-}x{\mathrm{BiScO}}_{3}$ has been revealed through analyzing room-temperature x-ray pair distribution functions and temperature-dep…
Stimulated scattering in gold-nanorod-water samples has been investigated experimentally. The scattering centers are impurity particles rather than the atoms or molecules of conventional homogeneous scattering media. The pump source for exciting stimulated scattering is a pulsed and narrow linewidth second-harmonic Nd…
Engineered nanomaterials (ENMs) are being produced at an increasing rate. Because of their unique physicochemical properties, ENMs have been used in a wide variety of commercial products. The specific properties of ENMs, such as their relatively larger surface area, however, could also cause adverse biological effects…
One of the most critical events in the origins of cellular life was the development of lipid membranes. Archaea use isoprenoid chains linked via ether bonds to sn-glycerol 1-phosphate (G1P), whereas bacteria and eukaryotes use fatty acids attached via ester bonds to enantiomeric sn-glycerol 3-phosphate. NAD(P)H-depend…
There is growing interest in fabricating conventional semiconductor devices in a nanofilm which could be a 3D material with one reduced dimension (e.g., silicon-on-insulator (SOI) film), or single/multiple layers of a 2D material (e.g., MoS2), or a two dimensional electron gas/two dimensional hole gas (2DEG/2DHG) laye…
The purpose of this study was to develop quantitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for the analysis of proteins involved in metastasis of breast cancer for diagnosis and determining disease prognosis, as well as to further our understand of metastatic mechanisms. We have previously…
Four different manufactured surface-coated silver nanoparticles (AgNPs) with coating of citrate, tannic acid, polyethylene glycol, and branched polyethylenimine were used in this study. The toxicity of surface-coated AgNPs was evaluated by a luminous microbial array for toxicity risk assessment (LumiMARA) using multi-…
Abstract A lanthanum and calcium co‐doped A‐site deficient strontium titanate (LSCTA–) was used as alternative anode material in Solid Oxide Fuel Cells (SOFC) with an active area of 100 cm2. Cell performance was tested in both short (5 cell) stack configuration, as well as a full HEXIS Galileo system (nominally 1 kW A…
The hydrolytes soy protein isolates (HSPI)-modified urea–formaldehyde (UF) resins were synthesized via copolymerization process. The best bonding strength is 1.50 MPa and improves 51.5% compared with pure UF. In addition, the formaldehyde emission decreased. The effect of (HSPI) on the biodegradable (UF) resins was in…
Lattice vibrations and electrical transport properties of SrV2O6 (SVO) and BaV2O6 (BVO) under high pressure have been investigated by Raman spectra and alternating current (AC) impedance spectra measurements. A pressure-induced structural phase transition in SVO is observed at 3.9 GPa, and the phase transition in BVO…
