Explosive welding technology has been widely used in industrial production. However, there is always a controversy on the mechanism of explosive bonding, whether explosive welding should belong to a kind of mature welding such as a fusion welding or a solid phase welding. Based on the observation and analysis of the m…
Abstract Five rare earth complexes are first introduced to catalyze ring opening polymerizations (ROPs) of γ‐benzyl‐ L ‐glutamate N ‐carboxyanhydride (BLG NCA) and L ‐alanine NCA (ALA NCA) including rare earth isopropoxide (RE(OiPr) 3 ), rare earth tris(2,6‐di‐ tert ‐butyl‐4‐methylphenolate) (RE(OAr) 3 ), rare earth t…
The change in electronic structure of V${}_{1\ensuremath{-}x}$W${}_{x}$O${}_{2}$ thin films across a metal-insulator transition (MIT) is investigated in terms of hard x-ray photoemission spectroscopy and x-ray absorption spectroscopy. In the lower doping range (0 $\ensuremath{\le}$ $x$ $\ensuremath{\le}$ 0.08), the sp…
A novel liquid monomer (DOPO–VTS) containing 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO) and silicon was synthesized by allowing DOPO to react with vinyltrimethoxysilane (VTS). The DOPO-based organic/inorganic hybrid materials were prepared by the sol–gel and UV-curing methods. The scanning electron micr…
Abstract A novel charring agent, namely triazine‐based macromolecule (TBM), was synthesized via solution polycondensation of cyanuric chloride, ethanolamine, and diethylenetriamine. The prepared charring agent possessed little water solubility and superior char‐forming ability, and it showed good synergistic effects w…
A series of new poly[N-(2-hydroxypropyl)methacrylamide]-based amphiphilic copolymers were synthesized through a radical copolymerization of a monomeric/hydrophobic fluorophore possessing aggregation-induced emission (AIE) property with N-(2-hydroxypropyl)methacrylamide. Photophysical properties were investigated using…
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. New diagnostic and therapeutic strategies are needed to mitigate this public health issue. Advances in nanotechnology have generated innovative strategies for diagnosis and therapy in a variety of diseases, foremost in cancer. Base…
Manganese-carrier magnetic exchange interactions in strongly quantum-confined Mn${}^{2+}$-doped CdSe quantum dots (QDs) having ${d}_{\mathrm{QD}}$ $=$ 1.52, 2.08, and 2.54 nm have been investigated using a combination of density functional theory (DFT) and perturbation theory calculations. Established perturbation exp…
Abstract Biodegradable polymers are good candidates for a wide range of applications in tissue engineering and drug delivery because of their biocompatibility, their degradation, mechanical properties, and offer a sustained release of encapsulated drugs. The electrospun polymer nanofibrous materials can be used as car…
Magnetic polarons have been proposed to play important roles in doped wide band gap oxides that exhibit weak room temperature ferromagnetism. Here, we report the experimental evidence supporting polaronic magnetism and transport in Ag-doped ZnO. Temperature dependent resistivity data suggest the conduction mechanism o…
We experimentally demonstrated a polarization dependent state to polarization independent state change in terahertz (THz) metamaterials. This is accomplished by reconfiguring the lattice structure of metamaterials from 2-fold to 4-fold rotational symmetry by using micromachined actuators. In experiment, it measures re…
Composite coatings with hydroxyapatite (HA), octacalcium phosphate (OCP) in electrochemical deposition (ED) layers and MgO, Mg3 (PO4 )2 in microarc oxidation (MAO) layers were prepared by ED and MAO on Mg-Zn-Ca alloy to improve the corrosion resistance and bone response. Substrates and coated samples were implanted in…
Abstract Hybrid materials of Fe 3 O 4 ‐decorated reduced graphene oxide (Fe 3 O 4 ‐RGO) and poly(3,4‐ethylenedioxythiophene) (PEDOT) were prepared by poly(ionic liquid)‐mediated hybridization. In this hybrid material, poly(ionic liquid) was found to perform multiple roles for: (1) stabilizing Fe 3 O 4 ‐RGO against agg…
Boron carbide undergoes an amorphization transition under high-velocity impacts, causing it to suffer a catastrophic loss in strength. The failure mechanism is not clear and this limits the ways to improve its resistance to impact. To help uncover the failure mechanism, we used ab initio methods to carry out large-sca…

We present all-electron ${G}_{0}{W}_{0}$ calculations for the electronic structure of the organic semiconductor copper phthalocyanine, based on semilocal and hybrid density-functional theory (DFT) starting points. We show that ${G}_{0}{W}_{0}$ calculations improve the quantitative agreement with high resolution photoe…
A study was conducted on the puncture resistance of high-strength nonwoven natural rubber latex (NRL)-coated fabrics. High strength unidirectional (UD) polyethylene fabrics were coated using single dipping (SD), double dipping (DD), and triple dipping (TD) methods. The puncture resistance of the uncoated and coated fa…
High resolution powder x-ray diffraction patterns of Na0.5Bi0.5TiO3 at selected temperatures were examined to compare structural changes with observed piezoelectric thermal depoling temperatures. The depoling temperatures do not correlate with discrete phase transition temperatures, and therefore, a structural transit…
We report an experimental and theoretical lattice dynamics study of antimony telluride (Sb${}_{2}$Te${}_{3}$) up to 26 GPa together with a theoretical study of its structural stability under pressure. Raman-active modes of the low-pressure rhombohedral (R-3m) phase were observed up to 7.7 GPa. Changes of the frequenci…
