A one-step and energy-saving method was proposed to synthesize hierarchical and hollow Co(VO 3 ) 2 -Co(OH) 2 composite leaf arrays on carbon cloth, which expressed high capacitance (522 mF cm –2 or 803 F g –1 at the current density of 0.5 mA cm –2 ), good rate capability (79.5% capacitance retention after a 30-fold in…
The aim of the present study was to investigate the modeling and prediction of the high temperature flow characteristics of a cast magnesium (Mg–Al–Ca) alloy by both constitutive equation and ANN model. Toward this end, hot compression experiments were performed in 250–450 °C and in strain rates of 0.001–1 s−1. The tr…
The Y 3 Al 2 Ga 3 O 12:Ce 3+ –Cr 3+ compound is one of the brightest persistent phosphors, but its persistent luminescence duration is not so long because of the relatively shallow Cr 3+ electron trap. To compare the vacuum referred binding energy of the electron trapping state by Cr 3+ and lanthanide ions, we selecte…
Auto-associative neural networks ("autoencoders") present a powerful nonlinear dimensionality reduction technique to mine data-driven collective variables from molecular simulation trajectories. This technique furnishes explicit and differentiable expressions for the nonlinear collective variables, making it ideally s…
Ligand-induced chirality in semiconductor nanocrystals (NCs) has attracted attention because of the tunable optical properties of the NCs. Induced circular dichroism (CD) has been observed in CdX (X = S, Se, Te) NCs and their hybrids, but circularly polarized luminescence (CPL) in these fluorescent nanomaterials has b…
Fast-growth of single crystal monolayer graphene by CVD using methane and hydrogen has been achieved on “homemade” single crystal Cu/Ni(111) alloy foils over large area. Full coverage was achieved in 5 min or less for a particular range of composition (1.3 at.% to 8.6 at.% Ni), as compared to 60 min for a pure Cu(111)…
Generally, certain parts of aircraft and weapons, for example, head cone, engine inlet and nozzle, need to be resistant to high-temperature and high-speed heat flow. In order to meet the requirement of stealth of these special parts, the high-temperature structural absorbing materials, for example, ceramic fibers, cer…
Abstract The mechanical behavior of high quality two-dimensional (2D) crystals offers exciting opportunities for new material design, such as the combination of extremely high in-plane stiffness and bending flexibility, compared to existing three-dimensional (3D) material forms. By combining different 2D crystals vert…
Melanins are well-known biopolymers that are ubiquitous in nature, distributed widely in microorganisms, plants, and animals, and play significant physiological roles. They are mostly biopolymers formed from phenolic compounds by polymerization via quinones. Poly(dopamine) (PDA), a melanin-like material, is similar in…
Abstract Red-emitting Mn 4+ -doped fluorides are a promising class of materials to improve the color rendering and luminous efficacy of white light-emitting diodes (w-LEDs). For w-LEDs, the luminescence quenching temperature is very important, but surprisingly no systematic research has been conducted to understand th…
Background: Paclitaxel (PTX) is a potent anticancer drug which is highly effective against several cancers. Solid lipid nanoparticles (SLNs) loaded with anticancer drugs can enhance its toxicity against tumor cells at low concentrations. Objective: To develop and characterize SLNs of PTX (PSLN) to enhance its toxicity…
David F. Estera & Vance E. Williams*aa Department of Chemistry, Simon Fraser University, Burnaby, CanadaCONTACT Vance E. Williams vancew@sfu.caABSTRACTIn an effort to control the phase ranges of highly ordered smectic phases, we examined the impact of molecular symmetry on phase behaviour of a series of 12 symmetrical…
Abstract The effect of the concentration of carbon nanofibers (CNFs) on thermoplastic elastomer based on polypropylene/polybutadiene (PP/BR) blend (80/20) prepared by melt blending process was investigated. The morphological properties are reported in combination with the mechanical and rheological properties of the n…
Abstract Doping has become crucial for achieving stable and high-performance conductive transparent carbon nanotube (CNT) films. In this study, we systematically investigate the doping effects of a few materials including alkali metal iodides, nonmetal iodide, and metals. We demonstrate that photonic curing can enhanc…
Herein we introduce a smart Pickering emulsion fluid system, in which associative magnetic nanoparticles (AMNPs) are assembled at the oil–water interface to give magnetic‐responsiveness to the emulsion drops. AMNPs are synthesized by grafting hydrophobically modified water‐soluble poly(2‐methacryloyloxyethylphosphoryl…
The endothelialization of synthetic surfaces applied as cardiovascular implant materials is an important issue to ensure the anti-thrombotic quality of a biomaterial. However, the rapid and constant development of a functionally-confluent endothelial cell monolayer is challenging. In order to investigate the compatibi…
Abstract In the study, a hollow boron-doped diamond (BDD) nanostructure electrode is fabricated to increase the reactive surface area for electrochemical applications. Tungsten oxide nanorods are deposited on the silicon substrate as a template by the hot filament chemical vapor deposition (HFCVD) method. The template…
Abstract Die schwache Photolumineszenz von Silber‐Nanoclustern verhindert ihre breite Anwendung als lumineszenter Nanowerkstoff. In jüngerer Zeit haben Experimente jedoch gezeigt, dass eine Au‐Dotierung die Intensität der Photolumineszenz von Ag 29 ‐Nanoclustern signifikant verstärken kann, wobei die molekularen und p…
In this communication, we assembled ordered polystyrene (PS) microsphere array as a template with the drop-coating method, and the oxygen plasma was used to etch the template to adjust the spacing between the PS microspheres. Nano-triangular gold array and silver nano-pyramid array were obtained by ion beam sputtering…
In this work, Mg was employed as a starting material. Ni, Fe and Ti were selected as additives to improve hydriding and dehydriding rates of Mg. A 90 wt.% Mg + 5 wt.% Ni + 2.5 wt.% Fe + 2.5 wt.% Ti sample [named 90Mg-Ni-Fe-Ti (8 h)] was prepared by mechanical grinding under H2 atmosphere (reactive mechanical grinding)…
