In general, optical nanomaterials composed of noncentrosymmetric nanoscatterers are bifacial, meaning that two counter-propagating waves inside the material behave differently. Thus far a practical theory for the description of such materials has been missing. Herein, we present a theory that connects the design of th…
Silanized vapor‐grown carbon nanofiber/epoxy (silanized‐VGCNF/EP) shape memory polymer (SMP) nanocomposites are successfully fabricated by using a composite molding technology. The surface functionalization of VGCNF is performed using an acid treatment followed by a reaction with silane. The oxidation as well as silan…
Under shock loadings, the temperature of materials may vary dramatically during deformation and fracture processes. Thus, thermal effect is important for constructing dynamical failure models. Existing works on thermal dissipation effects are mostly from meso- to macro-scale levels based on phenomenological assumption…
We analyze the structural, electronic, and magnetic properties of the europium chalcogenide series Eu$X$ ($X=\text{O,}\phantom{\rule{4.pt}{0ex}}\text{S,}\phantom{\rule{4.pt}{0ex}}\text{Se,}\phantom{\rule{4.pt}{0ex}}\text{and}\phantom{\rule{4.pt}{0ex}}\text{Te}$) using density-functional theory (DFT). To describe the l…

This article describes the synthesis and liquid-crystalline characterisation of four kinds of azobenzene derivatives: 1-[4-(hexyloxy)phenyl]-2-(4-X-phenyl)diazenes (A), 4-[(4-X-phenyl)diazenyl]phenyl heptanoates (B), 4-[(4-X-phenyl)diazenyl]phenyl 4-(dodecyloxy)benzoates (C) and 4-[(4-X-phenyl)diazenyl]phenyl 4-{[(2S)…
We report a dynamic analysis to simultaneously measure colloidal forces and hydrodynamic interactions in the presence of both adsorbed and unadsorbed macromolecules. A Bayesian inference method is used to self-consistently obtain the position-dependent potential energy (i.e., energy landscape) and diffusivity (i.e., d…
The Cahn-Hilliard equation was proposed as a phenomenological model for describing the process of phase separation of a binary alloy. The equation has been applied to many physical applications such as amorphological instability caused by elastic non-equilibrium, image inpainting, two- and three-phase fluid flow, phas…
Chain-extended poly(lactic acid) /clay nanocomposites were prepared through extrusion process. The effects of the content and dispersion morphology of clay on the molecular weight distribution and rheological behavior of chain extended poly(lactic acid) were discussed. The chain extender/clay ratio would strongly affe…
The Japan Aerospace Exploration Agency (JAXA) started a high-quality protein crystal growth project, now called JAXA PCG, on the International Space Station (ISS) in 2002. Using the counter-diffusion technique, 14 sessions of experiments have been performed as of 2012 with 580 proteins crystallized in total. Over the…
The evolution of elastic properties with temperature and magnetic field was studied in two differently heat-treated single crystals of the Ni-Mn-Ga magnetic shape memory alloy using resonant ultrasound spectroscopy. Quenching and slow furnace cooling were used to obtain different densities of antiphase boundaries. We…
Herbaspirillum seropedicae is a diazotrophic ß-Proteobacterium found associated with important agricultural crops. This bacterium produces polyhydroxybutyrate (PHB), an aliphatic polyester, as a carbon storage and/or source of reducing equivalents. The PHB polymer is stored as intracellular insoluble granules coated m…
Recent experiments have indicated that dopants and defects can trigger new redshifted photoluminescence (PL) peaks below the E11 peak in single-walled carbon nanotubes (SWCNTs). To understand the origin of the new PL peaks, we study theoretically the excited-state properties of SWCNTs with some typical dopants and def…
One new supramolecular structure organic-inorganic hybrid compound (3-C6H8N)4(PMo12O40)·H2O constructed by phosphomolybdate and 3-methylpyridine via hydrogen bond and π-π stacking interactions was obtained by hydrothermal reaction and characterized by IR, UV-vis, TG-DTA, FL, CV, and single-crystal X-ray diffraction. T…
Triplet-triplet annihilation photon upconversion (TTA-UC) is a promising candidate for mitigating sub-band gap absorption losses in solar cells. In TTA-UC, sensitiser dyes absorb sub-band gap photons, cross to a triplet state, and transfer triplet excitons to emitter dyes. Two triplet-excited emitters can undergo TTA,…
The electronic structure of diamane, a novel material of ultrathin hydrogenated diamond, is investigated using density-functional-theory based calculations. Focus is given on how defects and dopants can be used to tune the electronic properties of diamane films. We use boron, nitrogen, and sulfur atoms as dopants and…
Electrode materials obtained through electropolymerization of 3,4-ethylenedioxythiophene (EDOT) have sparked interest toward applications in neuroscience and neuroprosthetics due to their favorable electrochemical properties and their biocompatibility. However, insufficient mechanical stability had been an unresolved…
A novel device to produce ethyl cellulose fibres, an important biomaterial in modern food processing, using a glass needle in a modified electrospinning setup has been investigated. The effect of applied voltage on the fibre aspect ratio was analysed during electrospinning with a metallic (stainless steel) needle and…
A significant issue related to Palladium (Pd) based catalysts is that sulfur-containing species, such as alkanethiols, can form a PdSx underlayer on nanoparticle surface and subsequently poison the catalysts. Understanding the exact reaction pathway, the degree of sulfidation, the chemical stoichiometry, and the tempe…
Nanosilica/polyarylene ether nitriles terminated with phthalonitrile (SiO 2 /PEN‐ t ‐Ph) composites were prepared by hot‐press approach. To ensure the nano‐SiO 2 can disperse uniformly, the solution casting method combined with ultrasonic dispersion technology had been taken previously. The mass fraction of nano‐SiO 2…
