Dozens of three- and four-ring liquid crystal derivatives of alkylcyclohexyltolanes, alkylbicyclohexyltolanes and alkylbicyclohexylbiphenyls with a terminal polar group F or trifluoromethoxy (OCF3), cyano (CN), isothiocyanato (NCS) have been synthesised. Their dielectric properties upon temperature and electric field…
This paper presents the tensile behaviors of polytetrafluoroethylene (PTFE)-coated fabrics subjected to monotonous and cyclic loading. First, uniaxial tensile tests are conducted to study the uniaxial cyclic behaviors, in which the effects of stress amplitude and temperature on the fabrics are studied. Then, biaxial t…
Types of fabric movement inside a front-loading washer were analyzed in order to examine their effect on washing performance. A high-speed camera was used to record and track the outlines of the fabric inside a washer, and 13 movement indexes were derived. From this observation, fabric movements were divided into four…
This paper reports the development of a hexagon resistance model, based on the loop structure of a plain weft knitted fabric. This model is capable of describing the electromechanical properties of conductive knitted elastic fabrics. Based on the relationship between the resistance and the load on the fabric under bia…
To bridge physical mixing to chemical bonding? Use an electron beam! Individual carbon nanofibers can grow from physical mixing of amorphous carbon and Ce0.8Gd0.2O1.9/Ni nanoparticles, under an electron beam in a 300 kV transmission electron microscope, without any gaseous carbon source and external heating, as a cons…
Gold catalysts have been prepared by sol immobilization using Tetrakis(hydroxymethyl) phosphonium chloride (THPC) as a protective and reducing agent or by deposition on different supports (Al₂O₃, TiO₂, MgAl₂O₄, and MgO). The catalytic systems have been tested in the liquid phase oxidation of aminoalcohols (serinol and…
We theoretically study the spin fluctuation and superconductivity in La1111 and Sm1111 iron-based superconductors for a wide range of electron doping. When we take into account the band structure variation by electron doping, the hole Fermi surface originating from the $d_{X^2-Y^2}$ orbital turns out to be robust agai…
Abstract The synthesis and structural, mass spectrometric, FT‐IR, Mössbauer, and UV/Vis spectroscopic, electrochemical, and DC and AC magnetic properties of three [MnIII6FeIII]3+ (short for [{(talen )MnIII3}2{FeIII(CN)6}]3+) compounds {[MnIII6FeIII(MeOH)6]Cl3·11MeOH·H2O (1a), [MnIII6FeIII(MeOH)6]Cl3·3MeOH·H2O (1b), an…
The palladium–iron–arsenides Ca10(Fe1− x Pd x As)10(Pd3As8) were synthesized by solid-state methods and characterized by X-ray powder and single crystal diffraction. The triclinic crystal structure (space group P ) is isotypic to the homologue platinum 1038-type superconductors with alternating FeAs4/4- and Pd3As8-lay…
Molecular-dynamics simulations have been carried out for a coarse-grained model of a random AB-copolymer confined between two crystalline substrates. The strength of substrate-polymer interactions, and the distance between the two substrates have been varied in a wide range. For thick films the film-averaged segmental…
The haloacid dehalogenase enzyme superfamily (HADSF) is largely composed of phosphatases that have been particularly successful at adaptating to novel biological functions relative to members of other phosphatase families. Herein, we examine the structural basis for the divergence of function in two bacterial homologu…
The nature of nanocrystalline materials determines that their deformation at the grain level relies on the orientation of individual grains. In this work, we investigate the anisotropic response of nanotwinned Cu to frictional contacts during nanoscratching by means of molecular dynamics simulations. Nanotwinned Cu sa…
A new way to induce a large magnetoresistance has been achieved by self-assembled nanostructures consisting of ferromagnetic spinel CoFe₂O₄ (CFO) and metallic perovskite SrRuO₃ (SRO). The interdiffused Fe³⁺ ions in SRO have paved the way to strong magnetic couplings with CFO nanopillars, resulting in the suppression o…
Here, we report a new and facile method to prepare silver nanoparticles (Ag NPs) film for surface-enhanced Raman scattering (SERS)-based sensing. The porous Ni foam was used as a template to generate high quality of Ag NPs by seed-mediated growth of metallic nanoparticles. The preparation process is very economic and…
First‐principles method is used to study the native point defects in Y 2 SiO 5 and Y 2 Si 2 O 7 silicates. The calculated defect formulation energies show similar native point defect behaviors in Y 2 SiO 5 and Y 2 Si 2 O 7 : the oxygen Frenkel defect is predominant; and it is followed by the cation antisite and Schott…
The self-assembly of poly(ethylidene acetate) (st-PEA) into van der Waals-stabilized liquid-crystalline (LC) aggregates is reported. The LC behavior of these materials is unexpected, and unusual for flexible sp(3)-carbon backbone polymers. Although the dense packing of polar ester functionalities along the carbon back…
We investigate the superconductivity in two-dimensional electron systems formed in SrTiO3 nanostructures. Our the- oretical analysis is based on the three-orbital model, which takes into account t2g orbitals of Ti ions. Because of the interfacial breaking of mirror symmetry, a Rashba-type antisymmetric spin-orbit coup…
Surface modification of biomedical magnesium alloy using composite coating shows an attemptable approach for the development of Mg-based biomaterials with excellent cytocompatibility. Hydroxyapatite/collagen composite was preliminarily fabricated by biomineralization, the bioactive poly(l-lactic acid)/hydroxyapatite/c…
Self-assembly of discotic molecules into supramolecular polymers offers a flexible approach for the generation of multicomponent one-dimensional columnar architectures with tuneable biomedical properties. Decoration with ligands induces specific binding of the self-assembled scaffold to biological targets. The modular…
Smooth, transparent, and extremely hard zirconia (ZrO2)-based inorganic-organic hybrid films showing excellent dynamic oleophobicity, thermal durability, and hydrolytic stability were successfully prepared through a simple combination of zirconium tetrapropoxide (Zr(O(CH2)2CH3)4) with stearic acids. In this study, we…
