New materials for hydrogen storage of Li-doped fullerene (C20, C28, C36, C50, C60, C70)-intercalated hexagonal boron nitrogen (h-BN) frameworks were designed by using density functional theory (DFT) calculations. First-principles molecular dynamics (MD) simulations showed that the structures of the C n -BN (n = 20, 28…
Using a combination of first-principles calculation and high-resolution scanning TEM, the authors report novel structural characteristics of the ferreoelastic 90${}^{\ensuremath{\circ}}$ domain wall in PbTiO${}_{3}$. They highlight the discovery of a sharp discontinuity in the variation of the lattice parameters acros…
A number of LnOCuCh (Ln = La–Nd, Bi; Ch = S, Se, Te) compounds have been reported in the literature built from alternating layers of fluorite-like [Ln 2 O 2 ] 2+ sheets and antifluorite-like [M 2 Se 2 ] 2– sheets, where M is in the +1 oxidation state leading to full occupancy of available MSe 4/2 tetrahedral sites. Th…
Previous studies of polymer motion at solid/liquid interfaces described the transport in the context of a continuous time random walk (CTRW) process, in which diffusion switches between desorption-mediated “flights” (i.e., hopping) and surface-adsorbed waiting-time intervals. However, it has been unclear whether the w…
This work aims to analyze the effects of cold atmospheric air plasma treatment of antimicrobial chitosan film with different levels of thymol. Optical characterization of the dielectric barrier discharge showed the generation... | Find, read and cite all the research you need on Tech Science Press
This research paper presents the development of nonconventional actuation technology for use in a prosthetic hand. Shape-memory alloy (SMA) is used for the actuation. SMA is a material which contracts when heated and relaxes when cooled and has a work density 25 times greater than traditional electric motor actuators.…
Structures and electronic properties of TinV (n = 1-16) clusters have been investigated using density functional theory with the generalized gradient approximatio. The calculations have shown that the TinV clusters favor compact spherical structures having similar conformations to the pure Tin clusters. The results sh…
Nanoparticle-based temperature imaging is an emerging field of advanced applications. Herein, the sensitivity of the fluorescence of rhodamine B-doped latex nanoparticles toward temperature is described. Submicrometer size latex particles were prepared by a surfactant-free emulsion polymerization method that allowed a…
Amphiphilic triblock copolymers with poly(2‐methyl‐2‐oxazoline) (MeOx) end blocks and a poly(2‐ n ‐butyl‐2‐oxazoline) ( n BuOx) middle block have been found to solubilize large amounts of the cancer drug paclitaxel (PTX) whereas this is not the case when the middle block is more hydrophobic, such as poly(2‐ n ‐nonyl‐2…
We present a three-dimensional structure-map based on experimental data for compounds that contain sp -block elements and transition metals. The map predicts the correct crystal structure with a probability of 86% and has a confidence of better than 98% that the correct crystal structure is among three predicted cryst…
By the generalized gradient approximation in the framework of density functional theory, we find a new silicon allotrope (called dumbbell silicene) with high stability, which can turn a quantum spin Hall insulator with an inverted band gap through tuning external compression strain, just like in previous silicene. How…
BACKGROUND: Gadobutrol is a gadolinium-based contrast agent, uniquely formulated at 1.0 mmol/ml. Although there is extensive safety evidence on the use of gadobutrol in adults, few studies have addressed the safety and tolerability of gadobutrol in pediatric patients. OBJECTIVE: This subanalysis of data from the GARDI…
Polymorphic phase boundaries (PPBs) in piezoelectric materials have attracted significant interest in recent years, in particular, because of the unique properties that can be found in their vicinity. However, to fully harness their potential as micro-nanoscale functional entities, it is essential to achieve reliable…
Abstract Inspired by the egg‐like yolk–shell structure, a novel kind of graphene‐wrapped graphitic hollow carbon spheres (G‐graphitic HCS) was designed and fabricated by iron‐catalyzed carbonization of double‐coated polystyrene (PS) spheres. Herein, a thin carbon shell and hollow, hierarchically porous G‐graphitic HCS…
Antifouling surfaces are important for biomedical devices to prevent secondary infections and mitigate the effects of the foreign body response. Herein, we describe melt-coextruded poly(ε-caprolactone) (PCL) nanofiber mats grafted with antifouling polymers. Nonwoven PCL fiber mats are produced using a multilayered mel…
In this work, for the first time, alginate dialdehyde (AD) has been used as a cross linker to prepare casein films. The films, synthesized, have been characterized by Fourier transform infrared spectroscopy, X-ray diffraction analysis and scanning electron microscopy and thermogravimetric analysis. The films were inve…
Abstract Mono- and multilayer FeSe thin films grown on SrTiO 3 and BiTiO 3 substrates exhibit a greatly enhanced superconductivity over that found in bulk FeSe. A number of proposals have been advanced for the mechanism of this enhancement. One possibility is the introduction of a cross-interface electron–phonon (e–ph…
Solids are distinguished from fluids by their ability to resist shear. In equilibrium systems, the resistance to shear is associated with the emergence of broken translational symmetry as exhibited by a nonuniform density pattern that is persistent, which in turn results from minimizing the free energy. In this work,…
Phase-field method micromagnetic microelastic modeling is employed to simulate the thermal domain stability and enhanced magnetostrictive responses around the ferromagnetic morphotropic phase boundary (MPB) in giant magnetostrictive Tb1−xDyxFe2 (x≈0.27) single crystal. The simulation shows that the rhombohedral and te…
Two tetra-antimony(III)-bridged, sandwich-type 18-tungsto-2-arsenates(V), [(LSb(III))4(A-α-As(V)W9O34)2](10-) (L = Ph (1), OH (2)), were prepared and fully characterized in the solid state and in solution. Both polyanions are stable in aqueous physiological medium for at least 24 h (at concentrations ≥2.5 × 10(-6) M).…
