A new type of ordered mesoporous carbon/polyaniline (OMCx/PANI) composite with a hexagonally ordered mesostructure was prepared by a two-step nanocasting method using SBA-15 as a template. This method could protect the pore structure of OMCx from being blocked by PANI, and the in situ polymerization of aniline inside…
The problem of stability of the polymer rod in creeping was solved by energy method in the form of Timoshenko and Ritz. Possible displacements of the points were given in the form of a trigonometric series with undetermined coefficients. Results obtained numerically using complex Matlab under different constraint equa…
Functionalized carbon nanotubes (CNTs) constitute a new class of nanostructured materials that have vast applications in CNT purification and separation, biosensing, drug delivery, etc. Hybrids formed from the functionalization of CNT with biological molecules have shown interesting properties and have attracted great…
ABSTRACT High tensile strength fibers of poly[(R)‐3‐hydroxybutyrate‐co‐(R)‐3‐hydroxyhexanoate] [P(3HB‐co‐3HH)], a type of microbial polyesters, were processed by one‐step and two‐step cold‐drawn method with intermediate annealing. Thermal degradation behaviors were characterized by differential scanning calorimeter an…
Long and narrow slit-shaped pores are predicted to have enhanced permeation and selectivity. We report, for the first time, the efficient production of membranes containing densely packed slitted pores with a pore width of <15 nm from block copolymers (BCPs). Such membranes exhibit sharp selectivity and ultrahigh wate…
Shape-selective ZnO nanoparticles (NPs) with various morphologies have been synthesized within 2 min of microwave heating by the reaction of Zn(NO 3 ) 2 ·2H 2 O with NaOH in the presence of DNA. The size and shape of the materials can be tuned by controlling the molar ratio of Zn(II) salt to DNA and by altering the ot…
In this study, a simple capillary-based approach for producing biconcave polymeric microlenses with uniform size and shape from ternary emulsion droplets is presented. Monodisperse ternary emulsion droplets (0.6-4.0 nL) are produced which contain a photocurable segment of an acrylate monomer and two non-curable segmen…
The assembly of low‐fouling polymer capsules with redox‐responsive behavior and intracellular degradability is reported. Thiol‐containing poly(2‐ethyl‐2‐oxazoline) (PEtOxMASH) brushes are synthesized by atom transfer radical polymerization (ATRP) of oligo(2‐ethyl‐2‐oxazoline)methacrylate and glycidyl methacrylate (GMA…
Due to complication factors such as blood-brain barrier (BBB), integrating high efficiency of brain target ability with specific cargo releasing into one nanocarrier seems more important. A brain targeting nanoscale system is developed using dehydroascorbic acid (DHA) as targeting moiety. DHA has high affinity with GL…
A new electric double percolation was realized via carbon black self-networking induced co-continuous like morphology (composed of disconnected PU clusters and bands) in polylactide/poly(ether)urethane (PLA/PU) blends. As a result, a simultaneous improvement in electrical conductivity and impact toughness of the blend…
The ${180}^{\ensuremath{\circ}}$ ferroelectric domain walls (FDWs) have long been regarded as purely Ising type in ferroelectrics, but recent theoretical works suggested that they can also have N\'eel- and/or Bloch-like rotations. Using a combination of first-principles calculations with phase-field simulations, we st…
An ultrastable [Ag55(MoO4)6](43+) ({Ag55Mo6} for short) nanocluster with a Ag-centered multishell structure in compound [Ag55(MoO4)6(C≡C(t)Bu)24(CH3COO)18](OAc)·2H2O (1) has been obtained. The ultrastability of 1 was demonstrated by Mulliken population analysis. In addition, the potential wide gap semiconductor proper…
The Gcn5-related N-acetyltransferases (GNATs) are ubiquitously expressed in nature and perform a diverse range of cellular functions through the acetylation of small molecules and protein substrates. Using activated acetyl coenzyme A as a common acetyl donor, GNATs catalyse the transfer of an acetyl group to acceptor…
Semiconducting higher manganese silicides (HMS), with a nominal composition of MnSi 1.73, are particularly promising thermoelectric materials because of their elemental abundance, nontoxicity, and reported ZT of around 0.4 at 800 K for undoped samples. However, embedded MnSi impurities naturally form during the melt g…
Au-Cu2 O core-shell nanocubes, octahedra, and rhombic dodecahedra display facet-dependent optical properties. Furthermore, different-sized Au-Cu2 O octahedra with 58, 65, 68, and 73 nm octahedral gold cores clearly show a transition from the shell thickness-independent gold surface plasmon resonance band for octahedra…
Highly flexible, transparent, and luminescent nanofibrillated cellulose (NFC) nanopaper with heterogeneous network, functionalized by rare-earth up-converting luminescent nanoparticles (UCNPs), was rapidly synthesized by using a moderate pressure extrusion paper-making process. NFC was successfully prepared from garli…
Multi-body dynamics is a powerful engineering tool which is becoming increasingly popular for the simulation and analysis of skull biomechanics. This paper presents the first application of multi-body dynamics to analyse the biomechanics of the rabbit skull. A model has been constructed through the combination of manu…
ABSTRACT Polypropylene/jute fiber (PP‐J) composites with various concentrations of viscose fibers (VF) as impact modifiers and maleated polypropylene (MAPP) as a compatibilizer have been studied. The composite materials were manufactured using direct long fiber thermoplastic (D‐LFT) extrusion and compression molding.…
The vanadate conversion coating (VCC) was formed on the surface of magnesium (Mg) alloy in vanadium phosphate solution, as well as the cathode electrophoresis and bake-curing treatments of the conversion coating proceeded. According to the addition of vanadate in the solution, the conversion coating is refined crystal…
In this study, we present atomistic mechanisms of 1/2 [111](11¯0) edge dislocation interactions with point defects (hydrogen and vacancies) and hydrogen solute atmospheres in body centered cubic (bcc) iron. In metals such as iron, increases in hydrogen concentration can increase dislocation mobility and/or cleavage-ty…
