Abstract There is a need to develop more sensitive and cheaper flexible temperature sensors and sensor arrays. In this work, sub‐100‐nm thick polyaniline films of different thicknesses and doping content, coated on flexible PET substrates were used to study the temperature sensing behavior. The material and electrical…
We investigate structural and electronic properties of graphene-based one-dimensional (1D) superlattices by means of first-principles calculations. The 1D superlattices are modeled by three different chemical and structural modifications of the carbon lattice. We study partial hydrogenation of graphene, substitution o…
Abstract Near-field interactions in an array of electric inductive–capacitive (ELC) resonators are investigated analytically, numerically and experimentally. The measurement and simulation results show that inter-cell coupling plays an important role in determining the response of metamaterials. A quasistatic dipole–d…
Two new lanthanoid thiogermanates [Ln(dien)(2)(μ-η(1),η(2)-GeS(3)(SH))](n) {Ln = La(), Nd(); dien = diethylenetriamine} were solvothermally synthesized and structurally characterized. Both and represent the first examples of the soft Lewis basic [GeS(3)(SH)](3-) anions as tridentate bridging ligand to hard Lewis acidi…
Abstract The biocomposites composed of sorbitol polyglycidyl ether (SPE), tung oil‐pyrogallol resin (TPG), and wood flour (WF) were prepared by the compression molding at 190°C, and their thermal and mechanical properties were investigated in detail. The epoxy/hydroxy ratio was fixed to 1/1 in the curing reaction of S…
Well-defined magnetic mesoporous silica nanoparticles (MMSNs) with a core/shell structure were prepared via a one pot synthesis. Sphere-like magnetite aggregates were obtained as cores of the final nanoparticles by assembly in the presence of polyvinyl pyrrolidone and cetyltrimethylammonium bromide. The nanoparticles…

The sign and profile of the thermal Hall conductivity ${\ensuremath{\kappa}}_{xy}$ gives important insights into the gap structure of multiband superconductors. With this perspective, we have investigated ${\ensuremath{\kappa}}_{xy}$ and the thermal conductivity ${\ensuremath{\kappa}}_{xx}$ in ${\text{Ba}}_{1\ensurema…
We demonstrate that C,N-codoped InOOH microspheres could be prepared by using a facile citric acid assisted hydrothermal method at 220 °C. The citric acid could not only act as a complexing agent to control the morphology and the size, but also serve as a carbon source and a reducing agent for C and N codoping. The co…
Abstract Poly(lactic acid) ( PLA ) is a biodegradable aliphatic polyester, but its brittleness makes it unsuitable for many packaging and appliance applications. The goal of the work reported was to create novel poly(ester urethane)s that incorporate biodegradable poly(lactic acid) diols ( PLA‐OHs ) and good mechanica…
This paper presents the optically controllable light scattering based on dye-doped liquid crystals (DDLCs) in a cell, whose substrates are coated with poly(N-vinylcarbazole) (PVK) films. The optical control mechanism is the light-induced dissolution of PVK in DDLCs, which reforms the disordered LC distribution into mu…
Abstract Alumina whiskers were melt‐mixed with polyamide 12 to obtain new composites with high performance properties and similar processability of neat polyamide. Three kinds of alumina whiskers were used to prepare composites (purified fibers, ribbon‐shaped fibers and silica‐coated fibers). The rheology, morphology…

In this research, switchgrass (SG) fiber-reinforced poly(trimethylene terephthalate) (PTT) biocomposites were prepared by extrusion followed by injection molding machine. The methylene-diphenyl-diisocyanate-polybutadiene (MDIPB) prepolymer was used to enhance the impact strength of the biocomposites. In addition, the…
The present study investigates moving contact lines in microfluidic confinements with rough topographies modeled with random generating functions. Using matched asymptotic expansion, the description of the whole contact line is obtained and the dynamic contact angle is extracted by extrapolating the bulk meniscus to t…
Using highly efficient simulations of the tight-binding Bogoliubov--de-Gennes model, we solved self-consistently for the pair correlation and the Josephson current in a superconducting-bilayer graphene--superconducting Josephson junction. Different doping levels for the non-superconducting link are considered in the s…
Polycationic polymers are used extensively in biology to disrupt cell membranes and thus enhance the transport of materials into the cell. We report the bindings of several lipids cholesterol (Chol), 1,2-dioleoyl-3-trimethylammonium-propane(DOTAP), dioctadecyldimethylammoniumbromide (DDAB), and dioleoylphosphatidyleth…
Understanding the growth process of nanomaterials enables the control of their sizes/morphologies to enhance their performance for a given application. Herein we report the investigation into the synthesis of Ag2S nanocrystals by reacting Ag+ ions and/or Ag nanoparticles with S powder in a nonpolar organic solvent. Th…
An anode-supported cone-shaped tubular solid oxide fuel cell (SOFC) with (Ni 0.75 Fe 0.25 -5%MgO)/YSZ anode is prepared and is directly operated on dry and moist CO fuel, respectively. At 800°C, the cell exhibits a maximum power density (MPD) of 424 mWcm −2 for dry CO and 388 mWcm −2 for moist CO. The durability test…
The catalytic activities, to the reduction of SO 2 by CO, of clusters Pt l Au m ( l + m = 2) with or without preadsorbing CO molecules are investigated using first-principles density functional theory. We find that the PtAu(CO) n ( n = 1–3) clusters show more excellent catalytic properties than either pure metallic ca…
