Traditionally, fabric texture identification is based on visual inspection. Recent studies have proposed automatic recognition, which utilizes computer vision to recognize the texture of different fabrics. In the recognition process, the fabric weave patterns are identified by the warp and weft floats. However, due to…
Due to low charge carrier mobilities in polymer-based solar cells, device performance is dictated by the nanoscale morphology of the active layer components. However, their morphological details are notoriously difficult to distinguish due to the low electron contrast difference between the components. Phase-sensitive…
The hole mobility in thin films of $N,{N}^{\ensuremath{'}}$-diphenyl-$N,{N}^{\ensuremath{'}}$-bis(3-methylphenyl)-($1,{1}^{\ensuremath{'}}$-biphenyl)-$4,{4}^{\ensuremath{'}}$-diamine has been measured using the dark injection transient method. These measurements were performed in the presence of a small, variable offs…
Fuel cell performance is determined by the complex interplay of mass transport, energy transfer and electrochemical processes. The convolution of these processes leads to spatial heterogeneity in the way that fuel cells perform, particularly due to reactant consumption, water management and the design of fluid-flow pl…
This study presents a novel constant switching frequency band controller for dynamic voltage restorer (DVR) with a proposed filter structure. The switching operation of voltage source inverter (VSI) based on band controller, which restricts the injected voltages within a band, is explored. This control method of the V…
Abstract Poly(ether ether ketone) (PEEK) composites reinforced by short carbon fibers (SCFs) and nanoscale zirconium dioxide (ZrO 2 ) particles were prepared by twin‐screw extrusion compounding and subsequently injection molding. The effects of SCFs and ZrO 2 nanoparticles on the mechanical properties and wear behavio…
A poly(oligo(ethylene glycol) monomethyl ether methacrylate)-block-poly(N-isopropyl methacrylamide) (POEGMA-b-PNIPMAM) block copolymer with a biotin end group on the PNIPMAM block as a biotarget was synthesized as a model system for temperature-controlled polymer immobilization. The synthesis was based on RAFT polymer…
A new class of dithieno[3,2-b:2',3'-d]pyrroles (DTPs) incorporating N-acyl groups have been prepared from 3-bromothiophene via copper-catalyzed amidation. The utilization of various electron-withdrawing acyl groups has allowed stabilization of the HOMO and LUMO energy levels of these popular building blocks for conjug…
Removal of cadmium(II), lead(II), and chromium(VI) from aqueous solution using clay, a naturally occurring low-cost adsorbent, under various conditions, such as contact time, initial concentration, temperature, and pH has been investigated. The sorption of these metals follows both Langmuir and Freundlich adsorption i…
A new fluorescent sensing approach for detection of single-nucleotide polymorphisms (SNPs) is proposed based on the ligase reaction and gold nanoparticle (AuNPs)-quenched fluorescent oligonucleotides. The design exploits the strong fluorescence quenching of AuNPs for organic dyes and the difference in noncovalent inte…
Rolled-up microtubes work as catalytic striders at the air–liquid interface of hydrogen peroxide solution (sketched in the left image). Such micromachines, buoyed by oxygen bubbles, self-propel at the fuel surface by the bubble recoiling mechanism and dynamically self-assemble into patterns (right image) due to the me…
Elastic network models (ENMs) are coarse-grained descriptions of proteins as networks of coupled harmonic oscillators. However, despite their widespread application to study collective movements, there is still no consensus parametrization for the ENMs. When compared to molecular dynamics (MD) flexibility in solution,…
We consider circular currents driven by voltage bias in molecular wires with loop substructures studied within simple tight-binding models. Previous studies of this issue have focused on specific molecular structures. Here we address several general issues. First we consider the quantitative definition of a circular c…
Extensive molecular dynamics (MD) simulations of 6FDA−6FpDA, 6FDA−6FmDA, and 6FDA−DAM polyimides with CO 2 weight percentages up to ∼30%, were carried out to characterize the atomic level features associated with CO 2 diffusivity in these glassy matrices. The fluorinated polyimide models were first loaded with CO 2 in…
A three-dimensional microporous metal-organic framework, Zn(5)(BTA)(6)(TDA)(2)·15DMF·8H(2)O (1; HBTA = 1,2,3-benzenetriazole; H(2)TDA = thiophene-2,5-dicarboxylic acid), comprising pentanuclear [Zn(5)] cluster units, was obtained through an one-pot solvothermal reaction of Zn(NO(3))(2), 1,2,3-benzenetriazole, and thio…
Novel multifunctional nanoparticles that combine two functionalities (a gold nanorod core and a porphyrin-doped mesoporous silica shell) into one entity were synthesized. Due to the encapsulation of mesoporous silica, the porphyrin can be well protected against the external bioenvironment. In addition, the generated s…

Two new, homochiral, porous metal-organic coordination polymers [Zn(2)(ndc){(R)-man}(dmf)]⋅3DMF and [Zn(2)(bpdc){(R)-man}(dmf)]⋅2DMF (ndc=2,6-naphthalenedicarboxylate; bpdc=4,4'-biphenyldicarboxylate; man=mandelate; dmf=N,N'-dimethylformamide) have been synthesized by heating Zn(II) nitrate, H(2)ndc or H(2)bpdc and ch…
Thermodynamic properties of three oxides of niobium have been measured using solid state electrochemical cells incorporating yttria-doped thoria (YDT) as the electrolyte in the temperature range T = (1000 to 1300) K. The standard Gibbs energies of formation of NbO, NbO 2, and NbO 2.422 from the elements can be express…
