We introduce a strategy to generate uniform illumination. The droplet pinned by a hydrophilic/superhydrophobic heterogeneous surface is oscillated, driven by a laterally placed loudspeaker. The vibrated droplet can be considered as a tunable lens, whose focus and focus length can be real-time tuned. The tunable "lens"…
Summary In this paper, the authors propose a new method for identification of magnetizing inrush current phenomena. In general, the identification is performed using the current waveform. However, saturation of current transformers makes it impossible to obtain such a waveform. Therefore, the authors introduce an iden…
ABSTRACT Bentonite‐filled ethylene propylene diene monomer (EPDM/Bt) composites were prepared using two roll mill compounding method and the effect of Bt loading on the thermal aging, swelling resistance and crosslink density of EPDM/Bt composites were studied. The effect of in situ addition of different silane coupli…
Gaseous diffusion of diethyl ether into the solvothermal reaction mixture of copper cyanide (CuCN) with 2,2'-bipyridine (bipy) in anhydrous acetonitrile leads to a copper cyanide complex Cu(CN)(bipy) (1) with a special helical chain structure. Solid-state luminescence experiments show that complex 1 can emit efficient…
Quinary Ti–B–C–N–Si nanocomposite thin films were deposited on AISI 304 stainless steel substrates by d.c. unbalanced magnetron sputtering from a TiB2–TiC compound target and a pure Si target. The relationship between microstructure and mechanical properties of the films was investigated in terms of the nanosized crys…
Solid oxide fuel cell (SOFC) systems have been recognized as the most advanced power generation system with the highest thermal efficiency with a compatibility with a wide variety of hydrocarbon fuels, synthetic gas from coal, hydrogen, etc. As a result of research focused on numerical studies for a tubular type- or a…
Short peptide surfactants (pepfactants) bearing the amphiphilic molecular architecture of hydrophobic and hydrophilic moieties are attractive for a wide range of biological and medical applications. Understanding of structural basis and molecular mechanism underlying the self-assembling behaviour of pepfactants is fun…
Amino-terminated oligomeric poly(tetramethylene terephthalamide) (PTTA) was prepared by condensation of terephthalic acid and 1,4-diaminobutane using phosphorylation technique. Schiff base complexes of this polyamide were synthesized with salicylaldehyde and 2-hydroxy-1-naphthaldehyde complexes of Co(II), Ni(II), and…
We conducted uniaxial compressive and tensile deformation on nanocrystalline Ni at a confining pressure of 6 GPa and temperatures up to 900 °C. The determined compressive yield strength is 0.8 GPa, identical to the tensile yield strength obtained in the same deformation experiment, indicating that the Bauschinger effe…
It is well known that the violence of slow cook-off explosions can greatly exceed the comparatively mild case burst events typically observed for rapid heating. However, there have been few studies that examine the reaction violence as a function of applied heat flux that explore the dependence on heating geometry and…
A simplified model is proposed to calculate reduced self-attractive energy of a free monolayer graphene sheet due to ripples. The model admits stable periodic ripple mode of a free-standing graphene ribbon in the absence of a substrate or mechanical stress, and the predicted wavelengths are in robust agreement with ob…
An alternative derivation of Brownian motion is presented. Instead of supplementing the linearized Navier-Stokes equations with a fluctuating force, we directly assume a Gaussian action functional for solvent velocity fluctuations. Solvating a particle amounts to expelling the solvent and prescribing a boundary condit…
Behaviors of liquids in two-dimensional (2D), lyophobic nanoenvironment were investigated experimentally by using a surface-modified, graphene-based nanoslit composite (GBNC). Different from previous reports on one-dimensional (1D) nanofludic behaviors, the infiltration pressure of 2D nanofluid is not dependent on the…
We present a method to align liquid crystal (LC) samples in their SmecticA phase, useful to obtain permanent homeotropic single domains even in compounds where the nematic phase is absent. It is based on the application of a strain field, within the sample volume, which tends to align the molecules all towards a commo…
UltraScan Solution Modeler (US-SOMO) computes hydrodynamic parameters and small-angle scattering data from biological macromolecular structural representations and compares them with experimental data for structural determination and validation. At XSEDE 12, a GUI integrated gateway was introduced to offload large com…
Layered materials with a non-zero band gap have emerged in the past few years because of their potential to supersede graphene in nano-electronics. Zirconium nitrogen halides (ZrNX, X = Cl,Br) are indirect gap semiconductors with a layered crystal structure. Here, we report the realization of electric field effects in…
ZnAl2O4:Cr3+, Tb3+ powders with different dopant contents have been synthesized by sol-gel method using the following precursors: zinc nitrate (Zn(NO3)2), aluminum nitrate (Al(NO3)3), terbium nitrate (Tb(NO3)3), chrome nitrate (Cr(NO3)3), and citric acid. The effect of the Cr3+, Tb3+ concentration and heat-treating te…
Abstract The organic‐inorganic hybrid nonlinear optical (NLO) material NH4B(d‐(+)‐C4H4O5)2·H2O (NBC) was synthesized in a borate‐carboxylic acid system. Its structure was determined by single crystal X‐ray diffraction. It crystallizes in the orthorhombic system, space group Pna21 (No. 33), with cell parameters a = 11.…
Abstract Ag10Te4Br3 is the first compound of this substance class, where covalent interactions in the tellurium substructure led to the formation of Peierls distorted linear chains, responsible for a strong modulation of the electronic structure. This compound represents the first example within a series of pnp switch…
Abstract The aim of this work is to synthesize surfactants based on cellulose with different molecular weights. Raw cotton cellulose was tailored into cellulose segments with different molecular weights by a hydrothermal process, then the average degree of polymerization (DP) was determined by viscosimetry and the mol…
