The thermal properties such the coefficient thermal expansion, α (CTE) of fused borosilicate syntactic foam was determined using dimensional changes of a temperature gradient plot. The CTE was measured and found to be achieved the value lower than the vinyl ester resin matrix when mixing with different weight percenta…
In this work, the van der Waal heterostructures (vdWHs) based on blue phosphorus (blue-P) and ZnO were investigated in terms of structural stability and optical properties. Two vdWHs, that are (4,6)-tetragoanl-ZnO/blue-P (46tet-ZnO/blue-P) and hexagonal-ZnO/blue-P (hex-ZnO/blue-P), were investigated using the density…
This study attempts to improve the adhesion and conductivity of polyaniline (PAni) by incorporating an alkyd and titanium dioxide (TiO2), respectively. PAni with different TiO2 content (10, 20, and 40%) are synthesized through chemical oxidation method by using aniline (Ani) monomer, dioctyl sodium sulfosuccinate (AOT…
Molecular dynamic and mesoscopic simulations are used to predict the morphologies of PS-b-PI diblock copolymer. Flory-Huggins interaction parameter is an intermediate parameter used to connect between both simulations. The repulsions between different beads are one of essential parameters that were calculated from the…
Abstract Open‐cell structures like open‐pore foams have several applications, e.g. as acoustic damping material in civil engineering. Most models for such materials capture the static but not the dynamic behavior correctly. In order to develop a model which is able to describe the static and the dynamic properties, an…
A new form of the linear augmented cylindrical wave method is proposed. For the construction of basis functions, the electron potential is taken to be spherically symmetric in atomic regions, constant in the intermediate region and cylindrically symmetric in the vacuum regions. The basis functions of the method, obtai…
Abstract A cobalt coordination polymer having the formula of [Co(npa)(L1)(H2O)2]n (1), where L1 is a bis(4-(1H-imidazol-1-yl)phenyl)methanone and H2npa is a 4-nitrophthalic acid, has been synthesized and structurally characterized. Single crystal X-ray diffraction analysis shows that the Co1 has a distorted octahedral…
The effect of the synthesized zinc oxide nanoparticles (sZnO) and calcium carbonate nanoparticles (NCC) on the cure characteristics and mechanical properties of natural rubber were investigated. The sZnO synthesized by microwave assisted aqueous precipitation method using zinc nitrate hexahydrate and sodium hydroxide…
Abstract Interaction between Li, Na, and K atoms and autonomous silicene is investigated using the density functional theory. The energies of adsorption and bond distances of Si–Me for different positions of adsorbed alkali-metal atoms are calculated. The band structure of the silicene–Me systems in a generalized grad…
Abstract— A method for determining the temperature dependences of the lattice parameters of ferroelectrics in the presence of two successive structural m3m–4mm–mm2 phase transitions, provided that the paraelectric-phase macrosymmetry is preserved in a polydomain crystal, has been proposed. Three analytical solutions f…
The most of superconductors are highly anisotropic superconductors, then the measurement on the superfluid density properties of superconductors are complicated and depended on directions. In this study, the superfluid density of anisotropic superconductors was studied by semiclassical approach. We are interested in t…
In article number 1802745, Yong-Qiang Li and co-workers report a robust tumor microenvironment-responsive theranostic nanoprobe (NanoFlare). By virtue of its anisotropic oligonucleotides-spike nanostructure, the NanoFlare can enter tumor cells universally regardless of cell type and produce a redox-activated fluoresce…
In article number 1803471, Johnas Eklöf-Österberg, Kasper Moth-Poulsen, and co-workers make isolation, positioning, and electronic measurements on single molecules possible using a combined top-down and bottom-up strategy. Proto-devices, which are self-assembled nanogaps composed of two gold nanoparticles linked by a…
Abstract Based on the data analysis of ultrasonic experiments, a novel approach has been developed to explore Jahn-Teller effect (JTE) problems in non-cubic crystals with JT centers without involving additional experimental data beyond the information about the electronic term and crystal symmetry. Distinguished from…

Abstract Iron complex‐catalyzed dehydrogenative Sn–E (E = S, Se) bond formation of hydrostannane with thiol and selenol was achieved. All new compounds were fully characterized using 1H, 13C{1H}, 77Se{1H}, and 119Sn{1H} NMR measurements and elemental analyses. The structure of 1,1′‐(1,3‐dithia‐2,2‐dibutylstanyl)‐[3]fe…
In article number 1802674, Han Young Woo, Bumjoon J. Kim and co-workers report a water-ethanol process for eco-friendly fabrication of polymer electronic devices. The authors discover that water-ethanol co-solvents remarkably improve the solubility of the oligoethylene glycol side chain-based electroactive materials,…
Fine aggregate considered as the oldest building materials known by human, it's not inert substance, so that each of its physical and chemical properties need theoretical and laboratory studies, because, of its effect on the compressive strength and durability of concrete, one of the most important properties is the c…
The transition region in worn surface of a 2.86 wt%Cr iron alloy was investigated under dry impact wear test , and apparatus consist of repeated impact of a pin specimen on a rotating grinding wheel with abrasive. Results show a convex surface is formed in transition region, and its altitude reaches maximum after 6000…
