This paper describes a simple method of making an optically transparent super-hydrophobic PDMS thin film by using a reusable photo-curable polymer mold. A photoresist mold is prepared using underexposed and under-baked positive photoresist (PR), which create unique hierarchical micro/nano structures. The reverse image…
This work reports a novel stretchable thin-film generator based on electrification for effectively harvesting body motion energy. It has two working modes, the folding mode and the contact-separation (C-S) mode, under the same circuit connection. Electrospinning PU nanofibers are employed to integrate electrodes, maki…
Molecular dynamics (MD) can simulate the production of radiation-induced point defects in materials. However, the initial conditions of one “hypothetical” primary knock-on atom (PKA) which starts the MD simulation usually are simplified. In the present work, we aim to obtain the optimized initial conditions of PKA by…
Exploration and exploitation of radioactive ores (ilmenite, zircon and monazite) are considered as the main source of exposure to ionizing radiation of the population living in the coast of Analanjorofo Region (Fnrive-Est Districts, Rural municipality Ampasimbe Manantsatrana). Radioactivity measurements have been perf…
The mandatory presence of a chlorine atom on the aromatic ring of 6-hydroxy-3-formyl angular chromones, on the respiration inhibition of mammary carcinoma mouse, is explained through a computational study of these compounds. This study analyzes the reactivity of the neutral molecules and their free radicals, in gas ph…
A bulk polymerization monomer dehydroabietic acid-(2-acryloyloxy-ethoxy)-ethyl ester (DHA-DG-AC) was synthesized from dehydroabietic acid (DHA). The chemical structure of DHA-DG-AC was characterized by 1 H NMR, 13 C NMR, MS and FT-IR. The kinetics of the bulk polymerization of DHA-DG-AC was investigated by Differentia…
The control of disassembly of supramolecular nanostructures of the self-assembled peptides by monosaccharides was investigated for the fluorescent detection of monosaccharides in aqueous solutions.

河南邙山提灌站作为黄河流域的重要水源地之一，已列入全国重要饮用水水源地名录。邙山提灌站从黄河取水、沉沙至水厂过程中，沿途生境变化剧烈。为更好地了解这种人工行为造成不同生境中浮游植物群落结构及变化特征，于2014年6月对提灌站的黄河取水口至水厂入口沿途设置的7个采样点开展了浮游植物调查，并同步开展水温、溶氧、总磷等水质因子监测。采用极点排序（POA）和冗余分析（RDA）两种多元统计方法研究了浮游植物群落结构变化及其与环境因子的关系。结果表明：从黄河取水口至水厂取水口，浮游植物群落结构、密度与生物量沿途发生了明显变化，其中浮游植物生物量和生物多样性先升高后降低。POA分析表明7个采样断点被分成3类生境，反映了沿途的生境变化过程，而RD…
A resonance detection scheme and some useful ideas for cavity-based searches of light cold dark matter particles (such as axions) are presented, as an effort to aid in the on-going endeavors in this direction as well as for future experiments, especially in possibly developing a table-top experiment. The scheme is bas…
Rh/Cu superhydrophobic coatings with textured flower-like dual micro-nano structures were fabricated on copper substrates via electrodesposition of Rh followed by annealing treatment. The scanning electron microscopy and X-ray diffraction pattern were conducted to analyse the morphology and chemical composition of the…
The mixing temperature of hot asphalt mixture could be reduced by adding WMA additive Sasobit, as well as reducing smoke emissions and energy construction during the mixing construction and paving. The reasonable mixing temperature were investigated in this paper. In addition, high temperature stability, water stabili…
Density functional theory (DFT) calculations of glycine glutaric acid were performed by using B3LYP levels with 6-311++G(d,p) basis set. The theoretical structural parameters such as bond lengths and bond angles are in a good agreement with the experimental values of the title compound. HOMO and LUMO energies were cal…
The article explains a new method of relief marking of heat-shrinkable tubing and sleeves made of polymer materials with “shape memory effect.” Method of instrument evaluation of relief marking stereometry of installation parts for aviation equipment, made of polyvinyl chloride, polyethyleneterephthalate and polystyre…
Ein neuer Ansatz bei elektrochemischen Korrosionsuntersuchungen kann durch den Einsatz von gelartigen Elektrolyten als Alternative zu wassrigen Prufelektrolyten beschritten werden. Gelartige Elektrolyte ermoglichen minimalinvasive Untersuchungen an naturlich gebildeten Zinkdeckschichten. Dadurch konnen korrosionsrelev…
На основании предложенной ранее модели электронного спектра бинарных графеноподобных соединений типа ANB8-N построена теория адсорбции, позволяющая выявить роль положения уровня адатома, величины константы взаимодействия адатом-подложка и ширины щели, присущей в свободном состоянии графеноподобному соединению с гетеро…

The porous oxide TiO2 ceramic film containing Ca and P is fabricated on the surface of pure titanium in the electrolyte of C4H6CaO4-NaH2PO4 by micro-arc oxidation (MAO) method. The microscopic structure, elemental composition and phase components of Ceramic Film are studied with scanning electron microscopy (SEM), ene…
Li-rich layered cathode materials Li [Li0.2Mn0.54Ni0.13Co0.13]O2 with spherical morphology were synthesized via a co-precipitation method by different ways of mixing the lithium salt. The cathode materials were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM). The results show that L…
