Polyetherimide-Graphene (PEI/G) composites were prepared using in situ polymerization approach and thermally cured under vacuum on Stainless Steel 304 (SS304) substrates in order to be evaluated as corrosion protection coatings. Several steps curing were performed to ensure complete imidization of PEI/G composites. Di…
We have studied mechanochemical, microwave, and ultrasonic treatments of niobium pentoxide of different origin and specific surface area ( 0.1-474 m 2 / g). The aims of work were: examination of crystal, porous, and electronic structure of obtained products, evaluation of their photocatalytic activity under visible li…
BACKGROUND: The ionizing wavelength in extreme ultraviolet (EUV) resist exposure leads to photoelectron scattering and uncertainty in the resulting acid image, producing line-edge roughness (LER) and poor CD uniformity of the printed features. GOALS: Try to determine how photoelectron and acid exposure blur effects af…
Molecular Materials Ferroelectric materials are normally inorganic ceramics, such as barium titanate, but for flexible devices, molecular ferroelectrics that could readily form thin films are of interest. Xu et al. report that substitution of organic cations for potassium in an iron cyanide
The crystal structure of the Ta1207 protein from Thermoplasma acidophilum is reported. Ta1207 was identified in a screen for high-molecular-weight protein complexes in T. acidophilum. In solution, Ta1207 forms homopentamers of 188 kDa. The crystal structure of recombinant Ta1207 solved by Se-MAD at 2.4 Å resolution re…
We studied the interaction in mixture of low-dispersed crystalline zinc and tin oxides as well as in their coprecipitated X-ray amorphous composition under hydrothermal and thermal treatment. The aims of work were the study of phase composition and porous structure of obtained products as well as evaluation of their p…
Currently, fumed silica and alumina are generally known as adsorbents and supports for adsorbents and catalysts. At the same time, they, as nano-sized reagents, can be used to create modern materials containing silicates and aluminates of metals, in particular, rare-earth metals for the needs of optics, electronics an…
采用活性阴离子聚合方法，以仲丁基锂为引发剂，以苯乙烯、六甲基环三硅氧烷（D3）和2，4，6-三乙烯基-2，4，6-三甲基环三硅氧烷（V3）为反应单体，分步聚合制备了聚苯乙烯-b-聚（二甲基硅氧烷-stat-乙烯基甲基硅氧烷）[PS-b-P（DMS-stat-VMS）]嵌段聚合物.采用傅里叶变换红外光谱、氢核磁共振谱及凝胶渗透色谱对共聚物的化学结构、分子量及分子量分布进行了表征，并通过扫描电子显微镜、原子力显微镜及接触角等测试方法研究了共聚物各链段组分对共聚物形貌及表面亲疏水/油性的影响.结果表明，所制备的共聚物分子量分布较窄，由于各组分性能的差异而呈现出微相分离结构，同时该共聚物保留了PS-b-PDMS原有的表面性质，为设计结构多…

Investigations have continued for production of high performance agrobased composites using environmentally acceptable approaches. The possibility of preparing high performance agro-based composites using non toxic rice bran-modified urea formaldehyde (RB-based UF) adhesive systems is evaluated in comparison with that…
In order to review if present detection limits of radionuclides in liquid effluent from nuclear power plants are effective enough to warrant compliance with regulatory discharge limits, a risk-based approach is developed to derive a new detection limit for each radionuclide based on radiological criteria. Equations an…
In this study, the influence of stator/rotor‐pole combinations on electromagnetic performance in partitioned stator doubly salient permanent magnet (PS‐DSPM) machines is investigated, in terms of open‐circuit flux‐linkage, back‐electromotive force (EMF), cogging torque and on‐load torque characteristics. Analytical de…
The crystal structure of Pr 3 MgNi 14 D 18 was determined by neutron diffraction. The determined structure of Pr 3 MgNi 14 D 18 consisted of 89.0% Gd 2 Co 7 -type structure and 11.0% PuNi 3 -type structure.

A rapid, simple, and novel method for folate receptor α (FRα) determination is reported here. A probe of gold nanoparticles (Au NPs) modified with anti-FRα antibody was synthesized under the optimized conditions first. The antibody-modified Au NPs would aggregate when FRα was added to the probe for the specific intera…
Abstract Graphene nanomeshes (GNMs), new graphene nanostructures with tunable bandgaps, are potential building blocks for future electronic or photonic devices, and energy storage and conversion materials. In previous works, GNMs have been successfully prepared on Cu foils by the H 2 etching effect. In this paper, we…
