Molecular imprinted polymer (MIP) for melamine has been fabricated using precipitation polymerization method using methacrylamide and 9-vinylcarbazole. The molecular imprinted polymer was characterized using Fourier transform infrared spectroscopy, thermo gravimetric analysis, photon cross correlation spectroscopy ana…
Liquid metals have excellent properties to be used as heat transport fluids due to their high thermal conductivity and their wide applicable temperature range. The latter issue can be used to go beyond limitations of existing thermal solar energy systems. Furthermore, the direct energy converter Alkali Metal Thermo El…
The article provides the context for finding out how van der Waals model is applied to describe average spectral-response characteristics of interatomic dipoles of metals with bcc and fcc crystal lattice. The formula for emission ability from crystal surface has been discovered and changes for electronic contribution…
Abstract Carpenter SCF 260 alloy is an austenitic nitrogen-strengthened stainless steel of very high manganese content. The alloy is used for downhole equipment and where pitting is present. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture…
In anoxic, carbonated and slightly acidic burial environments, the growth of siderite crystals on archaeological iron has been attributed a passivating effect on the corrosion process. By creating a simplified, though similar environment (optimized for siderite growth), the aim of this project was to observe how the g…
AMAÇ: Zirkonya seramik restorasyonların adeziv simantasyonu için seramik yüzeyini hazırlama yöntemlerinin kompozit rezin siman ile zirkonya seramik ara yüzeyindeki bağlanma direnci üzerine etkilerini incelemek ve bağlanma direnci açısından etkili olan en iyi yöntemi belirlemektir.YÖNTEMLER: Bu çalışmada, her bir grupt…
Sewing techniques are sometimes overlooked in the design process but acquiring these skills can be transformational. The ability to turn a two-dimensional design into its three-dimensional realization comes from having mastered basic sewing techniques. Sewing Techniques simplifies the often complex techniques that lie…
高速増殖原型炉「もんじゅ」に適用される新しい規制基準については，今後安全審査を行うまでに見直すこととされている。日本原子力学会新型炉部会では，今後の見直し検討に資することを期待して本検討会を設置して検討を重ね，現行規則を分析して論点を整理するとともに，論点に対する考え方をまとめた1）。この中で，ナトリウム冷却高速炉の特徴を踏まえた重大事故対策の考え方及び現行規則とその解釈の見直し案を示した。本稿では，ナトリウム冷却高速炉の安全設計上の特徴を軽水炉と比較して示すとともに，本検討会での検討結果を解説する。
采用动态硫化法制备了嵌段共聚聚丙烯（PP-b-PE）/三元乙丙橡胶（EPDM）热塑性硫化胶（ TPV），研究了其力学性能、压缩永久变形的可逆回复、Mullins效应及微观形态。结果表明，当PP-b-PE/EPDM质量比为30/70时TPV的综合性能较好；室温条件下压缩永久变形的可逆回复随TPV中橡胶相含量的升高而明显加快，且残余形变较小；提高温度可加速TPV永久变形的可逆回复，且高橡胶含量者的形变完全可逆。 PP-b-PE/EPDM TPV的单轴循环拉伸中存在明显的Mullins效应，在同一拉伸比下，内耗和阻尼因子在第1次加载-卸载循环中即达到最大值，第2次循环拉伸时明显下降，但之后下降趋势减缓，应力最大值则呈现缓慢下降的趋势。提…
Les Nations Unies ont décrété l'année 2014 année internationale de la cristallographie. A cette occasion, le Jardin des sciences de l'Université de Strasbourg a proposé un certain nombre d'actions, en direction du grand public comme des publics scolaire et universitaire. Parmi les manifestations, l'exposition Les 1001…
A detailed spectro-temporal analysis of the ultrafast transient absorption and fluorescence signals allows deciphering multiple energy and charge transfer processes in a light-harvesting molecular triad designed as photo-sensitizing unit featuring a novel BODIPY compound.
On July 10, 1991, a Maintenance Rule, Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, was published by the U.S. Nuclear Regulatory Commission (the USNRC, or simply the NRC) in the Federal Register (56FR31324) as 10CFR50.65. This Maintenance Rule was developed to provide a regulato…
In this Letter, the authors report an AC conductivity analysis on the [Fe(Htrz) 2 (trz)](BF 4 ) spin crossover complex and reveal the spin-state dependence of the electrical conductivity, permittivity and modulus in a broad frequency range. This study confirms recent findings in spin-state dependent conductivity measu…
Chitosan is the deacetylated derivative of chitin Chitosan is the only basic polysaccharide in nature. It is greatly dominant to be used as a drug carrier due to the non-toxicity Chitosan with good biocompatibility and biodegradation has widely application in many fields, such as wastewater treatment
The introduction of inorganic nanoparticles into organic materials enhances both the mechanical and chemical properties of the material. Metallic nanoparticles, like silver and gold, have been introduced into polymers for use as antimicrobial coatings or dielectric materials, respectively. The challenge in creating th…
Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden, Germany are currently testing a solid oxide fuel cell at the Dresden sewage works, running on methane extracted from municipal sewage.
A series of poly(γ-benzyl L-glutamate) (PBLG) and poly(γ-benzyl L-glutamate)-block-poly(ethylene glycol) (PBLG-block-PEG) mixture films (mole ratio is 1:1) modified by polyurethane were prepared by casting the polymer blend solution in N,N-dimethylformamide.Surface morphologies of the polymer blend films were investig…
To understand the photoreactivity of aminobenzonitrile and benzopyran, their electronic structures and the potential energy landscapes were analyzed at the CASSCF level and models were developed to perform quantum dynamics calculations.
T he term “model” is often used to refer to some person or object—a person who shows-off clothing designs, or a small-scale replica of any of a variety of things. How does a model car differ from a toy car, though? How does a clothing model differ from someone who is simply wearing the same clothes? How does a mathema…
