Current-perpendicular-to-plane structural Fe3Si/FeSi2/Fe3Si trilayered junctions were prepared on Si(111) by facing targets direct-current sputtering combined with a mask method. The shape of magnetization curves evidently exhibited that an antiparallel alignment is realized owing to a difference in the coercive force…
Tensile fracture behaviour of CFRP laminate under varied strain rate is examined in this paper. In order to evaluate the fracture behaviour and surface strain distribution change, high-speed imaging technique and DIC (Digital Image Correlation) is applied in combination. CFRP specimen having stacking sequence of [+45°…
Reduction of undesirable particles emission into the air is one of the main tasks for the environment protection. A particular problem is the emission of solid particles from the flue gases that are the product of combustion in the thermal power plant. There are several ways to reduce the emission of those undesired p…
In this work, the permanent effect of a cryogenic spill on the fracture properties of carbon steel was investigated. The experimental work consisted of two main parts. The first part was the examination of a plate of material cut from a NV E36 carbon steel platform deck, which had been exposed to a liquid nitrogen spi…
It has been established that the investigated samples of paints contain different types of organic structures. Value substances in coating materials identified by IR spectroscopy.
采用溶胶凝胶法制备了Mn-Ce/TiO2催化剂,以NH3为还原剂,通过程序升温反应考察其选择性催化还原NO的催化性能.同时,着重探讨了焙烧温度、焙烧时间、活性物质负载量及Mn、Ce负载比例对催化剂结构和性能的影响,并用BET、XRD等对催化剂进行了表征.结果表明,活性组分负载量由0增至20%时,NO转化率随着负载量的增加而提高,当(Mn+Ce)质量分数为20%,催化剂活性最高,此后随着活性组分负载量的增加,NO转化率明显下降;Mn与Ce的负载比例为0.85∶0.15时,催化剂比表面积最大,为112.31m2·g-1;焙烧温度500℃时催化剂晶相均为TiO2锐钛矿型结构,焙烧温度升高至600℃,催化剂晶相为TiO2锐钛矿型和金红石型…
This thesis provides three different design solutions for hydrogen permeation cells based on Devanathan and Stachurski method for hydrogen charging. \n\nThe first part of the thesis is built as a background analysis for the development processes. The focus lies on how the experiment functions and its critical parts, a…
Optical glassceramics are an important class of functional materials mainly employed in photonic and optoelectronic applications, as well as for advanced fiber optics. Here we present recent results on phase separation processes and optical properties of alkali germanosilicate glasses containing gallium oxide nanopart…
ポリマー改質アスファルトバインダは塑性変形抵抗性や摩耗抵抗性、はく離抵抗性等に優れており，重交通路を中心に普及している．近年では，CO2排出量削減や作業環境改善策として中温化ポリマー改質アスファルトバインダの開発も進んでおり，既に複数メーカーから市販されている．一般的に，アスファルトバインダの物理性状はDSR試験から得られるパラメータによって評価されてきたが，改質アスファルトバインダの非線形粘弾性状を適切に評価できないことが指摘されている．本研究では，国内で流通している複数の中温化ポリマー改質アスファルトバインダの性状を調査し，基本性状の相違を明らかにするとともに，物理性状評価に対して繰り返しクリープ試験(MSCR試験)の有効性を…

Suspensions of solid particles are commonly encountered in natural flows. Typical examples include soil avalanches, rock-falls, debris flows and torrential process, which cause disasters and catastrophes. A laboratory activity on high concentrated granular-fluid mixtures was carried out in order to study the flow beha…
【Soil washing with ethylenediaminetetraacetic acid (EDTA) is highly effective in the remediation of soils contaminated with heavy metals. The EDTA recycling process is a requisite for reducing the operating cost. The applicability of Na 2 S addition on the precipitation of heavy metals from the spent soil washing solu…
Insulin, a relatively low molecular weight protein has been used for decades in the treatment of diabetes; it has well-defined properties and delivery requirements. Due to the current increase of diabetes in the world improved insulin delivery systems could significantly influence the treatment of diabetes and the qua…
Epsilon-poly-lysine (epsilon-pl) is an uncommon cationic, naturally-occurring homopolymer produced by the fermentation process. due to its significant antimicrobial activity and nontoxicity to humans, epsilon-pl is now industrially produced as an additive, e.g. for food and cosmetics. however, the biosynthetic route c…
以具有核-壳结构的Au@Si O2纳米颗粒为基底,用二乙基磷酰乙基三乙氧基硅烷(DPTS)和L-胱氨酸(L-Cystine)对其进行功能化修饰制备得二乙基磷酰乙基三乙氧基硅烷和L-胱氨酸功能化纳米金粒子(L-Cys-Au@Si O2-DPTS),利用羧酸根及磷酸根与铅离子形成金属螯合物后,引起纳米粒子的聚集,导致溶液由酒红色变为蓝色,这种颜色的转变可通过肉眼直接识别,从而建立起一种简单,快速且的可用于现场实时检测Pb2+的可视化比色检测的方法。通过优化p H、底物浓度和反应时间等条件后,相较于Ni2+,Co2+,Mn2+等9种金属离子,L-Cys-Au@Si O2-DPTS对Pb2+显示出了极高的选择性。在最优实验条件下,检测Pb…
