The desire to monitor important neurotransmitters in the in vivo environment, in real-time and in conscious subjects has been the driving force behind the continued development over the last 40 years of a range of biosensor devices. This is a none too difficult task considering the milieu of substances that are presen…
La reduccion en las dimensiones caracteristicas de los dispositivos semiconductores, asi como la utilizacion de elementos nanoestructurados para su construccion, estan permitiendo no solo una mejora en la potencia de calculo y capacidad de almacenamiento de los microprocesadores, sino la investigacion de nuevos materi…
The research aims the deposition of low thickness ceramic films on the surface of cast iron forms that are used for recycled Pb moulding. The films will establish a thermal insulating coating to delate the metal solidification for a short time in order to complete an unforced mechanical scorification. Moreover the bar…
Transmembrane integrin receptors modulate a wide variety of cellular functions, like survival, proliferation, adhesion and extracellular matrix (ECM) assembly. The major ligand of a5b1-integrin is fibronectin (FN), a key component of the ECM. This glycoprotein can be found as fibrillar network in different tissues (ce…
本文采用真空电子束蒸发镀膜工艺制备Nd:YAG薄膜，结合XRD、SEM等手段分析研究不同衬底材料、镀膜材料以及退火温度对薄膜材料结构的影响，并分析测试了Nd:YAG薄膜的光致发光特性。镀膜材料为Nd:YAG粉体块，Si片上沉积的Nd:YAG薄膜材料，经1100˚C退火后，具有单一YAG晶相结构，薄膜结晶晶粒均匀细小，并在室温下测试获得1064 nm主荧光峰的宽带荧光光谱。 Nd:YAG thin films have been prepared by electron beam evaporation deposition in the study. The influences of different substrates,…
In biological systems, various components at multiple levels from small molecules to organs work coordinately to perform their advanced and non-linear functions. Such biological systems are attractive and useful for developing new materials. In our strategy for development of a new material, we consider materials as o…
The cobalt cyclotetraphosphate was synthesized by two step reaction . The first reaction between matal carbonate and phosphoric acid forming metal di-hydrogen phosphate precursor .2nd the precursor fired and sintered at elevated different temperatures to optimize best conditions to obtain Co2P4O12 crystal form with hi…
Diese Arbeit widmet sich den strukturellen Eigenschaften und der thermischen Stabilität monodisperser metallischer Nanopartikel im Größenbereich von 0,5–1,8nm. Sie zeigen ein nicht-skalierendes Verhalten und deswegen sind solche Informationen für zukünftige nanotechnologische Anwendungen von Interesse. Die Technik der…
Water disinfection is the removal, deactivation or killing of the pathogenic bacteria and micro-organisms by chemical or physical disinfection. Many industries are very positive about the different opportunities used with nanotechnology. Titanium Dioxide (TiO2) was recognized as an effective method of disinfection mec…
The electrodes of secondary batteries degrade during consecutive intercalation cycles, thus reducing the units’ capacity. The amorphous nature of an electrode could theoretically lower the degree of such degradation. Since a vanadium tellurite system exhibit high electronic conductivity and the ability to intercalate…
Thermal expansion coefficient is a basic physical property which can be of great importance in mechanical and structural design applications of materials. Despite many published literature of expansion coefficients for common metals and alloys, there is a need to measure this property for a specific material over a sp…
Thermoelectric generators (TEG) can convert waste heat that abounds in modern societies into electricity in an environmentally friendly and reliable manner. The development works mostly focused on thermoelectric materials required a significant amount of heat and mass transfer optimization and engineering parametric a…

The approach was to first investigate the physical prop…
Two different approaches are used for predicting of elastic properties of polymer composites reinforced by knitted fabric: numerical (FEM) modeling and inverse method based on vibration analysis.
The results present on the influence plastic zone on process graphitization and on the places of pick outs of graphit inclusions in the steel of mark 09G2C.
碳化硼是一种重要的特种陶瓷材料，具有低密度(2.52 g/cm3)、高熔点(2450˚C)等优异的物理化学性能。但由于其烧结温度过高、难以致密化及韧性低等缺点，限制了它的应用。针对该问题研究通过非均相沉淀法制备了兼具B4C结构陶瓷超轻高强与Cu/Ni合金优良抗生物污损两大优势性能的Cu/Ni增韧B4C基陶瓷–金属复合材料。探究了B4C表面预处理、溶液中金属离子浓度、Cu/Ni在复合粉体中比例因素对复合粉体中Cu/Ni对B4C的包覆的影响。此外，简单地分析了烧结温度对Cu/Ni-B4C金属陶瓷复合材料的致密化程度的影响。 Boron carbide (B4C) is an important ceramic material wit…
The use of natural fibers as reinforcement in polymer matrix composites is gaining popularity in the development of renewable products. Although glass and other synthetic fiber-reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of prod…
