Structural woven composites made with high strength fibres are now widely used in automotive and aeronautic engineering due to their high strength/weight ratio as compared with metals. During the forming process, though the extension of the woven composite fabrics is usually small, the shear deformation (i.e., the ang…
Eu(TTA)3DPBT was found most likely to lead a special singlet photosensitization pathway by means of time-resolved luminescence spectroscopic studies.For further understanding of its intra-molecular energy transfer mechanism,another lanthanide complex Eu(TTA)3BDDT was synthesized,using a related ligand BDDT,changing th…
The data of influence of layers thickness in the nanostructured metallic composites Cu-Nb and Nb-(Nb-Ti) on mechanical properties and critical superconducting current density in external magnetic field are presented.
Torvbränslen används ofta i kombination med trädbränslen i värme- och kraftvärmeverk. Den kombinationen har visat sig ge förbränningstekniska fördelar kanske främst minskad risk för askrelaterade driftsproblem. Erfarenheter saknas dock vad gäller eventuella positiva sameldningseffekter/erfoderliga inblandningsgrader a…

This paper presents preliminary results from surface characterisation of gold electrodes using SIMS, SEM and synchrotron soft x-rays from a study undertaken to investigate the surface of solid gold electrodes after subjecting electrodes to various electrochemical processes. The aim was to improve the sensitivity and r…
Due to the large volume fraction of grain boundaries (GB’s) and a random orientation of the crystallographic axes, nanocrystalline inert-gas condensed materials are common model systems for investigating the impact of internal interfaces and reduced structural length scales on the macroscopic properties of real solids…
采用种子乳液聚合法合成了马来酸酐官能化的核-壳结构聚丙烯酸酯类冲击改性剂（AIM—g—MAH，简写为mAIM），并用熔融挤出法，制备mAIM／PA6合金。采用傅里叶红外光谱、动态激光粒度分析仪、扫描电镜表征了mAIM的结构特征；考察了mAIM的粒径、核壳比、马来酸酐含量、mAIM与PA6的共混比例对mAIM／PA6合金的力学性能的影响。结果表明：当mAIM粒径为350nm左右，核壳比为85／15，马来酸酐的含量为1％，PA6与mAIM的共混比例为70／30时合金的冲击强度最好，冲击强度为290J／m，比纯PA6树脂提高了6倍左右。
Funktionelle Gruppen bestimmen als „aktive Stellen“ im Molekül die chemischen Eigenschaften, während sich das Kohlenwasserstoffgerüst reaktionsträge verhält. Organische Verbindungen werden nach dem Stammkohlenwasserstoff benannt und die funktionellen Gruppen und Seitenketten alphabetisch voran gestellt. Die höchstwert…
采用SEM、EDS、XRD和XPS等分析手段研究了HFC-125/N2混合气体对AZ91D镁合金熔体的保护效果,以及所形成的表面膜的形成过程。结果表明：HFC-125可以对镁熔体提供长期有效的阻燃保护;所得镁熔体表面膜主要由MgF2构成;随着时间的延长,表面膜内Mg含量逐渐减少,F含量逐渐增多。
第一原则的计算为电子的手结构的学习和两倍 perovskite Ca2CrSbO6 的铁磁性的性质被执行了。状态的密度，全部的精力，纺纱磁性的时刻，和费用密度在细节计算、分析。Ca2CrSbO6 有磁性的时刻每分子关于 2.99B 的一个稳定的铁磁性的地面状态和旋转，这被发现。铬在全部的磁性的时刻贡献大多数。结果显示 Ca2CrSbO6 是一半金属性的。

Chemically functionalized surfaces find applications in a large variety of research topics. In particular, self-assembled monolayers represent a powerful approach to tailor the properties of surfaces. The fast and easy preparation of such layers, next to the high order of molecular organization are regarded as a major…
El aluminio y el bronce pertenecen a los materiales no ferrosos y cumplen con la característica de ser cien por ciento reciclables, además el aluminio presenta como ventaja el requerir sólo un cinco por ciento de la energía necesaria para regresar al metal primario inicial. Para producir aluminio a partir del reciclaj…
Porous solids are a class of materials of high scientific and technological significance. Indeed, they have the ability to interact with atoms, ions or molecules not only at their surface but also throughout the bulk of the solid. This ability places these materials as a major class involved in many applications such…
2008年，荷兰品牌银彩（Sitech）开发了第7代冶金技术（G7）。这是从第6代的G6发展到第7代的G7。他们从1983年用纯银导体的G1冶金技术生产第一款音响线后不断在导线的金属材料上挖掘创新，透过纯金填补银结晶间隙的G3冶金技术，跨出音响导线导体材料的新领域，在此基础上．不断有新的技术推出．其中有将线材进行SATT（Sillech Advanced Thermal Treatment）“冰火极温处理”，
A series of previously unreported 2-alkyl-1-(2-diethylamino(morpholino)methyl-carbonylethoxy)pyrroles have been synthesized via interaction of 2-alkyl-1-(2-hydroxyethyl)pyrrolts with chloroanhyride of monochloroacetic acid, and their antimicrobial activity has been studied. It is established that electron-acceptor sub…
Tensile testing on short fiber reinforced composites is helping to identify the advantages and disadvantages of different rubber compounds
Self-sensing on micro-failure, dispersion degree and relating properties, of carbon nanotube(CNT)/epoxy composites, were investigated using wettability, electro-micromechanical technique with acoustic emission(AE). Specimens were prepared from neat epoxy as well as composites with untreated and acid-treated CNT. Degre…
