Nel vasto scenario dei materiali fortemente correlati gli ossidi dei metalli di transizione hanno attratto enorme interesse a causa delle loro interessanti proprietà fisiche, come ad esempio, la superconduttività nei cuprati e la magnetoresistenza gigante nelle manganiti. In particolare, il mio interesse è stato rivol…
Carbon nanotubes (CNT) are based on one or more sheets of graphite rolled up into a tube. Adding carbon nanotubes, the electrical resistivity of cementitious composites changes by varying the stress conditions. Variation in the electric resistivity can be ascribed to the increase in the number of contact points of CNT…
以硫化脂肪类添加剂二烃基五硫化物(RC2540)为芯材, 三聚氰胺-甲醛树脂(MF树脂)为壁材, 采用原位聚合法合成了RC2540-MF树脂微胶囊。使用红外光谱、 SEM及热重分析(TG)等对其性能进行表征。用四球摩擦副考察了RC2540-MF树脂微胶囊作为聚乙二醇基础液添加剂时的摩擦磨损性能。结果表明: 添加质量分 数3% RC2540-MF树脂微胶囊的聚乙二醇基础液在314 N下摩擦系数可低至0.04, 磨斑直径在314 N(RC2540-MF质量分数5%)下为0.54 mm, 实验载荷则可以提高至1000 N以上。这是由于摩擦力导致RC2540-MF 树脂微胶囊破损, 活性硫化物在摩擦表面的物理、 化学吸附作用和生成的摩擦化…
Precipitation processes are widely used in chemical industry for the production of particulate solids. In these processes, the chemical and physical nature of synthesized particles is of key importance. The traditional stirred tank batch reactors are affected by non-uniform mixing of reactants, often resulting in broa…
Several aspects pertaining to the measurements of trace radionuclides (such as plutonium) in soil samples by L x-ray detection have been considered. A 3 x 3 multiplexed array of edge-mounted Si detectors with a total detection area of 50 cm/sup 2/ and FWHM resolution of 300 eV at 17 keV has been conceived. The fractio…
Abstract : This report documents efforts performed, between May 2011 and November 2012, under a Broad Agency Announcement contract between the American Sheep Industry Association (ASI) and the Natick Soldier Research, Development and Engineering Center (NSRDEC). The objective was to develop flame resistant combat unif…
This book provides a good update and review of the literature on the lung cancer risks induced by radon exposure. It demonstrates that there has been extensive literature published on these effects...
