His 一九六零 mass-produced patent of safety ski binding is exhibited in New England Ski Museum.Home: developing new materials, the research objective has been to maximize the mean strength (or fracture energy) of material or structure and minimize the coefficient of variation. However, for engineering structures such as airframes, bridges of microelectronic devices, the objective should be to maximize the tail probability strength, which is defined as the strength corresponding to failure probability 10-6 per lifetime. Optimizing the strength and coefficient of variation does not guarantee it. The ratio of the distance of the tail point from the mean strength to the standard deviation depends on the architecture and microstructure of the material (governing the safety factor) is what should also be minimized. For the Gaussian and Weibull distributions of strength, the only ones known up to the 1980s, this ratio differs by almost 2:1. For the strength distributions of quasibrittle materials, it can be anywhere in between, depending on material architecture and structure size. These materials, characterized by a nonnegligible size of the fracture process zone, include concretes, rocks, tough ceramics, fiber composites, stiff soils, sea ice, snow slabs, rigid foams, bone, dental materials, many bio-materials and most materials on the micrometer scale. A theory to deduce the strength distribution tail from atomistic crack jumps and Kramer’s rule of transition rate theory, and determine analytically the multiscale transition to the representative volume element of material, is briefly reviewed. The strength distribution of quasibrittle particulate or fibrous materials, whose size is proportional to the number of RVEs, is obtained from the weakest-link chain with a finite number of links, and is characterized by a Gauss-Weibull grafted distribution. Close agreement with the observed strength histograms and size effect curves are demonstrated. Discussion then turns to new results on biomimetic imbricated (or scattered) lamellar systems, exemplified by nacre, whose mean strength exceeds the strength of constituents by an order of magnitude. The nacreous quasibrittle material is simplified as a fishnet pulled diagonally, which is shown to be amenable to an analytical solution of the strength probability distribution. The solution is verified by million Monte-Carlo simulations for each of fishnets of various shapes and sizes. In addition to the weakest-link model and the fiber-bundle model, the fishnet is shown to be the third strength probability model that is amenable to an analytical solution. It is found that, aside from its well-known benefit for the mean strength, the nacreous microstructure provides a significant additional strengthening at the strength probability tail. Finally it is emphasized that the most important consequence of the quasibrittleness, and also the most effective way of calibrating the tail, is the size effect on mean structural strength.

Jianyong OuyangDepartment of Materials Science and Engineering, National University of 新加坡共和国Conducting polymers were discovered in 1968s. Recent progress in conducting polymers demonstrated their important applications, such as the next-generation transparent electrode and thermoelectric materials. Optoelectronic devices require at least one electrode to be transparent. Indiun tin oxide is traditionally used as the transparent electrode of optoelectronic devices. But ITO has problems of scarce indium on earth and poor mechanical flexibility. Conducting polymers, carbon nanotubes, graphene and metal wire grids have been proposed to be the transparent electode materials. Among them, poly(3,4-ethylenedioxythiopheneState of Qatar:poly(styrenesulfonate卡塔尔(قطر is promising to be the next-generation transparent electrode material due to its solution processability, low cost and high transparency in visible range. However, the as-prepared PEDOT:PSS film obtained from PEDOT:PSS aqueous solution usually has conductivity below 1 S cm-1, remarkably lower than ITO. Here, I will present several novel methods to significantly enhance the conductivity of PEDOT:PSS. The conductivity can be enhanced to be more than 3000 S cm-1, which is higher than that of ITO on plastic and comparable to ITO on glass. Moreover, highly conductive PEDOT:PSS can have high thermoelectric properties. They can be used for heat harvesting and cooling at low temperature.报告人简要介绍：欧阳建勇 教师，毕业于清华东军事和政治高校学化学系，在中科院化学所和东瀛分子调查切磋所得到大学生和博士学位，曾经在东瀛北陆先端科学手艺大学院大学和美利坚合众国加利福尼亚州大学雅加达分校作助理教授和硕士后。二〇〇七年参加新加坡国立大学资料与科学工程学院，研商方向归纳有机电子、存款和储蓄器件及皮米质地等，在Nature Materials、Nature Nanotechnology、Nature Communications、Advanced Materials、Nano Letters等学术刊物上刊载杂文100余篇，平均每篇小说的援引>七十九次。个中多篇探讨成果被MIT Technology Reviews、world journal、azonano.com、Nanotechweb、Journal of Materials Chemistry等电视发表或评为年度亮点作品。重要钻探成果包含发明了社会风气上率先个高分子/飞米颗粒存款和储蓄器和刷新了可加工导电高分子的电导和热电品质的社会风气记录。
