Dynamic Monte Carlo study on the probability distribution functions of tail-like polymer chain

INTRODUCTION Polymer chains with one end attached to a sur- face by means of physical or chemical interaction have become one of the important polymer science subject, which are useful for many applications, such as polymer compatibilizers, copolymer microphases, colloid stabilization, polymeric surfactants (Milner, 1991). Grafting polymers can improve the power efficiency of electrorheological fluids, enhance pho- toluminescence of nano materials, and increase dis- persion stability. On …

Learning to make change happen in Chinese schools: adapting a problem-based computer simulation for developing school leaders

School leader training has become a critical strategy in educational reform. However, in China, there still exists a big gap in terms of how to transfer leadership knowledge into practice. Thus, tools that can integrate formal knowledge into practice are called for urgently in school leader training. This paper presents the results of a research and development (R&;D) approach to adapt an existing online computer simulation, Making Change Happen?, for use in Mainland China. The paper describes the process used to inform and assess our cultural adaptation of the simulation, as well as the response of Chinese principals to learning through this innovative method. Results affirmed the necessity for cultural adaptation of ‘Western’ curricula and tools for use in the Chinese context. The positive response of the Chinese school principals to learning via an online computer simulation suggested future potential for employing technology-facilitated, active learning modes in China. Implications are outlined for theory, research, and practice.     

交流电热效应操控纳米粒子在芯片实验室中的应用

为寻求一种驱动电导率(大于0.02S/m)溶液的新方法,探讨了利用交流电热效应驱动高电导率微流体.根据交流电热效应理论,建立了交流电热粒子诱捕物理模型,利用仿真软件FEMLAB对其进行仿真分析研究,并通过实验对其进行验证.实验结果表明:利用特定的微电极芯片结构和交流电热效应,能驱动流体电导率高达1.53S/m的微流体,实现了在低电势下的粒子诱捕.利用交流电热效应驱动微流体,不仅能够实现对微粒的诱捕,而且输入信号电势低,受微流体影响小,容易与芯片集成.研究结果为设计交流电热效应芯片实验室提供了参考依据.
