报 告 人：张现仁教授

时 间：2009年11月11日下午2:00～4:00

地 点：会议中心中心会议室

张现仁，2001年获北京化工大学博士学位。2001．6-2003.3在北京化工大学从事博士后研究，2003.3-2005.3在法国Ecole Normale Superieure de Lyon化学系从事博士后研究。2005年回到北京化工大学任教.在Langmuir, Physical Review等期刊发表论文40 余篇。并先后获得北京市科技进步（基础类）一等奖和教育部高等学校科学技术（自然科学）二等奖。

目前主要的研究方向包括：

（1） 限制空间中流体相行为研究

（2） 表面双亲分子的自聚行为

（3） 生物膜及跨膜输运的理论研究

本次报告内容简介：

表面双亲分子通常包含亲水和疏水两部分，这种特殊的分子结构决定了表面双亲分子在溶剂中的自组织行为。报告将首先对表面双亲分子的性质和应用做一个简单介绍。然后按我们四年来关于表面双亲分子的自聚研究为主线阐述我们对其自聚行为的理解。这部分将内容包括以下三个方面：（1）表面双亲分子的吸附动力学，自聚形态以及相行为，(2) 表面双亲分子作为模板剂诱导的纳米材料的有序形态，以及（3）具有表面双亲性的磷脂分子组成的生物膜的结构性能关系。
