项目摘要

0340614ZhigileiIn this three-year U.S.-France cooperative research award, Leonid Zhigilei of the University of Virginia and Tatiana Itina of the University of Aix-Marseille II will conduct computational investigation of the mechanisms of nanoparticle generation in laser ablation. Specifically, their goals are to (1) develop an advanced multiscale model of processes leading to nanoparticle formation in laser ablation of organic materials and metals and (2) perform comprehensive computational investigations of the parameters that control the evolution of the velocity, size, and spatial distributions of the ejected particles in the ablation plume. Understanding the mechanisms of nanoparticle generation in laser ablation is important for optimizing experimental conditions and for nano material fabrication or deposition of metal particles for catalysis. The project takes advantage of French experimental expertise in lasers and computational research.The project integrates research and education in computational materials science and includes training of graduate students in international multidisciplinary research. The investigators plan to integrate their research results into a graduate course on modeling in materials science. The National Science Foundation (NSF) and the Centre National de la Recherche Scientifique (CNRS) jointly support this project. NSF will cover the costs of visits to France by the U.S. investigator and graduate students. The CNRS will provide support to the French investigator for visits to the United States.

在这项为期三年的美法合作研究奖中，弗吉尼亚大学的Leonid Zigilei和艾克斯-马赛第二大学的Tatiana Itina将对激光烧蚀中纳米粒子的产生机制进行计算研究。具体地说，他们的目标是(1)建立激光烧蚀有机材料和金属中纳米颗粒形成过程的先进多尺度模型，以及(2)对控制烧蚀羽流中抛射粒子的速度、尺寸和空间分布演变的参数进行全面的计算研究。了解激光烧蚀过程中纳米粒子的形成机理，对于优化实验条件，制备纳米材料或制备催化用金属粒子具有重要意义。该项目利用法国在激光和计算研究方面的实验专业知识。该项目整合了计算材料科学的研究和教育，并包括培养国际多学科研究的研究生。研究人员计划将他们的研究成果整合到一门关于材料科学建模的研究生课程中。国家科学基金会(NSF)和国家科学研究中心(CNRS)共同支持这一项目。NSF将支付美国调查员和研究生访问法国的费用。国家研究中心将为法国调查员访问美国提供支持。
