U.S.-Argentina Workshop on Structure and Topograpy of Surfaces; LaPlata, Argentina, November 1997

9722042斯蒂尔这一美洲计划奖将资助美国和阿根廷联合举办的表面科学方面研讨会，该研讨会将于1997年11月在阿根廷拉普拉塔举行。组织者是宾夕法尼亚州立大学的威廉·斯蒂尔博士和拉普拉塔Fisicoquimicas Teoricas y Applicadas研究所(INIFTA)的爱德华多·博塔尼博士。研讨会将汇集美国和阿根廷的科学家，介绍和讨论表面科学的最新研究，并探索在未来工作中合作的可能性。现代表面科学涵盖了广泛的主题。本研讨会将讨论的子领域包括：表面非均质性及其对吸附在这种表面上的分子的扩散、热力学和化学反应的影响；表征表面非均质性的方法，如分维或给定能量的吸附位置之间的相关性的距离依赖关系；以及在表征良好的表面上的化学吸附和化学反应。这些主题处于当前涉及曲面的研究的前沿。表面科学是一门在过去20年里经历了爆炸性增长的学科，这是因为引入了强大的新技术来可视化和表征在化学活性固体表面形成的物种。它对催化、提纯过程、腐蚀、磨损和润滑以及制造越来越小的计算机芯片都是非常重要的。***

9722042 Steele This Americas Program award will fund a joint USA-Argentina workshop on aspects of surface science, to be held in La Plata, Argentina, November, 1997. Organizers are Dr. William Steele, Pennsylvania State University, and Dr. Eduardo Bottani, Instituto de Investigaciones Fisicoquimicas Teoricas y Applicadas (INIFTA), La Plata. The workshop will bring together scientists from US and Argentina to present and discuss the most recent studies on surface science, and explore the possibilities of collaboration in future work. Modern surface science covers a wide variety of topics. Subfields to be discussed in this workshop include surface heterogeneity and its influence on the diffusion, thermodynamics and chemical reactivity of molecules adsorbed on such surfaces; methods of characterizing surface heterogeneity, such as fractal dimension or the distance dependence of the correlation between adsorption sites of a given energy; and chemisorption and chemical reactivity on well characterized surfaces. These topics are at the forefront of current research involving surfaces. Surface science is a subject that has seen explosive growth over the past two decades due to the introduction of powerful new techniques for visualizing and characterizing the species that form on the surfaces of chemically active solids. It is of enormous importance to catalysis, to purification procesqes, to corrosion, wear and lubrication, and to the fabrication of ever-smaller computer chips. ***
