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

小行星9722042 这项美洲方案奖将资助1997年11月在阿根廷拉普拉塔举行的美国-阿根廷表面科学联合讲习班。 组织者是宾夕法尼亚州立大学的William Steele博士和拉普拉塔的财政和应用研究所的Eduardo Bottani博士。 研讨会将汇集来自美国和阿根廷的科学家，介绍和讨论表面科学的最新研究，并探讨在未来工作中合作的可能性。 现代表面科学涵盖了各种各样的主题。 本次研讨会将讨论的子领域包括表面异质性及其对吸附在此类表面上的分子的扩散、热力学和化学反应性的影响;表征表面异质性的方法，如分形维数或给定能量的吸附位点之间的相关性的距离依赖性;以及表征良好的表面上的化学吸附和化学反应性。 这些主题是当前涉及曲面的研究的前沿。 表面科学是一个在过去二十年中由于引入了强大的新技术来可视化和表征化学活性固体表面上形成的物种而出现爆炸性增长的主题。 它对催化、净化过程、腐蚀、磨损和润滑以及越来越小的计算机芯片的制造都具有巨大的重要性。 ***

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. ***
