Materials World Network: Cooperative Activity in Materials Research between US Investigators and their Counterparts in Chile

芝加哥大学的一组材料研究人员将继续与智利大学和圣地亚哥大学的同行合作研究。芝加哥-智利材料合作“的核心活动是每年为芝加哥大学的六名选定的智利学生提供为期十周的实习机会，并为同等数量的芝加哥大学学生提供智利大学的实习机会。该项目还支持教职员工双向访问。研究的中心是软材料中强烈变形的后果。该项目加强了振动和碰撞下颗粒运动的现有串联研究工作。它扩大了在前一笔拨款下产生的液体支撑分子膜的屈曲方面的合作。它进一步研究了广泛的问题，包括皱折的薄片中曲率焦点之间的相互作用，皱折的薄片和磁体中突然应力松弛事件的随机性质，令人费解的动力学增长模式，类似于分子薄膜和干燥悬浮液中的拉普拉斯生长，受限胶体悬浮液和沉积悬浮液中集体运动的异常，无序磁体中磁化信息的存储和传输，分子事件与真核细胞中有组织的爬行运动之间的联系。尽管智利合作伙伴的研究非常出色，智利学生的学术准备和学习动机也很出色，但这些教职员工和学生在科学舞台上的代表性不足。这批未被认可的人才代表着一个重大机遇。芝加哥大学的研究人员从挖掘这一人才库中受益。芝加哥学生参与者将从体验智利合作伙伴的创造性科学文化中受益。在第一个助学金期间，这些实习对许多学生的职业生涯产生了重大影响。与上一个资助周期一样，在这项研究中与领导者一起解决当前研究问题的经验预计将在这些学生中引发新的表现和活动水平。与过去的资助周期一样，预计该项目还将在伙伴机构的高级研究人员之间产生新的合作。

A group of materials researchers at the University of Chicago will continue collaborative research with counterparts at the Universidad de Chile and the Universidad de Santiago. The core activity of this ?Chicago-Chile Materials Collaboration" is to provide ten-week internships for six selected Chilean students each year at the U. of Chicago, and for a like number of University of Chicago students at the Chilean universities. The project also sponsors visits by faculty in both directions. The research centers on the consequences of strong deformation in soft materials. This project enhances existing tandem research efforts in granular motion under vibration and collision. It extends collaboration on buckling of liquid-supported molecular films engendered under the previous grant. It further investigates a broad spectrum of problems, including the interaction between foci of curvature in a crumpled sheet, the stochastic nature of abrupt stress relaxation events in crumpled sheets and in magnets, puzzling kinetic growth patterns resembling Laplacian growth in molecular films and in drying suspensions, anomalies in the collective motion in confined colloidal suspensions and in sedimenting suspensions, the storage and transport of magnetization information in disordered magnets, the connection between molecular events and organized crawling motion in eucaryotic cells. Despite the manifest excellence of the Chilean partners' research and the excellent academic preparation and motivation of the Chilean students, these faculty and students are under-represented on the scientific scene. This pool of under-recognized talent represents a major opportunity. The Chicago researchers benefit by tapping this talent pool. Chicago student participants benefit by experiencing the creative scientific culture of the Chilean partners. During the first grant period, these internships made a major impact on many of the students' careers. As in the last funding cycle, the experience of working on current research problems with leaders in this research is expected to trigger a new level of performance and activity in these students. The program is also expected to spawn new collaborations between senior researchers at the partner institutions, as in the past funding cycle.
