A new workshop series, called the Controversies Colloquium, is aimed at providing a venue where thought leaders and subject matter experts can gather to discuss long-standing or new "controversies" in scientific fields, where gaps in knowledge exist that prevent the full understanding of critical scientific phenomena. The first of these workshops is on the subject of the Stability of Nanostructures, and is scheduled to occur February 1-2, 2018, at the University of California-Irvine, in Irvine, CA. This award supports participation by early career scientists and researchers in the Colloquium. The non-traditional small-group presentation and discussion formats will encourage and promote free-flowing scientific dialogue and critical debates, and participation by a diverse group of attendees will provide broad perspective. The structure is intended to inspire a highly active meeting where all participants are constantly engaged. This workshop will move the field closer to achieving truly stable nanomaterials, providing a service to the materials community and broad impact to a number of industries where high strength, lightweight, damage-tolerant materials are needed, including aerospace, automotive, and energy sectors.Nanostructured materials exhibit extreme strength, wear-resistance, fatigue-life and other mechanical properties, but are often limited by the instability of their microstructures. A recent point of focus in the community has been the stabilization of nanoscale grain structures through a variety of techniques that invoke both thermodynamic and kinetic approaches. However, the field is relatively scattered and there is disagreement about the best approaches and the fundamental scientific mechanisms. This workshop aims to help guide the community to close the book on old issues in the field and identify new outstanding problems, using an informal format.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

一个新的研讨会系列，称为争议讨论会，旨在提供一个场所，思想领袖和主题专家可以聚集在一起，讨论科学领域长期存在的或新的“争议”，其中存在的知识差距阻碍了对关键科学现象的充分理解。这些研讨会的第一个主题是纳米结构的稳定性，并定于2018年2月1日至2日在加州大学欧文分校举行。该奖项支持早期职业科学家和研究人员参加学术讨论会。非传统的小组演讲和讨论形式将鼓励和促进自由流动的科学对话和批判性辩论，不同与会者群体的参与将提供广阔的视角。该结构旨在激发一个高度活跃的会议，所有与会者都不断参与其中。该研讨会将使该领域更接近于实现真正稳定的纳米材料，为材料界提供服务，并对一些需要高强度，轻质，耐损伤材料的行业产生广泛影响，包括航空航天，汽车和能源部门。纳米结构材料具有极高的强度，耐磨性，疲劳寿命和其他机械性能，但通常受到其微结构不稳定性的限制。 最近的一个焦点在社会上一直是稳定的纳米晶粒结构，通过各种技术，调用热力学和动力学的方法。 然而，该领域相对分散，对最佳方法和基本科学机制存在分歧。 该研讨会旨在帮助指导社区关闭该领域的旧问题，并使用非正式的格式确定新的突出问题。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
