Conference: Nano-alloys & compounds @ IMRC 2023

非技术总结合金-由两种或多种其他金属制成的金属-对当今和未来技术的预期影响-以及它们对社会的影响-与文明史上的金属相当！此外，由于与块体合金相比，纳米合金的物理和化学性质在纳米级上观察到差异，因此对纳米合金的兴趣已经增长。事实上，在纳米尺度上有三个额外的自由度，即，尺寸、形态和偏析/有序，所有这些都在纳米结构材料的非凡性能中发挥着重要作用。纳米合金和化合物研讨会的智力价值是促进和鼓励新的合作和互动，特别是在纳米合金的新主题，如高熵合金，机器学习算法。该研讨会提供了一个关于纳米合金和化合物研究最新发展的国际论坛，作为在该领域工作的国际科学界的聚集点，同时也是促进实验和计算方法之间进一步协同作用的催化剂。参加纳米合金和化合物研讨会的学生也将有机会参加许多其他研讨会;作为主办纳米合金和化合物研讨会的国际材料研究大会，也主办其他研讨会，并在多个平行会议中运行。这种设置将对学生的心态产生有益的影响，因为它将扩大他们的视野和研究兴趣。他们参加这次活动将帮助他们完善他们的演讲技巧，网络和启动新的合作;并帮助他们找到潜在的新顾问和导师。此外，学生将有机会参加辅导课程，以了解更多关于材料科学的特定主题。技术总结为了充分利用纳米合金的结构和性能，理论推导其平衡时各相的稳定极限是非常必要的。不幸的是，这样的知识仍然缺乏，因为量热实验是非常具有挑战性的，在纳米尺度上进行，由于所涉及的小质量。因此，原位显微镜和理论预测是困难和耗时的量热实验的一个聪明和必要的补充。为了克服理解纳米合金行为的这一障碍，在2023年国际材料研究大会期间组织了一个为期两天的研讨会。它将汇集理论家和实验学家讨论新的想法，推动纳米合金领域的发展。其目标是有助于填补块体材料之间知识的差距，其中性质是由经典热力学计算的;通过支持这次研讨会，美国国家科学基金会正在促进美国学生，美国科学家和来自北美，中美洲和南美洲的国际专家之间的互动，亚洲和欧洲;所有有兴趣了解纳米合金特性的人。这次研讨会可以被认为是美国（北，中南）国会对应致力于纳米合金，补充每年在欧洲举行的。与会者提交给本次研讨会的所有贡献将被考虑出版在MRS Advances，经过严格的同行评审。该奖项反映了NSF的法定使命，并已被认为是值得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的支持。

NON-TECHNICAL SUMMARYThe expected impact of alloys – a metal made from two or more other metals – on technologies of both today and tomorrow – and their impact on society – is comparable to that of metals in the history of civilization! Moreover, interest in nanometric alloys has grown due to observed differences at the nanoscale of their physical and chemical properties compared to bulk alloys. Indeed, there are three additional degrees of freedom at the nanoscale, i.e., size, morphology and segregation/ordering, all playing a major role in the extraordinary properties of nanostructured materials. The intellectual merit of the Nano-Alloys and Compound Symposium is to promote and encourage new collaborations and interactions, especially in the new topics of nano-alloys such as high entropy alloys, machine learning algorithms. The symposium provides an international forum on the latest developments in nano-alloys and compounds research, acting as a gathering point for the international scientific community working in the field, while being a catalyst to promote further synergy between experimental and computational approaches. Students participating to the Nano-Alloys and Compounds Symposium will also have access to many other symposiums; as the International Materials Research Congress hosting the Nano-alloys and compounds symposium, also host other symposiums, and is run in multi-parallel sessions. This setup-up will have a beneficial impact on students’ mindset as it will broaden their vision and research interests. Their participation to this event will help them to perfect their presentation skills, network and initiate new collaborations; and help them finding potential new advisors and mentors. Also, students will have the opportunity to attend tutorials sessions to learn more about a specific topic in materials science.TECHNICAL SUMMARYTo fully exploit the structure and performance of nano-alloys, an theoretical deduction of their the limits of stability of the various phases at equilibrium is critically needed. Unfortunately, such knowledge is still lacking because calorimetry experiments are extremely challenging to perform at the nanoscale due to the small masses involved. Therefore, in-situ microscopy and theoretical predictions are then a smart and necessary complement to difficult and time-consuming calorimetric experiments. To combat this hurdle in understanding the behavior of nano-alloys, a -two days event- symposium is being organized during the International Materials Research Congress 2023. It will bring together theoreticians and experimentalists to discuss new ideas to move the field of nano-alloys forward. The goal is contributing to fill the gap in knowledge between bulk materials, where the properties are calculated by classical thermodynamics; and clusters, where the properties are obtained by theoretical calculations, to advance the fundamental understanding of nano-alloys.By supporting this symposium, the National Science Foundation is promoting interactions between US students, US scientists and international experts from North, Central and South America, Asia, and Europe; all who are interested in understanding the properties of nano-alloys. This symposium can be considered as the American (North, Central & South) congress counterpart dedicated to Nano-Alloys, complementary to ones held annually in Europe. All contributions submitted by the participants to this symposium will be considered for publication in MRS Advances, after rigorous peer-review.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.
