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.

非技术摘要合金（一种由两种或多种其他金属制成的金属）对当今和未来技术及其对社会的影响的预期影响可与文明史上的金属相媲美！此外，由于观察到纳米合金与块体合金在纳米尺度上的物理和化学性能存在差异，人们对纳米合金的兴趣也越来越大。事实上，纳米尺度上还存在三个额外的自由度，即尺寸、形态和偏析/排序，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、机器学习算法方面。该研讨会为纳米合金和化合物研究的最新发展提供了一个国际论坛，作为该领域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的催化剂。参加纳米合金和化合物研讨会的学生还将有机会参加许多其他研讨会；正如国际材料研究大会主办纳米合金和化合物研讨会一样，还主办其他研讨会，并且是多场平行会议举行。这种设置将对学生的思维方式产生有益的影响，因为它将拓宽他们的视野和研究兴趣。他们参加本次活动将帮助他们完善演讲技巧、建立人际网络并启动新的合作；并帮助他们寻找潜在的新顾问和导师。此外，学生还将有机会参加教程课程，以了解有关材料科学特定主题的更多信息。技术摘要为了充分利用纳米合金的结构和性能，迫切需要对其平衡时各相的稳定性极限进行理论推导。不幸的是，这样的知识仍然缺乏，因为由于涉及的质量较小，在纳米尺度上进行量热实验极具挑战性。因此，原位显微镜和理论预测是对困难且耗时的量热实验的明智且必要的补充。为了克服理解纳米合金行为的这一障碍，2023 年国际材料研究大会期间将组织一次为期两天的研讨会。它将汇集理论家和实验家，讨论推动纳米合金领域向前发展的新想法。目标是有助于填补散装材料之间的知识空白，散装材料的特性是通过经典热力学计算的；通过理论计算获得性能的团簇，以增进对纳米合金的基本理解。通过支持本次研讨会，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洲、中美洲、南美洲、亚洲和欧洲的国际专家之间的互动；所有有兴趣了解纳米合金特性的人。该研讨会可以被视为美国（北部、中部和南部）专门讨论纳米合金的会议，是对每年在欧洲举行的研讨会的补充。经过严格的同行评审后，与会者向本次研讨会提交的所有贡献都将被考虑在 MRS Advances 上发表。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
