The 2nd International Conference on Heterostructured Materials (iHSM Il) will be held on December 3-6, 2024, in Chongqing, China. Heterostructured materials (HSMs) are composed of heterogeneous zones that have large differences (>100%) in mechanical or physical properties. The interactive coupling among these heterogeneous zones can produce a synergistic effect beyond the rule of mixtures and properties inaccessible by homogeneous materials. Structural HSMs include, but are not limited to, heterostructured lamella materials, gradient materials, layered materials dual-phase materials, harmonic (core-shell) materials, heterostructured composites, etc. One of the major advantages of HSMs is that they can be produced by current industrial facilities at large scale and low cost, eliminating the barrier for their practical applications. HSMs represent an emerging class of materials that are expected to become a major field of scientific exploration for the materials, mechanics, physics and computer simulation communities in the coming years. As an emerging materials field, many fundamental issues need to be probed. This is the second international conference on the fundamental science and technology of Heterostructured Materials. The first conference of this conference series, iHSM l, was held from 12th to 15th July 2022, in a hybrid mode by online broadcasting and onsite at the CityU's Hong Kong lnstitute for Advanced Study, Hong Kong. The series will continue to be held every two years, and the place of future conferences will be determined by a committee, which will evaluate proposals from different countries and regions.
