Abstract
The rapid growth of the modern world demands next-generation intelligent materials and structures to be smart, self-reliable, efficient and durable. In the past decade, nanomaterials, including 1D and 2D materials, have become the most prominent candidates since they often exhibit superior electro-chemo-mechanical properties in comparison with their bulk counterparts. In addition, with the help of advanced electron imaging technologies, we can investigate their structural-to-property relationships at atomic scale and engineer them through bottom-up approaches. These advantages allow us to manufacture multi-functional composite materials for superior mechanical strength, energy storage, electro-chemical, bio-sensing, self-actuated robots, and lightweight structures.
In this talk, Chenglin Wu will present his team’s recent work in the following areas:
- Synthesis and characterization of low-dimensional functional materials including graphene, MXene and nanowires. His team utilized the AFM, nanoindentation, push-to-pull MEMS device, and laser-induced projectile impact test to conduct nanomechanics investigations to understand the fundamental structure-to-property relationship of low-dimensional functional materials and their composites.
- Advanced electro-chemical-optical sensors and intelligent systems. Wu’s team has developed advanced transfer method to fabricate nanoscale fiber-optic corrosion sensors, wireless long-range strain sensors as well as on-mask SARS-CoV-2 and influenza virus sensors utilizing the functional low-dimensional materials.
- Multi-scale and multi-physics modeling. To understand some fundamental physical problems, Wu’s team of researchers has also developed the phase-field methods to investigate multi-scale and multi-physical fracture problems.
- Machine learning material discovery and system design. To satisfy the design needs, Wu’s team has built a robotic mechanism to perform material characterization and computationally aided design approaches.
- 3D printing infrastructure. Wu’s team has developed unique printing approaches that can print soft robots and reinforced concrete structures, where the interfacial mechanisms are critical to the performance of the printed robots and structures.
