Architected materials are lightweight with high specific strength and excellent energy absorption, holding great promise for a range of applications, including automobiles, aerospace, and space. However, the absolute strength of such materials is low due to the removal of base material. To enhance the strength, stretch-dominated architectures are used, but they suffer post-yield collapses, severely limiting their energy absorption and post-yield stability, which are critical for structural applications.

The use of sound has a long history in medicine. Dating back to 350 BC, the ancient Greek physician Hippocrates, regarded as “the father of medicine,” devised a diagnostic method for detecting fluid in the lungs by shaking patients by their shoulders and listening to the resulting sounds emanating from their chest. As acoustic technology has advanced, so too has our ability to “listen” to the body and better understand underlying pathologies.

Peng Chen is currently a tenure-track assistant professor in the School of Computational Science and Engineering at Georgia Tech. In this talk, he will present a novel machine learning framework for solving optimization problems governed by large-scale partial differential equations (PDEs) with high-dimensional random parameters.

Inspiration from nature has produced some fascinating, novel, and life changing solutions for the human world. Most of these bio-inspired designs however have been product based, but taking a systems perspective when we look to nature taps inspirations that can improve the critical networks we depend on. This talk focuses on biological ecosystems in particular, complex networks of interacting species that are able to support individual needs while maintaining system-level functions during both times of abundance and unexpected disturbances.

Ocean alkalinity enhancement (OAE) is a specific ocean CDR approach that can locally reverse ocean acidification and draw additional CO2 from the air into oceanic bicarbonate where it is stored for over10,000 years, mimicking the Earth’s natural mechanism for regulating the atmospheric CO2 concentration. In this talk, I will review the latest results from my group on electrochemical ocean alkalinity enhancement and describe the efforts to commercialize this technology at Ebb Carbon, Inc.

To create metallic scaffolds or microlattices with sub-millimeter strut architectures, we develop a new method, Extrusion 3D-Printing, consisting of two simple steps. First, metal oxide particle suspensions (inks) are extruded, in air and at ambient temperature, into linear struts creating self-supporting lattices. Second, the oxides are hydrogen-reduced to metal and sintered into dense metallic microlattices.
