Inverse Design of Mechanical Metamaterials with Target Nonlinear Response via a Neural Accelerated Evolution Strategy
Katia Bertoldi (Mechanics) and Chris Rycroft (Applied Math)
A team at the Harvard MRSEC led by Bertoldi and Rycroft has developed a framework to design mechanical metamaterials with target nonlinear response. Neural networks were used to accurately learn the relationship between the geometry and nonlinear mechanical response of these metamaterials.

Monitoring the Solution Persistence of Porous Coordination Cages with Diffusion NMR Spectroscopy and Cryogenic Transmission Electron Microscopy
G. Taggart, A. Guliyeva, K. Kim, G. Yap, D. Pochan, T. Epps, E. Bloch (University of Delaware), University of Delaware MRSEC DMR-2011824
Here, diffusion of NMR spectroscopy, transmission electron microscopy, and cryogenic transmission electron spectroscopy were used to characterize porous cages in solution. A combination of the methods can be used to discriminate between assembled cages as opposed to decomposed or isomerized materials while dissolved in polar organic solvents, regardless of the metal cations used in their assembly.
