Deactivating Viruses Using Self-Assembling DNA Origami Shells
S. Fraden1, G. Grason2, R. Hayward2, M. Hagan1, W. Rogers1, C. Santangelo2,H. Dietz3 1Brandeis University, 2U. Mass. Amherst, 3Tech. Universität München
Researchers have developed programmable DNA origami building blocks that self-assemble into icosahedral shells, with programmable sizes. The shells can be functionalized with antibodies, enabling them to engulf and neutralize natural viruses.

Development of New Active Materials
1,2Z. Dogic ,1G. Duclos, 1S. Fraden and 1B. Goode 1Brandeis University, 2UCSB
Active materials are systems that are driven by nano scale components that consume energy and produce work. In this work, two new biochemically powered active materials were developed with unique properties that will allow for a systematic exploration of emergent non-equilibrium phenomenology.

Large Variations in Structure and Chemistry in the Near-Boundary Region
MJ McCarthy, D Apelian, WJ Bowman, H Hahn, X Pan, TJ Rupert, University of California, Irvine J Luo, SP Ong, University of California, San Diego
Grain boundaries, interfaces between two crystals inside a material, are important defects which can dramatically alter material response because the structure of the boundary is different from the bulk crystalline region.

Single-Defect Phonons Imaged by Electron Microscopy
Based on the new capabilities of the Nion HERMES 200, the UCI MRSEC team (Pan and Wu) demonstrated, for the first time, exotic atomic vibrations localized at a single stacking fault in cubic SiC, showing by an energy shift of 3.8 meV and an obvious intensity modulation of the acoustic phonon mode.

Hierarchical Assembly of Structurally Oriented Metal-Organic Frameworks as Novel Ionic Conductors
Chen, Pascal, Meng; University of California San Diego
Liquefied gas electrolytes enable low temperature operation due to their low freezing point. However, their high vapor pressure poses a safety concern. Can confinement of these gas electrolytes in a nanoscale material enhance electrochemical performance while minimizing the hazards?

Research Immersion in Materials Science & Engineering (RIMSE) Spring Break Research Experience
Brydges, Sailor; University of California San Diego
In response to a campus-wide initiative to prevent a surge in COVID19 infections, the Center piloted a special (in-person) RIMSE Spring Break Research Experience to encourage undergraduate students to remain on campus during the 2021 Spring Break.

Liquid-induced Topological Transformations of Cellular Microstructures
Joanna Aizenberg (Chemistry and MatSci) and Katia Bertoldi (MechE)
A team at the Harvard MRSEC led by Aizenberg and Bertoldi has developed a dynamic design strategy to achieve topological transformations of two-dimensional polymeric cellular lattices in a reversible and controllable manner through exposure to different liquids.

Mechanochemical Adhesion and Plasticity in Multifiber Hydrogel Networks
Matthew Davidson, Ehsan Ban, Vivek Shenoy, Jason Burdick, University of Pennsylvania
Burdick and Shenoy have designed synthetic actively remodeling networks using electrospun fibers containing reactive groups that form covalent crosslinks at sites where fibers are brought together by localized strains. This approach uses the fibers of hyaluronic acid modified with either hydrazides (red) or aldehydes (green).
