Active Control of Long-Range Exciton Transport in Superatomic Materials
Milan Delor, Columbia University Center for Precision-Assembled Quantum Materials (PAQM)
Active control over exciton (electron-hole pair) transport is a much sought-after goal to create reconfigurable excitonic and optoelectronic transistors. The PAQM team achieved the first example of predictive optical control over exciton transport in semiconductors.

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?
