MEM-C IRG-1: Patterning Nanocrystals on Photonic Cavities with Electrohydrodynamic Inkjet Printing

Devin MacKenzie, Daniel Gamelin, Christine Luscombe, Jim De Yoreo, Arka Majumdar

Electrohydrodynamic ink jet printing has been used to print  CsPbBr3 nanocrystals into very small features, with spot sizes down to only a few hundred nanometers across. The nanocrystals survive the printing, and even spontaneously self-organize into superlattices.

Capillary forces and biomolecular condensates: Structure and function

Bernardo Gouveia1, Yoonji Kim1, Joshua W. Shaevitz1, Sabine Petry1, Howard A. Stone1 and Clifford P. Brangwynne1 1 Princton University

Princeton researchers have demonstrated the physical principles of capillarity, including examples of how capillary forces structure multiphase condensates and remodel biological substrates. As with other mechanisms of intracellular force generation (e.g. molecular motors), capillary forces can influence biological processes. Identifying the biomolecular determinants of condensate capillarity represents an exciting frontier, bridging soft matter physics and cell biology.

Proximity-induced superconductivity in epitaxial topological insulator/superconductor heterostructures

Zhu, Chang, Robinson, Hickey (PSU), Oreg (Weizmann Inst. of Sci.)

The search for an unusual form of superconductivity known as topological superconductivity has attracted a great deal of attention of the quantum materials community because of its fundamental novelty and potential applications in fault-tolerant quantum computing technology.

Electrocaloric Effect of Perovskite High Entropy Oxide Films

Y. Son and Susan E. Trolier-McKinstry, Penn State University

Pb(Hf0.2Zr0.2Ti0.2Nb0.2X0.2)O3, a high-entropy perovskite, undergoes an entropy-driven phase transformation when X=Mn while X=Al always contains minor second phases in bulk ceramics.

Ballistic Excitons and Surface Functionalization in a Superatomic Semiconductor

Roy, Delor, Nuckolls and Berkelbach, Columbia University

The transport of energy and information in semiconductors is limited by scattering between electronic carriers and lattice phonons, resulting in diffusive and  lossy  transport  that  curtails  all  semiconductor  technologies.

Highly Oriented Glassy Thin Films of Organic Semiconductors

Paul Voyles, Mark Ediger, Lian Yu, University of Wisconsin-Madison

Textbooks say that glasses are structurally disordered and  isotropic,  meaning  that  their  constituent molecules don’t’ form a repeating pattern and point in random directions.
