Capillary forces and biomolecular condensates: Structure and function

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.

Unlocking High Capacity and Fast Na+ Diffusion of HxCrS2 by Proton-Exchange Pretreatment

Princeton researchers have demonstrated that acid pre-treatment of NaCrS2 to form a new phase (named HxCrS2) results in significant improvements to the material’s performance as a sodium battery electrode.

Proximity-induced superconductivity in epitaxial topological insulator/superconductor heterostructures

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

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.

Frustrated self-limiting assembly of trumpets

Triangular monomers with positive curvature in one direction and negative curvature in another assemble into trumpet shaped objects predicted to have precise self-limited lengths due to frustration-induced stress.

Active composite materials

Active composites obtained by merging   a   conventional   soft   matter actin    gel    with    energy    consuming microtubule   bundles   that   generate active   stresses   leads   to   emergent properties not present in the individual systems.

Exciton-Coupled Coherent Magnonsin a 2D Semiconductor

One exciting application of magnetic materials is the use of coherent magnonsas energy-efficient information carriers in spintronicsand magnonicsor as interconnects in hybrid quantum systems.

Ballistic Excitons and Surface Functionalization in a Superatomic Semiconductor

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

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.

A New Common Behavior for Glasses

Materials  scientists  use  rules  that  hold  across  different kinds   of  materials   as  powerful  tools  to  understand material’s    fundamental    behavior,    to    predict    their properties   and   performance,   and   to   design   new materials.
