Electronic nematicity, the spontaneous breaking of crystalline rotational symmetry, has been discovered in several strongly correlated electronic systems, including high Tc superconductors. Recently, several studies have suggested that the charge density wave in the kagome superconductor CsV3Sb5 breaks rotational symmetry—an intriguing possibility, as it would be a rare example of “three-state Potts nematicity,” in which there are three possible orientations in a hexagonal lattice. Here, we report that  CsV3Sb5 is probably not nematic, but it is very sensitive to isotropic strain.

Dendrimers are branched molecules of precise chemistry, and Janus-dendrimers are dendrimers that have two distinct faces, with unique chemistry corresponding to each face. Here, we made a library of carbohydrate containing glycodendrimers (GD) that self assemble into vesicles – a structure that mimics biological materials such as viruses. We show the vesicles have the ability to agglutinate lectin proteins at vesicle walls, owing to the chemistry and concentration of the carbohydrate.  Synthesis of these materials is the first step in the assembly of a synthetic virus.

Field-effect transistor (FET)-based biosensors allow label-free detection of biomolecules by measuring their intrinsic charges. We previously reported the extremely low limit of detection on electrical field effect-based sensors using crumpled graphene. Here, we use FETs with a deformed monolayer graphene channel for the detection of various biomarkers.

How can we wrap a 3d object with a sheet of paper without folds? Wrapping implies the ability to stretch as much as bend.  Using concepts from fractal geometry, we have designed and realized a new class of materials with unprecedented control of stretchability and bendability to conformally wrap any shape or expand to nearly any predetermined shapes.   Fractal cut sheets for controlled expansion

Terminator 2 is widely remembered for its metal shape-shifting villain. Impervious to bullets, explosives, and fire, theT-1000 robot was capable of changing shape at will. Researchers at the North Carolina State University have taken a step towards making science fiction a reality by developing a technique for controlling the surface tension of liquid metals using very low voltages. This technology paves the way for shape-reconfigurable metal components in electronic, electromagnetic, and microfluidic devices.

Monolayer molybdenum disulfide (MoS2) is a 3-atom thick material with a direct band gap, making it of interest for fundamental science as well as applications in optoelectronics and chemical sensing. Our innovation is a scalable method for “seeded growth” of high quality monolayer MoS2 at controlled locations, which is an important advance towards useful applications of the material.

Existing high-resolution neural recording devices cannot achieve simultaneous scalability on both spatial and temporal levels due to a trade-off between sensor density and mechanical flexibility. A team led by Liu, Bertoldi, Kozinsky, and Suo has introduced a 3D stacking implantable electronic platform, based on perfluorinated dielectric elastomers and tissue-level soft multilayer electrodes, that enables spatiotemporally scalable single-cell neural electrophysiology.

Researchers at OSU's Center for Emergent Materials have discovered that in semiconductors, specifically Indium Antimonide (InSb), heat can be controlled magnetically, given a sufficiently large magnetic field.

In collaboration with the Chicago Museum of Science and Industry, HerStory is an outreach event that encourages young girls, particularly underrepresented minorities, to pursue science in academia and beyond. The event agenda includes a massive scavenger hunt at the museum that featured exhibits of famous female scientists in each wing of the museum. Volunteers and young women from across the Chicagoland area participated in the event.
