UT Austin MRSEC researchers show that ferroelectric polar domains formed in a twisted hexagonal boron nitride (t-hBN) substrate can modulate light emission from an adjacent semiconductor monolayer. The abrupt change in electrostatic potential across the domains produces an in-plane electric field (E-field) and leads to a remarkably large exciton Stark shift in the adjacent MoSe2 monolayer, previously only observable in p-n junctions created by the advanced e-beam lithography tools. Both the spectrum and spatial pattern of the light emission of the monolayer are periodically modulated by the remote moire potential imposed by the t-hBN substrate.

This study by UT Austin researchers demonstrates the rich electronic structures in large-angle twisted bilayer WSe2 exemplified by the formation of multiple mini-gaps near the valence band maximum. By tuning the commensurability, the moiré material properties and functionalities can be precisely engineered.

UT Austin researchers developed synthetic multi-arm poly(ethylene glycol) (PEG) hydrogels with three different dynamic covalent linking chemistries. They exhibit non-monotonic flow curves under steady shear, with shear thickening behavior that depends on the crosslinking bond exchange kinetics and polymer concentration.

  Professor Gerd Ceder, co-leader of the MIT battery IRG, and MRSEC-supported graduate student ByoungWoo Kang wanted to dispel the myth that batteries have low power rates.

Engineering Transdisciplinary Outreach Program in the Arts (ETOPiA) is a Northwestern University MRSEC education and outreach program that uses theater and film media to inspire a cross-disciplinary dialogue about the role of science and technology in society and to highlight some of the ethical and moral implications of scientific and technological progress.

Optical properties of plasmonic ITO nanocrystal gels, assembled by thermoreversible cobalt terpyridine links, were tuned systematically based on the size and doping concentration of the nanocrystals and length of the custom ligand molecules. Correlation of optical shifts upon assembly with nanocrystal spacing deduced by small angle X-ray scattering was used to develop a universal structure-property relationship that was validated by large-scale optical simulations on gels made using Brownian dynamics simulations.

Two-dimensional materials offer a unique opportunity to explore superconductivity in the two-dimensional (2D) limit with low disorder.  IRG1 creates heterostructures of high-quality monolayers of superconductors encapsulated within insulating boron nitride, which provides protection from external disorder and oxidation.

Infection by adenovirus is initiated when Knobs (globular protein domains) on the virus periphery bind to a CAR (Coxsackie-Adenovirus Receptor) membrane protein of the host cell.

UC San Diego researchers developed and programmed cyanobacterial composite materials to remediate an organic dye pollutant. 

Nebraska MRSEC researchers have fabricated complex oxide heterostructures with atomic precision, exploiting them to build a prototype nonvolatile Mott transistor.
