Building strongly interacting photonic materials

Ruichao Ma (University of Chicago) Brendan Saxberg (University of Chicago) Clai Owens (University of Chicago) Nelson Leung (University of Chicago) Yao Lu (University of Chicago) Jonathan Simon (University of Chicago) David I. Schuster (University of Chicago)
A collaboration of the Simon and Schuster groups at the University of Chicago MRSEC  have realized a photonic strongly interacting Mott insulator using a 1D lattice of superconducting qubits.

Subatomic Channeling and Spiraling Electron Beams in Crystals

K. Andre Mkhoyan, University of Minnesota
Using analytical aberration-corrected scanning transmission electron microscopy (STEM), we studied the behavior of the electron probe propagating in SrTiO3 at sub-atomic length scales.
(Top) Cationic micelles can be formed via self-assembly from amphiphilic block polymers and complexed with pDNA to form micelleplexes. (Bottom) The number of micelles per micelleplex was estimated using the Mw of the micelleplexes measured by SLS with the assumptions that all micelleplexes are identical and that there are no excess free micelles.

ABC Micelleplexes: Precise Compaction and High Colloidal Stability

Timothy Lodge and Theresa Reineke, University of Minnesota
In this work, the complexation of ABC micelles with a model semiflexible polyion, DNA, is systematically investigated to correlate the structure of the micelle with the properties of the resulting “micelleplexes”.

NSF-MRSEC Booth at the International Materials Research Congress

The NSF-MRSEC booth was featured at the XXVII International Materials Research Congress (IMRC) in Cancun, Mexico on August 19-24, 2018 to increase awareness, promote international collaboration, and broaden participation from traditionally underrepresented groups in the National Science Foundation Materials Research Science and Engineering Center (NSF-MRSEC) program.

Joint Undertaking for an African Materials Institute (JUAMI)

The NU-MRSEC has supported Joint Undertaking for an African Materials Institute (JUAMI), which is the largely NSF-funded program aimed at fostering connections between young researchers in the US and those in Eastern Africa.

Research Experience for Undergraduates Plus (REU+)

The new NU-MRSEC REU+ Program enables select REU participants from small colleges to follow their summer experience with an academic quarter at Northwestern University as domestic exchange students, thereby allowing them to experience the rigor of an R1 university in a nurturing environment. REU+ students take classes and also continue their research for an additional ten weeks.
The updated Materials Science Exhibit is currently housed at the Harold Washington Library in downtown Chicago, which is the primary resource for the socioeconomically diverse Chicago Public Schools.

Designing Biomaterials Using High-Throughput Directed Evolution

Traditional design approaches are insufficient for exploring the vast phase space available to protein-based biomaterials. This NU-MRSEC seed-funded project is developing a platform for biomaterials design using directed evolution, which combines genetic mutation and protein synthesis with high-throughput materials characterization.

Processing 2D Porous Polymers into Membranes via Exfoliation

The NU-MRSEC Super-Seed team has developed a method to process imine-linked 2D COF powders into thin films via reversible exfoliation. The COF powder is treated with strong acids, which causes each layer to become positively charged. This charged form is exfoliated in solvents with gentle sonication, which provides a suspension of nanosheets.

Photoluminescence and Antiferromagnetism in the New Heteroanionic Material BaFMn0.5Te

Semiconductors with both magnetic and optoelectronic properties are relevant for novel spintronic devices. With the aim of discovering new magnetic semiconductors, NU-MRSEC IRG-2 performed synthesis investigations on mixed halide-chalcogenides, resulting in the discovery of the new compound BaFMn0.5Te.
