Program Highlights

Designing the flow properties of concentrated particle suspensions

In a concentrated suspension of small solid particles in a liquid under shear, a large number of dynamically evolving particle-particle and particle-liquid interfaces controls the overall flow properties.

Wafer-scale synthesis of monolayer two-dimensional porphyrin polymers

At the University of Chicago MRSEC, Park and Sibener developed a synthesis of two-dimensional (2D) polymers with wafer-scale homogeneity, one monolayer thick, using a general and scalable growth method called laminar assembly polymerization.

CDCM is Creating Informal, Accessible K-12 Education for All Students

The CDCM Stuff program engages diverse young learners and public audiences in the beauty, excitement, and impact of materials science and materials-based technologies. CDCM has facilitated 39 events during this reporting period, impacting more than 2,300 community participants.

Pure Spin Current in a Non-Equilibrium Magnetic Insulator

We investigate spin current in a magnetic insulator, YIG, under thermally driven  non-equilibrium conditions, a challenging task for conventional transport techniques. 

Chemically-Triggered Synthesis, Remodeling, and Degradation of Soft Materials

This works demonstrated a series of morphological changes could be induced with a small set of monomers due to the use of reversible covalent bonding interactions.

Unique Facilities: Benchtop X-ray Spectrometer for Accelerating Discovery and Characterization of Novel Phosphorous-Rich Materials

MEM-C has developed a unique high-resolution x-ray emission spectrometer for studying phosphorus-rich, air-sensitive materials.

MEM-C IRG-2: An atomically thin in-plane layered antiferromagnetic insulator

We investigate the magnetic order of atomically thin CrCl3 by employing vertical tunneling measurements, which are sensitive to the relative alignment of spins in different layers. 

I-MRSEC educational web series: “Magnetic Fields”

In Summer 2019 the I-MRSEC officially released the web series “Magnetic Fields,” which follows middle school aged characters as they encounter a new material at the I-MRSEC, and emphasizes the scientific process, persistence, and the diversity of scientists.

Ultrasoft, Slip Mediated Bending of Multilayer Graphene

Two-dimensional (2D) materials like graphene are highly deformable due to their atomically thin structure. To fabricate deformable devices (e.g. flexible and wearable electronics) that capitalize on their ultrasoft nature, it is critical to assess the bending stiffness of graphene.

Discovery of a hexagonal easy-plane metallic antiferromagnet in the CuMnAs system

We discovered a new hexagonal metallic antiferromagnetic phase in the Cu-Mn-As system.   Electrical switching and read-out of tetragonal CuMnAs inspired a world-wide research effort in metallic antiferromagnets. Phase equilibria in this system (Fig. a) however is poorly understood.
