Block polymers are a class of versatile self-assembling soft materials that can form exquisite nanostructures for applications including ion transport membranes for batteries and fuel cells, and templates for inorganic oxide catalysts.

Atomically-thin sheets of semiconductors have been of immense interest since the Nobel-Prize-winning discovery of graphene or two-dimensional (2D) carbon. Such materials represent the ultimate limit of “scaling” to small sizes, of vital importance in the semiconductor device industry.
Fifty years of Moore’s Law scaling in microelectronics have brought remarkable opportunities for the rapidly-evolving field of microscopic robotics. Electronic, magnetic, and optical systems now offer an unprecedented combination of complexity, small size, and low cost, and could readily be appropriated to form the intelligent core of microscopic robots.
When an electrically-insulating material is grown on top of another insulator, the interface between the two insulators can be populated by mobile electrons. This has been achieved in interfaces that have a polarization discontinuity, such as AlGaN/GaN and LaAlO3/SrTiO3.
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.
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.
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.
We investigate spin current in a magnetic insulator, YIG, under thermally driven non-equilibrium conditions, a challenging task for conventional transport techniques.
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.
MEM-C has developed a unique high-resolution x-ray emission spectrometer for studying phosphorus-rich, air-sensitive materials.
