Program Highlights

Discovery of bilayer nanoparticle (NP) superlattices using global Monte Carlo optimization

IRG1 has developed a computational framework for understanding how nanoparticles (NPs) assemble at the  interface  between  two  immiscible  fluids.

Where Materials Begin and Society BenefitsFirst Demonstration of Controlled Grafting-from ROMP Bioconjugates

This  is  the  first  demonstration  of  living ring  opening  metathesis  polymerization (ROMP) from a biological substrate.

Genetic Fusion of Thermoresponsive Polypeptides Mediates 1-D Assembly of Coiled Coil Bundlemers

The ability to thermally trigger a conformational changeand collapse in a constituent resilin-like protein (RLP) providesthe opportunity to build, and eventually move, a bundlemer nanostructure.

Bi2Se3 Growth on (001) GaAs Substrates for Terahertz Integrated Systems

This work demonstrates that the TI vdW material Bi2Se3 can be grown as a single-crystalline single-orientation film on semiconductor substrates with appropriate substrate pre-treatment conditions.

An efficient material search for room-temperature topological magnons

IRG-2 developed a symmetry-based approach that uses only few inputs, to carry out an efficient yet systematic search for topological magnons in magnetic insulators. Robust against disorders and decoherence, they serve as potential platforms for magnon-based spintronic devices.

Strengthening Networks: Connecting MRSEC and PREM Students with Academic and Industry Representatives

The Ohio State University and University of California, Santa Barbara MRSECS  partnered  to  host  the  Conference  Across  MRSECs  and PREMs (CAMPS) in October 2022.

Core-Shell Gyroid in ABC Bottlebrush Block Terpolymers

A  principal  obstacle  to  widespread  applications  of  self-assembled network morphologies (NETs) of linear block polymers is access to only limited pore diameters and unit cell dimensions (typically <50 nm),  originating  from  their  coil  configurations  and  slow  self-assembly  kinetics  at  high  molar  masses.

Ferroelectric Superconductivity in a Transition Metal Dichalcogenide

For the first time, a team comprised of two IRG-1 theorists (Birol  and Fernandes) working with experimentalists from other institutions (including  the  Columbia  MRSEC) showed the  coexistence of ferroelectricity (i.e.,  electrostatically switchable macroscopic dipole moment) and superconductivity in a two-dimensional superconductor.

Partnership in Research and Education in Materials with Navajo Tech: Inspiring STEM Pathways from High School to Graduate Studies

The  Partnership  for  Research  and  Education  in Materials  between  Navajo Technical  University  and the   MRSEC   based   at   Harvard   focuses   on developing culturally-informed, sustainable pathways into materials science-related careers and advanced studies  for  Navajo  students.

Inverse Design of Mechanical Metamaterials with Target Nonlinear Response via a Neural Accelerated Evolution Strategy

A team at the Harvard MRSEC led by Bertoldi and Rycroft  has  developed  a  framework  to  design mechanical  metamaterials  with  target  nonlinear response. Neural networks were used to accurately learn  the  relationship  between  the  geometry  and nonlinear   mechanical   response   of   these metamaterials.
