IRG1: Metallic Antiferromagnetic Materials: Utrafast Charge, Lattice, and Magnetization Dynamics

The interdisciplinary research in IRG-MAX (Metallic Antiferromagnets and the eXcitations) is designed to advance understanding of the synthesis-structure-property relationships of metallic antiferromagnetic materials. Our key goal is to answer open questions concerning the coupling of magnetic order, optical fields, electronic excitations, and lattice vibrations that underlie fundamental limits on the control of magnetization dynamics using ultrafast optics, fast temperature excursions, and ultrafast currents of heat and charge.

IRG2: Active interfaces between highly deformable nanomaterials

The interdisciplinary team in IRG 2 seeks to address a grand challenge in materials research of bridging the electronic design capability of hard electronic materials with the soft, adaptive and three-dimensional nature of biology. Our strategy is to utilize two-dimensional materials, which have similar stiffnesses to biological membranes like lipid bilayers, yet have diverse electronic properties allowing the construction of fully-functional electronic devices at nanometer length scales.

Seed: Printed 2D Nanostructured Bioactive Electronics for Seamless Integration with Functional Biomaterials

A grand challenge in the field of bioelectronics is to develop soft, deformable, and adaptive materials with a wide range of functionality. In order to address this challenge, new electronic materials need to be invented to closely mimic the mechanical properties (e.g. modulus) of biological membranes and tissues. Moreover, new chemistries and functionalities are critically required to generate intimate and robust bio-electronic interfaces between traditionally disparate materials.

Seed: Modulating Electrocatalytic Activity across 2D Electrodes by Exploiting Atomic-Scale Interactions

The seed effort carried out by the groups of Rodríguez-López and Bhargava will address a new concept in electrocatalyst design that utilizes ultra-thin 2D electrodes as electronically-transparent substrates, Figure 1. The purpose is to enable unprecedented catalyst-catalyst interactions at atomic scales via the resulting heterostructure for exploring new strategies to control interfacial electrochemical reactivity.
