Assembly of Linked Nanocrystal Colloids by Reversible Covalent Bonds

This highlight demonstrates the combination of colloidal nanocrystals with uniquely developed ligands for the use of gelation assembly. Through this combined experimental, computational and theoretical work provided a platform for controlling and designing the properties of reversible colloidal assemblies.

Collective Excitations in Twisted Bilayers

Moire superlattices consist of two monolayers of atomically thin materials, in this case the transition metal dichalcogenide MoS2, stacked on top of each other with a slight rotational misalignment (twist) that creates a moire interference pattern between the atomic lattices of the two monolayers.

Seed: Selecting for Phase-Separating Nucleic Acid Coacervates

Top: Designed DNA structures of varying charge density and flexibility. Bottom left: Coacervate droplets formed from 1 DNA structure. Bottom middle/right: Binary droplets formed from a model system with 2 DNA structures.

IRG-3: Accelerating Block Copolymer Research

A single parent diblock copolymer can be purified by automated chromatography to give libraries of well-defined, low dispersity block copolymers on multi-gram scale.

IRG-1: Magnetoplastic Coupling in Heusler Intermetallics

Experiments (top) showing near zero-net magnetization of MnAu2Al following plastic deformation and simulations (bottom) of low energy displacive pathways enabled by local spin orderings.

UC Santa Barbara MRSEC Continues REU Program Through COVID-19 Lockdown

The UC Santa Barbara ran a fully remote REU program in Summer 2020, with 18 students working on primarily computational projects.

Tiny Robots with Giant Potential (TED Talk)

Take a trip down the microworld as roboticists Paul McEuen and Marc Miskin explain how they design and mass-produce microrobots the size of a single cell, powered by atomically thin legs -- and show how these machines could one day be "piloted" to battle crop diseases or study your brain at the level of individual neurons.

NYU-MRSEC & BioBus Collaboration

NYU-MRSEC investigators have worked alongside BioBus scientists to develop new K-12 materials science-related curricula since 2009. This collaboration brought exciting and educational engineering projects to over 1,000 NYC students in 2019-2020.

Voltage Control of Magnetism above Room Temperature in epitaxial SrCo1-xFexO3-δ

Searching for new materials and phenomena to enable voltage control of magnetism and magnetic properties holds compelling interest for the development of low-power non-volatile memory devices. Here, we report on a non-volatile ON/OFF voltage control of magnetism in thin films of an oxide, SrCo1-xFexO3-δ (SCFO).

Manipulating Solid Forms of Contact Insecticides for Infectious Disease Prevention

MRSEC investigators rediscovered DFDT and found that amorphous and crystalline forms of DFDT and a mono-fluorinated chiral congener, MFDT were more active against Anopheles and Aedes mosquitoes, the former the disease vector for malaria and the latter for Zika, yellow fever, dengue, and chikungunya.
