Materials Sciences and Engineering Research Highlights

Robust pressure correction for piston-cylinder cells

The temperature- and pressure-dependence of the resistance of manganin wire was determined for use as a manometer.

Elucidating electron spatial confinement in 2-d materials

In situ growth and metal adsorption experiments confirmed the broad bell-shaped component (BSC) of the broad diffraction background results from electron spatial confinement.

Assembling and Orienting Anisotropic Nanostructures

Nonspherical nanostructures were assembled to form 2D and 3D structures via functionalized polymers.

Cuckoo-Inspired, Fast Model Design of High-Entropy Alloys

We accelerate computational design of high-entropy alloys with targeted disorder by ultrafast model generation using a metaheuristic Hybrid Cuckoo Search (CS).

Light induced Weyl semimetals with exceptional ballistic transport

Topological phase transitions may be controlled by a coherent light-induced phononic symmetry switch, without the application of static electric or magnetic fields.

Linking local structure order in metallic glass and competing crystalline phases

Short- and medium-range orders in Al90Tb10 glass are shown to be similar to structures of competing crystalline phases.

Critical role of electron correlations on exchange interactions and spin excitations

Including nonlocal electron correlations in electronic structure calculations yields spin excitations consistent with inelastic neutron-scattering measurements in CrI3.

Determining the Edge Termination of h-BN Nanosheets

Hexagonal boron nitride nanosheets, an isoelectronic analog to graphene, are of interest due to their 2D structure, high thermal oxidative resistance, high bandgap, catalytic activity and low cost.
