2020 Research Highlights

Education & Outreach

The annual MRSEC student survey (with 57 respondents) highlighted several areas of interest, including science communication (70%), networking with industry (65%), interviewing for jobs (72%) and m

Education & Outreach

A five-day STEM Extension program in July 2017 provided ten blind or low-vision college-bound students with a full-access experience in college chemistry and physics labs as part of Summer Academy,

IRG1 - Layered Ferroics

The design of new or enhanced functionality in materials is traditionally viewed as requiring the discovery of new chemical compositions through synthesis.

IRG1 - Layered Ferroics

Systems that exhibit phase competition, order parameter coexistence, and emergent order parameter topologies consti

IRG2 - Nanomotors

The H2O2 powered bimetallic micromotors can respond to shear flow and exhibit rheotactic behavior.

IRG2 - Nanomotors

Enzymatic catalysis is essential to cell survival.

IRG3 - Metalattices

We synthesized nanoporous magnetic metalattices by high pressure confined chemical vapor deposition of nickel into silica sphere nanotemplates.

IRG4 - Phototonic Assemblies

Microscale photoresist posts were used to concentrate the electric field gradient generated by a vertically applied AC electric field.

IRG4 - Phototonic Assemblies

Vanadium dioxide (VO2) nanostructures that exhibit a switchable metal-insulator transition are difficult to synthesize in solution, in part because there are several closely related VOx 

2019 Research Highlights

The Penn State MRSEC partnered with Science-U summer camps to pilot a half-day STEM program for college-bound high school students who are blind or visually impaired.

IRG 2 - Nanomotors

Acoustics arrays can be used for imaging, directing the motion of particles, and (at high intensities) therapeutic applications.

IRG 2 - Nanomotors

The diffusivity of enzymes is enhanced when they are catalytically active, and it was suggested that this enhancement could be correlated to their exothermicity.

IRG 3 - Metalattices

We have synthesized large area, well ordered binary crystals composed of two different sizes of silica colloid spheres as small as 20 nm in diameter.

IRG 4 - Photonic Assemblies

Gold nanowire lattices were formed by electric field directed assembly and reconfigured on-demand between two different functional states, in the form of broadband polarizers.

IRG1 - Layered Ferroics

MRSEC researchers have developed an informatics-guided ab initio approach to accelerate the design and discovery of noncentrosymmetric materials, integrating group theory, informatics and density-f

IRG1 - Layered Ferroics

Layered complex oxides offer an unusually rich materials platform for emergent phenomena through many built-in design knobs such as varied topologies, chemical ordering schemes and geometric tuning

2018 Research Highlights

Education & Outreach

The Millennium Science Complex hosts user facilities including the Nanofabrication Lab, the Materials Characterization Lab, and the Materials Computation Center.

IRG 2 - Nanomotors

Coffee rings form during the evaporation of colloidal suspensions.

IRG 3 - Metalattices

The availability of high-quality semiconductors in fiber form could be transformative in the vision of all-fiber optoelectronics.

IRG1 - Layered Ferroics

The complex interplay of spin, charge, orbital and lattice degrees of freedom supports exotic physical phenomena.

IRG1 - Layered Ferroics

Transparent conductors are materials that are transparent in the visible spectrum and electrically conducting.

IRG4 - Photonic Assemblies

A dielectric mirror comprised of a cross-shaped amorphous silicon nanoresonator array was designed to achieve 99.8% reflectivity and zero reflection phase at the wavelength of 0.99 μm.

Seed

The discovery of the quantum Hall (QH) effect led to the realization of a topological electronic state with dissipationless currents circulating in one direction along the edge of a two dimensional
