2013 Research Highlights

IRG 1 - Strain-Enabled Multiferroics

Penn State MRSEC IRG1-TEAM (Strain-enabled multiferroics), in close collaboration with Cornell MRSEC, U Maryland, NIST and others, has designed and demonstrated the world’s best tunable microwave d

IRG 2 - Powered Motion on the Nanoscale

A crack in a high mineral-content material, like bone or a synthetic mineral/polymeric composite, generates ion gradients which can be utilized for active targeting and repair.

IRG 3 - Electrons in Confined Geometries

A thin aluminum wire is contacted by 4 wider electrodes, as shown at left.

IRG 4 - Electromagnetic Nanostructures

John V. Badding and co-workers demonstrate on p. 1461 the ability to fabricate silicon p-i-n junctions within high aspect ratio optical fibers, and which exhibit photovoltaic response.

Center Diversity

The Penn State MRSEC has recognized that, in order to further increase the diversity of our own Center participation, we need to target institutional-level change by addressing pipeline issues of r

Education and Outreach

The Franklin Institute (a science museum in Philadelphia) and the MRSEC have been engaged in a longtime partnership which most recently resulted in a 5th museum show kit called Pocket Tech.

IRG 1 - Strain-Enabled Multiferroics

Piezoelectric materials convert electrical to mechanical energy.

IRG 2 - Powered Motion on the Nanoscale

Patterning of nanowires in a controllable, tunable manner is important for the fabrication of functional nanodevices.

IRG 2 - Powered Motion on the Nanoscale

Following the discovery (ACS Nano 2012, 6, 6122) of bio-compatible, acoustically powered nanorod motors, MRSEC researchers have collaborated with scientists at ESPCI (Paris Tech) and NIST to study

IRG 2 - Powered Motion on the Nanoscale

A Y-shaped microfluidic device generates a gradient in the concentration of “substrate,” the fuel for an enzyme.

IRG 2 - Powered Motion on the Nanoscale

Silver phosphate micromotors exhibit reversible transition between two collective behaviors: repulsive dispersion-like “exclusion” and attractive clustering-like “schooling” by the addition and rem

IRG 2 - Powered Motion on the Nanoscale

We recently developed small molecule reagents that can be grafted onto polymer beads or surfaces to create a variety of smart pumps.

IRG 4 - Electromagnetic Nanostructures

Chemical vapor deposition (CVD) is a mainstay of the semiconductor industry. Films of materials useful for chips, solar cells, displays, window coatings etc.
