Defects, essentially locations in a crystal where the perfect arrangement of atoms is disturbed, are inherent in materials, and play a key role in their function.

Solution-processed semiconductor and dielectric materials are attractive for satellite technology due to their light-weight, low-voltage operation, and mechanical robustness, but their response to ionizing radiation environments is not well understood.

Nebraska MRSEC sponsored and organized Science Night Live!, a unique event that created opportunities for Nebraska scientists to engage the general public with science in ways that challenged stereotypes about who scientists are, how science is done, and why basic research is valuable. 

IRG1 of the Columbia MRSEC seeks to understand the behavior of van der Waals heterostructures created by assembly of atomically thin layered materials. One important question in this effort is how the relative orientation between the layers affects multiple properties.

Due to enormous challenges associated with theoretical modeling of multicomponent alloys, there are no reliable theoretical predictions available for their composition-dependent properties and structures. Taylor and Schroers have proposed to use combinatorial materials science to address this challenge. 

Restacked films of exfoliated 2D nanosheets can function as massive nanofluidic channel arrays. Recent research shows that cutting such membranes into asymmetric shapes leads to ionic current rectification.

A Solar Outreach Program for Haiti is comprised of an interdisciplinary team of students, professors, university partners, and non-governmental organizations whose goal is to design and build Integrated Energy Centers in energy scarce regions. This year, the program developed a business plan, located investors, and submitted several grant proposals.

Finely patterned surfaces, known as metasurfaces, can control light with unprecedented ability. Unlike traditional optical elements, metasurfaces derive their optical properties from their subwavelength texture rather than their shape.

On April 8, 2017, PCCM held its first Día de la Ciencia at the Princeton Public Library. Forty scientists set up 20 table presentations and met with over 500 members of the community. In an attempt to improve outreach to all members of the community, PCCM organized the Día de la Ciencia event to reach the large Latino/Latina population in the town of Princeton, NJ and surrounding region. PCCM piloted Día de la Ciencia with science demos and had at least one Spanish speaking presenter at each table.

Graphene is a two-dimensional material that consists of carbon atoms arranged in a hexagonal lattice. Graphene has a very high electronic conductivity that could be tuned by external electric field.
