Participants from 23 institutions and companies joined the meeting in person on the Cornell campus and online via YouTube live.

An international collaboration of the Physics Department at Technical University of Munich has established a novel and versatile approach to fine-tune the morphology and hence the functionality of thin polymer films. Prof. Christine Papadakis and coworkers changed the nano-structure of these films by annealing the films at elevated temperature and with mixtures of two solvent vapors.

A cross-campus collaboration led by Ulrich Wiesner, the Spencer T. Olin Professor of Engineering in the Department of Materials Science and Engineering, addresses this demand with a novel energy storage device architecture that has the potential for lightning-quick charges.

These blended geographic features serve as a metaphor for the evolving college community, where Native American students and those of European descent have converged to obtain a higher education at Fort Lewis College, FLC, one of the top ranked public liberal arts institutions in the country.

MHPs are unique in that they combine low-cost solution processability with superb electronic quality that is comparable to, or surpasses, that of the state-of-the-art epitaxial grown semiconductors. What is particularly exciting about MHPs is that they can be manufactured into lightweight flexible solar cells that can provide power in locations that are difficult for traditional solar cells - drones, cars, soldiers and backpackers.

What did the Scientists Discover?

The outreach team visited the 8th grade classroom of physical science teacher, Anne Gleed, for a full week of demonstrations and activities. Demonstrations included current carrying wires and their effect on permanent magnets and looking at magnetic fields around permanent magnets with the help of iron filings. Activities included wrapping coils of wire (hooked up to a battery) that would “hop” when placed near magnets and looking at a loudspeaker that had been taken apart to spot the coil and permanent magnet inside.

In bacteria, this system is known as CRISPR (Clustered Regularly Interspaced Palindromic Repeats, see CHESS news item: Adaptive Immune Systems of Bacteria, 2012) and consists of RNA which recognizes and binds the foreign DNA or RNA through an RNA-mediated interference mechanism and a number of Cas (CRISPR-associated) proteins which help to either form the complex or to degrade the foreign DNA. The complex is known as CASCADE (CRISPR-Associated Complex for Antiviral Defense).

In the past, users performing electrochemical experiments at beamlines brought their potentiostats from their home laboratories. Because they are delicate, there is a risk of breakage of their internal components while transporting them, adding delays to users’ research programs if they do break. By having one at CHESS, users no longer need to bring one from their laboratories. There are several advantages of the Bio-Logic model. First, because of its portable design, it can easily be set up at different stations.

The octahedron itself can be composed of smaller particles located at the corners of the octahedron. Such binary structure of large iron oxide spheres of 13 nm diameter enclosing a hexamer of six small 4nm lead sulfide particles is known as an AB₆ binary superlattice.

Currently, the data that is collected at F2 and at F3/G3 (with the Maia detector) is being written directly to this new centralized data storage, and we plan to extend this system to other beamlines and detectors in future cycles. This data is accessible for analysis on the CLASSE compute cluster, and long-term archival storage is provided by an offsite magnetic tape library.
