Younger scientists often ask him about exploring multiple fields, Balasubramanian says. The advice he offers is to “have a central line where you have credibility, where you’ve established that you’re really, really good at what you do, and you can be trusted.”

Sliski's composite image of the solar eclipse, with plumes located above and below the poles of the stars, red prominences located near the edge of the sun (at 11 and 8 o'clock), and with one extensions each to the east and west of the solar disc. This data will be compared to predictive models to better refine the current understanding of the sun (Image credit: David Sliski). 

Randall Kamien of the School of Arts & Sciences and long-time collaborator Geneviève Dion, a professor of design at Drexel University, are investigating the mechanics of knitting, an area of research that represents a significant shift in understanding and using fabrics.

A collaborative team of researchers led by Bo Zhen of the School of Arts & Sciences have created new materials by artificially twisting and stacking two-dimensional atomic “sheets.” New materials control light-matter interaction differently from constituent 2D atomic sheets, paving the way for next-generation laser, imaging, and quantum technologies.

A collaborative team of researchers led by PIK Professor Christopher B. Murray has observed for the first time composite superstructure growth from nanocrystals in real time. The discovery could enable engineers to more reliably manufacture next-generation materials by combining different nanocrystals. Shown here is an artist's impression of spherical binary nanocrystal superlattices featuring semiconductor (emissive) and magnetic/plasmonic (non-emissive) nanocrystals.
