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 twist on atomic sheets to create new materials
A collaborative team of physicists in the School of Arts & Sciences have found that putting a twist on tungsten disulfide stacks illuminates new approaches to manipulate light.
Joe Romm, a senior research fellow in the School of Arts & Sciences’ Penn Center for Science, Sustainability, and the Media, has recently published two papers on carbon dioxide removal and bioenergy carbon capture and will be keynoting American University’s Third Annual Conference on Carbon Dioxide Removal Law & Policy: Carbon Removal Deployment: Law and Policy from Planning to Project.

Carbon capture and common misconceptions: A Q&A with Joe Romm
In a conversation with Penn Today, Joe Romm casts a sobering light on “solutions” to curb
climate change.
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.

Leveraging the body’s postal system to understand and treat disease
An interdisciplinary team of researchers in the School of Engineering and Applied Science, Perelman School of Medicine, and School of Arts & Sciences has developed a technique that allows for characterization of both individual carrier and cargo for clinically important molecules.
Michel Koo of the School of Dental Medicine and David Cormode of the Perelman School of Medicine and the School of Engineering and Applied Science led a team of researchers that uncovered a way to combine two FDA-approved treatments to treat tooth decay that taps into the blend’s bacteria-killing capabilities without disrupting the mouth’s microbiome.

Neanderthals carried genes acquired from ancient interactions with ‘cousins’ of modern humans
A new collaborative study led by Sarah Tishkoff shows that Neanderthals inherited at least 6% of their genome from a now-extinct lineage of early modern humans.
PIK Professor Michael Platt and collaborators have generated the first single-cell “atlas” of the primate brain to help explore links between molecules, cells, brain function, and disease.

Quantum dots are not just any nanoparticles. Often described as artificial atoms, these nanometer-sized semiconductor crystals possess unique attributes largely governed by their size, which chiefly dictates how they interact with light.
