  • Kleiner develops method to profile RNA-modifying enzymes

    Monday, Oct 4, 2021
    by Wendy Plump, Department of Chemistry

    Using a largescale approach to studying cellular proteins called chemoproteomics, Ralph Kleiner, assistant professor in the Department of Chemistry, has developed a methodology that provides insights into a cell’s RNA modifications and their associated enzymes, expanding our knowledge of the workings of this central biomolecule. 

  • Princeton chemists discover a key to greener food production

    Arguably the most important (if least well known) industrial advancement of the 20th century, the Haber-Bosch ammonia synthesis process essentially conquered food scarcity by creating the means to mass produce fertilizer — fertilizer then used to fortify food harvests around the world.

  • Magnetic ‘balding’ of black holes saves general relativity prediction

    Tuesday, Jul 27, 2021
    by Thomas Sumner, Simons Foundation

    Magnetic fields around black holes decay quickly, report researchers from the Flatiron Institute, Columbia University and Princeton University. This finding backs up the so-called ‘no-hair conjecture’ predicted by Einstein’s general relativity.

  • Balloon-borne telescope is set to launch to study dark matter

    A team of researchers from Princeton University, the University of Toronto and Durham University in England with NASA and the Canadian Space Agency have designed a new telescope called the Superpressure Balloon-borne Imaging Telescope, or SuperBIT.

  • Schoop lab designs, probes new Dirac semimetal

    by Wendy Plump, Department of Chemistry

    In research that draws on expertise from both chemistry and physics to deepen our understanding of the properties of topological matter, the Department of Chemistry’s Schoop Lab introduces a mechanism to design an idealized Dirac semimetal of a new kind.

    The new strategy designs clean nonsymmorphic Dirac semimetals, allowing researchers to uncover electronic behaviors that had been theorized but not previously demonstrated because of interfering states or “noise” surrounding the preferred electronic state. 

  • New evidence for electron’s dual nature found in a quantum spin liquid

    Thursday, May 13, 2021
    by Catherine Zandonella, Office of the Dean for Research

    A new discovery led by Princeton University researchers could upend our understanding of how electrons behave under extreme conditions due to the laws of quantum physics.

    The finding provides experimental evidence that this familiar building block of matter often behaves as if it is made of two particles — one particle that gives the electron its negative charge and another that gives it a magnet-like property known as spin.

  • Women's History Month: Engineering faculty and alumnae reflections

    Wednesday, Mar 31, 2021
    by Molly Sharlach, Office of Engineering Communications

    For a half century, women have played leading roles in research, teaching and innovation at Princeton’s School of Engineering and Applied Science. Today, engineering faculty also include women who completed their graduate or undergraduate degrees at Princeton. Spanning different disciplines and generations, each of them has made outstanding contributions in her respective field, and each exemplifies Princeton’s traditions of fundamental research and engineering in the service of humanity.

  • Princeton chemists grapple with 'Karma'

    Thursday, Mar 25, 2021
    by Wendy Plump, Department of Chemistry

    It turns out there is such a thing as a “karma” machine, and it lives on the ground floor of Frick Laboratory.

    The high-pressure, high-temperature furnace weighs 12,000 pounds, exerting as much pressure in a corner of the lab as three cars stacked on their noses. It’s the same age as some of the researchers working with it. It occasionally stops working for no discernible reason. And it requires fine motor skills and a surfeit of good cheer to keep it running.
