February 2015: A first-of-its-kind electron microscope, which will allow materials to be studied in their natural environments using an electron beam focused down to a subatomic spot, is coming to Cornell.  An NSF grant was awarded to an interdisciplinary team led by KIC member Lena F. Kourkoutis. Read more in the Cornell Chronicle.

To better understand topological insulators (TIs) and why they weren’t living up to their potential Seamus Davis’s group at Cornell and Brookhaven National Lab studied them with their scanning tunneling microscope. What they found is the magnetic disorder at the surface was preventing the smooth flow of electrons.

January, 2015: KIC member J.C. Seamus Davis teams up with Eun-Ah Kim to isolate a ‘fingerprint’ that identifies specific fluctuations in electrons that force them into pairs, causing their host material to make way for free-flowing, resistance-free electron pairs.  Their findings were published in Nature Physics.  Read more about this work in the Cornell Chronicle.

ralph spin torqueKIC member Dan Ralph has partnered with Penn State researcher Nitin Samarth to discover a novel approach to computer memory they call a “topological insulator.” Using the spin orientation of electrons their approach could lead to memory devices that are 10 times more efficient than any other known methods. This discovery was described in the July 24 issue of Nature.  Read more in Science Codex.

Atoms of molybdenum (gray) and sulfur (yellow) are shown in a two-dimensional crystal formation. A laser hits the surface in a spiral, causing a valley current carried by an electron-hole pair, to move through the crystal.June, 2014: KIC members Paul McEuen, Jiwoong Park and Kin Fai Mak have tested molybdenum disulfide as a new semiconductor material, with the potential to create smaller, more efficient computers. Read more in the Chronicle and the June 27th article in Science.

On a cancer cell, long glycopolymers result in an expanded membrane-extracellular matrix gap, clustering of integrins and membrane bending. These physical effects lead to cell signaling pathways for enhanced cell survival.June, 2014: Matthew Paszek, KIC Fellow and Assistant Professor of Chemical and Biomolecular Engineering, led an important study on glycoprotein-induced cancer survival, published in Nature on June 25.  The study found that the polysaccharide coating of cancer cells is especially thick and pronounced.

  • The Cornell NEXT Nano Initative


    What If....

    ...we could track and repair individual cells deep inside the body?

    ...we could build an environmental lab inside of a raindrop?

    ...we could nano-engineer batteries to make fossil fuels obsolete?

    ...we could create nanoscale machines as easily as we build electronic circuits?

    NEXT is a mult-year interdisciplinary program at Cornell created to push nanoscale science and microsystems engineering to the next level of design, function and integration.

    Our goal of hiring 10 outstanding nano/micro focused faculty members in the next five years is just the first of the NEXT initiatives at Cornell. Join us in building the future!
