Even with defects, graphene is strongest material in the world

June 2, 2013 – 4:00 pm
  • Even with defects, graphene is strongest material in the world - In a new study, published in Science, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form.(10.1126/science.1235126)

    Columbia engineers manipulate a buckyball by inserting a single water molecule

    May 7, 2013 – 3:03 pm
  • Columbia engineers manipulate a buckyball by inserting a single water molecule - Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and drive motion of the "big" nonpolar ball through the encapsulated "small" polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. This method could lead to new applications including effective ways to control drug delivery and to assemble C60-based functional 3D structures at the nanoscale level.(10.1103/Physics.6.43)

    Unraveling intricate interactions, 1 molecule at a time

    August 13, 2012 – 1:01 pm

    Unraveling intricate interactions, 1 molecule at a time - In a key step towards the design of better organic electronic devices, a Columbia Engineering team has succeeded in performing the first quantitative characterization of van der Waals interactions at metal/organic interfaces at the single-molecule level. In a study published Aug. 12 in Nature Materials, the researchers reveal the existence of two distinct binding regimes in gold-molecule-gold single-molecule junctions, using molecules containing nitrogen atoms at their extremities that are attracted to gold surfaces.(10.1073/pnas.1113256108)
