By capturing the laser-induced structural changes happening in polycrystalline gold thin films over time, scientists determined that melting does not occur uniformly—a finding that could have implications to laser micromachining of precision parts
Recent research from materials science and engineering professors, Simon Billinge and Katayun Billinge, was featured in a recent Columbia Engineering Magazine web exclusive: Engineering the Future of Cultural Preservation.
Scientists have developed a platform for assembling nanosized material components of very different types—inorganic or organic—into desired 3-D structures. Though self-assembly has successfully been used to organize nanomaterials of several kinds, the process has been extremely system-specific, generating different structures based on the intrinsic properties of the materials. As reported in Nature Materials, their new DNA-programmable nanofabrication platform can be applied to organize a variety of 3-D materials in the same prescribed ways at the nanoscale (billionths of a meter), where unique optical, chemical, and other properties emerge.
Prof. Katayun Barmak was a featured speaker at the Women in Engineering Day on April 19, hosted by Columbia Engineering’s undergraduate chapter of the Society of Women Engineers (SWE). The event, hosted by Dean Mary Boyce, featured 5 faculty members who spoke about their current research and also offered advice and insights from their career paths.
