Dual Frequency Comb Generated on a Single Chip Using a Single Laser

Columbia Engineers are the first to miniaturize dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip; could lead to low-cost, portable sensing and spectroscopy in the field in real-time. In a new paper published today in Science Advances, researchers under the direction of Columbia Engineering Professors Michal Lipson and Alexander

Many More Bacteria Have Electrically Conducting Filaments

Microbiologists led by Derek Lovley at the University of Massachusetts Amherst, who is internationally known for having discovered electrically conducting microfilaments or “nanowires” in the bacterium Geobacter, announce in a new paper this month that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments.

New Soft Electronic Textiles Could Offer Advanced Protection for Soldiers and Emergency Personnel

New technology that harnesses electronic signals in a smart fabric could lead to advanced hazardous-material gear that protects against toxic chemicals, according to research from Dartmouth College. In the research, the chemistry team of Katherine Mirica and Merry Smith describe the creation of new smart fabrics — named SOFT, for Self-Organized Framework on Textiles —
