Listen for Failure

Authors: George Rajna

In a pilot study, researchers from North Carolina State University and Haverford College have used naturally arising acoustic vibrations—or sound waves—to monitor the state of granular materials. [35] Scientists at the University of Alberta have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. [34] Chemist Dr. Lars Borchardt and his team at TU Dresden recently achieved a huge breakthrough in the synthesis of nanographenes. [33] Using graphene as a light-sensitive material for light detectors offers significant improvements with respect to materials being used nowadays. [32] The precision of measuring nanoscopic structures could be substantially improved, thanks to research involving the University of Warwick and QuantIC researchers at the University of Glasgow and Heriot Watt University into optical sensing. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29] Magnetic materials that form helical structures—coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule—occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors—sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields.
