Hemispherical array of ultrasound transducers lifts objects off reflective surfaces. Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a […]

Lightweight aerogel suspended in honeycomb structure. Credit: University of Bath Extremely low-density graphene-based aerogel ‘meringue’ can improve passenger comfort and reduce noise up to 80%. An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath. The graphene […]
