Atomic size differences guide nanoscale structural control of metal aerogels
Nov 27, 2024 (Nanowerk Spotlight) Chemical reactions power everything from industrial manufacturing to clean energy production, but their efficiency depends critically on catalysts - materials that speed up reactions without being consumed. The key to a catalyst's performance lies in its microscopic architecture, which determines how easily molecules can reach...
Engineers knit a ‘blanket’ of sophisticated radio-frequency antennas
Nov 27, 2024 (Nanowerk News) Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable garment -- a sweater or a blanket that is ultralight, portable, easy to fold up and stow away. Not having to use heavy, bulky satellite...
Paving the way for graphene biosensor based diagnostics
Nov 27, 2024 (Nanowerk News) Two-dimensional materials such as graphene are not only ultrathin, but also extremely sensitive. Researchers have therefore been trying for years to develop highly sensitive biosensors that utilise this property. Graphene-based field-effect transistors, for example, could register the tiniest changes in the electronic properties caused by...
