Apr 10, 2021 (Nanowerk News) Excessive CO2 emissions are a major cause of climate change, and hence reducing the CO2 levels in the Earth's atmosphere is key to limit adverse environmental effects. Rather than just capture and store CO2, it would be desirable to use it as carbon feedstock for...

Better metric for thermoelectric nanomaterials means better design strategies
Apr 10, 2021 (Nanowerk News) Researchers from Tokyo Metropolitan University have shown that a quantity known as "thermoelectric conductivity" is an effective measure for the dimensionality of newly developed thermoelectric nanomaterials. Studying films of semiconducting single-walled carbon nanotubes and atomically thin sheets of molybdenum sulfide and graphene, they found clear...
Nanotechnology Now – Press Release: Kirigami-style fabrication may enable new 3D nanostructures
Home > Press > Kirigami-style fabrication may enable new 3D nanostructuresStrategically placed cuts to structural films can create 3D nanostructures when force is applied to the films, similar to how kirigami cuts made to paper can create pop-up structures.

Clocking the fastest-spinning brown dwarfs (w/video)
Apr 08, 2021 (Nanowerk News) Astronomers at Western University have discovered the most rapidly rotating brown dwarfs known. They found three brown dwarfs that each complete a full rotation roughly once every hour. That rate is so extreme that if these "failed stars" rotated any faster, they could come close...
Nanotechnology Now – Press Release: A general approach to high-efficiency perovskite solar cells
Home > Press > A general approach to high-efficiency perovskite solar cellsResearchers from the Institute for Applied Physics (IAP) and the Center for Advancing Electronics Dresden (cfaed) at TU Dresden developed a general methodology for the reproducible fabrication of high efficiency perovskite solar cells. Their study has been published in...
Decades of hunting detects footprint of cosmic ray superaccelerators in our galaxy
Mar 31, 2021 (Nanowerk News) An enormous telescope complex in Tibet has captured the first evidence of ultrahigh-energy gamma rays spread across the Milky Way. The findings offer proof that undetected starry accelerators churn out cosmic rays, which have floated around our galaxy for millions of years. The research is...
