Doubling down on metasurfaces

Apr 01, 2025 Researcher have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. (Nanowerk News) Almost a decade ago, Harvard engineers unveiled the world’s first visible-spectrum metasurfaces – ultra-thin, flat devices patterned with nanoscale structures that could precisely control...

New tool reveals the true threat of nanoplastics

Apr 01, 2025 An international team of scientists is developing an ultra precise, efficient and flexible technique for counting and analyzing nano-scale scourge. (Nanowerk News) While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one...
