Unlocking efficient light-energy conversion with stable coordination nanosheets

Leave a Comment / Blog, Technology / By

(Tokyo University of Science) Two-dimensional “nanosheets” made of bonds between metal atoms and organic molecules are attractive candidates for photoelectric conversion, but get corroded easily. In a new study, scientists from Japan and Taiwan present a new nanosheet design using iron and benzene hexathiol that exhibits record stability to air exposure for 60 days, signaling …

The virus trap

Leave a Comment / Blog, News / By

(Technical University of Munich (TUM)) To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested …

Thumb-sized device quickly ‘sniffs out’ bad breath

Leave a Comment / Blog, Technology / By

(American Chemical Society) No one wants bad breath — not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious dental issues are occurring. Now, researchers reporting in ACS Nano have constructed …
