Scientists create “virtual sort nanomachines” that use electron beams to manipulate graphene oxides
Dynamic graphene oxide sorting overview: (a) The system uses an electron beam on silicon nitride to create an electric field pattern that generates a force opposed to the graphene oxide sheet. (b) Start the state with a graphene oxide sheet in the solution. (c) An intermediate step showing a sheet pulled towards the pattern by an electroosmotic flow. (d) The…

Cool Science: Researchers create small biological tools using frozen ethanol
Credit: Eric Stan Imagine drawing something delicate like a living cell without hurting it. Researchers at the University of Missouri made this discovery using a combination of unexpected tools: frozen ethanol, electron beams, and purple-colored microorganisms. By proceeding with a method called ice lithography, the team was able to directly etch the very small, detailed patterns onto fragile biological surfaces.…

Designing a clean energy future: 2d Janus heterobilayers lead
2D Janus Heterobilayers design for efficient water splitting. The unique Janus structure with an internal electric field enhances photocatalytic performance. The blue arrows indicate that optimised conditions for water splitting (e.g. carrier mobility, catalyst surface, etc.) can be achieved by rationally designing 2D heterobilisers like LEGOBRICS. Credit: Nguyen Tuan Hung et al. What if there was an efficient way to…
