COVID-19 virus survives on surfaces within thin film
To find out how the COVID-19 virus survives on surfaces, researchers are exploring the drying times of thin liquid films that persist after most respiratory droplets evaporate. While the drying time of typical respiratory droplets is on the order of seconds, the survival time of the COVID-19 virus was on the order of hours. In Physics of Fluids, the researchers describe how a nanometers-thick liquid film clings to the surface, allowing the virus to survive. (2020-11-24)

From lab to industry? Ideally ordered porous titania films, made at scale
Researchers from Tokyo Metropolitan University have realized high-throughput production of thin, ordered through-hole membranes of titanium dioxide. Titania layers were grown using anodization on mask-etched titanium before being crystallized. Applying a second anodization, they converted part of the layer back to an amorphous state. The amorphous portion was then selectively dissolved to free the film while leaving the template intact. This paves the way for industrial production of ordered titania membranes for photonics.
