Weirdly flowing water finally has an explanation: ' quantum friction '

How quantum friction explains water’s strange flows in carbon nanotubes, and the latest from the Nature Briefing.In this episode:00:53 A theory for water’s baffling behaviour in carbon nanotubesAt large scales, water flows faster through a wider pipe than a narrower one. However, in tiny carbon nanotubes flow-rate is flipped, with water moving faster through the narrowest channels. This week, researchers have come up with a new explanation for this phenomenon: quantum friction. If validated, it could allow material designers to fine-tune flows through tiny channels, which could be useful in processes such as water purification.Research Article: Kavokine et al.06:43 Research HighlightsCreating soap bubbles that last 200,000 times longer, and hippos’ habit of aggressively spraying dung when they hear a stranger.Research Highlight: No bursting for these record-breaking bubblesResearch Highlight: Hippos know strangers’ voices — and make a filthy reply09:08 Briefing ChatWe discuss some highlights from the Nature Briefing.
