Fluid dynamics
Cilia are characterized by slender, threadlike projections, which are used by biological organisms to control fluid flows at the microscale. Attempts to mimic these structures and engineer cilia-like systems to have broad applications have proved problematic. In this week’s issue, Wei Wang and colleagues present electronically controlled artificial cilia that can be used to create flow patterns in near-surface liquids. The researchers use surface-mounted platinum strips, each about 50 micrometres long, 5 micrometres wide and 10 nanometres thick, and capped on one side with titanium. Applying an oscillating potential with an amplitude of around 1 volt to the cilia drives ions on to and off of the exposed platinum surface. These ions create asymmetric forces that generate a beating pattern that can be used to pump surface liquids in various flow geometries. The cover shows an artist’s impression of the artificial cilia in action.

National Geographic Traveller – June 2022
The June 2022 issue of National Geographic Traveller (UK).
The June issue of National Geographic Traveller (UK) is out now. The cover story this month focuses on Scandinavia — Denmark, Norway and Sweden — where nature throws out the rulebook. Shaped by the elements and ruled by the seasons, this is a region not only bound by cultural ties, but by a love for epic outdoor adventures. From oyster safaris on Denmark’s dramatic shoreline and wilderness camping in Norwegian national parks to learning about Sámi culture in Swedish Lapland, these are the ultimate Scandinavian experiences.

Nature Magazine, May 19, 2022 – At industrial scales, chemical reactions are typically driven by applying continuous heat to the reactants. In this week’s issue, Liangbing Hu and his colleagues show that pulsed heating and quenching can enhance synthetic performance while also saving energy.
The researchers use a programmable electric current to switch between high and low temperatures very quickly — typically 0.02 seconds on, 1.08 seconds off. Rapidly quenching the reaction gives high selectivity, maintains catalyst stability and reduces energy usage. The cover image illustrates the heater in action for the pyrolysis of methane — the model reaction the team tested. Methane molecules travel through the pores of the high-temperature heater and are selectively converted into useful products.
