The lack of fast and strong microactuators is a well-recognized problem in the MEMS community. Electrochemical actuators can develop high pressure but they are notoriously slow. Water electrolysis produced by short voltage pulses of alternating polarity can overcome the problem of slow gas termination due to spontaneous ignition of the reaction between hydrogen and oxygen in nanobubbles. An actuation...
A review of the geochronology, geochemistry and distribution of the 1380Ma Mashak Large Igneous Province (LIP) of the eastern margin of the East European craton indicates a potential link to a major breakup stage of the Mesoproterozoic supercontinent Columbia (Nuna), link to a major stratigraphic boundary (Lower–Middle Riphean), and economic significance for hydrocarbons and metallogeny. Specifically,...
