Previous observations showed that there are two major types of mesoscale plasma sheet bubbles (plasma with relatively lower total entropy than ambient plasma): the type‐1 has density lower and temperature higher than ambient plasma, and the type‐2 has the opposite differences. We first show, from statistical analysis of observations, that both the type‐1 and type‐2 bubbles can be possibly generated locally by magnetic reconnection in the magnetotail. We then conduct simulations based on the Rice Convection Model to show that the density and temperature characteristics of a bubble can affect the bubble's evolution and associated magnetic field and flow perturbations through magnetic drift and precipitation. For both types, the bubble extends azimuthally as it moves inward, and

Abstract B zis enhanced near the bubble's earthward front. The flow perturbations within the bubble consist of two interchange flow vortices with a fast earthward‐flow channel near the center and return flows on the two sides. The low entropy of a bubble is contributed by the reduction in the higher energy ions in the type‐2 bubble but in the lower energy ions in the type‐1 bubble. Duskward magnetic drift of the bubble's depleted high‐energy ions allows the type‐2 bubble and theB zenhancement to expand azimuthally wider toward dusk than does the type‐1 bubble. The electrons within the type‐2 bubble produce weaker ionospheric conductance, in particular on the dawnside of the bubble because these electrons drift toward dawn, which results in stronger flows within the dawnside flow vortex, as compared to the type‐1 bubble. -
We present an experimental study of bubble coalescence at an air–water interface and characterize the evolution of both the underwater neck and the surface bridge. We explore a wide range of Bond number, $Bo$ , which compares gravity and capillary forces and is a dimensionless measure of the free surface's effect on bubble geometry. The nearly spherical $Bo\ll 1$ bubbles exhibit the same inertial–capillary growth of the classic underwater dynamics, with limited upper surface displacement. For $Bo>1$ , the bubbles are non-spherical – residing predominantly above the free surface – and, while an inertial–capillary scaling for the underwater neck growth is still observed, the controlling length scale is defined by the curvature of the bubbles near their contact region. With it, an inertial–capillary scaling collapses the neck contours across all Bond numbers to a universal shape. Finally, we characterize the upper surface with a simple oscillatory model which balances capillary forces and the inertia of liquid trapped at the centre of the liquid-film surface.more » « less

Abstract The most explosive basaltic scoria cone eruption yet documented (>20 km high plumes) occurred at Sunset Crater (Arizona) ca. 1085 AD by undetermined eruptive mechanisms. We present melt inclusion analysis, including bubble contents by Raman spectroscopy, yielding high total CO2(approaching 6000 ppm) and S (~2000 ppm) with moderate H2O (~1.25 wt%). Two groups of melt inclusions are evident, classified by bubble vol%. Modeling of post-entrapment modification indicates that the group with larger bubbles formed as a result of heterogeneous entrapment of melt and exsolved CO2and provides evidence for an exsolved CO2phase at magma storage depths of ~15 km. We argue that this exsolved CO2phase played a critical role in driving this explosive eruption, possibly analogous to H2O exsolution driving silicic caldera-forming eruptions. Because of their distinct gas compositions relative to silicic magmas (high S and CO2), even modest volume explosive basaltic eruptions could impact the atmosphere.

Abstract The generation of renewable electricity is variable, leading to periodic oversupply. Excess power can be converted to H2via water electrolysis, but the conversion cost is currently too high. One way to decrease the cost of electrolysis is to increase the maximum productivity of electrolyzers. This study investigates how nano‐ and microstructured porous electrodes can improve the productivity of H2generation in a zero‐gap, flow‐through alkaline water electrolyzer. Three nickel electrodes—foam, microfiber felt, and nanowire felt—are studied to examine the tradeoff between surface area and pore structure on the performance of alkaline electrolyzers. Although the nanowire felt with the highest surface area initially provides the highest performance, this performance quickly decreases as gas bubbles are trapped within the electrode. The open structure of the foam facilitates bubble removal, but its small surface area limits its maximum performance. The microfiber felt exhibits the best performance because it balances high surface area with the ability to remove bubbles. The microfiber felt maintains a maximum current density of 25 000 mA cm−2over 100 h without degradation, which corresponds to a hydrogen production rate 12.5‐ and 50‐times greater than conventional proton‐exchange membrane and alkaline electrolyzers, respectively.

null (Ed.)Remotely activated drug release strategy with controllable dosage is the key factor of various targeting drug delivery methods as minimal invasive treatment. This article describes mass transport in liquid in microscale with a controllability of releasing amount, which is wirelessly excited by an external acoustic excitation. A liquid droplet (releasing agent, or drug in application) is trapped in the middle of a one-end open microtube which has a ratchet-structure on its inner wall. The droplet is trapped in the tube and neighbored by two gaseous air bubbles on both sides. In the presence of acoustic wave, the air bubbles oscillate and resonate. The air bubble near the tube opening segregates the liquid droplet into smaller ones and transport them on the ratchet-surface wall of the microtube. This mass transport occurs in both directions at similar rates: from the surrounding fluid to the trapped droplet and vice versa. As a result, the overall mass of droplet remains similar. Meanwhile, the other bubble positioned back in the tube sealing side enhances mixing between incoming mass from the surrounding and existing mass in the droplet. This mass transport is significant only when the inner wall of the tube has rachets. The exchanging mass between the surrounding and droplet is monotonically proportional to the excitation period, showing high controllability of mass transport. This mass transport phenomenon possibly provides a new mechanism of in vivo, on-demand, dose controllable drug delivery.more » « less
