942“…In this communication, we report an ultrasound-assisted method, utilising human red blood cell (RBC) or erythrocyte membranes, to produce acoustically active “bubbles”, intended for vasculature imaging. The resulting RBC membrane bubbles have an average size of 1.5 μm with a generally spherical morphology, altered internal aqueous compartment contents, and small gas-containing protrusions or “pockets” in between the membrane bilayer. …”

943“…[Image: see text] The number of bubbles likely to form in a glass of beer is the result of the fine interplay between dissolved CO(2), tiny particles or glass imperfections acting as bubble nucleation sites, and ascending bubble dynamics. …”

944“…This study determines the effect of the configuration of the magnetic field on the movement of gas bubbles that evolve from platinum electrodes. Oxygen and hydrogen bubbles respectively evolve from the surface of the anode and cathode and behave differently in the presence of a magnetic field due to their paramagnetic and diamagnetic characteristics. …”

945por Potente, Stefan, Ramsthaler, Frank, Kettner, Mattias, Ikeda, Tomoya, Schmidt, Peter“…The visual recognition of known persons using “bubbled” images was successfully tested. CONCLUSION: The “bubbling” procedure for visual identification enhancement is quick and straightforward and may be attempted before escalating to more involved identification methods and procedures.…”

946por Park, Ryeol, Choi, Minsu, Park, Eun Hyun, Shon, Won-Jun, Kim, Ho-Young, Kim, Wonjung“…The dynamic actions of cavitation bubbles in ultrasonic fields can clean surfaces. Gas and vapor cavitation bubbles exhibit different dynamic behaviors in ultrasonic fields, yet little attention has been given to the distinctive cleaning effects of gas and vapor bubbles. …”

949“…Based on potential flow and perturbation theory, a theoretical model is derived to describe the pulsation, translation, and deformation of twin bubbles in an ultrasound field. The amplitudes of radial oscillation, translation, and deformation of twin bubbles are found to depend on initial translation velocities. …”

950“…An understanding of the dynamics of growth-driven coalescence is important in diverse fields across natural science and engineering. Motivated by the bubble coalescence in magma during volcanic eruptions, we study both experimentally and theoretically the coalescence of two growing bubbles in a Hele–Shaw cell. …”
