Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Balloon Aortic Valvuloplasty

Journal of Interventional Cardiology, 1998
Since the description by Lababidi in 1983 of balloon aortic valvuloplasty, it has been used extensively by several groups of workers for relief of valvar aortic stenosis of moderate to severe degree. The indications for the procedure are peak‐to‐peak gradients ≥ 50 mmHg with symptoms or ECG changes or a gradient of ≥ 70 mmHg irrespective of the ...

A Liquid Metal Balloon for the Exfoliation of an Ultrathin and Uniform Gallium Oxide Layer

Molecules
We report the exfoliation of ultrathin gallium oxide (Ga2O3) films from liquid metal balloons, formed by injecting air into droplets of eutectic gallium–indium alloy (eGaIn).
