Recent advances in boosting interfacial bubble dynamics with external fields
Droplet, EarlyView.External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

Responsive Materials, EarlyView.We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Weak levitation of 2D delocalized states in a magnetic field.
, 1995 The deviation of the energy position of a delocalized state from the center of Landau level is studied in the framework of the Chalker-Coddington model. It is demonstrated that introducing a weak Landau level mixing results in a shift of the delocalized ...

Energy‐Based Controller Design of Stochastic Magnetic Levitation System [PDF]
Mathematical Problems in Engineering, 2017 This paper investigates the control problem of magnetic levitation system, in which velocity feedback signal is influenced by stochastic disturbance. Firstly, single‐degree‐freedom magnetic levitation is regarded as an energy‐transform action device.

Methods in Ecology and Evolution, EarlyView.Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.
