Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction

Advanced Functional Materials, EarlyView.
This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

Bifurcation and stability analysis of aircraft turning manoeuvres [PDF]

, 2008
During ground manoeuvres a loss of lateral stability due to the saturation of the main landing gear tyres can cause the aircraft to enter a skid or a spin. The lateral stability is governed not only by aspects of the gear design, such as its geometry and

Engineering of Crystallinity to Amplify Chiroptical Activity of TiO2 Nanohelices for Enhancing Dissymmetric Circularly Polarized Photocatalysis

Advanced Functional Materials, EarlyView.
Enhancing crystallinity through thermal annealing leads to amplifying the chiroptical activity of TiO2 nanohelices (NHs) fabricated by glancing angle deposition, ascribed to the suppression of charge trapping. The enhanced chiroptical activity can be converted into pronounced dissymmetric photocatalytic kinetics of circularly polarized photocatalysis ...
