MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

Advanced Functional Materials, EarlyView.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Numerical analysis of noise characteristics of a contra-rotating axial fan

IOP Conference Series: Earth and Environmental Science, 2012
Numerical analysis of the flow-field in a contra-rotating fan has been performed by using the CFD method. The LES technique is applied to simulate the 3D unsteady whole flow-field of the fan. Several monitoring faces are specified in the flow-field between the two impellers.
