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.

Adaptive self-excited vibrations suppression during milling
Journal of Physics: Conference Series, 2019 The problem of the occurrence and rapid suppression of unstable self-excited vibrations arising in the process of milling is considered. It is assumed that tool (cutter) is connected with machine overarm by an elastic suspension, which is used for force sensation. The tool moves evenly along the work surface with a given pressure on it. Pressing of the

Advanced Functional Materials, EarlyView.This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Raman scattering in current carrying molecular junctions. A preliminary account
, 2008 This is a preliminary acount of a theory for Raman scattering by current-carrying molecular junctions. The approach combines a non-equilibrium Green's function (NEGF) description of the non-equilibrium junction with a generalized scattering theory ...
