Ultrasound‐Actuated Gene Editing in Human Kidney Organoids

Advanced Science, EarlyView.
Peptide‐stabilized nanoemulsions enable spatially controlled, ultrasound‐triggered delivery of gene‐editing proteins deep within human kidney organoid tissues. Focused acoustic pulses drive droplet vaporization, propelling cargo into target renal cells while preserving native tissue microarchitecture. This non‐viral platform improves both the depth and

Engineering Neuronal Network Connectivity Through Precise and Scalable Electrical Modulation

Advanced Science, EarlyView.
This study presents a scalable all‐electrical method for precise neuronal‐circuit reconfiguration based on high‐density microelectrode arrays. By employing biologically inspired plasticity rules, targeted connectivity changes were successfully induced and quantified across diverse neuronal preparations.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications

Advanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Turbulent pulsations in the axisymmetrical submerged jet

Journal of Physics: Conference Series, 2020
Abstract Today, the turbulent characteristics of laminar jets remain almost unexplored, although all real flows have a pulsating component, which in technological processes can have a significant effect on the processes of mixing, heat and mass transfer.

Experimental and numerical study on the flapping motion of submerged turbulent plane jet

, 2013
A submerged, vertical turbulent plane water jet impinging onto a free surface will be self-excited into a flapping oscillation when the jet velocity, leaving the jet orifice, exceeds a critical value.
