Two-port equivalent circuit model for UHVDC converter valves

CSEE Journal of Power and Energy Systems, 2019
UHVDC converter valves during operation may experience overvoltage, which come from the AC or DC systems to which they are connected. Therefore, building an equivalent circuit model (ECM) for the converter valve to analyze the interlayer transient ...

3D Printed Meter‐Scale Soft Origami Robots Capable of Load‐Bearing Actuation Via Crease Stiffness Modulation

Advanced Science, EarlyView.
Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.

Monolayer MoS2 With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance

Advanced Science, EarlyView.
This study demonstrates that controlling precursor dosages in atomic layer deposition (ALD) serves to regulate ultrathin oxide quality, which in turn determines sulfurization behavior and MoS2 monolayer continuity. The resulting continuous, low‐defect monolayers enable improved piezoelectric performance and support a flexible slippage sensor, linking ...

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

Advanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...
