Evidence of Critical Balance in Kinetic Alfven Wave Turbulence Simulations

, 2011
A numerical simulation of kinetic plasma turbulence is performed to assess the applicability of critical balance to kinetic, dissipation scale turbulence. The analysis is performed in the frequency domain to obviate complications inherent in performing a

Magnetic Flux Guides by Material Extrusion

Advanced Science, EarlyView.
Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide

Toward Energy‐Efficient Alkaline Water Electrolysis: Advances in Mass Transport Optimization and Electrolyzer Design

Advanced Energy Materials, EarlyView.
Component‐level engineering in alkaline water electrolysis (AWE) is systematically analyzed, highlighting strategies in porous electrodes, bubble management, membranes, and flow fields to overcome mass‐transport bottlenecks. By linking microstructural design to multi‐scale ionic and gas transport, this Review establishes design principles that connect ...

Non-existence of normal tokamak equilibria with negative central current [PDF]

, 2003
Recent tokamak experiments employing off-axis, non-inductive current drive have found that a large central current hole can be produced. The current density is measured to be approximately zero in this region, though in principle there was sufficient ...

A Compact, High‐Performance, and Deformation‐Resilient Trielectrode Electrostatic Soft Pump for Soft Robotics

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Existing soft pumps often require tradeoffs between performance and compatibility with soft robotic systems. The proposed trielectrode electrostatic soft pump addresses these limitations through an innovative driving mechanism. Its design, which includes a trielectrode configuration and the use of compliant materials, improves operational efficiency ...

Astrophysical turbulence modeling

, 2011
The role of turbulence in various astrophysical settings is reviewed. Among the differences to laboratory and atmospheric turbulence we highlight the ubiquitous presence of magnetic fields that are generally produced and maintained by dynamo action.
