Types of quantum turbulence [PDF]

arXiv, 2023
We collect and describe the observed geometrical and dynamical properties of turbulence in quantum fluids, particularly superfluid helium and atomic condensates for which more information about turbulence is available. Considering the spectral features, the temporal decay, and the comparison with relevant turbulent classical flows, we identify three ...

Mussel‐Inspired Molecular Strategies for Fabricating Functional Materials With Underwater Adhesion and Self‐Healing Properties

Advanced Materials, EarlyView.
This review systematically examines the nanomechanical mechanisms of mussel‐inspired molecular interactions, primarily investigated by direct force measurement techniques such as surface forces apparatus and atomic force microscopy. The macroscopic adhesive and self‐healing performances of mussel‐inspired functional materials, including coacervates ...

A systematic dataset generation technique applied to data-driven automotive aerodynamics

APL Machine Learning
A novel strategy for generating datasets has been developed within the context of drag prediction for automotive geometries using neural networks. A primary challenge in this field is constructing a training database of sufficient size and diversity. Our

Experimental Study of Gas Microbubbles on Oil‐Infused Wrinkled Surfaces

Advanced Materials Interfaces, EarlyView.
Microbubbles are observed on both superhydrophobic (SHS) and lubricant‐infused surfaces (LIS) immersed to gassed water. The bubbles on LIS are stabilized by the lubricant cloaking layer, while bubbles on SHS shrink vertically over the same time frame.

Octopus-Inspired Underwater Soft Robotic Gripper with Crawling and Swimming Capabilities

Research
Can a robotic gripper only operate when attached to a robotic arm? The application space of the traditional gripper is limited by the robotic arm. Giving robot grippers the ability to move will expand their range of applications.

Cosmic Ray transport in turbulent magnetic field

, 2013
Cosmic ray (CR) transport and acceleration is determined by the properties of magnetic turbulence. Recent advances in MHD turbulence call for revisions in the paradigm of cosmic ray transport. We use the models of magnetohydrodynamic turbulence that were

3D Wiring Microelectrodes in a PMMA Microfluidic Device by Vacuum Filling Method

Advanced Materials Technologies, EarlyView.
This paper proposes a method for fabricating 3D wiring microelectrodes in arbitrary designs within 3D‐printed microfluidics. By attaching a PDMS lid and using vacuum filling, low‐melting‐point alloy (LMA) is introduced into microchannels. This enables the creation of 50 µm microelectrodes, including complex shapes.

Bifurcation in electrostatic resistive drift wave turbulence

, 2007
The Hasegawa-Wakatani equations, coupling plasma density and electrostatic potential through an approximation to the physics of parallel electron motions, are a simple model that describes resistive drift wave turbulence. We present numerical analyses of
