Lattice Boltzmann Method Analyzing Helium Bubbles Motion in Liquid Helium

IEEE Transactions on Appiled Superconductivity, 2004
To estimate the cooling capability of liquid helium in a superconducting magnet, it is indispensable to analyze the liquid helium flow and the bubble motion. However, it is almost impossible to understand them by means of the experiment or the numerical calculation based on Navier-Stokes equations.

Investigation of Cell Components for Increasing Ethylene Production in Integrated CO2 Electrolysis

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
This study examines how flow field design, gas diffusion electrode (GDE) properties, catalyst loading, GDE compression, and membrane thickness influence ethylene production in a zero‐gap CO2 electrolyzer. The results show that channel size and membrane thickness affect C2+ products.

Resolving Complex Multiscale Structure of Magneto‐ and Electroactive Polymer Composites With an Ionic Liquid

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
Multiscale ionic liquid segregation into nano‐sized domains in the unconfined amorphous polymer phase and into micron‐sized pores enables a coupled magneto‐ and electroactive responses. ABSTRACT A multiscale understanding of the structure of ionogels – nanoparticle‐free polymer composites incorporating ionic liquids – is essential for enhancing their ...

Grain size threshold for enhanced irradiation resistance in nanocrystalline and ultrafine tungsten

Materials Research Letters, 2017
Nanocrystalline metals are considered highly radiation-resistant materials due to their large grain boundary areas. Here, the existence of a grain size threshold for enhanced irradiation resistance in high-temperature helium-irradiated nanocrystalline ...

Tuning Product Distribution in Plasma‐Activated Water by Modifying Reactor Design

Chemistry–Methods, Volume 6, Issue 5, May 2026.
This study systematically compares plasma‐activated water reactor configurations for nitrogen fixation, demonstrating that reactor design, catalyst inegration, and gas flow govern product selectivity. Slurry reactor favor nitrate formation, whereas needle system promote ammonium production.

Nonclassical rotational behavior at the vicinity of the lamda point

, 2006
The rotational property of a quantum liquid at the vicinity of the lambda point is examined. In a liquid helium 4 just above the lambda point, under the strong influence of Bose statistics, the coherent many-body wave function grows to an intermediate ...

Computational Simulation of Shock-Bubble Interaction, using a Front-Tracking/Ghost Fluid Method

Journal of Applied Fluid Mechanics, 2019
A front tracking/ghost fluid method was used to simulate fluid interfaces in a shock–bubble interaction problem. The method captures fluid interfaces, using explicit front-tracking and defines interface conditions, using the ghost-fluid method.
