Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

open access: yesAdvanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

A Note on the Unsteady Cavity Flow in a Tunnel [PDF]

open access: yes, 1974
The unsteady internal cavitating flow such as the one observed in a pump or a turbine is studied for a simple two-dimensional model of a base-cavitating wedge in an infinite tunnel and it is shown how the cavitation compliance can be calculated using the

Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

open access: yesAdvanced Functional Materials, EarlyView.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

Development and experimental validation of a transient 2D numeric model for radiant walls [PDF]

open access: yes, 2018
An experimental set-up consisting of a house like cubicle exposed to outdoor weather was used to validate a numerical model of a radiant wall. The 2D transient finite volume model used as inputs the indoor temperature, outdoor temperature, global solar ...

A Non‐Reciprocal Architected Porous Medium

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

NUMERICAL INVESTIGATION OF LIQUID CARRYOVER IN T-JUNCTION WITH DIFFERENT DIAMETER RATIOS

open access: yesPlatform, a Journal of Engineering, 2017
T-junction is commonly used in distributing two-phase flow in a piping system, especially in oil and gas industries. In offshore Malaysia, T-junction is installed at the production header as a compact separator to tap produced gas from reservoir as fuel ...

Seepage stability of dispersive soil-structure interface

open access: yesYantu gongcheng xuebao
The dispersive soil has the characteristics of dispersing and losing when encountering water. The buildings located in the dispersive soil often suffer from seepage deformation at the interface under the coupling effects of soils-water-buildings, which ...

Diels‐Alder Click Chemistry as a Dynamic‐Covalent Crosslinking Method in Spheroid‐Encapsulating Hydrogels for Cartilage Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This research shows the development of hydrogels with Diels‐Alder click chemistry for engineering cartilage‐like tissue. The hydrogels support cartilage spheroids which could be cultured for at least 28 days. Furthermore, the spheroids showed a tendency to fuse together into a more consistent construct, and produced important components needed for ...
