A Transient Model for Fuel Cell Cathode-Water Propagation Behavior inside a Cathode after a Step Potential

Energies, 2010
Most of the voltage losses of proton exchange membrane fuel cells (PEMFC) are due to the sluggish kinetics of oxygen reduction on the cathode and the low oxygen diffusion rate inside the flooded cathode.

Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

Advanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Quantifying Psychosocial Impacts From Coastal Hazards for Cost-Benefit Analysis in Eastern Quebec, Canada

Frontiers in Climate, 2021
The assessment of psychosocial impacts related to coastal hazards (erosion, submersion) has so far been mainly qualitative. As cost-benefit analysis is gaining popularity among communities to assess adaptation options in the face of increasing coastal ...

Interlayer Design for Halide Electrolytes in All‐Solid‐State Lithium Metal Batteries

Advanced Materials, EarlyView.
Halide solid electrolytes, an emerging family of materials, encounter anodic stability challenges that limit their application. By synthesizing Li3YbCl6 and Li3LuCl6 and incorporating a Li6PI3 interlayer, this study achieves lithium‐stable halide electrolytes with reduced interface resistance and enhanced critical current density.

Efficient Low‐temperature Ammonia Cracking Enabled by Strained Heterostructure Interfaces on Ru‐free Catalyst

Advanced Materials, EarlyView.
Leveraging the strong metal‐support interaction effect, heterostructured interfaces in a Co‐based catalyst are designed to enable low‐temperature ammonia (NH3) decomposition. The induced tensile lattice strain within the core‐shell structure modulates d‐band center of Co, enhancing NH3 adsorption and facilitating N─H bond dissociation. Furthermore, the
