Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

open access: yesAdvanced Materials Technologies, EarlyView.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

Modeling of Hydrogen Atom Adsorption and Diffusion in Ti3Sb Intermetallic Crystal with A15 Cubic Structure

open access: yesSurfaces
For the first time, the adsorption of hydrogen on the (110) surface of the A15 Ti3Sb compound with a cubic structure (Cr3Si type; space group Pm3¯n) for the accumulation of hydrogen H was calculated using the density functional theory method (DFT SGGA ...

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Energy‐Resolved Femtosecond Dynamics of Plasmon‐Induced Hole Injection at Au/GaN Heterointerfaces

open access: yesAdvanced Science, EarlyView.
We reveal the spectral signature of ultrafast nonthermal hot‐hole transfer at plasmonic heterointerfaces, which reshapes hot‐carrier relaxation dynamics and significantly enhances hydrogen evolution, providing a mechanistic basis for optimizing hot‐carrier utilization in photocatalysis.

A Hydrogen‐Releasing Nanozyme Engineers a Mitochondrial ROS Amplifier for Self‐Sustaining Catalytic Immunotherapy

open access: yesAdvanced Science, EarlyView.
We developed a RhPd‐H nanozyme that integrates enhanced POD‐mimetic catalytic activity with thermally triggered H2 release. H2 shields and reprograms mitochondria to continuously leak endogenous ·O2−. This dual‐path ROS spatially and temporally disrupts redox homeostasis, inducing persistent oxidative stress for tumor suppression and antitumor immunity,

Characterizing solute hydrogen and hydrides in pure and alloyed titanium at the atomic scale [PDF]

open access: yes, 2018
Ti and its alloys have a high affinity for hydrogen and are typical hydride formers. Ti-hydride are brittle phases which probably cause premature failure of Ti-alloys.

In Situ Formation of an In–Zn Interface Layer Enables Aqueous Zinc‐Ions Batteries with High Capacity Retention

open access: yesAdvanced Science, EarlyView.
This work demonstrates an indium zinc oxide (IZO)‐modified separator applied to aqueous zinc ion batteries (AZIBs), which in situ generates an In–Zn interface layer to stabilize the separator/anode region during the cycling process. The In–Zn interface layer provides richer nucleation sites for Zn2+ and suppresses side reactions.

Advances in highly hydrided palladium

open access: yesFrontiers in Materials
Palladium is a prototypical hydride-forming metal, which can accommodate a large volume of hydrogen through the formation of either interstitial or complex hydrides.
