A New Electrode Paradigm Enabled by Co‐Axial Electrospinning

open access: yesSmall, EarlyView.
Co‐axial electrospinning creates fuel‐cell electrodes with a division of function: ionomer cores to conduct protons and tailored catalyst‐containing shells for electrochemical reactions. This separation allows a paradigm shift in materials design and functional properties for the core and shell ionomers, targeting chemistries to be tuned independently ...

Precisely Timed On‐Demand Droplet Ejection and Collision in Free Space for Controlled Reaction Initiation

open access: yesSmall, EarlyView.
LiDIA is an on‐demand droplet‐in‐air platform that enables synchronized droplet collision, ultralow‐waste operation, and obstruction‐free sample delivery. By combining precise triggering with reliable free‐space dispensing, it provides a versatile route for rapid mixing and time‐resolved studies, with strong potential for applications in XFEL, cryo‐EM,

Rational Design of LiNi1‐xFexO2 Electrodes for Enhanced Oxygen Evolution Reaction Under Power‐Fluctuating Operations in Alkaline Water Electrolysis

open access: yesSmall Methods, EarlyView.
We develop Fe‐incorporated LiNiO2 for the OER in alkaline media, where Fe enhances Ni3+ oxidation state and optimizes eg orbital filling, significantly improving activity under power fluctuations. ABSTRACT The electrochemical performance of alkaline water electrolyzers is hindered by power fluctuations when integrated with renewable energy sources in ...

Spatial Characterization of the Human Meniscus: Bridging Biomechanics and Biochemistry Using Atomic Force Microscopy Micro‐Indentation and Mass Spectrometry Imaging

open access: yesSmall Methods, EarlyView.
A multimodal imaging approach combines AFM micro‐indentation and MALDI mass spectrometry imaging on the same fresh‐frozen human meniscus section to directly associate microscale mechanics with molecular composition. Collagen‐rich regions exhibit increased stiffness, whereas zones enriched in other extracellular matrix proteins are mechanically less ...
