Cavity‐Enhanced Eye‐Readable Detection of 0.1% H2 via Active Modulation of Charge‐Transfer Plasmons

open access: yesAdvanced Science, EarlyView.
A cavity‐structured nanoparticle sensor is developed for highly sensitive, eye‐readable hydrogen detection. Its excellent colorimetric response arises from a hydrogen‐induced charge‐transfer mechanism: reduction of the dielectric oxide shell in H2 triggers a transition from the plasmonic gap mode to the charge‐transfer plasmon mode.

Lattice Chloride Shielding and Reconstructed Phosphate Armor for Stable Seawater Electrolysis

open access: yesAdvanced Science, EarlyView.
A dual‐protection strategy integrating lattice Cl shielding with dynamically reconstructed phosphate armor enables selective OH adsorption and suppresses chloride‐induced corrosion during alkaline seawater electrolysis, delivering durable operation at industrial‐level current densities.

Phylogeography and the evolution of correlated traits under multiple origins of aposematism in the poison frog family [PDF]

open access: yes, 2009
textLiving organisms are under selection not only for one, but also for several inheritable characters at the same time. Well-sampled and well-supported phylogenies are necessary for the studies of character evolution and their history.

Co‐Ligand‐Induced Electronic Modulation Controls Substrate Adsorption and Selectivity in Biomass Electrooxidation

open access: yesAdvanced Science, EarlyView.
A molecular design strategy is reported that introduces distinct anionic co‐ligands into Cu‐based catalysts to modulate the electronic density of the metal center and, consequently, its interaction with both OHads and HMF. The work establishes co‐ligand engineering as an effective strategy for precise interfacial adsorption control in electrocatalysis,

Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

open access: yesAdvanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.
