Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives

EcoEnergy, EarlyView.
Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

Microclimate mediates the strength and direction of avian biotic interactions

Ecography, EarlyView.
Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Community‐level egg and larval trait interactions with the Amazon River plume determine its role as a dispersal barrier

Ecography, EarlyView.
The Amazon River plume (ARP) functions as a dynamic and porous biogeographic barrier whose permeability to larval dispersal depends on the interplay between species' biological traits and oceanographic processes. Using biophysical modeling combined with a dual analytical framework, namely a multivariate regression tree (MRT) and a generalized additive ...

Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Anion Exchange Pathways in Half‐Heusler‐Type Holmium Hydride Oxide HoHO

European Journal of Inorganic Chemistry, EarlyView.
The oxidation of half‐Heusler‐type holmium hydride oxide HoHO in air is tracked by in situ neutron powder diffraction, revealing Ho2H0.50O2.75 as the holmium analogue of the Y2H0.50O2.75 intermediate in YHO. Despite nearly identical ionic radii and closely related intermediate structures, the holmium system shows a narrower stability range and faster ...

Sustainable Iron Catalysis for Chemodivergent Oxidation of Lignin‐Based Vanillyl Alcohol: Selective Access to Vanillin and Vanillic Acid

European Journal of Organic Chemistry, EarlyView.
Green reaction media enable chemodivergent oxidation of vanillyl alcohol, selectively affording vanillin or its fully oxidized counterpart, vanillic acid. The use of an earth‐abundant, inexpensive, and nontoxic iron catalyst for the transformation of lignin‐derived alcohol to fine chemicals underscores the sustainability of the process. A low E‐factor (

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Conformal and Multi‐Domain Radio Frequency Energy Harvesting System Based on Graphene for Internet of Things Applications

Interdisciplinary Materials, EarlyView.
This study details a multi‐domain graphene assembled film (GAF) based radio frequency (RF) energy harvesting system (GEHS) for Internet of Things (IoT) applications. The GEHS integrates a flexible dual‐band, dual‐polarization, dual‐beam antenna array based on GAF materials with a high‐efficiency rectifier.
