Heterointerface Engineering of FeOOH@Ni3N Electrocatalysts for Industrially Compatible Alkaline Water Electrolysis

open access: yesSmall, EarlyView.
A hierarchically structured FeOOH@Ni3N electrocatalyst supported on Ni foam enables high‐rate alkaline water electrolysis with industrial‐level stability. Operando spectroscopy reveals that the Fe–Ni heterointerface stabilizes high‐valent Ni4+ = O/Fe4+ = O species and promotes a hydroxyl nucleophilic attack (HNA) mechanism, wherein OH− attack on ...

Single‐Particle Characterization Reveals Heterogeneous Extracellular Vesicle Fusion with Liposomes

open access: yesSmall Methods, EarlyView.
This study used five orthogonal single‐particle techniques to compare how common mechanical methods fuse extracellular vesicles with liposomes. By quantifying fused‐particle yield, purity, and vesicle integrity, we found that freeze‐thaw and sonication generated the highest fusion but that all methods introduced membrane perturbation or damage.

Big data in veterinary medicines regulation: A data landscape analysis to support regulatory activities

open access: yesVeterinary Record, EarlyView.
Abstract Background This study describes the development of a data landscape analysis protocol that identifies and characterises animal health data sources to support key regulatory activities throughout the life cycle of veterinary medicines. Methods The protocol included: development of criteria to identify data sources; selection of variables to ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

open access: yesWildlife Society Bulletin, EarlyView.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

A dedicated beamline for wide‐energy‐range X‐ray spectroscopy at SSRF: combining soft and hard X‐ray capabilities

open access: yesJournal of Synchrotron Radiation, EarlyView.
A wide‐range beamline (130–10000 eV) combining both soft X‐ray and hard X‐ray photons has been constructed at SSRF for in situ X‐ray photoemission spectroscopy investigations of the solid–gas interface, and for hard X‐ray photoemission spectroscopy studies with layer‐by‐layer resolution.The advancement of renewable energy critically depends on the ...

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Dietary resilience of coral reef fishes to habitat degradation

open access: yesJournal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Generation cycles in experimental populations of a multivoltine insect

open access: yesJournal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.
