Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

open access: yesAdvanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Postweaning horizontal movements and diving behavior of a recovering grey seal (Halichoerus grypus atlantica) population in the western North Atlantic

open access: yesAnimal Biotelemetry
Background Conserving marine predators is tantamount to maintaining functional marine ecosystems. Though intensively studied in other regions, little is known about at-sea movements and diving behaviors of a recovering population of grey seals ...

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

open access: yesAdvanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water

open access: yesAdvanced Materials, EarlyView.
An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...

Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

open access: yesAdvanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Fine-scale determinants of female grey seal (Halichoerus grypus) pupping site and habitat preferences at North Rona, Scotland. [PDF]

open access: yes, 2013
The grey seal (Halichoerus grypus) is widespread in the Northern Hemisphere and throughout its range hauls out to breed terrestrially on a variety of substrates.

Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

open access: yesAdvanced Materials, EarlyView.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...

Undulating Seal Whiskers Evolved Optimal Wavelength‐to‐Diameter Ratio for Efficient Reduction in Vortex‐Induced Vibrations

open access: yesAdvanced Science
Seals are well‐known for their remarkable hydrodynamic trail‐following capabilities made possible by undulating flow‐sensing whiskers that enable the seals to detect fish swimming as far as 180 m away.
