Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Thickness optimization of Sn–Pb alloys for experimentally measuring mass attenuation coefficients

Nuclear Energy and Technology, 2017
An attempt has been made to experimentally investigate the optimum thickness in order to measure mass attenuation coefficients for some Sn–Pb alloy systems at incident photon energies 122, 511 and 662keV.

Iron oxides impact sulfate-driven anaerobic oxidation of methane in diffusion-dominated marine sediments

Frontiers in Marine Science, 2022
Microbial iron (Fe) reduction by naturally abundant iron minerals has been observed in many anoxic aquatic sediments in the sulfidic and methanic zones, deeper than it is expected based on its energetic yield.

Phonon Engineering in Ultrathin Sn Films

Advanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Magnetic Textiles: A Review of Materials, Fabrication, Properties, and Applications

Advanced Materials Technologies, EarlyView.
Magnetic textiles (M‐textiles) are emerging as a programmable materials platform that merges magnetic matter with hierarchical textile structures. This article consolidates magnetic material classes, textile architectures, and fabrication and magnetization strategies, revealing structure–property–function relationships that govern magneto‐mechanical ...

Single‐Mitochondrion ATP Profiling Directs Discovery of Targetable OXPHOS Dependency in Cancers

Advanced Science, EarlyView.
MitoATP‐nFCM integrates nano‐flow cytometry with fluorogenic probes (ATP/membrane potential) and antibodies to quantify mitochondrial metabolites and protein expression at single‐organelle resolution, exposing oxidative phosphorylation (OXPHOS)‐driven metabolic rewiring in cancers.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Iron isotopes suggest significant aerosol dissolution over the Pacific Ocean [PDF]

Atmospheric Chemistry and Physics
This study presents aerosol iron isotopic compositions (δ56Fe) in the western and central equatorial and tropical Pacific Ocean. Aerosols supply iron (Fe), a critical element for marine primary production, to the open ocean.
