Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Redox‐Active Bisphosphines Based on a W(II)‐Propargyl Complex Backbone

European Journal of Inorganic Chemistry, EarlyView.
Three bisphosphine ligands based on tungsten(II) propargyl‐type alkyne complexes were synthesized and characterized. The methanolate derivative was used as a metalla‐ligand for the preparation of a binuclear bisphosphine‐κ2‐PdCl2 complex. In both cases, IR spectroelectrochemistry (IR‐SEC) measurements revealed a successive process following oxidation ...

Pt/C‐Catalyzed Deuteration of Polycyclic Aromatic Hydrocarbons with Suppressed Arene Hydrogenation

European Journal of Organic Chemistry, EarlyView.
An additive‐enabled Pt/C protocol promotes hydrogen–deuterium exchange in fused polycyclic aromatic hydrocarbons (PAHs) in D2O/2‐PrOH at 80 °C. Decalin suppresses undesired ring hydrogenation while accelerating on‐ring H–D exchange, furnishing highly deuterated PAHs (PAHs‐dn).

Probing Chiral Recognition on Amylose Tris(3,5‐Dimethylphenylcarbamate) Using Cinnamyl 2‐Aminoanilides: The Subtle Impact of Aliphatic Substituents

ELECTROPHORESIS, EarlyView.
This study investigates how subtle aliphatic substituent differences in racemic cinnamyl 2‐aminoanilides affect chiral recognition on amylose tris(3,5‐dimethylphenylcarbamate). Pronounced enantioselectivity changes arose from minimal structural variations. Mobile phase effects were examined, with 2‐propanol improving resolution.

Production of bioethanol from residual barley and utilization of fermentation co‐products in animal nutrition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The search for sustainable alternatives for bioethanol production has encouraged the valorization of agro‐industrial residues. This study evaluated the use of residual barley as a feedstock for bioethanol production and as a potential ingredient for ruminant feed.

Recent Progress on Graphitic Carbon Nitride–Based Photocatalysts for Hydrogen Peroxide Synthesis

Exploration, EarlyView.
This review summarizes recent progress in using graphitic carbon nitride (g‐C3N4) photocatalysts to produce hydrogen peroxide (H2O2). It highlights how solar energy can cleanly convert water and oxygen into this valuable chemical. We discuss key modification strategies, such as defect engineering, doping, and junction construction, to enhance ...

Sufficient Gas and Solvated Ion Transport Assisted Rapid NH3 Detection at Room Temperature Through Bionic Olfactory Fibres

Exploration, EarlyView.
Bionic olfactory fibres with nanoconfined ionic liquids were developed to mimic human olfactory cilia. Benefiting from sufficient gas transport pathways provided by inter‐fibre interconnected pores and rapid transport of solvated ions in the confined nano spacing, bionic olfactory fibres show excellent sensing performance to NH3 and demonstrate the ...

Characterization of Cantaloupe, Grape, Pumpkin, and Tomato Seed Oils From Xinjiang: Oxidative Stability, Volatile‐Compound Analysis, and Sensory Evaluation

Food Chemistry International, EarlyView.
This study compares oxidative stability, fatty acid profiles, volatile compounds, and sensory attributes of four Xinjiang seed oils. Distinct aldehyde‐driven aroma patterns and compositional differences were revealed, providing a scientific basis for quality evaluation and valorization of underutilized plant seed oils in food applications.
