Multiscale Design of Anion Exchange Membrane‐Based Seawater Electrolysis for Sustainable Hydrogen Production

Advanced Energy Materials, EarlyView.
Direct seawater electrolysis using anion exchange membranes is emerging as a promising route for sustainable hydrogen production. This review summarizes multiscale design strategies from seawater chemistry and OER–ClER selectivity to catalysts, membranes, MEAs, cells, stacks, and system integration, providing a roadmap toward selective, durable, and ...

Engineering Atomically Precise Cu4I4 Nanoclusters With Integrated Adsorption and Hydrogenation Functions for Efficient Photocatalytic Nitrate‐to‐Ammonia Conversion

Angewandte Chemie, EarlyView.
Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.

Synergistic Silylium‐Ion and Palladium Catalysis Enables Migratory Alkene Silylation With Allylsilanes by Formal C–H/C–Si Metathesis

Angewandte Chemie, EarlyView.
Merging silylium‐ion and palladium catalysis provides a mechanistically distinct route to allylsilanes by formal C–H/Si–H metathesis. Using allylsilanes as silicon proelectrophiles, various allylarenes undergo migrative silylation, selectively yielding (E)‐allylsilanes.

Short-Term Fertilizer Nitrogen-to-Phosphorus Stoichiometry and Early Indicators of Soil Carbon Fraction Response Under Contrasting Management Regimes Across Four Cropping Systems in Northern Thailand

Agronomy
Fertilizer nitrogen-to-phosphorus (N/P) stoichiometry diverges between soil test recommendations and conventional farmer practices in tropical Asia; however, its associations with labile soil carbon fractions remain poorly characterized.

Labile and non-labile carbon in Andosol in the North of Þingvallavatn

, 2019
Íslensk eldfjallajörð (e: Andosol) á grónu landi inniheldur alla jafna hátt hlutfall kolefnis en minna er vitað um hversu auðveldlega kolefni losnar frá henni. Markmið rannsóknarinnar sem hér er kynnt er að meta hlut laust bundins og torleysts kolefnis í

Record Dissymmetry in Vibrational Optical Activity: Combining Vibronic Coupling and Aggregation in Cobalt(II) Camphorate Complexes

Angewandte Chemie, EarlyView.
The cobalt(II) bis(trifluoroacetylcamphorate) scaffold exhibits versatile coordination chemistry with solvent‐driven ligand exchange and geometrical rearrangements, associated with unique chiroptical properties. Microcrystalline suspension of [Co(tfc)2(CH3CN)2] revealed the largest VCD dissymmetry factor ever reported (g ≈ 0.2 at 1600 cm−1), arising ...

The non-permanence of optimal soil carbon sequestration [PDF]

Carbon sequestration in agricultural soils is considered as an option of greenhouse gas mitigation in many countries. But, the economic potential is limited by the dynamic process of saturation and the opportunity cost of land use change.
