Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Polymer‐Derived Nickel‐Iron Silicide‐Based Bimetallic Catalysts: Synthesis, Characterization, and Enhanced Catalytic Properties Toward the Oxygen Evolution Reaction

open access: yesChemElectroChem, Volume 13, Issue 6, 17 March 2026.
The growing demand for green energy highlights the need for efficient hydrogen production through water splitting. Designing bimetallic electrocatalysts is crucial for this goal. Transition metal silicides are promising due to their abundance and high electrical conductivity.

Na4Ba9MnN3: A New Subnitridometalate with Trigonal Planar Anions [MnIIIN3]6−

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
The new subvalent nitridomanganate(III) Na4Ba9MnN3 contains structural elements known from ionic subnitridometalates as well as from intermetallic phases. In similarity to Ba3MnN3, isolated trigonal planar nitridomanganate(III) anions (MnN3)6−, coordinated by barium atoms represent the ionic region, while mixed barium‐sodium icosahedra known from ...

On New Alkaline Sulfatometallates: Cs6[(WO2)2O(SO4)4], K8[(MoO2)2(SO4)6], K7.9Sr0.1[(WO2)2(SO4)6] and Na4[MoO2(SO4)3]

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
Two new alkaline sulfatometallates show promising optical absorption, emission and even non‐linear optical properties together with an astonishingly high thermal stability. The new sulfatotungstate Cs6[(WO2)2O(SO4)4] exhibits a hitherto unknown anion with an unusual W–O–W angle of 180° and edge‐sharing WO6 and SO4 polyhedra.
