Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

Efeito do arejamento no processo de compostagem da fracção sólida do chorume de pecuária leiteira Influence of aeration on the process of composting dairy cattle slurry solid fraction

open access: yesRevista de Ciências Agrárias, 2009
A compostagem permite estabilizar a matéria orgânica da fracção sólida do chorume (FSC) da pecuária leiteira intensiva, enquanto a separação entre sólidos e líquidos reduz o volume necessário para o armazenamento destes efluentes.

A Multi‐Scale Geophysical–Geochemical Footprint of Persistent Methane Leakage at a Legacy Petroleum Well

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Fugitive methane leakage from legacy oil and gas wells is assessed using surface flux and soil‐gas measurements, yet these signals are modulated by meteorology and shallow processes, obscuring sustained leakage. Whether persistent leakage leaves a coherent imprint in the shallow subsurface remains unresolved. Here we present a multi‐year field

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...

Ultrafast Control of Coherent Acoustic Lattice Dynamics in the Transition Metal Dichalcogenide Alloy WSSe

open access: yesAdvanced Physics Research, Volume 5, Issue 5, May 2026.
Coherent acoustic phonons are generated and optically controlled in bulk WSSe alloy samples using ultrafast spectroscopy. The alloy exhibits a strong coherent acoustic response, which is not an intermediate state between WS? and WSe?. Instead, a much more complex mechanism is proposed.

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Physics Research, Volume 5, Issue 5, May 2026.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

The end stage of barrier estuary infill: Insights from Jack Smith Lake, Southeastern Australia

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Infill model for the saline coastal lake estuary, Jack Smith Lake. Abstract Jack Smith Lake in southeastern Australia is an infilled saline coastal lake, disconnected from the ocean by a foredune barrier. This study explores the Holocene infill history of this estuary in order to understand the end‐stage evolution of barrier estuarine systems with ...
