pH‐dependent electrochemical oxidation of 5‐hydroxymethylfurfural: Reaction mechanism, catalyst design, and reactor design across alkaline to acidic media

Smart Molecules, Volume 4, Issue 1, March 2026.
This review summarizes the progress in pH‐dependent electrochemical oxidation of 5‐hydroxymethylfurfural for value‐added chemical production. It highlights how pH dictates reaction mechanisms and product selectivity, discusses strategies for designing effective electrocatalysts tailored for alkaline, near‐neutral, or acidic electrolytes, and explores ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Large‐Scale Submarine Sediment Waves at Macauley Caldera Volcano: In Situ Evidence of High‐Flux, Syn‐Eruptive Submarine Transport

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)

Heavy Metals in Soils: An Investigation of the Contaminated Floodplains Around the Sinu River, Colombia

GeoHealth, Volume 10, Issue 3, March 2026.
Abstract Heavy metal contamination in rivers mostly originates from anthropogenic sources such as industrial activities, mining, agriculture, and urban runoff. These metals accumulate in river sediments and impact living organisms and the surrounding ecosystem. Historically, some rivers in Colombia have faced issues related to heavy metal contamination,
