Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.

Atmospheric Corrosion Protection of LPBF Manufactured AlSi10Mg by Combining SiOx‐CVD and PDMS Grafting

open access: yesMaterials and Corrosion, EarlyView.
Hybrid SiOₓ‐CVD/PDMS ultrathin films mitigate atmospheric corrosion of additively manufactured AlSi10Mg. Electrochemical analyses show reduced corrosion currents, increased charge‐transfer resistance, and suppressed pitting due to diminished cathodic activity and limited oxygen and ion transport under NaCl exposure.

Super‐capacitive carbon materials with large micropores and rich mesopores synthesized using N, S co‐doped carbon dots as self‐templates

open access: yesResponsive Materials, EarlyView.
Nitrogen‐sulfur co‐doped carbon dots are employed as self‐templates to fabricate hierarchical porous carbon material with a concentrated micropore size distribution of 1.1–1.6 nm and a high mesopore volume ratio up to 47.2%, which shows good capacity and excellent responsive ability as electrodes in electrochemical supercapacitors.

Laser‐Assisted In Situ Fabrication of rGO/Bi2O3 Nanocomposites for Heavy Metal Sensing

open access: yesSmall, EarlyView.
Rapid CO2 laser irradiation drives the in situ formation of Bi2O3 nanoplatelets within reduced graphene oxide, yielding flexible, reproducible electrodes with excellent stripping voltammetric performance toward trace heavy metals. ABSTRACT In this work, we introduce a laser‐assisted approach to synthesize reduced graphene oxide/bismuth oxide (III) (rGO/

Linking Pulse‐Duration‐Controlled Laser Nanostructuring to Oxygen Evolution Kinetics in Fe‐enriched NiOx Electrodes

open access: yesSmall, EarlyView.
Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...
