Microbiological indicators of soil carbon dynamics

open access: yesБюллетень Почвенного института им. В.В. Докучаева
Microorganisms play a key role in the dynamics of soil organic matter (SOM) stocks, redistributing carbon (C) among microbial biomass growth, respiration, polymer synthesis, and intracellular and extracellular enzymatic processes.

Microbial carbon mineralization in tropical lowland and montane forest soils of Peru [PDF]

open access: yes, 2016
Climate change is affecting the amount and complexity of plant inputs to tropical forest soils. This is likely to influence the carbon (C) balance of these ecosystems by altering decomposition processes e.g., "positive priming effects" that accelerate ...

Increasing microbial carbon use efficiency with warming predicts soil heterotrophic respiration globally [PDF]

open access: yesGlobal Change Biology, 2019
AbstractThe degree to which climate warming will stimulate soil organic carbon (SOC) losses via heterotrophic respiration remains uncertain, in part because different or even opposite microbial physiology and temperature relationships have been proposed in SOC models.

From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.
