Soil Degradation Evidence Following a Wildfire in Arequipa’s Andean Region, Peru
Spanish Journal of Soil ScienceFire is a natural ecological force, but its effects vary significantly depending on the ecosystem. While fire-adapted ecosystems, such as Mediterranean woodlands, recover quickly, non-fire adapted regions like the Peruvian Andes are highly vulnerable to ...

Aggregate‐occluded black carbon in soil
European Journal of Soil Science, 2006 Summary The great stability of black carbon (BC) in soils may not be solely attributable to its refractory structure but also to poor accessibility when physically enveloped by soil particles. Our aim was to elucidate the intensity of physical entrapment of BC within soil aggregates.

Advanced Healthcare Materials, EarlyView.This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Soil Aggregation by Microorganisms Following Soil Fumigation
Soil Science Society of America Journal, 1958 Abstract The influence of autoclaving and of fumigation with eight chemical formulations upon microbial numbers in straw‐amended Peorian loess and the extent to which these treatments affect the degree of aggregation brought about by subsequently introduced inocula were determined. A mixed soil flora,
