Experimental Investigation on Carbonation Behavior in Lime‐Stabilized Expansive Soil [PDF]

Advances in Civil Engineering, 2020
The carbonation behavior of lime‐stabilized expansive soil is important for assessing the stabilization efficiency from the perspective of durability. In this study, the accelerated carbonation tests, measurement of pH value distribution, and the free swell ratio tests were conducted to investigate the evolutions of carbonation depth, carbonation ...

Microscale carbon distribution around pores and particulate organic matter varies with soil moisture regime

Nature Communications, 2022
Carbon sequestration in soils has rarely been observed at microscopic scales. Here the authors reveal the impact of soil moisture regimes in shaping carbon stabilization and mineralization patterns tied to the pore network.

Stability of soil aggregates and their ability of carbon sequestration [PDF]

Soil and Water Research, 2014
One of the most important binding agents for forming stable aggregates is a soil organic matter (SOM), which can be retained in various size fractions of aggregates. If aggregates are water-resistant, they retain more carbon. Therefore, the aim of this study was to evaluate the stability of aggregates and their ability of carbon sequestration in ...

Soil Organic Carbon Stabilization: Mapping Carbon Speciation from Intact Microaggregates

Environmental Science & Technology, 2018
The clearing of land for agricultural production depletes soil organic carbon (OC) reservoirs, yet despite their importance, the mechanisms by which C is stabilized in soils remain unclear. Using synchrotron-based infrared microspectroscopy, we have for the first time obtained in situ, laterally resolved data regarding the speciation of C within ...

The stability of soil organic carbon across topographies in a tropical rainforest

PeerJ, 2021
Mechanisms of soil organic carbon (SOC) stability are still unclear in forest ecosystems. In order to unveil the influences of topography on the SOC stability, a 60ha dynamic plot of a tropical montane rainforest was selected in Jianfengling, in Hainan Island, China and soil was sampled from 60 quadrats.

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

Advanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Biomarkers reveal vulnerability of plant and microbial carbon to sea-level rise in estuarine wetlands

Communications Earth & Environment
Coastal wetlands are critical blue carbon sinks, yet contributions and stabilization mechanisms of key soil organic carbon components—plant-derived carbon, microbial necromass carbon, and glomalin-related soil protein—remain poorly quantified.
