Fate and stabilization of labile carbon in a sandy boreal forest soil – A question of nitrogen availability?

Applied Soil Ecology, 2023
Labile carbon (C) fractions, such as sugars, may persist in soil due to their incorporation into microbial biomass and are ultimately stabilized as microbial necromass as part of stable soil organic matter (SOM). However, the underlying factors and mechanisms are currently highly debated.

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

Advanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Comparing carbon sequestration efficiency in chemically separated soil organic carbon fractions under long-term fertilization in three major Chinese croplands

Journal of Integrative Agriculture
The combined application of organic manure and chemical fertilizers is an effective way to enhance soil organic carbon (SOC) sequestration through its influences on organic carbon (OC) input and the stability of SOC fractions.

Effect of Six Different Feedstocks on Biochar’s Properties and Expected Stability

Agronomy, 2022
Biochar (BC) is often proposed as a tool for climate change mitigation, due to the expected long lifetime in the environment. However, BC’s stability can vary depending on feedstock type and the presence of labile carbon fractions.

Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

Advanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

STABILITY OF ORGANIC MATER OF HAPLIC CHERNOZEM AND HAPLIC LUVISOL OF DIFFERENT ECOSYSTEMS [PDF]

Journal of Central European Agriculture, 2013
In this study, the changes in soil organic matter (SOM) and the possibilities of their monitoring in a shorter period of time by means of carbon parameters were followed. The experiment includes four ecosystems (forest, meadow, urban, and agro-ecosystem)

Soil labile organic carbon and carbon-cycle enzyme activities under different thinning intensities in Chinese fir plantations

, 2016
Thinning is a silvicultural tool that is used to facilitate the growth of timber plantations worldwide. Plantations are important CO2 sinks, but the mechanism by which thinning affects the quantity and stability of soil organic carbon (SOC) is poorly ...

Bio-renewable precursor fibers from lignin/polylactide blends for conversion to carbon fibers [PDF]

, 2014
This article is under embargo until March 2016 per publisher policy.Lignin, a highly aromatic biopolymer extracted as a coproduct of wood pulping, was investigated as a suitable precursor for carbon fibers. Lignin was chemically modified and blended with

Light‐Programmed Localized Supersaturation Enables Ambient Aqueous Synthesis of Highly Crystalline Metal–Organic Frameworks

Advanced Materials, EarlyView.
In the proposed model, a photoinduced nanoreactor uses Cu2O self‐photooxidation to generate localized supersaturation. A metastable supersaturation state first forms a shell, creating a spatially confined environment that restricts reactant exchange; continued Cu release then drives the local environment toward a labile regime that favors predominantly

Long-term effects of organic and inorganic fertilizers on the carbon management index in terrace soils

Discover Soil
Carbon management index (CMI) provides a sensitive indicator of soil quality changes under different management practices. This study assessed the long-term (32-year) impacts of organic and inorganic fertilizers on CMI and soil carbon (C) fractions in ...
