Article Abstract

A macrocycle-based approach to the construction of a cationic polymeric network with pillar[5]arene as the node for efficient sequestration of hazardous IO and I is presented. Ultrafast kinetics ( 4 min) were achieved along with excellent adsorption capacities for both IO (456 mg g) and I (370 mg g), good selectivity, and outstanding reusability. This work showcases the merits of pillar[5]arene as nodes in cationic adsorption materials in the removal of anionic iodine species.

Rapidly expanding nascent ecosystems at glacier forefields under climate warming dramatically enhance the terrestrial carbon (C) sink. Microbial C fixation and degradation, closely implicated in nitrogen (N) transformation and plant-soil-microbe interactions, significantly regulate soil C accumulation. However, how shifts in microbial functional potential impact soil C sequestration during vegetation succession remains unclear.

Excessive use of conventional potassium chloride (KCl) fertilizer has led to soil degradation problems such as compaction and salinization. While controlled-release potassium chloride (CRK) fertilizer has the potential to enhance crop productivity and mitigate these problems, its impact on soil quality (SQ) remains unclear. In this study, four potassium (K) fertilization treatments were established: no K application (CK), conventional KCl fertilizer (CRK0), 50 % substitution with CRK (CRK0.

The growing demand for food has led to overuse of land, exacerbating the environmental sustainability of agrifood systems. Insufficient coordination and coupling within agrifood systems (soil-crop-animal-food consumption) reduce material cycle efficiency and limit the system's carbon reduction potential. Given the lack of global research on the impact of system coupling on carbon reduction, the value of regional practice cases is particularly evident.

Sulforaphene (SFE) is a bioactive isothiocyanate, known for its cancer-preventive, anti-inflammatory, and antioxidant properties. However, the application of SFE is severely limited by its poor stability. Hydroxypropyl methylcellulose (HPMC), an amphiphilic carbohydrate polymer, has potentials to enhance the stability of SFE and the loading capacity.

Background: Strongly water-sensitive reservoirs with high clay content face challenges in conventional development due to clay swelling and impeded seepage. CO2 injection shows potential for enhanced oil recovery (EOR) and carbon sequestration; however, the role of clay minerals in regulating CO2-induced asphaltene deposition and sequestration remains unclear.

Methodology: We conducted experiments on clay-oil interactions, nuclear magnetic resonance (NMR), measurements of crude oil properties, and long core water flooding tests to evaluate deposition, reservoir damage, and CO2 sequestration.
