Performance evaluation and microbial community succession analysis of co-composting treatment of refinery waste activated sludge.

Refinery waste activated sludge (RWAS) is riched in organic matter with energy recovery value, while unique petroleum components in RWAS may pose challenges to the recycling process. Aerobic composting technology is an effective means of organic solid waste resource treatment, which can convert organic solid waste into fertilizer for agriculture. This study explores the effect of petroleum components on the performance of RWAS composting by co-composting it with chicken manure.

Survival strategies and assembly mechanisms of microbial communities in petroleum-contaminated soils.

This study analyzed petroleum-contaminated soils from south and north locations in China to explore the structure, diversity, functional genes and assembly processes of microbial communities' . Compared with soils from south locations, soils from northern regions exhibited elevated pH, total nitrogen (TN), and total petroleum hydrocarbon (TPH) levels. Among these, TN and TPH were the most influential on the microbial community.

Electronic-Control Friction Behavior of Porous Metal-Organic Framework@Ag Nanocrystals as Self-Repairing Lubricant Additive.

The low conductivity and poor antifriction performance of lubricants are the main causes of wear failure in mechanical equipment under electronic-control friction. Metal-organic framework (MOF) nanocomposites can be used to fabricate a new kind of lubricant additive. Herein, porous Cu-BTC@Ag MOF nanocrystals were successfully synthesized via an in situ generation method.

Roles of Oxygen Vacancies in the Bulk and Surface of CeO for Toluene Catalytic Combustion.

Catalytic combustion technology is one of the effective methods to remove VOCs such as toluene from industrial emissions. The decomposition of an aromatic ring via catalyst oxygen vacancies is usually the rate-determining step of toluene oxidation into CO. Series of CeO probe models were synthesized with different ratios of surface-to-bulk oxygen vacancies.
