A nanoscale observation to explain the discrepancy of electron exchange capacities between biochar containing comparable surface redox-active moieties

Biochar, 2022
Highlights The microscopic distribution of RAMs on biochar was achieved by combining C-AFM and a mediated electrochemical method. The uneven distribution of RAMs enabled biochar to possess outstanding EEC by enhancing accessibility.

Electron transfer mediated activation of periodate by contaminants to generate 1O2 by charge-confined single-atom catalyst

Nature Communications
The electron transfer process (ETP) is able to avoid the redox cycling of catalysts by capturing electrons from contaminants directly. However, the ETP usually leads to the formation of oligomers and the reduction of oxidants to anions.

A qPCR method to quantify bioavailable phosphorus using indigenous aquatic species

Environmental Sciences Europe, 2018
Background Bioavailable phosphorus (BAP) represents the sum of phosphorus that is readily available for algae growth and is useful to indicate the severity of eutrophication in aquatic environments. Results Here, a quantitative real-time PCR (qPCR)-based
