Impacts of Biogeochemical Redox Processes

Biogeochemical Redox Processes and their Impact on Contaminant Dynamics SUMMARY: Reduction and oxidation reactions are the drivers behind many biological processes. Energy is both stored and transferred through these reactions. This article talks about the various redox reactions that can occur, both biotically and abiotically, and how that affects both biogeochemical cycles and contaminants. The… Continue reading Impacts of Biogeochemical Redox Processes

Silver Dressing and Bacteria

Wound management in an era of increasing bacterial antibiotic resistance: A role for topical silver treatment(NOT OPEN ACCESS) SUMMARY: One way of fighting antibiotic resistant bacteria is to prevent them from growing in the first place. This article looks at three different types of silver dressing, intended to do just that: silver nitrate, silver sulfadiazine,… Continue reading Silver Dressing and Bacteria
