The atmospheric impacts of monoterpene ozonolysis on global stabilised Criegee intermediate budgets and SO 2 oxidation: experiment, theory and modelling

open access: yes, 2017
. The gas-phase reaction of alkenes with ozone is known to produce stabilised Criegee intermediates (SCIs). These biradical/zwitterionic species have the potential to act as atmospheric oxidants for trace pollutants such as SO2, enhancing the formation ...

Applications of bioactive herbal extracts in dressing materials for skin wound repair: Ingredients, mechanisms and innovations

open access: yesInterdisciplinary Medicine, EarlyView.
Abstract The skin, as the body's largest organ, plays essential roles in protection, immune regulation, and homeostasis. Skin trauma, especially chronic wounds such as diabetic ulcers, poses significant clinical challenges. Traditional treatments, while often effective, can be costly and pose risks.
