Degradation of bisphenol A by ozonation: rate constants, influence of inorganic anions, and by-products [PDF]

open access: yesMaejo International Journal of Science and Technology, 2012
The second-order rate constants for the reaction between bisphenol A (BPA) and ozonewere evaluated over the pH range of 2-12. The rate constants showed minimum values (×104 M-1s-1)under acidic condition (pH < 4) and were of maximum values (×109 M-1s-1 ...

Extremely Long Electron Lifetime in Spontaneously Passivated Polycrystalline Perovskite Layers via Illumination‐Assisted Trap Filling

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

open access: yesAdvanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for
