Zinc‐Mediated Photodegradation of Nitrophenols in Aqueous Solution: Devising Environmental Mitigation Strategies With Ultrafast Spectroscopic Insights

open access: yesElectron, EarlyView.
We implement a suite of steady‐state and time‐resolved spectroscopic techniques to elucidate the zinc‐mediated photodegradation of nitrophenols in aqueous solution. From ultrafast electronic spectroscopy of aci‐nitrophenol on femtosecond‐to‐nanosecond timescales to tracking photoproducts with absorption and vibrational signatures (through ground‐state ...

Oxygen isotopic composition of carbon dioxide in the middle atmosphere [PDF]

open access: yes, 2007
The isotopic composition of long-lived trace molecules provides a window into atmospheric transport and chemistry. Carbon dioxide is a particularly powerful tracer, because its abundance remains >100 parts per million by volume (ppmv) in the mesosphere ...

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments

open access: yesHelvetica Chimica Acta, EarlyView.
ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Implantable drug delivery system: Frontiers of medicine‐engineering interdisciplinary

open access: yesInterdisciplinary Medicine, EarlyView.
This review systematically summarizes the driving mechanisms of implantable on‐demand drug delivery systems (IDDS), including endogenous, exogenous, and closed‐loop strategies. It highlights the pivotal roles of flexible electronics and miniaturization in enhancing the tissue conformity and spatial adaptability.

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.
