Fluorescence detection of hydroxyl radicals in water produced by atmospheric pulsed discharges [PDF]

open access: yes, 2015
It has been proven that hydroxyl (OH) radicals can be generated by streamer discharges across water surfaces under ambient atmospheric conditions. Hydroxyl radicals have the highest oxidation capability amongst all oxygen-based reactive species, thus OH ...

Conjugation of nitrated acetaminophen to Der p1 amplifies peripheral blood monocyte response to Der p1.

open access: yesPLoS ONE, 2017
BACKGROUND:An association of acetaminophen use and asthma was observed in the International Study of Asthma and Allergies in Childhood study. However there are no clear mechanisms to explain an association between acetaminophen use and immunologic ...

XH-stretching overtone transitions calculated using explicitly correlated coupled cluster methods [PDF]

open access: yes, 2010
We have calculated XH-stretching (where X=O, C, F, Cl) fundamental and overtone transitions for three diatomics and a few small molecules using a local mode model.

Reaction intermediates and molecular mechanism of Peroxynitrite activation by NO synthases [PDF]

open access: yes, 2016
The activation of peroxynitrite (PN) by hemoproteins, which leads to its detoxification or on the contrary to the enhancement of its cytotoxic activity, is a reaction of physiological importance that is still poorly understood. It has been known for some

Kinetics of Bacterial Inactivation by Peroxynitric Acid in the Presence of Organic Contaminants

open access: yesApplied and Environmental Microbiology, 2021
A good disinfectant for the human body should have various properties, such as strong bactericidal activity, harmlessness to living tissues, and resistance against biological fluids (or other organic contaminants). Peroxynitric acid (PNA) showed a bactericidal effect that was several tens up to several hundred times higher per unit of molarity than ...

Peroxynitrite Mediated Oxidations: Spin Trap Studies; Nitration and Hydroxylation of Phenol Result From Different Intermediates; CO(2) Catalyzes the Decomposition of Peroxynitrite. [PDF]

open access: yes, 1997
In the first project the spin trap DMPO was used to probe for the production of hydroxyl radicals from peroxynitrite. Peroxynitrite reacts with DMPO to give $\sp\cdot$DMPO-OH, suggesting that $\sp\cdot$DMPO-OH results from a reaction between DMPO and ...

Inferring ozone production in an urban atmosphere using measurements of peroxynitric acid [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Abstract. Observations of peroxynitric acid (HO2NO2) obtained simultaneously with those of NO and NO2 provide a sensitive measure of the ozone photochemical production rate. We illustrate this technique for constraining the ozone production rate with observations obtained from the NCAR C-130 aircraft platform during the Megacity Initiative: Local and ...

Evaluation of the Ochratoxin A Reduction and Physicochemical Properties of Green Coffee Beans Following Atmospheric Nonthermal Plasma and Plasma‐Activated Water Treatments

open access: yeseFood, Volume 6, Issue 2, April 2025.
This study demonstrated that a combined treatment using plasma‐activated water (PAW) and nonthermal plasma (NTP) achieved the highest ochratoxin A reduction in green coffee beans, with up to 51.80% removal, compared to individual treatments. Notably, this combined approach preserved bean quality, showing minimal impact on color, phenolic content, and ...

Degradation of 1,4-dioxane by reactive species generated during breakpoint chlorination: Proposed mechanisms and implications for water treatment and reuse

open access: yesJournal of Hazardous Materials Letters, 2022
Breakpoint chlorination, an important chemical process relevant to chlorine-based advanced oxidation processes for potable reuse and to traditional water treatment, was investigated for its oxidative capacity, generation of reactive species, and ...
