Bayesian Estimation of the Hydroxyl Radical Diffusion Coefficient at Low Temperature and High Pressure from Atomistic Molecular Dynamics [PDF]
, 2021 The hydroxyl radical is the primary reactive oxygen species produced by the radiolysis of water, and is a significant source of radiation damage to living organisms. Mobility of the hydroxyl radical at low temperatures and/or high pressures is hence a potentially important factor in determining the challenges facing psychrophilic and/or barophilic ...

Glutathione--hydroxyl radical interaction: a theoretical study on radical recognition process. [PDF]
PLoS ONE, 2013 Non-reactive, comparative (2 × 1.2 μs) molecular dynamics simulations were carried out to characterize the interactions between glutathione (GSH, host molecule) and hydroxyl radical (OH(•), guest molecule).

Study on Hydroxyl Radical Scavenging Ability of Fermented Kelp Waste
Chemical Engineering Transactions, 2016 In order to develop a new pathway to scavenge hydroxyl radical and to utilize kelp waste, edible-medicinal fungi was fermented in medium mainly composed of kelp waste, and the products from fermentation were investigated with hydroxyl radical scavenging ...

Behavior of Hydroxyl Radicals on Water Ice at Low Temperatures [PDF]
, 2021 Because chemical reactions on/in cosmic ice dust grains covered by amorphous solid water (ASW) play important roles in generating a variety of molecules, many experimental and theoretical studies have focused on the chemical processes occurring on the ASW surface. In laboratory experiments, conventional spectroscopic and mass-spectrometric detection of

Direct Observation and Quantitative Measurement of OH Radical Desorption During the Ultraviolet Photolysis of Liquid Nonanoic Acid [PDF]
, 2022 Ultraviolet (UV) photolysis of fatty acid surfactants which cover the surfaces of atmospheric liquid aerosols and are found in the oceans such as nonanoic acid (NA) has recently been suggested as a source of hydroxyl (OH) radicals in the troposphere. We used laser-induced fluorescence to directly observe OH radicals desorbed from the surface of neat ...

Functionalization of graphene sponge electrodes with two-dimensional materials for tailored electrocatalytic activity towards specific contaminants of emerging concern [PDF]
Chemical Engineering Journal, 2022, 2022 Low-cost graphene sponge electrodes were functionalized with two-dimensional (2D) materials, i.e., borophene and hexagonal boron nitride (hBN), using a one-step, hydrothermal self-assembly method. Borophene and hBN-modified graphene sponge anode and N-doped graphene sponge cathode were employed for electrochemical degradation of model persistent ...

Incorporation of essential oils into biopolymer films based on pumpkin oil cake in order to improve their antioxidant activity [PDF]
Journal on Processing and Energy in Agriculture, 2019 Active films based on pumpkin oil cake, with 1 % and 2 % of winter savory and basil essential oil, were synthesized in the paper, and the antioxidant activity of the films obtained was subsequently examined.
