Photochemical pathways of 8-oxo-2′-deoxyguanosine under photodegradation

AIP Advances, 2022
The common product of an oxidatively damaged DNA, 8-oxo-2′-deoxyguanosine (8-oxo-dG), is known for photorepairing cyclobutane pyrimidine dimers. This study is to uncover the dynamics of 8-oxo-dG under photodegradation, which are poorly understood.

Mathematical Modeling and Mechanism of VUV Photodegradation of H2S in the Absence of O2

International Journal of Photoenergy, 2018
The existence of H2S has limited the biogas energy promotion. The traditional photodegradation of H2S is usually conducted in the presence of O2, yet this is unsuitable for biogas desulfurization which should be avoided.

Photodegradation of Sulfadiazine in Aqueous Solution and the Affecting Factors

Journal of Chemistry, 2016
Knowledge about photochemical behavior of sulfonamides under UV light is limited. In this study, photodegradation of sulfadiazine in water by ultraviolet (UV) light was studied using a 300 W, 365 nm UV lamp.

Enhancement of Methylene Blue Photodegradation Rate Using Laser Synthesized Ag-Doped ZnO Nanoparticles

Nanomaterials, 2022
In this work, Ag-doped ZnO nanoparticles are obtained via pulsed laser ablation of the Ag-coated ZnO target in water. The ratio of Ag dopant in ZnO nanoparticles strongly depends on the thickness of the Ag layer at the ZnO target.

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Investigation of the Effects of Dioctyl Sulfosuccinate on the Photodegradation of Benzo[a]Pyrene in Aqueous Solutions under Various Wavelength Regimes

Molecules, 2023
Due to the relatively high concentrations of polycyclic aromatic hydrocarbons (PAHs) in oil samples, oil spills in aquatic ecosystems release significant amounts of PAHs.
