Enhanced Photocatalytic Degradation of the Imidazolinone Herbicide Imazapyr upon UV/Vis Irradiation in the Presence of CaᵪMnOᵧ-TiO₂ Hetero-Nanostructures: Degradation Pathways and Reaction Intermediates
(MDPI, 2020-05-08)
[Abstract] The determination of reaction pathways and identification of products of pollutants degradation is central to photocatalytic environmental remediation. This work focuses on the photocatalytic degradation of the ...
An Efficient Green Photo-Fenton System for the Degradation of Organic Pollutants. Kinetics of Propranolol Removal From Different Water Matrices
(Elsevier, 2022-01-06)
[Abstract] We report on the degradation of aqueous propranolol (PRO) in a heterogeneous system with natural iron oxide (N.I.O.) and oxalic acid (OAA) under near UV–Vis irradiation. Photolysis experiments showed ca. 65% ...
Mechanical Stability Is Key for Large-Scale Implementation of Photocatalytic Surface-Attached Film Technologies in Water Treatment
(Frontiers, 2021-10-18)
[Abstract] Replacement of classical tertiary water treatment by chemical-free sunlight-driven photocatalytic units has been often proposed. Photocatalysts are required to be cost-effective, inert, chemically stable, reusable, ...
Removal of Emerging Pollutants by a 3-Step System: Hybrid Digester, Vertical Flow Constructed Wetland and Photodegradation Post-treatments
(Elsevier, 2022-06-22)
[Abstract] The removal of emerging pollutants from municipal wastewater was studied for the first time using a three-step pilot-scale system: 1) hybrid digester (HD) as first step, 2) subsurface vertical flow constructed ...
Effect of Ionizing Radiation on Human Myeloperoxidase: Reaction With Hydrated Electrons
(Elsevier, 2021-11-27)
[Abstract] Myeloperoxidase (MPO) is a myeloid-lineage restricted enzyme largely expressed in the azurophilic granules of neutrophils. It catalyses the formation of reactive oxygen species, mainly hypochlorous acid, ...
Improved Photocatalyzed Degradation of Phenol, as a Model Pollutant, over Metal-Impregnated Nanosized TiO₂
(MDPI, 2020-05-22)
[Abstract] Photocatalyzed degradation of phenol in aqueous solution over surface impregnated TiO₂ (M = Cu, Cr, V) under UV-Vis (366 nm) and UV (254 nm) irradiation is described. Nanosized photocatalyts were prepared from ...
Face-Fusion of Icosahedral Boron Hydride Increases Affinity to γ‐Cyclodextrin: closo,closo‐[B₂₁H₁₈]⁻ as an Anion with Very Low Free Energy of Dehydration
(Wiley, 2020-03-12)
[Abstract] The supramolecular recognition of closo,closo‐[B₂₁H₁₈]⁻ by cyclodextrins (CDs) has been studied in aqueous solution by isothermal titration calorimetry and nuclear magnetic resonance spectroscopy. These solution ...
On the Dissociation Pathways of Copper Complexes Relevant as Pet Imaging Agents
(Elsevier, 2022)
[Abstract] Several bifunctional chelators have been synthesized in the last years for the development of new 64Cu-based PET agents for in vivo imaging. When designing a metal-based PET probe, it is important to achieve ...
Removal of Paracetamol in the Presence of Iron(III) Complexes of Glutamic and Lactic Acid in Aqueous Solution Under NUV Irradiation
(Elsevier, 2021-01-05)
[Abstract] Low concentrations of drugs and their metabolites occurring on the aquatic environment are of significant concern due to their potential effects. This work reports on the removal from aqueous solution, of ...
Differential Features of Short-Lived Intermediates: Structure, Properties and Reactivity
(Elsevier, 2020-10-22)
[Abstract] Some general features of short-lived intermediates that can be useful when facing mechanistic studies or other projects involving these species are briefly revised, with special attention to properties of neutral ...
