Bifunctional Paramagnetic and Luminescent Clays Obtained by Incorporation of Gd³⁺ and Eu³⁺ Ions in the Saponite Framework
(American Chemical Society, 2021-07-08)
[Abstract] A novel bifunctional saponite clay incorporating gadolinium (Gd³⁺) and europium (Eu³⁺) in the inorganic framework was prepared by one-pot hydrothermal synthesis. The material exhibited interesting luminescent ...
Rigidified Derivative of the Non-macrocyclic Ligand H₄OCTAPA for Stable Lanthanide(III) Complexation
(American Chemical Society, 2022-03-11)
[Abstract] The stability constants of lanthanide complexes with the potentially octadentate ligand CHXOCTAPA4–, which contains a rigid 1,2-diaminocyclohexane scaffold functionalized with two acetate and two picolinate ...
Defining the Conditions for the Development of the Emerging Class of Feᴵᴵᴵ-Based MRI Contrast Agents
(Royal Society of Chemistry, 2021-07-26)
[Abstract] Fe(III) complexes are attracting growing interest in chemists developing diagnostic probes for Magnetic Resonance Imaging because they leverage on an endogenous metal and show superior stability. However, in ...
Viologen–cucurbituril host/guest chemistry – redox control of dimerization versus inclusion
(Royal Society of Chemistry, 2021-09-02)
[Abstract] Two calix[4]arene systems, C234+ and C244+ – where 2 corresponds to the number of viologen units and 3–4 corresponds to the number of carbon atoms connecting the viologen units to the macrocyclic core – have ...
Introducing Hyaluronic Acid into Supramolecular Polymers and Hydrogels
(American Chemical Society, 2021-10-18)
[Abstract] The use of supramolecular polymers to construct functional biomaterials is gaining more attention due to the tunable dynamic behavior and fibrous structures of supramolecular polymers, which resemble those found ...
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% ...
Understanding the Effect of the Electron Spin Relaxation on the Relaxivities of Mn(II) Complexes with Triazacyclononane Derivatives
(American Chemical Society, 2021-10-07)
[Abstract] Investigating the relaxation of water ¹H nuclei induced by paramagnetic Mn(II) complexes is important to understand the mechanisms that control the efficiency of contrast agents used in diagnostic magnetic ...
A Snapshot on the Occurrence and Risk Assessment of Organic Pollutants in an Urban River
(MDPI, 2022-12-22)
[Abstract] A snapshot screening was carried out in an urban river at the end of a dry period in the water and sediments to assess the presence and environmental risk for the following CECs: paracetamol, ibuprofen, diclofenac, ...
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, ...
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 ...
