Identification of plasma and urinary metabolites and catabolites derived from orange juice (poly)phenols: analysis by high-performance liquid chromatography–high-resolution mass spectrometry [PDF]

open access: yes, 2016
Orange juice is a rich source of (poly)phenols, in particular, the flavanones hesperetin-7-O-rutinoside and naringenin-7-O-rutinoside. Following the acute consumption of 500 mL of orange juice containing 398 μmol of (poly)phenols by 12 volunteers, 0–24 h

Electrochemical oxidation of benzoic acid and its aromatic intermediates on boron doped diamond electrodes

open access: yesCurrent Research in Green and Sustainable Chemistry, 2021
Electrochemical oxidation using Boron-doped diamond (BDD) electrodes is a promising purification technique to remove organic pollutants, such as benzoic acid, from wastewaters. In this study the oxidation of benzoic acid has been investigated on rotating

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

A Light‐Driven Closed‐Loop Chemical Recycling System for Polypinacols

open access: yesAdvanced Materials, EarlyView.
This study presents a novel strategy for the photochemical closed‐loop recycling of hydroxyl‐rich polymers. Simple bis‐aldehyde precursors are employed to synthesize polypinacols via UV light irradiation. Subsequent depolymerization is achieved under visible light using a cerium‐based photocatalyst, enabling monomer recovery through selective cleavage ...

Rationalizing the Unexpected Inefficiencies of 3D Porphyrin‐MOFs as Singlet Oxygen Photosensitizers Against Botrytis cinerea

open access: yesAdvanced Materials Interfaces, EarlyView.
Unexpected results show that the singlet‐oxygen based antifungal activity of porphyrin‐based Metal‐Organic Frameworks is far below expectations while the standalone ligand is more efficient. We attribute these behaviours to inefficient exciton migration and gas diffusion leading to low singlet oxgyen concentrations at and beyond the MOF‐gas interface ...
