Photosensitizer‐Mesoporous Silica Nanoparticles Combination for Enhanced Photodynamic Therapy†

Photochemistry and Photobiology, Volume 99, Issue 3, Page 882-900, May/June 2023., 2023
The photodynamic therapy efficiency against cancer can be enhanced by the use of mesoporous silica nanoparticles (MSNs), considered ideal nanocarriers for photosensitizers (PSs) due to their high surface areas, simple and cost‐effective synthesis, easy surface functionalization, biocompatibility, and optically transparent to light absorption.

Waste‐free oxidation of alcohols at the surface of catalytic electrodes: What is required for industrial uptake?

Electrochemical Science Advances, Volume 2, Issue 5, October 2022., 2022
Abstract The electrocatalytic oxidation of alcohols at the surface of stable catalytic electrodes functionalized with aminoxyl radicals results in a waste‐free process affording highly valued carbonyl or carboxylic compounds using an electric current only.

Elliptical Birefringent Rib‐Channel Chirowaveguides for Quasicircularly Polarized Light Applications in Integrated Photonics

Advanced Photonics Research, Volume 3, Issue 7, July 2022., 2022
Circular and elliptical polarizations in photonic integrated circuits are difficult to handle due to polarization beating from transverse electric/magnetic polarization decomposition. Engineering a chiral material with a dedicated cross‐sectional shape allows realization of chirowaveguides supporting elliptically polarized guided modes.
