Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Cilostazol in patients with heart failure and preserved ejection fraction—The CLIP‐HFpEF trial

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1437-1446, April 2025.
• Cilostazol is an oral PDE‐3 inhibitor that may have advantageous effects in heart failure with preserved ejection fraction (HFpEF). • Cilostazol significantly improved short‐term heart failure‐related health status scores (KCCQ‐12) and NT‐proBNP levels when compared to placebo.

Ti-MCM-41 materials synthesised at room temperature as catalysts for cyclisation of (±)-citronellal” [PDF]

open access: yes, 2009
In the present work we extend the applicability of those Ti-MCM-41 materials, as heterogeneous catalysts, to produce an important intermediate, isopulegol, from the cyclisation of citronellal. The use of this kind of materials appears to be a good option

Synthesis and Characterization of Novel Silylated Sm3+ and Eu3+ Complexes Incorporated Into Mesoporous Silica Nanoparticles

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The strategy of incorporating the Eu(tta‐Si)3(phen) and Sm(tta‐Si)3(phen)2 complexes prevented leaching of the complexes and preserved their intrinsic optical properties. Preliminary studies of silylated Ln3+ complexes and nanoparticles loaded with these complexes demonstrated cytotoxicity against cancer cells, with minimal cytotoxic effect on nontumor
