Metal–Metal Bonding in Tri‐Actinide Clusters: A DFT Study of [An3Cl6]z (z=1–6) and [An3Cl6Cp3]z (z=−2–+3; An=Ac, Th, Pa, U, Np, Pu)

ChemPhysChem, Volume 26, Issue 4, February 16, 2025.
The 3‐centre metal–metal bonding in the tri‐actinide clusters [An₃Cl₆]z (z=1–6) and [An₃Cl₆Cp₃]z (z=−2–+3; An=Ac–Pu) is explored using computational chemistry methods. The studied clusters have 2, 1 or 0 electrons in the 3‐centre MOs and their electronic structures and geometries are discussed.

Models for Single‐Site Heterogeneous Catalysts on Carbon: MoO2 Epoxidation Catalyst Anchored to a Fullerene

ChemCatChem, Volume 16, Issue 23, December 6, 2024.
We report the synthesis and characterization of well‐defined single‐site molybdenum‐dioxo catalysts grafted on hydroxylated fullerenes as models for catalysts having molybdenum‐dioxo units on less regular carbons. Characterization via a battery of physical techniques and DFT computation confirm the structures.

Ambipolar field-effect transistor behavior of Gd@C82 metallofullerene peapods [PDF]

, 2002
Transport properties of C_60 fullerene peapods and Gd@C_82 metallofullerene peapods are investigated by using the field effect in a gated structure. The results show that C_60 peapods exhibit unipolar p-type characteristics, whereas Gd@C_82 peapods show ...

Fullerene‐Based Immunoregulatory Nanomaterials for Immunotherapy of Tumor and Immune‐Related Inflammatory Diseases

Advanced Functional Materials, Volume 34, Issue 49, December 2, 2024.
Fullerene‐based immunomodulatory nanomaterials have a dual immunomodulatory mechanism. They activate the immune system after immunosuppression, giving them powerful roles in tumor immunotherapy and tumor‐enhancing immunotherapy. In addition, fullerene nanomaterials inhibit over‐activated immunity, developing different strategies to suppress related ...
