A series of small chromium-doped silicon clusters CrSin with n = 3-10 in the cationic, neutral and anionic charge states were investigated using quantum chemical methods. The CrSin+ cations with n = 6-10 were produced in the gas phase and characterized by far-IR multiple photon dissociation (IR-MPD) spectroscopy. Good agreement between experimental...
L10-ordered FeNi, tetrataenite, found naturally in meteorites is a predilection for next-generation rare-earth free permanent magnetic materials. However, the synthesis of this phase remains unattainable in an industrially relevant time frame due to the sluggish diffusion of Fe and Ni near the order-disorder temperature (593 K) of L10 FeNi. The pre...

A novel nanocomposite, CDs-La-EDTA, was synthesized by bonding carbon dots to the functional sites of rare earth complexes, and its tribological characteristics were evaluated as lubricant additives. The results showed that the mean friction coefficient and the wear scar diameter of lubricating oil containing 0.15 wt% CDs-La-EDTA were reduced by 14...

Understanding hydrogen-metal interactions is important in various fields of surface science, including the aqueous corrosion of metals. The interaction between atomic H and a Mg surface is a key process for the formation of sub-surface Mg hydride, which may play an important role in Mg aqueous corrosion. In the present work, we performed first-prin...
Single-atom catalysts (SACs) are appealing next-generation catalysts for various electrochemical technologies. Along with significant breakthroughs in their initial activity, SACs now face the next challenge for their viable applications, insufficient operational stability. In this Minireview, we summarize the current knowledge of SAC degradation m...

The present work focuses on designing a robust non-noble metal-based niobia-supported catalyst with a high number of oxygen vacancies for an efficient HDO activity of anisole. Various synthesis procedures, such as hydrothermal (Nb2O5-HT), precipitation (Nb2O5-P) and hydrolysis (Nb2O5-H), are adopted for the preparation of the Nb2O5 support, followe...
Electric mobility has proven to be essential for the carbon neutrality of the transport sector. However, several studies have demonstrated the environmental costs linked to the supply of rechargeable batteries, which should not be overlooked. The supply of some elements has raised concerns, either because they are associated with environmental and ...
