Theoretical approach to the one-step versus two-step spin transitions in Hofmann-like FeII SCO metal-organic frameworks
(Elsevier, 2023-06)
Guest molecules in the 3D Hofmann-type FeII spin-crossover (SCO) metal-organic frameworks modulate the magnetic properties of the host, modifying the spin state, transition temperature, width of the hysteresis loop and ...

Understanding gold nanoparticles interactions with chitosan: Crosslinking agents as novel strategy for direct covalent immobilization of biomolecules on metallic surfaces
(Elsevier, 2020-03-15)
The development of a new method for covalent immobilization of biomolecules on the surface of bare gold nanoparticles (AuNPs) by using crosslinking agents in one step is presented. A very compatible biopolymer such ...

Copper-nitroxide based breathing crystals: a unified mechanism of gradual magnetostructural transition supported by quantum chemistry calculations
(Royal Society of Chemistry, 2019)
The molecular magnets Cu(hfac)2LR based on copper(II) and pyrazolyl-substituted nitronyl nitroxide radicals LR exhibit thermally and optically-induced magnetostructural transitions, similar to the spin-crossover and ...

Adsorption and activation of CO2 on Pt/CeOx/TiO2(110): Role of the Pt-CeOx interface
(Elsevier, 2021)
The adsorption and dissociation of CO2 on TiO2(110), CeOx/TiO2(110) and Pt/CeOx/TiO2(110) surfaces has been examined using Ambient Pressure X-ray Photoelectron Spectroscopy (AP-XPS). The substrates under study exhibited ...
