A general but still unknown characteristic of active oxygen evolution electrocatalysts
(Royal Society of Chemistry, 2023-04)The unsatisfactory electrocatalysis of the oxygen evolution reaction (OER) is a major hurdle for the sustainable production of hydrogen using water electrolyzers. Besides, most state-of-the-art catalysts are based on ... -
A method to estimate the size of single-chain nanoparticles under severe crowding conditions
; ; Pomposo Alonso, José Adolfo (Royal Society of Chemistry, 2022-01-05)
[EN] Single-chain nanoparticles (SCNPs) result from the folding of isolated polymer chains via intramolecular interactions. Currently, there is no theory able to rationalize the astonishing conformational behaviour of SCNPs ... -
A perspective on ab initio modeling of polaritonic chemistry: The role of non-equilibrium effects and quantum collectivity
(AIP Publishing, 2022-06-21)This Perspective provides a brief introduction into the theoretical complexity of polaritonic chemistry, which emerges from the hybrid nature of strongly coupled light-matter states. To tackle this complexity, the importance ... -
A Review on Current Strategies for the Modulation of Thermomechanical, Barrier, and Biodegradation Properties of Poly (Butylene Succinate) (PBS) and Its Random Copolymers
Peñas Núñez, Mario Iván; Pérez Camargo, Ricardo Arpad; Hernández, Rebeca; Müller Sánchez, Alejandro Jesús (MDPI, 2022-03-03)
The impact of plastics on the environment can be mitigated by employing biobased and/or biodegradable materials (i.e., bioplastics) instead of the traditional “commodities”. In this context, poly (butylene succinate) (PBS) ... -
A Rigorous Exploration of the Plexcitonic Phenomena: Hybridized Light-Matter States using Gold Nanoparticles and J-aggregates
(2024-05-10)This work is focused on investigating the interplay between plasmon-exciton interactions within strongly coupled plexcitonic systems. Here, gold nanoparticles were used as the plasmonic component and molecular chains known ... -
A single amino acid able to promote high-temperature ring-opening polymerization by dual activation

A trade-off between ligand and strain effects optimizes the oxygen reduction activity of Pt alloys
(RSC, 2022-10-20)To optimize the performance of catalytic materials, it is paramount to elucidate the dependence of the chemical reactivity on the atomic arrangement of the catalyst surface. Therefore, identifying the nature of the active ... -
Ab initio many-body perturbation theory to study molecular systems: from implementation to applications
(2022-10-04)The theory describing the interaction between light and matter at nanoscale is nearly as old as quantum mechanics. Over the years, it has been shown that such theoretical models not only enable materials scientists to ... -
