A method to estimate the size of single-chain nanoparticles under severe crowding conditions
(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
(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 single amino acid able to promote high-temperature ring-opening polymerization by dual activation
(Wiley, 2024-04)Amino acids are indispensable compounds in the body, performing several biological processes that enable proper functioning. In this work, it is demonstrated that a single amino acid, taurine, is also able to promote the ... -
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 ... -
