Metal complexes with naphthalene-diimide and perylene-diimide-based ligands: supramolecular interactions and catalytic implications
This doctoral thesis delves into the design and development of new ligand precursors and organometallic complexes through the combination of two different types of rylene-diimides (RDIs), with N-heterocyclic carbene ...
Unraveling the mechanism of CH3CH2OH dehydrogenation on m-ZrO2(111) surface, Au13 cluster, and Au13 cluster/m-ZrO2(111) surface: a DFT and microkinetic modeling study
In this study, we investigate the dehydrogenation of ethanol and the production of CH3CHO and H2 on the m-ZrO2(111) surface, an Au13 cluster, and Au13/m-ZrO2(111) surface, using density functional theory simulations. Our ...
Biomaterials based on LMWG-polymer multicomponent supramolecular hydrogels
Supramolecular hydrogels are formed through the self-assembly of low-molecular-weight gelators (LMWGs) in water, creating three-dimensional fiber networks via non-covalent interactions. The primary drawback of supramolecular ...
Impacto del ejercicio de Ultra Trail sobre el estado oxidativo del plasma y su relación con el daño muscular y la aparición de fatiga en una muestra de corredores amateurs
El estrés oxidativo se ha estudiado ampliamente en asociación con los deportes de ultrarresistencia sin que haya un consenso sobre las repercusiones del mismo. El objetivo de este estudio fue dilucidar el impacto de una ...
Developing mitigation strategies to alleviate abiotic stress conditions in citrus plants
The climate change situation has worsened in recent decades, and this has negatively affected certain economic activities, particularly agriculture. Crops have been impacted by heatwaves, exposure to high light intensity, ...
Supramolecular materials based on short peptides: design, synthesis and applications
In this study, we planned to obtain supramolecular materials based on short peptides with a low-cost and high-efficiency synthesis procedure, which have an acceptable toxicity rate and can be applied in biological systems ...
Síndrome metabólico y abuso de alcohol: efectos de la acción combinada de ambas patologías en el balance oxidativo del sistema nervioso central
El síndrome metabólico es un clúster de anormalidades fisiológicas y bioquímicas entre las que se incluyen la resistencia a la insulina, obesidad central, dislipidemia, hipertensión e intolerancia a la glucosa. El consumo ...
