    “…First, the strategies used in the group with respect to three key factors in photocatalysis, including light harvesting, charge separation, and reactant adsorption/product desorption, are comprehensively analyzed with the aim to provide a clear strategy for efficient photocatalyst design toward small and robust molecule photoactivation under ambient conditions. The application of in situ and operando techniques on charge carrier dynamics and reaction pathway analysis used in the group are next discussed. …”

    “…Different working mechanisms related to Na(x)TMO(2) are summarized, including the electrochemical reversibility, the main structural transformations during the charge and discharge processes, and the charge-compensation mechanisms that accompany the (de)intercalation of Na(+) ions, followed by discussions to improve the stability toward ambient air and upon cycling. Then the techno-economics are presented, with an emphasis on cathodes with different chemical compositions, cost breakdown of battery packs, and Na deficiency, factors that are critical to the large-scale implementation. …”

    “…Es por ello que, según afirman ciertos especialistas en didáctica, el temor a cometer una falta puede causar ansiedad en el estudiante y contribuir a crear un ambiente poco propicio para el aprendizaje. Por lo tanto, es conveniente diferenciar la falta respecto del error: la primera puede ser considerada como inhibitoria y como sinónimo de fracaso, mientras que el segundo puede servir como fundamento para una “reconstrucción” del conocimiento. …”
