ANÁLISE COMPARATIVA ENTRE UM SISTEMA SOLAR COM RASTREIO E UM FIXO

open access: yesConexões: Ciência e Tecnologia, 2020
A energia solar é uma fonte alternativa às fontes tradicionais que vem ganhando espaço ano após ano. A partir da conversão da radiação solar incidente em um módulo fotovoltaico é possível obter energia elétrica. No entanto a baixa eficiência na conversão

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

open access: yesIbis, EarlyView.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Regulating Ligand‐to‐Metal Charge Transfer in UiO‐66(Zr)‐NH2 With Site‐Isolated Cu+ Centers for Efficient Photocatalytic H2O2 Generation

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
Incorporation of highly dispersed Cu species into UiO‐66(Zr)‐NH2 introduces a competing ligand‐to‐Cu charge–transfer pathway that suppresses charge recombination and enhances photocatalytic H2O2 production. Combined PL, TRPL, TRIR, and variable‐temperature FTIR analyses reveal Cu‐mediated modulation of excited‐state dynamics and oxygen reduction ...
