CO2 electroreduction (eCO2R) into fuel products is a promising technology to mitigate the effects of greenhouse gas emissions and store renewable energy. The main metal-based electrocatalysts widely employed in CO2 reduction are characterized by high overpotentials, low stability, and unsatisfactory selectivity. As a result, a growing interest in the use of boron-doped diamond (BDD)-based electrocatalysts have been observed due to its excellent properties. This review sheds light on the techniques applied toward the eCO2R on BDD surface and the effects of the operational conditions. Particular emphasis will be given on recent advances made in the quest for enhancing the performance of BDD in eCO2R through its modification with defects insertion or functionalization with metal-based materials. The review will also present a brief overview of the challenges and directions of future research with respect to the development of different electrochemical systems for eCO2R on BDD electrod |

Modeling the growth of Bertholletia excelsa Bonpl. (B. excelsa) trees in natural forests is important for understanding the species? ecology and for better defining site-specific management. In this sense, this study aimed to model the diameter growth rate of B. excelsa trees in contrasting forest environments in the Brazilian Amazon. This study was conducted in the Extractive Reserve Rio Cajari (RESEX Cajari). Growth models were fitted at species level to predict diameter growth rate in the two Amazonian forest environments. Subsequently, the age at which the B. excelsa tree in each forest environment reaches the minimum diameter for seed production was calculated by integrating the growth models. In each forest environment, the negative exponential behavior of the diametric growth rate of the tree species was fitted by an appropriate model. The time required for B. excelsa trees to reach the minimum diameter was shorter in the secondary forest environment when compared with that of the old growth terra firme forest (47 and 78 years to reach the diameter of 25 cm in the secondary and old growth terra firme forest, respectively). While the average growth pattern indicated higher diameter growth rates of B. excelsa in the secondary forest environment, the high level of uncertainty in the model?s estimation makes this inference complex. In conclusion, the secondary forest seems a favorable forest environment for the growth of B. excelsa trees, which may be an indicator of the potential for secondary forest environments to produce B. excelsa seeds in the future.
