Recent Progress of Biomass‐Derived Nitrogen‐Doped Carbon Materials as Electrocatalysts: Carbonization, Functionalization, and Applications

open access: yesCarbon Energy, EarlyView.
Integrating renewable energy with electrochemical conversion and storage is crucial for sustainable energy solutions. Nitrogen‐doped biomass‐derived carbon materials have emerged as effective catalysts for key reactions such as ORR, HER, and CO2RR. This review explores their synthesis, functionalization, characterization, and catalytic applications ...

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

A comprehensive study devoted to determine linear thermal bridges transmittance in existing buildings

open access: yesEnergy and Buildings, 2020
Abstract The issue of transmittance of thermal bridges in existing buildings has been addressed aiming to achieve correlations able to evaluate the ground-contact thermal bridges. A bi-dimensional steady state FEM model has been implemented to simulate wall-to-floor structural node and then validated in accordance with the EN ISO 10211:2017 standard.
