Intelligent food packaging can help reduce food waste by providing consumers real-time information about product freshness. They can be produced using natural pigments with pH-dependent color changes, which makes them promising candidates for colorimetric sensors. This study reports the development,&#...

Electrochemical CO2 reduction to formate (HCOO-) represents an efficient strategy to mitigate CO2 emissions while producing value-added chemicals. However, the reaction typically requires high overpotential and suffers from low selectivity and current density. This work reports the development of Bi2O...

The extensive use of herbicides such as imazapic, from the imidazolinone class, raises environmental concerns due to its persistence and toxicity in ecosystems and subsequent crops. Enzymatic bioremediation emerges as a sustainable alterna tive for the mitigation of these contaminants. This ...
