Towards sustainable fuels and chemicals through the electrochemical reduction of CO2: lessons from water electrolysis

This Perspective discusses target parameters for the electroreduction of CO2, based on its comparison with water splitting, which is to become a practical alternative for energy storage into fuels and chemicals.

Critical Review

Do we need Green Analytical Chemistry?

There is very strong opinion that Green Analytical Chemistry is needed beside so-called common Analytical Chemistry. However, the developments in Analytical Chemistry must lead to environmentally safe, economical and cost-effective methods on the whole.

Retracted Article: Bigger data open innovation: potential applications of value-added products from milk and sustainable valorization of by-products from the dairy industry

Milk is a natural suspension of essential nutrients and can be exploited not only as a beverage consumed directly or transformed into a range of traditional dairy foods, for food and non-food product innovation and environmental benefits.
