A systemic study for enhanced waste heat recovery and renewable energy integration towards decarbonizing the aluminium industry

François Maréchal, Daniel Alexander Florez Orrego, Réginald Germanier

The aluminium remelting industry relies on natural gas to transform recycled aluminium into aluminium feedstock, entailing significant atmospheric emissions. Hydric resources are also affected as they are used as sinks of waste heat from the casting proces ...

A data-science approach to predict the heat capacity of nanoporous materials

Berend Smit, Susana Garcia Lopez, Elias Moubarak, Balázs Álmos Novotny, Seyedmohamad Moosavi, Daniele Ongari, Mehrdad Asgari, Andres Adolfo Ortega Guerrero, Özge Kadioglu

The heat capacity of a material is a fundamental property of great practical importance. For example, in a carbon capture process, the heat required to regenerate a solid sorbent is directly related to the heat capacity of the material. However, for most m ...

SIRT7 suppresses energy expenditure and thermogenesis by regulating brown adipose tissue functions in mice

Johan Auwerx

Brown adipose tissue plays a central role in the regulation of the energy balance by expending energy to produce heat. NAD(+)-dependent deacylase sirtuins have widely been recognized as positive regulators of brown adipose tissue thermogenesis. However, he ...
