Influence of the Activation Parameters on the Electrochemical Performance of Chemically Activated Graphene Materials [PDF]
ECS Transactions, 2021 In this work, activated graphene-like materials were obtained by varying both the ratio of activated agent/graphene precursor and the activation temperature. The resulting materials were then characterized, resulting in higher values of specific surface area (SSA) when increasing the impregnation ratio at each temperature, reaching values up to 1325 m2

Comparison of chemical parameters of enzyme active and inactive malt types
Acta Agraria Debreceniensis, 2021 Nowadays there is an increasing emphasis on the use of raw materials. Typically, raw materials – in this study malt – are used in animal feeds and used in the brewing industry. However, in terms of quality (eg. high fibre content), these can be included in human nutrition, we have limited information on this possibility.
