Nitrogen co-doped with fluorine on reduced graphene oxide for enhanced electrocatalytic activity and stability for ORR in alkaline fuel cells
Musico Y., Labata M., (Corresponding) Chuang P., Ocon J.
Topic:
Energy technologies and sustainability
Nitrogen co-doped with fluorine on reduced graphene oxide (rGO) was prepared by one-pot hydrothermal treatment method. The scanning electron microscopy (SEM) images and X-ray photoelectron microscopy (XPS) spectra revealed the successful doping of nitrogen and fluorine into the rGO. The Brunauer-...Read more
Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...Read more

Modelling the hydrothermal carbonization of cheese whey wastewater in Lesvos island: an application of the 3-step evolution model
Chatzimaliakas P., (Corresponding) Vakalis S.
Topic:
Biowaste
Lesvos island has an extensive dairy production sector, and -at present- eighteen dairy processing facilities are operating. Efficient management of the liquid biowaste effluents has been an issue of interest since the scope is the minimization of the environmental impact. The operating dairy...Read more

A first insight of Hg occurrence in the hellenic volcanic arc
(Corresponding) Anagnostou E., Stathopoulou E., Heimbürger-Boavida L., Nomikou P.
Topic:
Heavy metals in the environment
Mercury is a highly toxic element with both natural and anthropogenic sources to the marine environment, with implications to ecosystems and human health. It is recognized as a priority pollutant by the European Environmental Legislation and the United Nations Environmental Program (UNEP). The...Read more
