Photocatalytic elimination of water pollutants using innovative titania thin film heterostructures embedding carbon quantum dots

(Corresponding) Falara P., Zourou A., Ibrahim I., (Corresponding) Kordatos K.
Topic: 
Water treatment
Titanium dioxide based photocatalysis is a well-established advanced oxidation process (AOP) that recently has expanded its borders comprising advanced reduction processes (ARPs) as well. To enhance the photocatalytic activity, titania heterostructures embedding semiconductors, or clays, or...Read more

Condensate originating from household food waste as a substrate for Microbial Fuel Cells

Kamperidis T., Pandis P., Vlachaki E., (Corresponding) Tremouli A., Lyberatos G.
Topic: 
Environmental biotechnology and bioenergy
A microbial fuel cell (MFC) is a bioreactor that converts the chemical energy of the bonds of organic compounds to electrical energy, through the catalytic reactions of microorganisms. Under anaerobic conditions various substrates have been examined using MFC technology. This study examines the...Read more

The effect of catalysts MnO2, activated carbon and fly ash on the performance of single-chamber Microbial Fuel Cells

(Corresponding) Tremouli A., Kamperidis T., Pandis P., Stathopoulos V., Ieropoulos I., Argirusis C., Lyberatos G.
Topic: 
Environmental biotechnology and bioenergy
Microbial fuel cells (MFC) are bioelectrochemical systems that convert the chemical energy contained in waste to electricity, using bacteria as catalysts. In order to boost the power output of MFCs, various approaches are feasible. This study examines the effect of using MnO2, activated carbon and...Read more

Gas mixture candidates for SF6 replacement in medium voltage switchgear: Analysis and modeling of the filling episodes

(Corresponding) Espinazo A., Lombraña J., Alonso M., Alonso R., Izcara J., Izagirre J., Pereda-Ayo B.
Topic: 
Energy technologies and sustainability
A more environmentally friendly replacement for SF6 must be found for medium voltage switchgear, as a change in European regulations will come into force soon. The mixing process of alternative binary and ternary gas mixtures is studied, which are made up of the hydrofluoroolefin HFO-1336mzz(E) (...Read more
