Cooperation of bacteria and fungus on polycyclic aromatic hydrocarbons degradation
(Corresponding) Vrchotová B., Danda M., Lovecká P.
Topic:
Soil and groundwater contamination and remediation
Polycyclic aromatic hydrocarbons are diverse family of hydrophobic organic pollutants. They can be removed from environment by bacterial degradation. One of the process which could limit biodegradation is transfer of hydrophobic contaminants in to aqueous phase were degrading microorganisms live...Read more
Degradation of textile dyes in water by gas-liquid NSP-DBD plasma
MEROPOULIS S., (Corresponding) AGGELOPOULOS C.
Topic:
Advanced oxidation processes
Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more
Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...Read more

Kinetics study of the MO adsorption and photocatalytic degradation using an effectively engineered HF photocatalyst
(Corresponding) Theodorakopoulos G., Katsaros F., Papageorgiou S., Romanos G.
Topic:
Water treatment
In this study, copper decorated photocatalysts (Degussa P25), were shaped in the form of ceramic hollow fibers (HFs) and their photocatalytic properties were investigated using Methyl Orange (MO), a prototype anionic pollutant. The abatement of the dye was tested in dark and under UV irradiation by...Read more

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
ANALYTICAL DEVELOPMENTS FOR PVC RADIOOXIDATION STUDY, IN SIMULATED DISPOSAL CONDITIONS
(Corresponding) Chantreux M., Rossignol S., Ricard D., Bussière P., Therias S., Gardette J., Wong-Wah-Chung P.
Topic:
Hazardous waste management
Radioactive waste is generated by the use of radioactive materials in industry, research and medicine, as well as in nuclear power plant. The management and disposal of such waste is, therefore, a very important issue. In France, the estimated volume for the low intermediate-level long-lived...Read more
Photocatalytic Removal of Pesticides Present in Agro-industrial Water Effluents
Arfanis M., Theodorakopoulos G., Anagnostopoulos C., Georgaki I., Liappis K., Romanos G., Markellou E., (Corresponding) Falaras P.
Topic:
Wastewater treatment
Pesticide residues accumulated in agricultural wastewaters constitute a potential risk for the environment and the human health. Hence, focused actions for their elimination are of high priority for both the industry and national authorities. This work evaluates the effectiveness of the...Read more

Topic:
Air pollution
Headspace solid-phase micro extraction-gas chromatography/mass spectrometry (HS-SPME-GC/MS) was performed for the analysis of volatile organic compounds (VOCs) emitted from books. Towards this, books of different ages were examined (old = 50-300 years and new = 2-25 years) using a CAR/PDMS fiber...Read more
Decomposition products of 1,3,3,3-tetrafluoropropene and perfluoro-(3-methylbutan-2-one) gas mixtures in medium voltage electrical switchgear. Alternatives to SF6
(Corresponding) Alonso M., Alosno R., Espinazo A., Lombraña J., Izcara J., Izagirre J.
Topic:
Energy technologies and sustainability
In this work, binary and ternary gas mixtures of 1,3,3,3-tetrafluoropropene, HFO-1234ze(E), and perfluoro-3-methylbutan-2-one, CF3C(O)CF(CF3)2, with CO2 and synthetic air, are presented as alternatives to SF6 in medium voltage electrical equipment. They were used in four medium voltage switchgear...Read more
Photocatalytic degradation of magenta effluent from the printing industry with composite catalyst
(Corresponding) Kerkez D., Pucar Milidrag D., Bečelić-Tomin M., Gvoić V., Kulić Mandić A., Leovac Maćerak A., Tomašević Pilipović D.
Topic:
Wastewater treatment
Water pollution is one of the most current problems related to human life and survival. The high degree of pollution of the human environment is contributed, among other things, by the discharge of industrial wastewater into rivers, among which wastewater from the graphic industry is of great...Read more
