Fluoride-free Anodization of Titanium and the Photocatalytic Behaviour the Produced TiO2 Nanostructures
Taylor C., (Corresponding) Wenk J., Mattia D.
Topic:
Advanced oxidation processes
Current methods for anodizing titania to produce immobilized titanium dioxide (TiO2) photocatalyst require the use of hazardous fluoride electrolytes. A fluoride-free electrolyte anodization method was developed. The electrolytes tested in this study were both bromide- and chloride-based and...Read more
Coal ash zeolite as a self-catalytic-chemisorption system for conversion of carbon dioxide to hydrocarbons
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
At present, the developments of sustainable carbon capture technologies are of the main scientific and technological priority required to mitigate the over generation of greenhouse gases. Three CO2 clean energy production approaches have been outlined: pre-combustion capture, oxy-fuel combustion...Read more

Durability of cement mortars and concretes exposed to biological attack as one of the sustainability parameter – a correlation analysis
(Corresponding) Ondrejka Harbulakova V., Estokova A., Smolakova M., Luptakova A.
Topic:
Energy technologies and sustainability
Among the pillars of the sustainability, the aspect of prolongation of life of constructions has to be involved. Focus on sustainability of construction leads to study of durability of building materials. Phenomenon called biocorrosion, existing mainly in concrete sewer systems, agricultural...Read more
Green sonochemical route for the synthesis of MOFs for the electrochemical reduction of CO2
(Corresponding) VAITSIS C., KANELLOU E., PANDIS P., SOURKOUNI G., ZORPAS A., (Corresponding) ARGIRUSIS C.
Topic:
Gas emissions control and utilization
A zinc-based MOF has been prepared by utilizing adipic acid as an aliphatic ditopic linker via both solvothermal and sonochemical methods. The ultrasound irradiation has reduced the reaction time and has led to smaller particle size. The samples were evaluated for their catalytic efficiency by the...Read more
Histopathological alteration in gills and liver of Cyprinus Carpio after a short-term exposure to titanium dioxide nanoparticles
(Corresponding) Iftikhar N., Hashmi I.
Topic:
Ecological effects of environmental change
With the rapid development of nanotechnology in past few decades, engineered nanomaterials (ENMs) have been extensively used in variety of domestic, commercial, and industrial products. Nano-titanium dioxide is one of the most widely used nano-material due to its UV light absorption, optical...Read more

Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids
(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...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
Ground based integrated path differential absorption sensor for remote sensing of CO2, CH4 and H2O atmospheric greenhouse gases
(Corresponding) Panagiotis S., Psyllakis G., Samartzis P., Velegrakis M.
Topic:
Environmental odour, monitoring and control
An autonomous, ground-based, integrated path, differential absorption light detection (IPDA) system is presented, capable of measuring multiple gases concentration in the atmosphere. The device was developed to monitor small scale locations with high greenhouse gases emissions and is equipped with...Read more
CO2 absorption into 4-diethylamino-2-butanol solution in a membrane contactor under wetting or non-wetting conditions
Li L., Pan Z., Baena-Moreno F., Borhani T., (Corresponding) Zhang Z.
Topic:
Gas emissions control and utilization
Natural gas produces a large amount of carbon emissions in the process of mining and processing, on the one hand from the energy use of processing facilities, on the other hand from the way that natural gas is extracted. The adoption of appropriate carbon capture technology is of urgency. The...Read more
CO2 and NO2 distributions over Greece as seen by OCO-2 and TROPOMI
Gialesakis N., Daskalakis N., (Corresponding) Kanakidou M.
Topic:
Climpact: national network for climate change and its impacts
Greenhouse gases are the driving force behind human-induced global warming. Carbon dioxide (CO2) is the greenhouse gas (GHG) with the longer lifetime in the atmosphere, in the order of hundreds of years, and the largest contribution to the radiative forcing of the atmosphere due to its increasing...Read more
