Interactions between Plants and Rare Earth Oxide Nanoparticles
(Corresponding) Zhang Z.
Topic:
Nanomaterials in the environmnents applications and effects
Rare earth oxide nanoparticles (REO NPs) can be released into the environment from various application routes, but their effects on the ecosystem are still little known. In this study, we exposed cucumber seedlings to suspensions of La2O3 and CeO2 NPs for 14 d. Phytotoxicity of the two REO NPs was...Read more
Magnetite nanoparticles activated coal fly ash zeolites with application in waste water remediation
(Corresponding) Boycheva S., Miteva S., Trendafilova I., Zgureva D., Václavíková M., Popova M.
Topic:
Wastewater treatment
The application of zeolites in wastewater treatment is studied long ago but still many unexploited opportunities exist. Recent investigations on natural and synthetic zeolites in water decontamination are focused on the improvement of their adsorption and ion-exchange properties modifying them by...Read more

Reduction of Halogenated Organic Compounds in Water: Comparison of Available Reduction Systems based on Cu, Pd and ZVI
(Corresponding) Shee A., Kopinke F., Mackenzie K.
Topic:
Water treatment
Catalysts on the basis of copper (Cu) and the reducing agent borohydride (BH4-) have been successfully used for reduction of chlorinated aliphatics with low substitution degree which are usually resistant to zero-valent iron (ZVI) and hydrodehalogenation catalysts, such as Pd. Reactivity screening...Read more
Soil and groundwater contamination and remediation
Majority of terrestrial soils are used primarily for agricultural production. The main factor of soil fertility is mediated by soil microorganisms and invertebrates. Soil microorganisms plays crutial role in ecosystems nutrient cycling and therefore any change in their diversity could have serious...Read more
COMPLEX APPROACH FOR ANALYSIS OF CHANGES IN SOIL MICROBIOME
(Corresponding) Macůrková A., Drobníková T., Maryška L., Jindřichová B., Burketová L., Siegel J., Valentová O., Lovecká P.
Topic:
Soil and groundwater contamination and remediation
In the few past decades, genetic approaches for analysis of soil microbiome, e.g pyrosequencing, gained major attention and cultivation techniques were pushed into the background. The combination of several techniques could be useful and cheap approach for analysis of changes in soil microbiome. In...Read more
Effects of sunscreens on plants: Impact of TiO2 nanoparticles on the phytoremediation of oxybenzone
(Corresponding) Schröder P., Chen F.
Topic:
Emerging pollutants
Increasing levels of sunscreens have been found in surface waters, and in waste water. In most cases mixtures of organic and inorganic sunscreen compounds can be detected. Wetland plants, and vegetation along shores have been used as biological filters for this kind of pollution along beaches, and...Read more
Preparation of carbon nanotubes from plastic solid wastes over magnetic nickel ferrite catalysts
Lopes J., Roman F., Santos Silva A., (Corresponding) Diaz de Tuesta J., Lenzi G., (Corresponding) Silva A., (Corresponding) Faria J., Gomes H.
Topic:
Solid waste management
This work presents the development of magnetic carbon nanotubes (MCNTs) from plastic solid waste (PSW). For this purpose, diverse catalytic nanoparticles based on Fe, Ni and Al were prepared by impregnation of alumina or co-precipitation of Ni, Fe and Al nitrate salts with NH4OH, followed by...Read more

Magnetic CoFe2O4@carbon yolk-shell nanoparticles as catalysts for the catalytic wet peroxide of paracetamol
Silva A., Costa Guari N., Diaz de Tuesta J., Eno Pottker W., Yassue Cordeiro P., (Corresponding) Gomes H.
Topic:
Advanced oxidation processes
This work focuses the use of carbon-coated magnetic cobalt ferrite nanoparticles as catalysts for catalytic wet peroxide oxidation (CWPO) of the emerging pollutant paracetamol. A magnetic core composed of CoFe2O4 is developed by a sol-gel method. The core is subsequently coated with a formaldehyde-...Read more
Synthesis and characterization of nanomagnetite for environmental applications
(Corresponding) Mystrioti C., Papassiopi N., Xenidis A.
Topic:
Environmental applications of nanomaterials
Μagnetite (Fe3O4) in nanoscale has been very attractive due to its unique properties which make it ideal for a wide range of applications. Nanomagnetite can be applied as drug delivery medium, as catalyst and as efficient adsorbent and reducing agent for water treatment. In this study, magnetite...Read more

Synthesis of Fe3O4-Ag Nanocomposite and Their Performance as Surface Modifiers for TiO2 Membranes in Treating Oily Wastewater
Aboulella A., Wadi V., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Water treatment
Membrane technology has shown extraordinary performance in treating oily wastewater. Yet, more research is focused towards enhancing the performance of the separation process. In this work, Fe3O4-Ag composite nanoparticles (NPs) were synthesized using the co-precipitation technique and applied on...Read more
