Abstarct: Nanostructured colloidal semiconductors with heterogeneous photocatalytic behavior have drawn considerable attention over the past few years. This is due to their large surface area, high redox potential of the photogenerated charge carriers, and selective reduction/oxidation of different classes of organic compounds. In the present paper, we have carried out a systematic synthesis of...

The surface properties of TiO2-PVDF nanocomposite membranes were investigated by incorporating different chemically modified TiO2 nanoparticles into the poly (vinylidene fluoride) (PVDF) matrix. The nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. The membrane surface morphologies were investigated by using SEM and AFM and related...

Plasmonic photocatalytic nanocomposites of TiO2 and Au nanoparticles (NPs) have recently attracted the attention researchers, who aim to improve activity potential NPs. In this study, we report enhancement for a Au/TiO2 nanocomposite prepared by plasma–liquid interaction method using an atmospheric microplasma apparatus. The enhanced is demonstrated degradation methylene blue (MB) in water unde...

fe3o4 magnetic nanoparticles were synthesized by co-precipitation of fe2+ and fe3+ in aqueous naoh. then silica was coated on the obtained nanoparticles and the whole composite was functionalized with chlorosulfonic acid in ch2cl2. the obtained nanocomposite (fe3o4@sio2-so3h) was characterized by ft-ir, vsm and xrd techniques and was used as an efficient catalyst in condensation reaction of ind...

the magnetite (fe3o4) – agar nanocomposite was prepared by co-precipitation of fe (iii) and fe (ii) ions for the first time. the obtained samples were characterized by x-ray diffraction, fourier-transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. ft-ir results confirm the formation of fe3o4 nanoparticles in agar matrix. the xrd results revealed th...

The results of this study indicate that titanium dioxide nanoparticles (nano-TiO2) possess adsorptive, photocatalytic, bactericidal, virucidal and fungicidal properties, which are used in antibacterial coating, for air water disinfection. In parallel with studies the physicochemical characteristics dioxide, its toxicological assessment was carried out to prevent possible harmful effects on huma...

UNLABELLED In this work, the magnetic properties of silicon nanotubes (SiNTs) filled with Fe3O4 nanoparticles (NPs) are investigated. SiNTs with different wall thicknesses of 10 and 70 nm and an inner diameter of approximately 50 nm are prepared and filled with superparamagnetic iron oxide nanoparticles of 4 and 10 nm in diameter. The infiltration process of the NPs into the tubes and dependenc...

Uranium (U) poses a significant contamination hazard to soils, sediments, and groundwater due to its extensive use for energy production. Despite advances in modeling the risks of this toxic and radioactive element, lack of information about the mechanisms controlling U transport hinders further improvements, particularly in reducing environments where U(IV) predominates. Here we establish that...
