Environmental behavior of coated NMs: Physicochemical aspects and plant interactions.

The application of nanomaterials (NMs) depends on several characteristics, including polydispersity, shape, surface charge, and composition, among others. However, the specific surface properties of bare NMs induce aggregation, reducing their utilization. Thus, different surface coverages have been developed to avoid or minimize NMs aggregation, making them more stable for the envisioned applications.

Quantum dots of ZnSe(S) doped with copper as nanophotocatalyst in the degradation of organic dyes.

Copper-doped quantum dots of ZnSe(S) synthesized via microwave-heating conditions were used as photocatalyst in the photo-degradation of methylene blue (MB), methyl violet (MV) and victoria blue (VB) under UV irradiation (302 nm) in aqueous phase and at pH 6.5. Quantum dots were characterized by High Resolution Transmission Electron Microscopy (HR-TEM), X-ray diffraction (XRD), UV-Vis, photoluminescence and Fourier transform infrared (FT-IR) spectroscopy.

Antimicrobial nanomaterials as water disinfectant: applications, limitations and future perspectives.

Nanotechnology and its application is one of the rapidly developing sciences. As demand of fresh drinking water is increasing, nanotechnology can contribute noticeable development and improvement to water treatment process. Disinfection process is the last and most important step in water and wastewater treatment process.

Sorption study of toluene and xylene in aqueous solutions by recycled tires crumb rubber.

Sorption of toluene and xylene by tire crumb rubber (TCR) and its main components: carbon black (CB) and styrene-butadiene polymer (SBP) were evaluated. The 12 starting concentrations of adsorbates in aqueous solutions ranged from 0.05 mg/L to 100.

Synthesis of size-controlled cobalt ferrite particles with high coercivity and squareness ratio.

Cobalt ferrite particles with diameters ranging from a few micrometer to about 15 nm were synthesized using a modified oxidation process. The fine control of the particle size was achieved by introducing various concentrations of Fe(3+) ions at the beginning of the reaction. Among the particle sizes obtained by using this method, particles with a grain size of about 36 nm showed a magnetization (M(s)) of 64 emu/g and a maximum coercivity (H(c)) of 2020 Oe at room temperature.
