“…In the few last decades, the raised of utilized from the photocatalysts and nanocatalysts was regarded as versatile materials such as produced of solar cells [1][2], decolorized and degradation of organic compounds [3][4][5][6][7][8] used as biosensor [9][10], synthesis some organic compounds in certain reactions [11], using as anticancer and antitumor [12][13], and using in SPF solar emulsions as sunscreen [14][15].…”

The aim of this manuscript was to modify the ZnS surface by incorporating with CdS photocatalyst. This manner led to depressing the recombination process and increasing the activity. The X-ray Powder Diffraction (XRD) data were proved that the CdS incorporated with ZnS and formed ZnS-CdS nanocomposite by observing new peaks at 26.92, 28.62, 30.52, and 47.26°. Based on the Atomic Force Microscopy (AFM) analysis and Tauc equation, the particle sizes for all samples were raised with decreased the band gap values. The activation energy for decolorization of Congo red with the using ZnS is found to be more than that value for the using prepared ZnS-CdS composite. The percentage of efficiency was found to be increased with modified the ZnS surface.

“…1.7.7 software. [18][19][20] By considering the phase structure selection as magnetic structure representation, electrical resistivity characteristic of Fe3O4 and γ-Fe2O3 compounds should be considered. However, because γ-Fe2O3 has about a 100 times higher resistivity than that of Fe3O4, [21][22] we only used Fe3O4 as a representative magnetic crystal structure.…”

In this work, polyvinyl alcohol (PVA)-coated Fe3O4 (PVA-Fe3O4) and PVA-grafted Fe3O4 using glutaraldehyde (GA) as a crosslinker (PVA-GA-Fe3O4) were prepared. These two materials were prepared by in-situ coprecipitation method due to the simplicity synthesis procedures which accompanied with mild and clean conditions to produce excellent materials. The effects of preparation and synthesis conditions toward the characteristics of PVA-Fe3O4, and PVA-GA-Fe3O4 nanoparticles were investigated in detail. Then, the resulted nanoparticles of PVA-Fe3O4 and PVA-GA-Fe3O4 were characterized by Fourier transform infrared spectroscopy (FTIR), electron spin resonance (ESR) spectroscopy, and X-ray diffraction (XRD). The result showed that PVA with and without crosslinker was successfully coated onto the surface of Fe3O4 nanoparticles. Increasing PVA concentration triggered a decline in the abundance of Fe3O4 phase, its lattice parameter and magnetism. However, once GA as crosslinker was added to the system, the amount of Fe3O4 phase, its lattice parameter and magnetism raised whereas its crystallite size decreased. The influence of each crystallographic parameter on their magnetism was discussed systematically in detail.

“…The current popular solution in reducing environmental pollution is using a photocatalyst. TiO2 photocatalysts are able to degrade environmental pollutants such as indigo carmine dyes [12], basic yellow (BY13) [13], diazinon pesticides [14], acetaminophen [15] and amoxicillin antibiotics [16,17]. Research on the degradation of ciprofloxacin using TiO2 nanoparticles continues.…”

The popular use of ciprofloxacin is often irrational, so it causes environmental pollution such as resistance. The solution to overcome environmental pollution due to ciprofloxacin is degradation by using TiO2 nanoparticles. TiO2 nanoparticles performance is influenced by environment such as light source, pH solvent, duration of lighting and TiO2 nanoparticles mass. The residual levels determination of ciprofloxacin was carried out by using a UV-Vis spectrophotometer. Toxicity test of ciprofloxacin degradation products with TiO2 nanoparticles used Escherichia coli bacteria. Liquid Chromatography Mass Spectrometry (LCMS) was used to determine the type of ciprofloxacin degradation product with TiO2 nanoparticles. The optimum condition for the ciprofloxacin degradation with TiO2 nanoparticles is lighting for 5 hours by using a white mercury UV lamp and 50 mg TiO2 nanoparticles with pH solvent of 5.5. The toxicity of ciprofloxacin degradation product with TiO2 nanoparticles was low. The smallest degradation product identified with m/z was p-fluoraniline (m/z 111).
