The main joining process of the electronic industry is still soldering with different alloys Sn. This work studied relationship between Sn whisker growth and corrosion resistance 99Sn0.3Ag0.7Cu–TiO2/ZnO (0.25wt%) composite solder in a corrosive environment via scanning electron microscopy focused ion beam techniques. test showed that application TiO2 ZnO nano-particles almost totally suppressed...

In this work, two natural dyes extracted from henna and mallow plants with a maximum absorbance at 665 nm were studied and used as sensitizers in the fabrication of dye-sensitized solar cells (DSSCs). Fourier transform infrared (FTIR) spectra of the extract revealed the presence of anchoring groups and coloring constituents. Two different structures were prepared by chemical bath deposition (CB...

Water borne pathogens present a threat to human health and their disinfection from water poses a challenge, prompting search for newer methods and newer materials. Disinfection of Gram-negative bacterium Escherichia coli and Gram-positive coccal bacterium Staphylococcus aureus in aqueous matrix was achieved within 60 and 90 minutes respectively at 350C using solarphotocatalysis mediated by sono...

Bisphenol A, bisphenol S, and fluconazole are environmental contaminants widely found in surface waters because of their extensive usage low biodegradability. Therefore, other methods often considered for the removal these compounds. The present study aims at photodegradation with use UV light three different catalysts, ZnO, TiO2, Ag-TiO2. results obtained show that photocatalytic compounds is ...

One of the drawbacks of typical dye-sensitized solar cells (DSCs) is their high cost and the high electrical resistance of the transparent conducting substrate. In conventional sandwich-type DSCs, only one of the FTO substrates can be replaced by a metal substrate. We investigated an all-metal-electrode single-sided DSC in which interpenetrated bracken-like Cr electrodes were created using phot...

Titanium dioxide (TiO2) and zinc oxide (ZnO) are among the most used catalysts in photodegradation. Paracetamol salicylic acid widely as pharmaceutical drugs. We found that paracetamol is less susceptible to photodegradation compared acid. From a chemical perspective, this was not expected since more vulnerable oxidation. Aiming comprehension of phenomenon, studies were performed comparing effi...

Organic UV filters have been known to generate harmful by-products and undergo photoreactive degradation, which ultimately poses a great threat consumers using sunscreen products. Inorganic such as TiO2 ZnO, although considered safer options, are not without considering their photocatalytic nature ability reactive oxygen species. A study was conducted identify the influence of different metal i...
