“…The microbiologic studies demonstrated that yeast cells deposited in a glass surface exposed to 15 minutes of UV light (254nm) reached a 34% inhibition growth, and yeast cells on a SnO2 thin film, exposed to the same amount of UV radiation reached a 66% growth inhibition, results that were expected according to SnO2 photocatalytic activity reported in the scientific literature [2,5,6]. A comparison between yeast cells deposited on SnO2 thin films, with and without exposure to UV light, is shown in Figure 2c-d…”

“…UV light has been used for decades as a very efficient wide range antimicrobial method, and resistance mechanisms had not been an important factor that could affect disinfection performance. Certain metal oxides, like SnO2 have photocatalytic properties that allow them to increase the efficacy of UV light antimicrobial activity [5][6][7]. In the present work antibacterial testing was performed employing SnO2 substrate coupled with UV light to measure the ensemble activity against C. albicans a common pathogen in the hospital environment from the microbiologic and scanning electron microscopy perspective.…”

“…However, most published works only focused on the micro-sized ZnO particles, with a very limited photocatalytic behavior in the coating system. In the case of the nanocomposite coating, their antimicrobial activity and self-cleaning ability could be achieved, with nano-ZnO being the most promising and effective photocatalyst [ 18 , 19 , 20 , 21 ]. As reported, after absorbing UV radiation, an electron of ZnO at the valence band jumps into the conduction band, creating an h + hole [ 22 ].…”

This work aims to explore how ZnO nanoparticles enhance the mechanical, photoaging, and self‑cleaning properties of water‑borne acrylic coating. Micro/nano‑ZnO particles (at 2 wt.% of total solid resin) were dispersed into the acrylic polymer matrices using ultrasonication to understand the effect of the size of the coating properties. The effect of ZnO particles on the properties of composite coatings (25 µm of thick) have been evaluated through various tests, such as abrasion measurement, ultraviolet/condensation (UV/CON) weathering aging, and methylene blue self‑cleaning. Experimental data indicated that the incorporation of ZnO particles enhanced both abrasion resistance and methylene blue removal efficiency of the water‑borne acrylic coatings, with nano‑ZnO particles being the best. However, the weathering degradation of nanocomposite coatings was more severe as compared to the coating with micro‑ZnO (at the same ZnO content).

“…This rate of formation of ferric oxide compounds purely depends on the preexisting holes available for the electrolyte percolation. If these corrosive pore domains are coated with the heterogeneous rough atoms like nitrogen or silica, the rate of ferrous oxide production will be highly reduced [15]. In accordance with the increase of printed circuit board powder in the mixture, the corrosion resistance efficiency of the coating increases.…”

The growth in the industrial technology and communication sectors has enhanced the usage of electronic gadgets exponentially. Thus, it becomes highly essential to find new solution to utilize or dispose these e-wastes, in order to reduce the e-waste generation. Various reports mentioned that the major component of these e-wastes is their Printed Circuit Boards. Therefore, a new ideology is proposed to use these boards to produce a new coating with good corrosion resistance. At first the boards were separated from the discarded electronic appliances and various electrical elements were separated from these boards. Then the plain circuit boards are pulverized into fine particles and mixed with paint in 3 different proportions ranging from 1:4 to 1:2. The resulting mix was applied over the steel specimen and tested for corrosion resistance. The assessment was done in the aspects of contact angle, weight loss percentage, potentio dynamic polarization technique and electro chemical impedance spectroscopy. From the results it was clear that increase in the addition of printed circuit powder content in the corrosion proof paint coating enhanced the efficiency of the corrosion resistant behaviour 3.5 times than the specimen with uncoated steel specimens. This development of corrosion resistant behaviour of printed circuit powder was attributed from the inertness offered by the presence of silicon dioxides towards the corrosive fluids. Although, the coating of 1:2 proved to be optimum to protect the steel elements from the aggressive corrosion environment, by considering the workability aspects the 1:3 combination was suggested for the innovative development of anti-corrosion paint coating from the e-waste resources. HIGHLIGHTS Life cycles of every electronic wastes end with the hazardous challenging disposals Innovative utilizations of these electronic wastes for the corrosion resistant structural applications were detailed An anti corrosive coating for steel reinforcement was developed from the waste printed circuit boards Coating by printed circuit board powder enhanced 3.5 times more protection from the corrosion GRAPHICAL ABSTRACT
