Background: Natural organic matter (NOM) in drinking water sources has always been regarded as a precursor for the formation of trihalomethanes (THMs), haloacetic acids (HAAs), and carcinogenic properties. This study aimed to fabricate characterize nanohybrid ultrafiltration membrane (PSF/ZnO) evaluate its efficiency NOM removal from water. Methods: Nanohybrid membranes with ratios 0, 1, 2, 3 4...

Chemiresistive sensors are promising devices for sensing hydrogen gas in a broad range of applications including fuel cells, storage systems, petroleum refinement, and diagnosis oil-insulated transformers. Herein, electrospun ZnO–SnO2 belts (BLs) were synthesized applied as resistive-type layers sensing. The BLs containing 20 mol% Zn relative to Sn showed response (Ra/Rg, Ra: resistance air, Rg...

This research investigated the production of porous zinc oxide (ZnO) ceramics obtained by replica method for water depollution photocatalytic processes. Five photo-decolorization cycles were performed to analyze reuse potential ceramics. Statistical analyses using R programming conducted investigate possible significant differences between them. The porosities 46.74 and 62.50% (depending on com...

We report on the photocatalytic activity of ZnO layers deposited by atomic layer deposition a porous anodic aluminum oxide substrate with hexagonal pore symmetry and varied dimensions. ZnO/Al2O3 composites were prepared diameters in range 93–134 nm interpore distance 185–286 nm, their was measured for gas-phase oxidation acetaldehyde at varying UV illumination intensities (0.08–3.94 mW cm?2). T...

Low conversion efficiency is still the main limiting factor for current solar-cell technologies. A large portion of the energy loss during solar-cell operation is attributed to optical loss, namely the loss of the incoming light by reflection.[1] To reduce the reflection loss, surface texturing and antireflection coatings are the most-commonly used strategies.[2–4] Surface texturing is able to ...
