The photoactivated periodate (UV/IO4−) process is used to investigate the degradation of acid orange 10 (AO10) dye. photodecomposition ions produces highly reactive radicals (i.e., •OH, IO3•, and IO4•) that accelerate dye degradation. Increasing initial concentration 3 mM enhances removal rate, but over periodate, rate slows down. On contrary, increasing concentrations reduces performance. pH m...

This work focuses on the preparation and characterization of activated carbon/hematite (AC/?-Fe2O3) composite for use as a photocatalyst in decolorization naphthol blue black (NBB) dye under ultraviolet irradiation. The was produced using iron sand source hematite with addition 15 % w/w carbon derived from waste coffee grounds hydrothermal method. as-prepared materials were characterized by X-R...

The novel ultrasound-assisted co-precipitation method was successfully applied for the synthesis of NiFe2O4 catalyst, which offered advantages lower particle size and better crystalline structure without affecting phase planes. Furthermore, efficacy synthesized catalysts evaluated using catalytic degradation Chrysoidine R dye. study designed to evaluate effect different parameters, such as pH, ...

CdO-ZnO nanocomposites were synthesized using a simple solution approach, and several characterization approaches used to examine the morphological, structural, phase, vibrational, optical, compositional properties of these nanocomposites. The FESEM study revealed development aggregates ranging in size from 250 nm 500 nm. These composed various nanoparticle shapes sizes. XRD investigation hexag...

In this study, titanium dioxide (TiO2) nanoparticles incorporated with cement were synthesis by a simple casting method as function concentration of TiO2 (0.2, 0.4, 0.8, 1, and 2 wt%). The prepared samples characterized using the technique Field Emission Scanning Electron Microscope (FESEM) UV-Visible spectrophotometer, which was used to measure adsorption spectra. observed photocatalytic effic...

A cross-sectional study was conducted to detect the presence of Salmonella spp., Candida albicans, Aspergillus spp., and antimicrobial residues in raw milk (n = 120) and processed cow milk (n = 20) from smallholder dairy farms from three sites in Zimbabwe. Culture and isolation of Salmonella spp., C. albicans, and Aspergillus spp. were performed using selective media, while antimicrobial residu...

Inadequate nutrition complicates the clinical course of critically ill patients, and many of these patients develop pulmonary edema. However, little is known about the effect of malnutrition on the mechanisms that resolve alveolar edema. Therefore, we studied the mechanisms responsible for the decrease in alveolar fluid clearance in rats exposed to malnutrition. Rats were allowed access to wate...
