Color and COD Removal from Textile Effluent by Advanced Oxidation Processes (ozonation)

Wasit Journal of Engineering Sciences
Using an ozone reactor, this work looks at how well ozonation removes turbidity, COD, and methylene blue dyes from polluted water. The main goals were to assess ozonation's efficacy in degrading methylene blue dyes, lowering COD, and clearing turbidity,

Formation and estimated cytotoxicity of trihalomethanes and haloacetic acids during ozonation of nonylphenol in bromide-containing water after chlorination process: Impact of ozonation initial pH

Toxicology Reports
The presence of nonylphenol (NP) in bromide-containing water contributed to the formation of regulated disinfection by-products (DBPs): trihalomethanes-4 (THM4) and haloacetic acids-5 (HAA5).

Catalytic ozonation mechanism over M1-N3C1 active sites

Nature Communications, 2023
The structure-activity relationship in catalytic ozonation remains unclear, hindering the understanding of activity origins. Here, we report activity trends in catalytic ozonation using a series of single-atom catalysts with well-defined M1-N3C1 (M ...

OZONE GENERATOR AND OZONE GENERATION

Journal of Amasya University the Institute of Sciences and Technology, 2021
Because ozone is a very active oxidizing agent and powerful antimicrobial property, it has found use in many areas. It has long been used in dentistry, in medical laboratories, in cleaning up chemical waste mixed with hospital sewage, in extending the shelf life of food through ozonation, in cleaning urban drinking water, in raising pools and fish ...

Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

Advanced Functional Materials, EarlyView.
Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection
