Summary: The use of TiO2 nanoparticles for photocatalysis for the degradation of organic dyes under UV light for wastewater treatment has been widely studied. However, the photocatalytic characteristics of TiO2 nanoparticles are inadequate. In this study, three types of nanoparticles (TiO2, ZrO2, and mixed-phase TiO2-ZrO2) were synthesized and their properties were examined. The results showed that the mixed-phase TiO2-ZrO2 nanoparticles exhibited higher photocatalytic activity for the degradation of Eosin Yellow under visible light compared to TiO2 and ZrO2 nanoparticles.

Summary: The study found that traditional Paraguayan foods such as meat and dairy products have high levels of saturated fatty acids, while olives and chipa mainly contain oleic acid. Some foods have high levels of trans fatty acids, and traditional Paraguayan dishes like sopa Paraguaya and empanada have a high n-6/n-3 fatty acids ratio due to the addition of soybean and corn oils in preparation. The data presented can help improve eating habits in Paraguay and address risk factors associated with poor dietary habits and chronic health issues.

Summary: This study analyzed and determined the levels of 5-hydroxymethylfurfural (HMF) and furfural (FF) in 27 honey samples from different regions in Brazil and investigated the storage conditions of these samples. The researchers used HPLC-DAD method with an internal standard to analyze the samples. Near-infrared (NIR) and middle-infrared (MIR) spectral analyses, as well as chemometric tools, were employed to study the compounds in the samples. The study found that HMF and FF contents in honey samples collected directly from beehives were low, while wildflower and soy flower honey samples met the freshness and quality criteria. Commercial honey samples showed a wide range of HMF and FF contents. FF was found to be more toxic than HMF. The NIR analysis identified higher HMF concentrations in specific wavelength regions.
