  • Disinfection is a critical step in sewage treatment to eliminate pathogens before the treated water is released or reused. Common disinfectants include chlorine, ozone, and ultraviolet (UV) light. Chlorine is widely used due to its effectiveness and cost-efficiency, although it can form harmful byproducts. Ozone is another powerful disinfectant that breaks down organic pollutants without leaving harmful residues. UV treatment, while chemical-free, requires substantial energy and infrastructure but is increasingly popular for its safety and efficacy.


  • The handbook emphasizes the importance of accurate chemical analysis methods to determine the composition of plastic and polymer additives. Given the complex nature of these materials, traditional analytical techniques such as gravimetry and titration often fall short. Instead, advanced methods like gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and Fourier-transform infrared spectroscopy (FTIR) have become standard tools in the analytical laboratory. These techniques allow for the precise identification and quantification of both organic and inorganic additives in diverse plastic matrices.


  • As the world grapples with issues such as antibiotic resistance and the need for antiviral therapies in the wake of global pandemics, research into new APIs remains a priority. Collaborative efforts between academia, industry, and governments are crucial in fostering innovation and addressing unmet medical needs.


  • One of the fundamental aspects of cerebrovital is nutrition. The brain, which weighs approximately 2% of the body’s total weight, demands around 20% of our daily energy intake. Consuming a diet rich in antioxidants, healthy fats, vitamins, and minerals is essential for maintaining brain function. Foods such as fatty fish, blue fruits, leafy greens, and nuts provide critical nutrients like omega-3 fatty acids, vitamins C and E, and magnesium, all of which support neuronal health and cognitive performance. Furthermore, a balanced diet helps to reduce the risk of chronic diseases, promoting long-term brain vitality.
