Advances in Chemistry Research. Volume 63 considers the recent achievements in the field of biomimetic sol-gel mineralization of natural polysaccharides for obtaining biologically active silicon-containing hydrogel materials, as well as the effect of the chirality of the main classes of biomimetics on their functional properties. The effects of reaction conditions such as temperature, weight hour space velocity and catalyst modification using different types of metals on catalyst activity and selectivity are explored. Following this, a review is provided on the influence of different acid types on the reaction course and selectivity of Prins cyclization of chosen aldehydes and homoallylic alcohols. In addition, an investigation of the best methanol to olefin conversion catalyst, SAPO-34, is studied in both synthesis and metal promotion. The penultimate chapter highlights the properties of Casuarina fruit as adsorbent material for water pollutants removal. These findings are expected to shed some light on the removal performance, as well as promising applications of Casuarina fruit-based activated carbon for wastewater treatment. Lastly, nanoparticles of phthalic acid/aluminum nitrate are synthesized using a hydrothermal method, leading to a large quantity of CAU-10-H.
