Summary: In this study, a sustainable precursor, raw clay (RC), was obtained from the Amazon region in Brazil and purified to form a clay-based adsorbent (CBA). The CBA was characterized using various techniques and used to remove basic yellow 2 (BY2) dye from aqueous solutions, achieving a removal rate of 98% under optimal conditions. The correlation between quantum chemical descriptors and experimental results suggests that BY2 dye is adsorbed on the CBA surface through electrostatic interactions.

Summary: The objective of this study is to investigate the use of sludge from drinking water treatment plants as an adsorbent for removing methylene blue (MB) dye from contaminated water. Chemical activation of the used sludge was performed to create new adsorbents using HCl, H2O2, and a mixture of HCl and H2O2. Various boundary conditions, such as initial dye concentration, adsorbent dosage, solution pH, contact time, and temperature, were tested to determine the optimum operational conditions. The results showed that sludge activated by a 2:1 mixture of HCl/H2O2 was the most effective adsorbent, achieving a 99.9% removal rate. The best MB adsorption results were obtained with an initial dye concentration of 50 ppm, a contact time of 90 minutes, a pH of 7, and an adsorbent dosage of 0.25 g. The Langmuir and Freundlich models fit well with the adsorption behavior of the adsorbents.

Summary: Conjugated porous polymers (CPPs) are a new family of functional porous materials with tuneable porosities and molecular architectures, showing great potentials in adsorption, light harvesting, and catalysis applications. This study describes the incorporation of strong visible-light absorbing BODIPY molecules into the skeleton of CPPs, resulting in CPPs with integrated properties of high surface area, hierarchical porous structures, and strong visible-light absorption. The obtained CPPs demonstrated relatively high adsorption capacity and high photocatalytic degradation efficiency towards organic dyes, with mechanism studies revealing the generation of singlet oxygen species as the main driving force for the dye degradation.

Summary: Poly(ε-caprolactone) (PCL) is a low-cost, biocompatible, and bioresorbable synthetic polymer widely used in biomedical applications. However, its low mechanical strength, insufficient cellular recognition sites, poor bioactivity, and hydrophobicity limit its broader use. To overcome these challenges, researchers have extensively investigated blending PCL with nature-derived polymers and incorporating nanofillers.
