Summary: This study explores the catalytic effects of heavy metals on the pyrolysis of waste polyester textiles (WPTs) and the adsorption behaviors of the pyrolysis products for Cr(VI). The findings indicate that metal ions catalyze the pyrolysis process by reducing the temperature of WPTs decomposition. The activated carbons derived from WPTs exhibit a large specific surface area and acidic functional groups on their surface, which contribute to the adsorption of Cr(VI). The adsorption capacity varies among different activated carbons, and the adsorption mechanism involves pore filling, electrostatic effect, reduction reaction, and complexation.

Summary: This study investigates the relationship between the process conditions and properties of activated carbons derived from the chemical activation of biomass in a bed of molten salts. The presence of molten salts enhances the formation of micropores and mesopores in the activated carbons. Optimum structural properties and high adsorption capacities were achieved at specific process conditions. Further development of this technology may lead to efficient production of bio-based activated carbons.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

Summary: This study aims to develop a nano-biofungicide comprising of volatile essential oil molecules to enhance its efficacy in the field of agriculture through easily scalable green synthesis technique. The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
