Summary: Magnetized activated carbons (MAC) prepared from rape straw powder showed high adsorption capacities for Pb(II) and Cd(II) due to surface active points, with adsorption behavior conforming to the Freundlich model and pseudo-second-order kinetic model. Thermodynamic parameters indicated spontaneous and endothermic reactions. Adjusting the pH of the solution could enhance adsorption capacity, but competitive adsorption occurred in the presence of high-valent ions. Adsorption mechanisms included electrostatic attraction, surface complexation, and co-precipitation. The MAC material showed potential for heavy metal ion removal from aqueous solutions.

Summary: Microwave biochar produced with activated carbon catalyst shows excellent potential in removing heavy metals from waste water due to its high specific surface area and adsorption capacity. The optimum pH value for heavy metal removal is between 5-6, and Pb2+ exhibits the strongest affinity. The adsorption process is mainly explained by monolayer adsorption and chemical adsorption mechanisms. Complexation with oxygen-containing functional groups and precipitation with carbonate are the predominant adsorption mechanisms.

Summary: An efficient catalyst based on solid NaOH coated with a hydrophobic layer was developed for the synthesis of 4,40-bis(2,6-di-tert-butylphenol), which is commonly used as an antioxidant in polymers, fuels, and lubricants. The catalyst's hydrophobic coating, consisting of sodium phenolate and titanate, enhanced its mechanical durability and formed catalytically active sites. Characterization techniques such as SEM-EDS, TEM, FT-IR, TLC, and HPLC were used to analyze the catalyst's properties. The catalyst showed high activity and stability in the initial stage of the synthesis, and its kinetic regularities were investigated.

Summary: This study investigates the effect of nano-dispersed silicon dioxides nanoparticles (nSiO(2)) on ferroelectric switching and phase transition properties in a ferroelectric metal-organic framework of [ND4][Zn(DCOO)(3)]. The addition of nSiO(2) was found to increase phase transition temperatures and inhibit repolarization in the ferroelectric parts. Furthermore, increasing amounts of nSiO(2) made it more difficult to obtain saturated dielectric hysteresis loops, resulting in a transformation into unsaturated ones with a higher coercive field. The presence of residual water molecules on nSiO(2) was identified as the cause for these anomalies.

Summary: Long-term reliance on fossil fuels is causing the energy crisis and environmental problems to worsen. Therefore, innovative energy-conversion technologies are needed to replace conventional fossil-based energy systems. However, the widespread use of these technologies is hindered by the use of expensive precious metals as electrode catalysts. Surface metal nitrides (SMNs) have emerged as one of the best electrode materials to replace noble metal-based electrocatalysts in the next generation of energy storage and energy-conversion devices. This paper discusses the recent advancements in the use of SMNs for electrocatalysis, including their structure and activity origins, synthesis techniques, examples of their use in various reactions, and the current challenges and future prospects.
