Summary: Induction heating has been used for various purposes, but its potential in materials synthesis has not been extensively studied. This study demonstrates the synthesis of core-shell nanoparticles using magnetic induction heating. The nanoparticles synthesized using this approach have a higher amount of molybdenum on the surface compared to those synthesized using conventional heating. The molybdenum shell can be transformed into the Mo2C phase and the resulting nanoparticles show catalytic activity for propane dry reforming under induction heating.

Summary: The Fe3+-NTA/H2O2 process showed high efficiency in degrading TCE in groundwater, surpassing other Fe3+-chelate/H2O2 processes. The degradation was attributed to the hydroxyl radical, with formic acid and chloride ion identified as by-products. Fe3+-NTA/H2O2 consumed significantly less H2O2 compared to iron mineral-catalyzed Fenton processes and the buffering capacity of bicarbonate anions in groundwater positively influenced TCE degradation.

Summary: This study successfully achieved controllable active site construction and crystal structure regulation in heterogeneous photo-Fenton processes by introducing abundant oxygen vacancies and well-dispersed interfacial iron sites. It was found that the synergistic effects between oxygen vacancies and iron species were crucial for the superior performance. Instead of modulating the valence band, the involvement of oxygen vacancies and iron species modified the conduction band of BiOCl, promoting the migration of photogenerated electrons and accelerating the redox cycling, resulting in enhanced activation of H2O2.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
