Summary: We synthesized magnetic IONP/polymer nanocomposites (MNCs) by embedding IONPs in a poly(L-lactic acid) (PLA) matrix via nanoemulsion. The MNCs showed enhanced heating efficiency with over two-fold increase compared to nonembedded bare IONPs. In addition, the MNCs exhibited good colloidal stability under physiological conditions and maintained their heating efficiency during 48 h of incubation in cell culture medium.

Summary: Uniform-sized iron oxide nanoparticles were encapsulated inside a silica shell using the reverse microemulsion technique, then transformed into iron nitride through thermal treatment under NH3. The resulting core/shell nanostructures exhibited high uniformity in particle-size distribution. The acid-resistant properties of the iron nitride at silica core/shell nanostructures were significantly higher than the starting iron oxide at silica.

Summary: Dolomite@Al2O3 spherical particles with core-shell structure were fabricated by wrapping corundum powders on the surface of dolomite powders. The evolution of phases and microstructure were studied at different firing temperatures. The results showed that the dolomite decomposed into MgO and CaO, which diffused into the shell of the particle, forming a hollow structure. Moreover, the MgO and CaO reacted with corundum to generate spinel and calcium hexaaluminate, improving the properties of refractories. Experimental results demonstrated that the introduction of dolomite@Al2O3 spherical particles significantly enhanced the mechanical and refractory properties.

Summary: A simple one-pot method was proposed to synthesize Sb@C enantioseparation material with a controllable spherical core-shell structure. The formation mechanism of the core-shell structure was clarified. The capping of tartaric acid enantiomer on the Sb-S substance and the possible separation mechanism by hydrogen bonding based on sterical matching were verified. The structure and enantioseparation capacity of the Sb@C materials can be controlled by adjusting the ratio of Sb/S. This work presents a feasible and relatively universal strategy to design enantioseparation materials with potential application.

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.

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.
