Summary: The synthesis of nano-sized particles using a swirling vortex flow reactor involves controlled mass transfer through turbulent shear. Turbulence characteristics impact the particle morphology, chemical reactions, and mass transfer performance, with the application of ultrasound further enhancing mass transfer by intensifying local turbulent shear. The correlation between mass transfer and turbulence shear in the synthesis process of aggregated nano-particles in swirling vortex reactor using ultrasound has been clearly indicated through numerical simulations and experiments.

Summary: In this study, a facile and large-scale synthesis of high-concentration 1T-TMDs using an ionic liquid assisted hydrothermal strategy was reported. It was found that the ionic liquid adsorbs on the surface of 1T-MoS2, inducing the formation of 1T-MoS2 through steric hindrance, pi-pi stacking, and hydrogen bonds. The obtained MoS2-IL showed high stability for 180 days at room temperature and exhibited excellent HER performance in acid conditions.

Summary: Phase pure lithium trivanadate (LiV3O8) was synthesized by an ultrasound-assisted rheological phase reaction method for aqueous supercapacitor applications. The effects of ultrasound and calcination on the structural and morphological features of the synthesized samples were characterized. The sample synthesized with 10 hours of ultrasound exposure showed improved lithium (Li+) ion movement and enhanced electrochemical performance.

Summary: The Tsuji-Trost reaction of cyclopentenyl carbonates was investigated for the stereoconvergent synthesis of cyclopentenyl nucleosides. Changes in catalyst amount were found to selectively lead to the synthesis of cis configured cyclopentenyl N9-linked purine nucleosides, regardless of the relative configuration of the starting substrates. DFT studies provided insights into the low activation energy associated with the crucial inversion step.

Summary: In this study, LaMnO3 perovskite catalyst was synthesized using salt assisted combustion synthesis to control agglomeration and enhance oxygen defects, thereby improving electrochemical properties. LaMnO3-SA showed superior characteristics in oxygen electrocatalysis, displaying enhanced bifunctionality towards oxygen reduction reaction and oxygen evolution reaction. Through the introduction of an inert salt during synthesis, active sites accessible for oxygen electrocatalysis in solution combustion synthesis can be enhanced.

Summary: Optimizing the adsorption free energy and promoting the active phase transition are significant for enhancing the oxygen evolution reaction (OER) activity. This study successfully achieved these goals by modulating the electronic structure and crystal configuration, as well as introducing dislocations through the molten salt with the bound water method. The resulting dislocation layered double hydroxides (D-NiFe LDH) exhibited outstanding OER activity and stability.
