Controllable synthesis of hierarchical micro/nano structured FePO4 particles under synergistic effects of ultrasound irradiation and impinging stream

Sustainable Utilization of Fe(Ⅲ) Isolated from Laterite Hydrochloric Acid Lixivium via Ultrasonic-Assisted Precipitation to Synthesize LiFePO4/C for Batteries

“…The conventional co-precipitation method is prone to introduce impurities into the cathode material owing to the high local pH, thereby adversely affecting its electrochemical performance [23]. The important role of mechanical force in the transfer of energy to chemical bonds for driving chemical reactions during manufacturing processes was only recently The important role of mechanical force in the transfer of energy to chemical bonds for driving chemical reactions during manufacturing processes was only recently recog-nized [24,25]. In 2020, Grzybowski et al reported that the growth rate of crystals can be significantly accelerated using shear stress generated by fluid dynamics through local stirring (physical effects) rather than by the surface energy effects involved in classical Ostwald ripening (chemical effects) [26].…”

Turbulence induced shear controllable synthesis of nano FePO4 irregularly-shaped particles in a counter impinging jet flow T-junction reactor assisted by ultrasound irradiation

“…For the synthesis processes of various functional micro/nano particles using chemical reactors such as mixing tanks, the hydrodynamic mixing effect plays a crucial role in adjusting the energy, heat and mass transfers in the process, consequently affecting the properties of final products [1] , [2] , [3] . At molecular scale, the selectivity of chemical reaction is significantly influenced by the mixing process, in particular the micromixing time, which is to a great extent affected by both the turbulent eddies characterized by the macromixing and mesomixing [4] , [5] . T-type impinging stream microreactor (TISR) is the simplest mixing device which can provide extremely rapid micromixing and effectively enhance the process turbulence intensification, delivering homogeneous supersaturation level before particle nucleation process and leading to the final particle products with relatively uniform properties [6] , [7] .…”
