Micro-Abrasive Air Jet Machining Technology for Fabrication of Helical Grooves on Bovine Bone.

Biological bone screws play an important role in fixing fractures and bone defects. The machining of helical grooves on xenogenic materials is a key part of fabricating biological bone screws. The fabrication of helical grooves on bovine bone using micro-abrasive air jets was investigated in this paper.

Effect of ultrasound intervention timing on the formation mechanism and emulsifying properties of chickpea protein isolate-citrus pectin complexes.

This study systematically investigated the effects of ultrasonic treatment timing on the formation and emulsifying properties of chickpea protein isolate (CPI) and citrus pectin (CP) complexes. Results showed that introducing ultrasound during the CPI pre-treatment stage significantly enhanced the emulsifying activity and stability of the complexes. Notably, compared with the independent CPI, the emulsifying activity index of CPIU-CP soared from 0.
