by research that any factors of health and care can be improved then it is.

this and to design an ultrasound-enhanced process that would lead to homochirality in the absence of glass beads‚ we employed seeding during ultrasound-enhanced deracemization. We theorized that by introducing larger seed crystals to the system after the establishment of the monodispersed sized crystals (~2 hours)‚ we would broaden the crystal size distribution and thus allow the deracemization process to resume. To test this idea we performed seeded experiments using ultrasound‚ in which we introduced
