Ultrasonic topic: "Sonochemistry nima?"
Sonokimyo ultratovushni kimyoviy reaktsiyalar va jarayonlarga qo'llashdir. SOnication sintez va kataliz kabi kimyoviy reaktsiyalarni kuchaytirish uchun ishlatiladi. Kuchli ultratovush to'lqinlari suyuqliklarga juftlashganda, akustik kavitatsiya hodisasi paydo bo'ladi. Ultrasonik kavitatsiya reaktivlar orasidagi massa almashinuvini yaxshilaydi, reaktsiyani tezlashtiradi va / yoki kimyoviy moddalar yo'lini o'zgartirishga imkon beradi.
Hielscher ultratovush laboratoriyasi va sanoat qurilmalari va ular ko'p sonokimyoviy jarayonlarda qanday qo'llanilishi haqida ko'proq bilib oling!

Sonication Opens New Pathways in Supramolecular Chemistry
Supramolecular chemistry depends on weak, reversible interactions: hydrogen bonding, π–π stacking, van der Waals forces, solvophobic effects and chiral recognition. These interactions allow molecules to self-organize into larger architectures such as fibers, rods, gels, aggregates and supramolecular polymers. For chemists…
