It has been reported that cavitation bubbles (air–liquid interface) by femtosecond laser and ultrasonic irradiations are effective for metastable phase crystallization in polymorph control. It has also been noted that cavitation bubbles are generat

With the continued adoption of passive acoustic monitoring as a tool for rapid and high-resolution ecosystem monitoring, ecologists are increasingly making use of a suite of acoustic indices to summarise the sonic environment. Though these indices ar

The growth of acetaminophen polymorphic crystals and the solution-mediated phase transition from trihydrate to form II in agarose gel were investigated. The form II crystals grown in gels, presumably because of the agarose content, dissolved less rap
