Ultrasonic interferometer on shear waves in liquids [PDF]
Izvestiya vysshikh uchebnykh zavedenii. Fizika, 2019 The developed ultrasonic interferometer on low-frequency shear waves in liquids is described. The problem of the piezo-quartz crystal – liquid interlayer – cladding interaction has been solved, and formulas for calculating the viscoelastic parameters of the liquid have been obtained.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Advanced Healthcare Materials, EarlyView.Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

Mode-switching: a new technique for electronically varying the agglomeration position in an acoustic particle manipulator [PDF]
, 2010 Acoustic radiation forces offer a means of manipulating particles within a fluid. Much interest in recent years has focussed on the use of radiation forces in microfluidic (or “lab on a chip”) devices.
