Near-field acoustic imaging with a caged bubble
Nature CommunicationsBubbles are ubiquitous in many research applications ranging from ultrasound imaging and drug delivery to the understanding of volcanic eruptions and water circulation in vascular plants. From an acoustic perspective, bubbles are resonant scatterers with

Acoustic microscopy of solid materials
Metallography, 1985 Abstract Conventional ultrasonic imaging uses frequencies up to 10 MHz or perhaps a little higher. Scanning acoustic microscopy extends the frequencies used to the GHz region, with a corresponding improvement in resolution. The technique is now beginning to be applied to problems in the study of materials.

Electrolyte Design for Fast‐Charging Lithium‐Based Batteries
Advanced Materials, EarlyView.A decade of progress in fast‐charging electrolytes for lithium batteries is reviewed. Electrolyte design strategies spanning solvents, salts, additives, and advanced systems, such as localized high‐concentration electrolytes (LHCEs), are summarized. Advanced diagnostic tools for lithium plating and interphase chemistry are discussed, with perspectives ...

Scanning acoustic microscopy of polymeric materials and biological substances
Archives of Acoustics, 2015 For the last few years a new method of visualization and quantitative analysis of physico-mechanical properties and microstructure of heterogenetic media — the acoustic microscopy — has been intensively elaborated in the world.

Acoustic Microscopy for Imaging and Characterization
MRS Bulletin, 1996 Acoustic microscopy is useful for characterizing with high spatial resolution the elastic structure and properties of an object. A range of techniques is now available for doing this, which enables the user to select the method and instrument that is most appropriate for a particular requirement.

Advanced Materials, EarlyView.We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

ACOUSTIC MICROSCOPY OF ULTRASONIC ATTENUATION
Le Journal de Physique Colloques, 1983 The scanning acoustic microscope can image ultrasonic attenuation. The plastic zone at a stressed notch has been imaged in transmission with the contrast arising from dislocation damping. Contrast in reflection is also shown to be sensitive to attenuation, enabling attenuation to be detected and imaged with spatial resolution of ~2µm.
