Low-Frequency Acoustic Microscopy [PDF]
, 1985 Since acoustic microscopy was first invented by Quate and Lemons,1 many workers in the field have built acoustic microscopes ranging in frequency from tens of megahertz to hundreds of gigahertz, nd for a wide variety of applications in materials ...

Wideband acoustic microscopy of tissue [PDF]
The Journal of the Acoustical Society of America, 1988 A scanning acoustic microscope (SAM) has been used to measure the elastic properties of tissue with a resolution of around 8 μm (C. M. W. Daft et al., Proc. 1986 IEEE Ultrasonics Symposium, 945—948). This is achieved by broadband excitation of the acoustic lens, and the recording of an undemodulated returning signal.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
