Electromagnetic Phenomena as the Principles of Material Nondestructive Evalution
Advances in Electrical and Electronic Engineering, 2004 In the paper the principles and application of nondestructive evalution by both electromagnetic acoustic transducer (EMAT) and the eddy current (EC) methods are introducted. The ultrasonic testing (UT) and the electromagnetic nondestructive testing (NDT)

Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Label‐Free SERS Fingerprinting of Neuroprotein Conformational Dynamics in Human Saliva
Advanced Materials, EarlyView.Galvanic molecular entrapment (GME) is a label‐free method for detecting and quantifying neuroprotein conformational states. This technique enables direct surface binding and in situ hotspot generation around molecules, effectively overcoming challenges related to target localization and mismatched hotspot geometries.

Imaging of Electromagnetic NDT Phenomena
, 1986 Practical solutions of the defect characterization or NDT inverse problem still continue to be sought by researchers in a variety of industries where the location and sizing of material flaws is important to successful plant operation. The exact type of ‘imaging’ which can be used to characterize defects found by electromagnetic NDT methods depends ...
