Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

New Model for Estimating the Volume of Martensite Transformed Using Acoustic Emission Measurements During an Induction Hardening Process

Metals
The accurate detection and quantification of martensitic transformation in steel during quenching are essential for controlling the resulting material properties. Numerous studies have investigated this phenomenon using Acoustic Emission (AE) techniques,

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry

Advanced Materials Interfaces, EarlyView.
We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

RETRACTED ARTICLE: The effects of electrochemical, acoustic and superadditive pulsed discharge technologies on quality characteristics of various types of water

Scientific Reports
This study aimed to evaluate the effect of three different techniques, namely electrochemical treatment, acoustic treatment and superadditive pulsed discharge technology, on three types of water. Electrochemical treatment technique was applied to the tap

Preliminary study of acoustic analysis for evaluating speech-aid oral prostheses: Characteristic dips in octave spectrum for comparison of nasality

Journal of the Formosan Medical Association, 2015
Acoustic analysis is often used in speech evaluation but seldom for the evaluation of oral prostheses designed for reconstruction of surgical defect.

Effects of inlet treatment location and treatment cavity depth on compressor noise [PDF]

The ability of acoustic liners to reduce compressor noise inside and in front of an inlet was studied. An axial flow research compressor and a specially designed inlet were used inside an anechoic chamber.

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Acoustic black hole immersed sonoreactor for high-efficiency cavitation treatment

Ultrasonics Sonochemistry
Developing innovative sonoreactors to enhance acoustic processing efficiency holds immense importance in the field of sonochemistry. Traditional immersed sonoreactors (TISs) mainly produce cavitation at the probe tip, with a relatively weak cavitation ...

Drop evaporation in a single-axis acoustic levitator [PDF]

A 20 kHz single-axis acoustic positioner is used to levitate aqueous-solution drops (volumes less than or approximately equal to 100 micro-liters). Drop evaporation rates are measured under ambient, isothermal conditions for different relative humidities.

Ductility Tuning via Cluster Network Characteristics of Porous Components

Advanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by
