Skin‐like ultra‐sensitive gas flow sensing based on ionically conductive organogels

InfoMat, EarlyView.
An elaborately designed gas flow sensor based on organogels was employed to precisely monitor trace gas flow disturbances. Leveraging a reversible ion‐mediated cooperative effect, the skin‐like gas flow sensor exhibited excellent sensing performance toward gas flow, featuring low operation voltage and high sensitivity.

Cardiac Histomorphometric Implications Resulting From Chronic Nandrolone Decanoate Treatment in Rats Subjected to Resistance Training

Journal of Applied Toxicology, EarlyView.
ABSTRACT The effects of anabolic steroid abuse on the cardiac tissue of resistance training practitioners are poorly understood. Herein, we present the histomorphometric implications of resistance training in rats treated with nandrolone decanoate, an androgenic anabolic steroid. Eighteen‐week‐old male Wistar rats (N = 32) were divided into two groups (

Spectral theory of unidirectional transducers

Archives of Acoustics, 2014
A spectral theory of single-phase unidirectional transducers of the surface acoustic waves is presented. It helps to evaluate the stop-band width where the directionality takes place, and allows one to optimize the transducer structure in order to ...

Microfluidic Molecular Diagnostic Chips: Functional Modules, Integration Strategies, and Emerging Applications

Small Methods, EarlyView.
This comprehensive review delivers an engineering‐centric analysis of microfluidic molecular diagnostic chips, breaking them down into foundational modules from fluid manipulation to bio‐sensing. Beyond chip design, it evaluates sample‐to‐answer integration strategies and commercial readiness levels.

Lamb wave transducers made of piezoelectric macro-fiber composite [PDF]

, 2014
During recent years, an intensive research activity concerning the application of Lamb waves (LWs) for SHM has been observed. LWs may be generated and sensed using different types of transducers, and their selection is essential for the SHM system’s ...

On an approximate method for calculating filters based on acoustic surface waves

Archives of Acoustics, 2016
The work describes an electric filter consisting of interdigital transducers deposited on piezoelectric substrate. A method has been presented for computing the transducer parameters with an assumed amplitude-frequency cha¬racteristic.

Detection of a Submillimeter Notch-Type Defect at Multiple Orientations by a Lamb Wave A₀ Mode at 550 kHz for Long-Range Structural Health Monitoring Applications

Sensors
The early detection of small cracks in large metal structures is a crucial requirement for the implementation of a structural health monitoring (SHM) system with a low transducers density.

Treatment of Canine Atopic Dermatitis: Updated Guidelines From the International Committee on Allergic Diseases of Animals (ICADA)

Veterinary Dermatology, EarlyView.
ABSTRACT Background Canine atopic dermatitis (cAD) is a genetically, aetiologically, immunologically and clinically complex disease requiring both individualised immediate and long‐term management. Objectives These updated guidelines from the International Committee on Allergic Diseases of Animals (ICADA) aim to substantially revise previous ...
