Thermoelastic Grating for Non-Destructive Testing by Laser Ultrasonics

Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023
Ultrasonic Non-Destructive Testing (NDT) uses many types of sources mostly based on piezoelectric transducers. This paper focuses on the generation and detection of acoustic waves by Laser Ultrasonics which is a wellknown non-contact inspection method. More precisely, the main goal of this work is to analyze the interaction between a flaw and Rayleigh ...

In Situ Photopolymerization of Smectic B Liquid‐Crystalline Electrolytes from Mesogenic Phosphate–Diacrylate/Ionic Liquid Complexes for High‐Performance Soft Ionic Actuators

Advanced Robotics Research, EarlyView.
A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).

In Vivo Microplastic Detection With Photoacoustic Imaging

Advanced Science, EarlyView.
ABSTRACT Microplastics are posing an escalating threat to both ecological systems and human health. Yet, current methods for investigating their bioaccumulation are highly invasive, requiring destructive analysis of ex vivo tissues via mass spectrometry, dye labelling, or Raman microspectroscopy.

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths

Advanced Science, EarlyView.
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Laser-Induced Koebner-Related Skin Reactions: A Clinical Overview

Medicina
The Koebner phenomenon (KP), also known as the isomorphic response, describes the process by which new lesions that are clinically and histologically identical to a patient’s existing skin disease develop following trauma. Many skin diseases exhibit this
