Improving adhesive bonding of short carbon fiber thermoplastic composites to aluminum alloys with a hybrid laser-plasma surface modification strategy

Materials & Design
This study investigates hybrid laser–plasma surface modification strategies for metal–CFRTP (carbon-fiber-reinforced thermoplastic polymer) dissimilar joints to improve their bonding performance, in contrast to existing literature that mostly focuses on ...

Surface Oscillations in Overdense Plasmas Irradiated by Ultrashort Laser Pulses [PDF]

, 2001
The generation of electron surface oscillations in overdense plasmas irradiated at normal incidence by an intense laser pulse is investigated. Two-dimensional (2D) particle-in-cell simulations show a transition from a planar, electrostatic oscillation at

TiO2 nanotubes film/FTO glass interface: Thermal treatment effects [PDF]

Science of Sintering, 2022
Pure Ti films deposited by radio-frequency magnetron sputtering on FTO glass were anodized to fabricate TiO2 nanotubes (NTs) arrays. The TiO2 NTs/FTO samples were sintered at 450, 550 and 630°C, in ambient air.

Method for Measuring the Laser Field and the Opacity of Spectral Lines in Plasmas

Plasma, 2021
In experimental studies of laser-plasma interactions, the laser radiation can exist inside plasma regions where the electron density is below the critical density (“underdense” plasma), as well as at the surface of the critical density.

Pulse duration dependent laser-induced plasma etching of polyimide using a high repetition rate laser

Applied Surface Science Advances, 2023
Although laser ablation of polymers is well investigated the achievable surface quality of this process is limited due to laser-induced structural and morphological defects, arising surface roughness and redeposition of debris.
