Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

Ultrasonic Welding of Sheet Metals in the Water

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2008
The ultrasonic welding technique can be carried out in many different ways, such as in direct welding metals both quickly and easily when compared to other welding methods. This paper gives a description of an experimental study of the ultrasonic welding of aluminum and cupper under water bath. For example, the ultrasonic welding of Al (t : 0.2) /Cu (0.

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Dissimilar metal joining of aluminum to steel by ultrasonic plus resistance spot welding - Microstructure and mechanical properties

Materials & Design, 2019
A new joining method, i.e. ultrasonic plus resistance spot welding, is developed for dissimilar metal joining of aluminum alloy (Al) to steel. In this method, a thin Al insert is first joined to a steel sheet using the solid-state ultrasonic spot welding

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

Materials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...
