Mechanical Properties and Microstructure of Copper Alloys and Copper Alloy-Stainless Steel Laminates for Fusion Reactor High Heat Flux Applications
… overall mechanical properties of the studied bi-metallic bonded panels. Bond properties were nominally inferior to constituent bulk material properties and fracture toughness values, in particular, were quite low for all bonded laminates. Delamination near the copper alloy-stainless steel …

Ultrasonic Attenuation In As-Deposited Inconel 182 Weld Metal and Recommended Techniques for Discontinuity Evaluation.
… of full penetration welds in pressure retaining bi-metallic and tri-metallic joints involving as-deposited austenitic weld material. The weld joint design was one simulating a component on a nuclear reactor known as a safe-end-to-nozzle. Because the joint is part of a nuclear reactor, explicit …

The Formation of Metal Nanoparticle-Carbon Nanotube Composite Materials for the Non-enzymatic Detection of Glucose
… AuNPs of a face-centred cubic structure were successfully formed on the sidewalls of the fMWCNTs. The fMWCNT-Aunano(NaBH4) composite had an Au loading of 2.0% wt. and contained AuNPs with a mode diameter of 7.5 nm. The fMWCNT-Aunano(TriSodCit) composite had an Au loading of …
