ABSTRACT Protohistoric gold findings from the archaeological site of Roca Vecchia (Melendugno, Lecce, Italy) are analyzed involving micrography and stratified XRF analysis. This exploitation allows to get a deeper insight into ancient gold manufacturing and wear processes adopted in the Southern Italian FBA.

Soldering Si3N4 to Invar42 by a localized heating process
Abstract This study investigates the soldering process for joining silicon nitride (Si3N4), a commonly used ceramic, to Invar42, a low thermal expansion alloy. The focus lies on analyzing interfacial reactions and evaluating the bonding performance of the Si3N4—Invar42 joint.

Additive manufacturing is expanding beyond mechanical prosthetics into microelectronic implants. This work presents a diamond‐titanium hybrid that enables wireless power transfer, localized heating, and flow sensing. The use of additive manufacturing combined with the biocompatibility of the diamond‐titanium hybrid material paves the way toward new ...
