Communication links operating at terahertz frequencies are envisioned to provide a revolutionary enhancement of data transmission. As fundamental building blocks, waveguides play an indispensable role in future networks, not only transporting streams with unprecedented rates, but also serving as versatile platform for signal processing. Among various waveguides, metal-wire have attracted partic...

Endoscopic ultrasound (EUS)-guided biliary access is performed when standard endoscopic retrograde cholangiopancreatography (ERCP) techniques fail and for inaccessible papillae [1]. EUS rendezvous requires passage of the guide wire into the duodenum, with subsequent removal of the echoendoscope and insertion of a second endoscope to grasp the distal end of the wire. During echoendoscope withdra...

Surfacing is a technological procedure of applying a layer of filler material to a surface of another material, i.e. a product. By surfacing, it is possible to improve chemical, mechanical, and physical properties of the parent metal, and, consequently, those of the product surfaced. Surfacing may be applied to worn surfaces as well as to new products. A surfacing weld may have the same, simila...

In this paper, the authors introduce reader to state of art Metal Wire Additive Manufacturing (MWAM) and provide a comparison between Arc (WAAM), Laser (WLAM), Hybrid Deposition (LAHWD) based on their characteristics potential future applications, since MWAM is expected have promising in various areas, such as aerospace, automotive, biomedical, energy fields. A detailed discussion benefits draw...

We describe a new strategy for the in situ growth of molecular wires predicated on the synthesis of a trifunctional "primed" contact formed from metal-carbon multiple bonds. The ruthenium-carbon pi bond provides structural stability to the molecular linkages under ambient conditions, and density functional calculations indicate the formation of an efficient conduit for charge carriers to pass b...
