Fingerprinting metal transfer from mantle [PDF]
Nature Communications, 2019 The ore-forming magmas in post-subduction copper deposits are thought to be derived from the lower crust. The Au-Te fingerprints of post-subduction magmas reveal an important role for the metasomatized sub-crustal lithospheric mantle in the formation of ...

PVA-assisted metal transfer for vertical WSe2 photodiode with asymmetric van der Waals contacts [PDF]
Nanophotonics, 2023 The vertical electronic and optoelectronic devices based on 2D materials have shown great advantages over lateral devices, such as higher current density, faster switch speed, and superior short-channel control.

Frontiers in Mechanical Engineering, 2020 Introduction. These thoughts are offered as a reminder that Tribology is not all about the normal contact of fractal surfaces, and indeed, not all about elastic contact of rubber and polymers, or even about dry contact. Machines do still contain metal surfaces sliding past each other, hopefully separated by an oil film; and sometimes, when tolerances ...

Revealing the mechanism of cold metal transfer. [PDF]
Commun EngAbstract Cold metal transfer (CMT) is a pioneering feeding system widely used in wire-arc additive manufacturing (WAAM) and welding. However, process optimisation remains challenging. Although CMT has been extensively applied in various industrial sectors, its underlying mechanism is poorly understood because of the complex physics of the ...

Numerical Analysis of Metal Transfer Process in Plasma MIG Welding
Metals, 2022 In plasma MIG welding, inert gas introduced from the torch nozzle is ionized in the upstream region of the MIG arc, which is termed “plasma”. This study aims to clarify the effect of the plasma on the metal-transfer process in the plasma MIG welding ...
