Abstract Conducting metal interconnections are essential to link electronic components or multiple circuits for device fabrication. Scalable, rapid, and sustainable methods printing adherent on dielectric materials lacking, which stifles the development of new consumer devices. Here a breakthrough single‐step rapid process deposit highly conducting tracks is introduced, using an atmospheric pressure plasma jet. The deposition used rudimentary aqueous solution salts as ink, that was...
Copper-silver (Cu-Ag) bimetallics and alloys are attractive due to their enhanced performance compared parent metals in various fields including electronics, batteries, biomedicine, solar technology, energy storage, catalysis.[1] Existing methods for synthesizing Cu-Ag suffer from major drawbacks such as intense temperature pressure conditions, pre post-treatment processes, multiple time-consuming steps.[2, 3] In this work, bimetallic films were synthesized under ratios the first time using...
We demonstrate electrodeposition where the plasma acts as both an electrolyte and electrode, to deposit metallic conductive coatings. In conventional electroplating metal ions are reduced at a working electrode with applied electrochemical potential. Here RF atmospheric pressure jet (APPJ) is able induce reduction due presence of free electrons. The advantage this method demonstrated by ability conducting tracks on delicate surfaces including insulators polymers. small size gaseous nature...
Surface-enhanced Raman Spectroscopy (SERS) is a highly sensitive detection technique capable of nanomolar or lower limits for some analytes. 1-3 The key parameter control the surface nanostructure to optimise this remarkable enhancement, providing non-destructive without need chemical labelling. bottleneck wide applicability SERS as valuable analytical tool twofold: (1) rapid fabrication with required and (2) difficulty in recovering baseline before exposure re-exposure target matrix. Here...
