A method of coating an antimicrobial conductive metal layer on a non-conductive surface of articles with novel chemistry and methods with just a few process steps consisting of contacting the chemistries at room temperature for short durations is disclosed. The methodology is environmentally friendly, non-toxic aqueous bath of different salt compositions for providing uniform anti-microbial metal coating on the articles. The cost-effective methodology can be used on a wide variety of non-conductive surfaces such as glass, fibers, textiles, ceramic, plastic, foam and so on.

The present disclosure relates to a method for forming a glass structure having a metallized surface portion. The method may comprise forming a structure using a flowable first material, adapted to form a glass, which includes a metal component. The structure is then treated to remove substantially all solvents and organic components contained in the first flowable material. Finally, the structure is exposed to a bath of a metal salt during which nucleation occurs and a metallized surface coating is formed on at least a portion of an outer surface of the structure.

A circuit layer is formed by drilling vias and forming channels in a circuit layer which has catalytic particles exposed on the surfaces, channels, and vias. A first flash electroless deposition is followed by application of dry film, followed by selective laser ablation of the dry film channels and vias. A second electroless solution is applied which provides additional deposition over the first flash electroless deposition but only on the vias and trace channel areas. An electrodeposition follows, using the first deposition as a cathode. The dry film is stripped and the first electroless layer is etched, leaving only depositions in the channels and vias.

Methods of treating metal nanocrystals are provided. In embodiments, such a method comprises exposing metal nanocrystals comprising a metal and characterized by at least one twinning boundary therein, to a plating solution comprising a reducing agent and coating metal cations comprising a different metal, under conditions to form a coating of the different metal on surfaces of the metal nanocrystals via electroless deposition by chemical reduction of the coating metal cations, thereby providing coated metal nanocrystals. Methods of forming bulk nanostructured metal alloys from the coated metal nanocrystals are also provided.

wherein the cloud points are determined according to European Standard EN 1890:2006, item 8.2 of German Version, with the modification that 10 wt % H.sub.2SO.sub.4 is used as solvent and that the concentration of the surfactant is 1000 mg/L.

Additive manufacturing processes, such as fused filament fabrication, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of a printed object. Conductive traces and similar features may be introduced in conjunction with fused filament fabrication processes by incorporating a metal precursor in a polymer filament having a filament body comprising a thermoplastic polymer, and forming a printed object from the polymer filament through layer-by-layer deposition, in which the metal precursor remains substantially unconverted to metal while forming the printed object. Suitable polymer filaments compatible with fused filament fabrication may comprise a thermoplastic polymer defining a filament body, and a metal precursor contacting the filament body, in which the metal precursor is activatable to form metal islands upon laser irradiation.
