“…It can be seen that the 2Â values, intensity and shape of the Ag diffraction peaks observed in the pattern are very similar to those recorded in the Ag standard atlas (2Â = 38.116 • , 44.277 • , 64.426 • , 77.472 • and 81.536 • ), indicating that Ag was successfully deposited on the QG surface and that Na 2 WO 4 ·2H 2 O did not influence Ag deposition in the bath solution. However, no obvious characteristic peaks corresponding to tungsten and tungsten compounds are found in the XRD pattern, probably due to the low tungsten content in the coating, which is in agreement with some reported literatures (Ye et al, 2008(Ye et al, , 2009). Tungsten cannot be alone deposited in its salt solutions due to its more negative electrode potential (known as difficultly deposited metal) but may be done when it is mixed with another metal ions (such as Ag ions) having more positive electrode potentials (known as easily deposited metal) in an aqueous solution, called as "induction co-deposition".…”

“…When the fragility problem is solved by applying uniform pressure with appropriate mechanical design, the low thermal conductivity, which hinders the heating and cooling processes should also be solved to realize a variotherm mold with shorter cycle time. Ag/W alloy possesses the lowest electrical and thermal resistivity among all the metals, high corrosion-resistance and good mechanical strength (Ye et al, 2009). It is also biocompatible and safe for fabricating medical plastic appliance, such as medical injectors.…”

“…The subsequent SiO 2 is etched away by the HF, allowing the metal deposited to displace it . This reaction is autocatalytic in that one of the reaction products, the noble metal itself, catalyzes further reductive deposition of metal ions . Scanning electron micrographs (SEM) recorded from a sample, predeposition (Si only), after 40 s and after 20 min autocatalytic metallization with Ag ( Figure A) also confirm that small Ag nuclei form on the Si crystals soon after immersion into the bath (40 s).…”

Commercially available metal inks are mainly designed for planar substrates (for example, polyethylene terephthalate foils or ceramics), and they contain hydrophobic polymer binders that fill the pores in fabrics when printed, thus resulting in hydrophobic electrodes. Here, a low-cost binder-free method for the metallization of woven and nonwoven fabrics is presented that preserves the 3D structure and hydrophilicity of the substrate. Metals such as Au, Ag, and Pt are grown autocatalytically, using metal salts, inside the fibrous network of fabrics at room temperature in a two-step process, with a water-based silicon particle ink acting as precursor. Using this method, (patterned) metallized fabrics are being enabled to be produced with low electrical resistance (less than 3.5 Ω sq −1 ). In addition to fabrics, the method is also compatible with other 3D hydrophilic substrates such as nitrocellulose membranes. The versatility of this method is demonstrated by producing coil antennas for wireless energy harvesting, Ag-Zn batteries for energy storage, electrochemical biosensors for the detection of DNA/proteins, and as a substrate for optical sensing by surface enhanced Raman spectroscopy. In the future, this method of metallization may pave the way for new classes of high-performance devices using low-cost fabrics.

Ordered Si nanowire (SiNW) arrays can be fabricated by metal-assisted chemical etching. The metal mesh films (MMFs) are extremely important for achieving a high quality of the SiNWs. We have developed a two-step chemical deposition method to obtain compact porous Ag MMFs. By the separation of the nucleation and growth stages of the metal in the two-step deposition processes, the overgrowth of the metals to form randomly aggregated irregular metal particles can be overcome. Hexagonally arranged polystyrene (PS) latex microspheres have been employed as a template for the deposition of porous Ag MMFs. The spacing of the pores in the Ag MMFs is determined by the diameter of PS microspheres, and the pore size can also be tuned by changing Ar plasma etching time. One of the main advantages of the two-step deposition method lies in that Ag MMFs can be produced with PS microspheres that are not limited to a single layer, which dramatically simplifies the tedious processes of producing a monolayered PS template. The two-step chemical deposition method shows great potential in metal-assisted chemical etching.
