Three-dimensional Li ion microbatteries are known for their high surface area which leads to high current and capacity compared to traditional planar batteries. This paper describes economical approaches to prepare half 3D microbatteries based on silicon microchannel plates (MCP). The high aspect ratio silicon MCP is formed by electrochemical etching and a nickel layer is coated onto the silico...

Self-assembled monolayer (SAM) with tunable surface chemistry and smooth surface provides an approach to adhesion improvement and suppressing deleterious chemical interactions. Here, we demonstrate the SAM comprising of designed and synthesized 6-(3-triethoxysilylpropyl)amino-1,3,5-triazine-2,4-dithiol molecule, which can enhance interfacial adhesion to inhibit copper diffusion used in device m...

Deposition of a coating on rough surfaces faces unique challenges due to the complexity substrate morphology. In present research, electroless deposition Ni-P was successfully deposited diamond particles. Microtomography conducted study mechanisms. It revealed that coverage rate particles affected by synergistic action time, morphology, and hypophosphite concentration. The best achieved in solu...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...

Nickel-coated carbon fibre (NiCCF) is an important composite material, which finds numerous engineering applications, primarily within: computer, telecommunication, automotive and military industries. In general, NiCCF can be produced by one of the three methods, namely: chemical vapour deposition (CVD), electroless, and electrochemical (galvanic) deposition of Ni on a carbon fibre tow material...

Electroless deposition of gold in monolayer amounts on hydrogen terminated Si(1 1 1) was studied by a variety of structure sensitive techniques. Rutherford back scattering data revealed a linear relationship between the Au coverage and the concentration of the Au solution used for deposition. Atomic force microscopy and surface X-ray diffraction studies indicated cluster formation, with the Au(...

Today the tool industry on a worldwide basis uses hard, wear-resistant, and low-friction coatings produced by different processes such as electrochemical or electroless methods, spray technologies, thermochemical, chemical-vapor deposition (CVD), and physical vapor deposition (PVD). In the current work, two different coatings, nitrocarburized (CN) and titanium carbonitride (TiCN) on M2-grade to...

Abstract Gold metallization of 3D printed polymer structures was conducted by a supercritical carbon dioxide (sc-CO 2 ) assisted electroless plating process. Precursor the Pd catalyst utilized in this study palladium bis-hexafluoroacetylacetonate for high solubility sc-CO . A Ni–P layer first formed on catalyzed structure as sacrificial sequential gold deposition. Electrical resistance metalliz...
