Three-dimensional electrodes that are controllable over multiple lengthscales are very important for use in bioanalytical systems that integrate solid-phase devices with solution-phase samples. Here we present a fabrication method based on all-solution-processing and thin film wrinkling using smart polymers that is ideal for rapid prototyping of tunable three-dimensional electrodes and is exten...

In order to broaden the application range, PEEK has been modified by 1064nm-wavelength pulse laser, then deposited with Ni-P alloys electroless plating. The properties of metal layers on were characterized SEM, resistance tester and metallographic microscope, respectively. When laser energy density is relatively low (Q<60J·cm -2 ), there mainly photothermal effect surface substrate presents ...

In recent years, nanomachining has attracted increasing attention in advanced manufacturing science and technologies as a value-added processes to control material structures, components, devices, and nanoscale systems. To make sub-micro patterns on these products, micro/nanoscale single-crystal diamond cutting tools are essential. Popular non-contact methods for the macro/micro processing of d...

Carbon nanoparticles have excellent lubricating properties, however, they are less involved in metal protection. In this study, easily prepared candle soot was added to electroless nickel-phosphorus plating as a re-enforcement particle. Ball-disc friction and wear tests were conducted evaluate the wear-resistance capabilities of Ni-P coating Ni-P-CS (Candle Soot) composite coatings. The paramet...

Thin Pd–Ag layers have been successfully deposited on ceramic supports with controlled surface characteristics. The need for less fragile membranes and ease of sealing connection leads to the study metallic thin Pd-based membrane development. Metallic supported are prone intermetallic diffusion issues so an interdiffusion barrier must be introduced. However, sufficient quality direct deposition...

Brittle solder joints in Electroless Ni electroless Pd immersion Au (ENEPIG) surface finishes are one of the key re­ liability issues in electronics assembly. Previous characterization of the reflow process has indicated that interfa­ cial voids formed after solder reflow are responsible for the decreases in solder joint strength. However, the mechanisms behind the formation of these voids in t...

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...

the effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. the reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a pc1d simulation....
