Experimental Investigation of Surface Color Changes in Vacuum Evaporation Process for Gold-like Stainless Steel

MATEC Web of Conferences, 2016
In order to reduce the environmental pollution caused by the three wastes during the process of electroplating of gold-like film on stainless steel, in this paper, the "vacuum evaporation and annealing" composite technologies were adopted to evaporate ...

Hollow Waveguide Arrays as Quarter- and Half-Wave Plates

IEEE Photonics Journal, 2022
We present hollow waveguide arrays acting like quarter- and half-wave plates. Approximately 2000 × 2500 individual rectangular hollow waveguides filled with air and surrounded by a gold cladding form the basis of the wave plates.

A tassel-type multilayer flexible probe for invasive neural recording

Chip, 2022
Invasive neural probes are one of the most critical components in the intracortical neural signal recording system. However, they can cause brain damage and tissue response during and after implantation.

Seedless electroplating on patterned silicon [PDF]

, 2006
Nickel thin films have been electrodeposited without the use of an additional\ud seed layer, on highly doped silicon wafers. These substrates conduct\ud sufficiently well to allow deposition using a peripherical electrical contact on\ud the wafer.

SRRs Embedded with MEMS Cantilevers to Enable Electrostatic Tuning of the Resonant Frequency [PDF]

, 2011
A microelectromechanical systems (MEMS) cantilever array was monolithically fabricated in the gap region of a split ring resonator (SRR) to enable electrostatic tuning of the resonant frequency. The design consisted of two concentric SRRs each with a set

Electroplating of Multiple Materials in Parallel Using Patterned Gels with Applications in Electrochemical Sensing

Sensors, 2020
Electrodeposition is a versatile technique for the fabrication of electrodes in micro-electroanalytical devices. Conductive but low-cost materials, such as copper, can be coated with functional yet higher-cost materials such as gold or silver using ...

The Application of Tantalum Target Substrate for Production Process of 64Cu

Journal of Isotopes, 2021
In order to obtain the appropriate target backing material for 64Cu production which will meet radiolabeling requirements, and to reduce the content of stable copper impurity generated from copper target substrate in the final 64Cu product, tantalum is ...

Cyanide-Free Gold Electroplating with 2-Hydroxyphosphonoacetic Acid (HPAA) as Complexing Agent: Experimental Investigation and Theoretical Simulation

Crystals
A novel cyanide-free gold electroplating bath was developed with 2-hydroxyphosphonoacetic acid (HPAA) as the core complexing agent in this work. Scanning electron microscopy (SEM) observations demonstrate that the obtained gold electrodeposits possess a ...
