Homemade electrodes: A simple process for fabricating

2017/1/16Carbon-based electrodes are easier to produce, but still require screen-printing technologies that are not always available, especially out in the field where portable microchip electrophoresis devices could prove really beneficial.

Inkjet

Polyacrylamide-coated, carbon nanotube (PA/CNT) electrodes were prepared by an inkjet printing process and used to measure pyocyanin and uric acid in a wound fluid simulant at 37 C. These two molecules are potential indicators of infection, and therefore their detection could prove useful for monitoring wound healing. Pyocyanin is a marker for the common wound bacterium Pseudomonas

The use of carbon aerogel electrodes for environmental

1996/10/1Aqueous solutions with various anions and canons are passed through a stack of carbon aerogel electrodes, each having a very high specific surface area (400 to 1100 m{sup 2}/g). After polarization, non-reducible and non-oxidizable ions are removed from the electrolyte by the imposed electric field and held in electric double layers formed at the surfaces of electrodes.

Carbon nanotube

2020/3/31Flexible supercapacitors (SCs) have attracted increasing attention as the power supply unit for portable/wearable electronics. Carbon nanotubes (CNTs) are promising candidate materials for flexible SC electrodes because of their outstanding mechanical property, high electrical conductivity, large surface area, and functionability. CNTs can assemble into various macroscopic materials with

Gas diffusion electrodes (GDEs) for electrochemical

Gas diffusion electrodes (GDEs) maintain a high gas concentration in the vicinity of the catalyst and improve mass transport, thereby resulting in current densities higher by orders of magnitude. However, gaseous feeds cause changes to the GDE environment, and specific features are required to efficiently tune the product selectivity and improve reaction stability.
