Redox cycling in nanoporous electrochemical devices.

Nanoscale redox cycling is a powerful technique for detecting electrochemically active molecules, based on fast repetitive oxidation and reduction reactions. An ideal implementation of redox cycling sensors can be realized by nanoporous dual-electrode systems in easily accessible and scalable geometries. Here, we introduce a multi-electrode array device with highly efficient nanoporous redox cy...

Electrochemical tuning of the optical properties of nanoporous gold

Using optical in-situ measurements in an electrochemical environment, we study the electrochemical tuning of the transmission spectrum of films from the nanoporous gold (NPG) based optical metamaterial, including the effect of the ligament size. The long wavelength part of the transmission spectrum around 800 nm can be reversibly tuned via the applied electrode potential. The NPG behaves as dil...

The Electrochemical Behavior of AISI 321 Stainless Steel in Alkaline Media

In this paper, the electrochemical behaviour of passive films formed on AISI 321 stainless steel (AISI 321) immersed in 0.1 M NaOH + 0.1 M KOH solution was evaluated by different electrochemical techniques. For this purpose, passive films were formed at open circuit potential for 1 to 12 hours and then electrochemical measurements were done. The polarization curves suggested that AISI 321 showe...

Electrochemical Synthesis of 5-Aminosalicylic Acid from 5- Nitrosalicylic Acid in Alkaline Media

5-Aminosalicylic acid (5-ASA) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-NSA) in acidic media. In this work, electrolytic reduction of 5-NSA in alkaline media is presented. Reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the pH for isolation of product are investigated. The yiel...
