Summary: An innovative one-pot electrochemical method has been studied for the synthesis of PPy-Cu composite films as the active layer of ReRAM. Cu is uniformly distributed in the films and exhibits two valence states of Cu (0) and Cu (II). The presence of Cu (II) is beneficial for maintaining stable resistive switching performance. The Pt/PPy-Cu/Pt ReRAM device shows excellent memory performance with a low threshold voltage, a long retention time, and good endurance cycles. The resistive switching mechanism is mainly dominated by the Space Charge Limited Current (SCLC) effect accompanied by Schottky emission.

Summary: Electrochromism is the ability of a material to change its optical properties or color when an external potential is applied. Conventional electrochromic materials based on inorganic materials have drawbacks including single color change, expensive materials, and slow switching speed. To overcome these challenges, conducting polymers (CPs) have emerged as a promising alternative with advantages of multicolor, fast response, low cost, easy processing, and environmental friendliness. This review introduces the current state-of-the-art development of ECDs based on three popular CPs, namely, polyaniline, polypyrrole, and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, with emphasis on their synthetic approaches and electrochromic performance.

Summary: This study employs a simple method to load a water-oxidation catalyst (Ruthenium Red) onto the surface of an Escherichia coli bacterial template. The catalyst is characterized using various methods, which show that the bacterial template remains intact after the synthesis. The catalyst is then investigated using linear sweep, cyclic, and square wave voltammetry methods, and the water-oxidation reaction is studied under electrochemical conditions. The presence of Ruthenium Red significantly enhances the activity of the water-oxidation reaction.
