Microorganisms that respire electrodes may be exploited for biotechnology applications if key pathways for extracellular electron transfer can be identified and manipulated through bioengineering. To determine whether expression of proposed Biocathode-MCL extracellular electron transfer proteins are changed by modulating electrode potential without disrupting the relative distribution of microb...

Controlling the molecular topology of electrode-catalyst interfaces is a critical factor in engineering devices with specific electron transport kinetics and catalytic efficiencies. As such, the development of rational methods for the modular construction of tailorable electrode surfaces with robust molecular wires (MWs) exhibiting well-defined molecular topologies, conductivities and morpholog...

Infrared switching electrochromic devices based on tungsten oxide" (2000). Faculty Publications from the Department of Electrical and Computer Engineering. 4. Different types of electrochromic devices for thermal emittance modulation were developed in the spectral region from mid-to far-infrared ͑2–40 ␮m͒. In all devices polycrystalline and amorphous tungsten oxide have been used as electrochromi...

Transparent conductors (TCs) are an important component of optoelectronic devices and nanoscale engineering of TCs is important for optimization of the device performance through improved light trapping. In this work, patterned periodic arrays of nanopillars and nanolines of pitch size of ~700 nm were created on fluorine-doped tin oxide (FTO) using nanoimprint lithography and reactive ion etchi...

the glucose oxidase (gox) electrochemical sensors were used to detect a little amount of glucose. in this paper, the pure platinum plate (length of 5 cm and a width of 3 mm), the ag/agcl electrode and platinum electrode (diameter of 1 mm) were applied as a working electrode (w.e), reference electrode and auxiliary electrode sequential. factors measured, glucose concentration and ph is phosphate...

All-solid-state lithium-sulfur batteries (ASSLSBs) exhibit huge potential applications in electrical energy storage systems due to their unique advantages, such as low costs, safety and high density. However, the issues facing solid-state electrolyte (SSE)/electrode interfaces, including lithium dendrite growth, poor interfacial capability large resistance, seriously hinder commercial developme...

A modified electrode was prepared by modification of the carbon paste electrode (CPE) with graphene nano-sheets. The fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (GA) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. The graphene modified CPE had a lower overvoltage and enhanced electrical current respect to...

Perfluorinated-sulfonic-acid-based ionomers (PFSAs) are still the material of choice for electrochemical energy devices such as proton-exchange membrane fuel cells or water electrolyzers. However, PFSAs show significant drawbacks ranging from a restricted temperature window operation due to insufficient thermomechanical stability, high cost, and questionable environmental properties. Recently, ...
