We describe a simple process for the fabrication of ultrathin, transparent, optically homogeneous, electrically conducting films of pure single-walled carbon nanotubes and the transfer of those films to various substrates. For equivalent sheet resistance, the films exhibit optical transmittance comparable to that of commercial indium tin oxide in the(More)
An electrochromic material is one where a reversible color change takes place upon reduction (gain of electrons) or oxidation (loss of electrons), on passage of electrical current after the application of an appropriate electrode potential. In this review, the general field of electrochromism is introduced, with coverage of the types, applications, and(More)
A review of electrochromic (EC) polymers and their applications in absorption/transmission, reflective, and patterned electrochromic devices (ECDs) is presented. Fundamental properties of EC materials such as optical contrast, coloration efficiency, switching speed, and stability are described along with the commonly used characterization methods. The(More)
The development of invasive, rehabilitative neuroprosthetics for humans requires reliable neural probes that are capable of recording large ensembles of neurons for a long period of time. Recent advances in the development of neuroprosthetics in animals and humans have shown that communication and control can be directly derived from the central nervous(More)
In this work, we develop an experimental testbed that couples biotic and abiotic metrics for studying, quantifying and predicting the effects of chronic electrode implantation on neural electrode performance. The rationale is based on the observation that long-term functionality is the outcome of the interactions between the dynamics of the neuronal(More)
b S Supporting Information ' INTRODUCTION Conjugated polymers have received a great deal of attention because of their applications in photovoltaic devices, light-emitting diodes (LEDs), field-effect transistors (FET), and electrochromic devices. 1À5 Similarly, conjugated oligomers 6 share many of the properties of conjugated polymers with certain(More)
