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)
A 'pulsar timing array' (PTA), in which observations of a large sample of pulsars spread across the celestial sphere are combined, allows investigation of 'global' phenomena such as a background of gravitational waves or instabilities in atomic timescales that produce correlated timing residuals in the pulsars of the array. The Parkes Pulsar Timing Array(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)
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)
Understanding of the effects of fundamental molecular structure on material characteristics in conducting polymers' requires the construction of materials with very well-defined physical structures.2 Efforts to prepare regioregular head-to-tail (HT) poly(3-alkylthiophene~)~ (PATS) led to the development, in our lab4 and then el~ewhere,~ of a method for the(More)
I would like to dedicate this thesis to my family and friends who have always been there with support and love – especially John and ACKNOWLEDGEMENTS I would like to thank all those who have supported me throughout my graduate career, especially Dr. Reynolds and the members of the Reynolds group who have pushed me to grow intellectually.
