Abstract: Reflectin proteins are proteins derived from cephalopods (certain species of squid) which have unusual optical properties. Disclosed herein are thin films of reflectin proteins which can be tuned to reflect infrared light. Advantageously, the films can be tuned dynamically over short time scales, to reflect at different wavelengths. Disclosed herein are novel infrared-reflective coatings, methods of making such coatings, and infrared-reflective objects such as textiles, building materials, and camouflage materials.

Abstract: The disclosed subject matter provides a techniques for precisely and/or functionally cutting carbon nanotubes, e.g., single walled carbon nanotubes (“SWNTs”) and integrating a single nucleic acid molecule (e.g., a DNA molecule) into a gap formed into the carbon nanotubes. In one aspect, a method of fabricating a molecular electronic device includes disposing a SWNT on a base layer, forming a gap in the SWNT using a lithographic process, and disposing a single DNA strand across the gap so that each end of the nucleic acid contacts a gap termini. The disclosed subject matter also provides techniques for measuring the electrical properties (charge transport) of a DNA molecule which is integrated into an SWNT. Furthermore, a molecular electronic device including an SWNT with an integrated nucleic acid molecule is disclosed.

Abstract: A laminated graphene device is demonstrated as a cathode. In one example the devices include organic photovoltaic devices. The measured properties demonstrate work-function matching via contact doping. Devices and method shown also provide increased power conversion efficiency due to transparency. These findings indicate that flexible, light-weight all carbon devices, such as solar cells, can be constructed using graphene as the cathode material.
