摘要： A general approach is provided for producing devices that absorb optical photons (visible to near IR) and performs charge separation with a useful voltage between holes and electrons. These holes and electrons may be collected in electrodes for performing useful work outside the device. The described technology is generally based upon rectification of plasmons (collective electric excitations) generated by absorbing light with tuned metallic antennas. According to some embodiments, the present invention provides a spatial array of nanoscale conductors forming an optical rectenna that responds to an incident light source and generates a current offset that may be rectified by a rectification-inducing material. The present inventors foresee an extensive use of these optical rectennas as photovoltaic devices, as well as a wide interest in diverse fundamental research and applied technologies.

摘要： According to some embodiments, the present invention provides a method for attaining short carbon nanotubes utilizing electron beam irradiation, for example, of a carbon nanotube sample. The sample may be pretreated, for example by oxonation. The pretreatment may introduce defects to the sidewalls of the nanotubes. The method is shown to produces nanotubes with a distribution of lengths, with the majority of lengths shorter than 100 tun. Further, the median length of the nanotubes is between about 20 nm and about 100 nm.

摘要： Energy is stored by injecting fluid into a hydraulic fracture in the earth and producing the fluid hack while recovering power. The method is particularly adapted to storage of large amounts of energy such as in grid-scale electric energy systems. The hydraulic fracture may be formed and treated with resin so as to limit fluid loss and to increase propagation pressure.
