Abstract: Self-suspending proppants including proppant particles coated with a CO2-philic coating are provided. The CO2-philic coating may be lightly crosslinked and may have a physical structure that constrains CO2 molecules. Methods of making self-suspending proppants may include coating a proppant particle with a polymerizable precursor material of a CO2-philic material and polymerizing the polymerizable precursor material to form a self-suspending proppant are also provided. Additionally, hydraulic fracturing fluids that may include a CO2-based fluid and the self-suspending proppants and methods of treating subterranean formations by contacting a subterranean formation with hydraulic fracturing fluid and propagating at least one subterranean fracture are provided.

Abstract: An electrically tunable terahertz two-path plasmonic interferometer with an integrated detection element can down convert a terahertz field to a rectified DC signal. The integrated detector utilizes a resonant plasmonic homodyne mixing mechanism that measures the component of the plasma waves in-phase with an excitation field that functions as the local oscillator in the mixer. The plasmonic interferometer comprises two independently tuned electrical paths. The plasmonic interferometer enables a spectrometer-on-a-chip where the tuning of electrical path length plays an analogous role to that of physical path length in macroscopic Fourier transform interferometers.

Abstract: A vehicle track including a soft porous material and a vehicle which rides on the track by skiing cm the soft porous material. The vehicle has a large ski surface that rides on the soft porous material, supporting the weight of the vehicle at high speeds. Air within the soft porous material supplies most of the lift needed to support the train, Qniy a small amount of the support is provided by the structure of the porous material itself when the vehicle is in motion. As a result, the friction between the soft porous material and the ski surface may also be exceedingly small. To increase the amount of lift provided by the soft porous material it can be contained within a channel having impermeable sides and bottom. If the ski surface is substantially the same width as the channel, the impermeable sides prevent the air from escaping on either side of die ski surface. Accordingly, the trapped air contributes to greatly enhanced lift force.
