摘要:
A biofuel can include a diesel fuel, a plant oil, an alcohol viscosity reducer that is either a mixture of a butanol and a C1-C3 alcohol or solely butanol, and a surfactant present at no more than about 1.0% v/v. The biofuel exists as a clear, stable microemulsion at from about −10° C. to about 70° C. with the cloud point and pour point lower than −10° C.
摘要:
The present invention is a solution or colloid of fullerene, SWNTs, or graphene in cyclic terpenes, lactones, terpene-alcohol, fatty-acid alcohols, and lactones following ultrasonication and ultracentrifugation processing, for oil-energy, biological, electrical-thermal applications.The compositions are useful as fuel/oil/grease/gels (synthetic included), oil/fuel/additives/propellants, identification dyes, and heat-transfer fluids. Other functions are phase-change fluids for solar energy power plants, antifreeze, electronic dyes, electrolytic fluid/solvent, electrically-thermally conductive material for electrochemical, dielectric, filler/adhesive for semiconductor, eletro-optical, and liquid crystal substrates/coatings for touch sensitive transmissive or reflective displays.When combined with gelatin the formulations can function as dichroic-optical coatings for thin-films/waveguides/holograms. Such formulations may also be used as photovoltaic paint, electrorheological, thermophoretic-thermodiffusion, electrohydrodynamics, electric propulsion, laser enhancement, plasma jets, and magnetohydrodynamics. Energy use includes high-temperature superconductivity, or hydrogen storage using carbon, alumina, or silica supported Pd, Pt, or Zn catalysts. Biological applications include anticancer, antiviral, antifungal, drug delivery, skin permeable agents, and lubricant use.

摘要:
Disclosed is a method of monitoring and optimizing the concentration of a denaturant composition in a fuel ethanol. The method includes adding a known amount of the denaturant composition to the fuel ethanol to create a treated fuel ethanol. A measured spectroscopic absorbance or transmittance signal provides information for determining the concentration of the denaturant composition in the fuel ethanol. A component in the denaturant composition is capable of providing the spectroscopic absorbance or transmittance signal or capable of being chemically derivatized to provide a spectroscopic absorbance or transmittance signal. Based upon the measured spectroscopic absorbance or transmittance signal, the concentration of the additive composition in the fuel ethanol may be adjusted.
