That's just the intro:"a hybrid silica sol-gel material&a nanoscale self-assembled monolayer of octylphosphonic acid"

The bilayer structure blocks the injection of electrons into the sol-gel material, providing low leakage current, high breakdown strength and high energy extraction efficiency. Devices made from the material could surpass traditional electrolytic capacitors for applications in electromagnetic propulsion, electric vehicles and defibrillators. "Sol-gels with organic groups are well known and fatty acids such as phosphonic acids are well known," said Joseph Perry, a professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology. "But to the best of our knowledge, this is the first time these two types of materials have been combined into high-density energy storage devices." The need for efficient, high-performance materials for electrical energy storage has been growing along with the demand for electrical energy in mobile applications. Dielectr...
