Pyrolysis of a single source material leads to a nanocomposite of carbon and silica. The bulk of the silica portion is not chemically bonded to the carbon and can be chemically removed with aqueous HF or hot alkali. The resulting carbon material has a high level of surface ...

This is a modification of an earlier design which was patented by VTIP. It is a vent that can generate low pressures in the interior of buildings, and is applicable to either flat or sloping roofs. With this vent installed on the roof of a building and subject to ...

This invention is related with benign solvents to dissolve sulfonated polymers. Sulfonated polymers have been used for various application fields such as electrolysis, electrodialysis, fuel cell and reverse osmosis owing to their high ion exchange capacities, salt rejection properties, and excellent proton conductivity. Up to now, well known polar aprotic ...

This invention is related with how to find potential solvents or non-solvents for phase inversion and how to screen them out via a theoretical expectation based on experimental data (the solubility envelope of specific polymers and the solubility parameter considering Van der Waals force, dipole-dipole momentum, and hydrogen force). The ...

This invention uses structural design at the nanometer level to achieve massive enhancement of the second order non-linear susceptibility of self-assembled organic films. Susceptibility enhancements exceeding a factor of 60 have already been achieved in a simple embodiment of the invention, which already exceeds the performance of any other ...
