Title: The Innovative Contributions of Jeffrey J Urban
Introduction
Jeffrey J Urban is a prominent inventor based in Emeryville, CA. He holds a total of 7 patents that reflect his significant contributions to the fields of water desalination and hydrogen storage technologies. His work is characterized by innovative approaches that address critical environmental challenges.
Latest Patents
One of Urban's latest patents is titled "Systems and methods for water desalination using thermo-responsive ionic liquids regenerated by solar energy." This invention provides systems, methods, and apparatus related to water desalination. The method involves generating a diluted draw solution using forward osmosis, where wastewater is on one side of an osmotic membrane and a draw solution on the other. The draw solution consists of a mixture of water and an ionic liquid, allowing water in the wastewater to diffuse across the membrane to form the diluted draw solution. The diluted draw solution is then heated using a photonic heater to phase separate it into the ionic liquid and treated water.
Another notable patent is "Graphene oxide/metal nanocrystal multilaminates the atomic limit for safe, selective hydrogen storage." This invention describes an environmentally stable and exceptionally dense hydrogen storage solution, achieving a gravimetric capacity of 6.5 wt % and 0.105 kg H/L in the total composite. The multilaminates utilize atomically thin and gas-selective reduced graphene oxide sheets as encapsulants, significantly exceeding the 2020 DOE target metrics for fuel cell electric vehicles.
