摘要： A hydrophobic biofilm membrane modified with a spiropolyurethane may be used for desalination of salt water to fresh water. The spiropolyurethane component of the membrane can produce a hydrophobic spin membrane boundary which attracts saline water, and where the hydrophobic spin membrane boundary can comprise a hinge-like motion for capture of salt molecules via a loose pore-gate spongy membrane surface texture while allowing desalinated water to flow through the porous membrane. The membrane is useful in both reverse osmosis (RO) and membrane distillation (MD) separations, including the desalination.

摘要： A nitrogen activator additive to stabilize nitrogen fertilizer, where the activator is coated onto the nitrogen fertilizer, is provided. The nitrogen activator additive contains the novel compound ABT-PNB, a potassium compound, and chitosan, and provides controlled release of the nitrogen fertilizer which fertilizes crops using reduced levels of the nitrogen fertilizer and reduces the release of greenhouse gasses. Urea is an exemplary nitrogen fertilizer that can be used in this regard.
