Abstract: An assembly and method are disclosed for generating and detecting a modulated pressure signature in a fluid transported to a subsurface injection zone. The assembly includes a pump, a pulsation dampener, and a pressure modulation device that oscillates pressure to produce a frequency-modulated signature in the fluid, resulting in an alternating current streaming potential (AC-SP) at the injection zone. The method includes recording modulated electromagnetic signals at an array of electromagnetic field receivers on a surface above the subsurface injection zone, processing the data to identify source frequency signals, and correlating these signals to image subsurface fluid or pressure distribution, enabling three-dimensional mapping of subsurface structures.

Abstract: A method is disclosed for coating and patterning hydrogels in order to modify surface properties. The method exploits the water content of the hydrogel and the hydrophobicity of the reaction solvent to create a thin oxide adhesion layer on the hydrogel surface. This oxide adhesion layer enables rapid transformation of the hydrophilic, cell non-adhesive hydrogel into either a highly hydrophobic or a cell-adhesive hydrogel by reaction with an alkylphosphonic acid or an ?,?-diphosphonoalkane, respectively. Also disclosed are coated, patterned hydrogels and constructs comprising the coated, patterned hydrogels.
