Abstract: A process for carbon capture and sequestration by injection of liquefied biomass in a subsurface formation having a porous medium. A carbon-containing biomass is transformed into a liquid bio-oil. A liquid bio-oil injection rate is determined based on viscosity of the liquid bio-oil, the in-situ formation pressure, the reservoir transmissibility of the subsurface formation, and/or the mobility of the in-situ reservoir fluids. The liquid bio-oil is injected into the subsurface formation via a wellbore in the subsurface formation at an injection pressure sufficient to cause fracturing of a portion of the subsurface formation proximate the wellbore, thereby sequestering carbon in the subsurface formation.

Abstract: A double network hydrogel including a polymer (A) having a persistence length between 10 and 1000 nm; a flexible polymer (B), wherein the persistence length is measured according to single molecule force microscopy measurement, wherein polymer (B) has an extended coil conformation at a first condition and a collapsed globular conformation at a second condition. Polymer (A) preferably is a polyisocyanate, while polymer (B) is a crosslinked flexible polymer like for example PNIPAM. A method for making a double network hydrogel.
