This invention provides a method for synthesizing a novel hydrogel that can switch its wettability and absorption for polar liquids and maintain its non-polar liquid repellency while requiring minimal heat input.  The invention enables a separation method has the potential to reduce energy costs for some industrial processes and has been employed to separate immiscible polar-non-polar liquid mixtures (water and oil) and a completely miscible liquid mixture (ethanol and heptane) at room temperature.

This invention provides an improved method for producing a novel interfacing capillary device that is less costly and more durable than existing sheathless devices.  This simplified production method does not require sample dilution, etching, or precision hand tools, and is automated and reproducible.  

The Surface Modified Ceramic Filter (SMCF) provides an inexpensive gravity filtration device for the removal of inorganic chemicals, organic chemicals, and pathogens from water. The surface modification is easily incorporated into traditional ceramic production methods, making this filter ideal for both industrial mass-production and remote operations in developing countries.
