Compositions of swellable non-toxic hydrogels and their use in conformance control are described herein. More specifically, the present invention generally relates to the hydrogels compositions that can be used to treat the oil reservoirs having high temperature and high salinity conditions. The compositions generally comprise a plurality of swellable particles having one or more crosslinkers interspersed within a polymer matrix. The compositions can also be used in biomedical, agricultural, fracking and similar applications wherein thermally-stable, nontoxic hydrogels are required.

A process of curing a photo-curable material includes dispersing a microcapsule in a material that includes a photo-initiator and a photo-curable material. The process also includes applying a stimulus to the microcapsule to trigger a chemiluminescent reaction within the microcapsule. The chemiluminescent reaction generating a photon having a wavelength within a particular emission range that is consistent with an absorption range of the photo-initiator. The photon exits the microcapsule to trigger the photo-initiator to initiate or catalyze curing of the photo-curable material.

The present invention provides an organic bioelectronic HD device system for the effective removal of protein-bound substances, comprising PEDOT:PSS, a multiwall carbon nanotube, polyethylene oxide (PEO), and (3-glycidyloxypropyl)trimethoxysilane (GOPS).

Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.
