Graphene-Based Inorganic-Organic Hybrid Materials and Separation of Racemic Mixtures

A variety of inorganic-organic hybrid materials and various methods for preparing and using the same are described. The hybrid materials are graphene or graphitic materials populated with organic molecules and may have a variety of surface defects, pits or three-dimensional architecture, thereby increasing the surface area of the material. The hybrid materials may take the form of three dimensional graphene nanosheets (3D GNS). If the organic molecules are enantiospecific molecules, the hybrid materials can be used for chiral separation of racemic mixtures.

11345839 · 2022-05-31 ·

The present invention provides for an oil pad having an oil absorbing medium which is formed or compressed to a particular shape. It is intended that such oil absorbing pad can be placed over an oily spill, or in a container containing oil, whereby the formed shape optimizes oil absorption by wicking oil to the interior of the pad, being sufficient to absorb and retain large volumes of oil, or to expand as oil is absorbed to expose one or more potions of the pad to the oil volume to be absorbed. The inventive oil absorbing pad reduces waste, does not create a mess when disposing, and effortlessly absorbs oil from an oily surface.

Self-indicating colorimetric response materials for removal and sensing of toxic chemicals and narcotics

Processes, compositions, and sensors for sensing a variety of toxic chemicals based on colorimetric changes. Exemplary process for sensing a toxic chemical includes contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide or a porous mixed-metal oxide/hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent is determined to thereby detect exposure to, or the presence of, the toxic chemical or byproduct thereof.
