The present invention relates to modified proppants and methods of using the modified proppants that use metal ligand tracers to characterize subterranean fluid flow. The metal and ligands are best chosen to be a strongly-coordinating, chelating ligand with a functional group for the chosen flow environment.

Molecular tracers and modified proppants for monitoring underground fluid flows

Proppant compositions for use in hydraulic fracturing and methods of using same are disclosed herein. The proppant compositions include a plurality of proppant particulates and at least one particulate of the plurality of proppant particulates containing at least one tracer, wherein the at least one tracer separates from the at least one particulate located inside a fracture of a subterranean formation after a period of time.

Proppant compositions and methods of use

The present invention provides a novel solution or route for metal phosphide (MP) nanomaterials from the thermal decomposition of metal bis[bis(diisopropylphosphino)amide], M[N(PPri)], and/or single-source precursors. Synthetic routes to MPnanomaterials may be used in energy applications including batteries, semiconductors, magnets, catalyst, lasers, inks, electrocatalysts and photodiodes.

Metal phosphide nanomaterials prepared from single source metal amides

A method and precursor for making carbon fibers and the like comprising carbon black modified with at least one cyclic compound promoter. A source of the carbon black may be recycled materials such as recycled tires or recycled plastics. The carbon black is modified by attaching at least one cyclic compound promoter to the outer periphery of the carbon black.

Methods of using N-containing compounds with carbon black to replace pan and form carbon fibers

Novel complexes of various earth-abundant, inexpensive transition or main group metals that facilitate the transformation of carbon dioxide into other more useful organic products. These complexes can bind and alter the COat mild conditions of temperature and pressure, enabling, according to some embodiments, the electrochemical conversion of COinto new products.

Carbon dioxide transformation facilitated by earth abundant metals
