Abstract: Modified chemical structures of cardanol extracted from cashew nut shell oil, and the use of the same to prepare imidazolium ionic liquids (IILs). The IILs can be used to prepare different types of silica, magnetite and calcium carbonate nanoparticles (NPs) as multifunctional oilfield chemicals for use in various oil spill collection, de-emulsification, viscosity improvement, asphaltene dispersant, and enhanced oil recovery applications.

Abstract: The present invention discloses an electrified fiber sorbent formed from a support comprising a sorbent and a conductive material, and a manufacturing method therefor. The fiber sorbent according to the present invention is capable of efficiently adsorbing a relatively low concentration of carbon dioxide, particularly, carbon dioxide in the atmosphere, and an energy efficiency is good because the energy source required for desorption of carbon dioxide is free, and direct heating of the sorbent is possible.

Abstract: Disclosed are novel solutions in which a preexisting sediment capping system is integrated with improvements such as a cap ingredient processing and delivery apparatus, cap processing method and novel compositional cap product, whereby a hazardous site is remediated by delivering at least one novel cap composition layer over the contaminated subaqueous waterway or terrestrial substrate floor. One embodiment includes a powdered activated carbon (“PAC”) based cap layer produced by the system and methodology disclosed, the cap layer ingredients comprising predetermined ratio amounts of dry PAC and dry powdered 2-Hydroxypropyl guar gum (“HGG”) used as a safe and effective delivery ingredient, blended in a cap processing and delivering apparatus with a dewatered sand semi-slurry, the processed resulting capping composition being delivered in a manner such that a novel PAC cap layer is provided to a cap placement area in need of remediation.

Abstract: Described herein relates to an optimum, low maintenance and low-cost filtration media which may be implemented near a source water location as a pretreatment to remove tannic acid and/or humic acid (color) from dissolved natural organic matter (NOM) (i.e., tannic acid, humic acid) to impede the prompt production of disinfection by-products collectively termed trihalomethanes in drinking water treatment processes. In an embodiment, the filtration media may comprise a composition having a ratio of at least 83% sand, at most 5% clay, at most 6% ZVI and at most 6% perlite by percent volume.
