    Abstract: Disclosed herein are a variety of systems, compositions, and methods for reversibly storing electrical energy in a redox flow battery with a unit cell potential equal to or greater than 3.5 volts. The systems include a positive section, a negative section, and an electroactive bipolar redox molecule comprising an anolyte moiety and a catholyte moiety separated by a non-conjugating insulating linker. The catholyte moiety comprises para-dimethoxybenzene and the non-conjugating insulating linker comprises at least two -CX2 linkers, wherein X comprises at least one atom selected from the group consisting of hydrogen and heteroatoms. The positive section comprises a first metal electrode in contact with the electroactive bipolar redox molecule and a supporting electrolyte dissolved in a solvent. The negative section comprises a second metal electrode in contact with the electroactive bipolar redox molecule and additional electrolyte dissolved in additional solvent.

    Abstract: Disclosed herein are a variety of systems, compositions, and methods for reversibly storing electrical energy in a symmetric redox flow battery with a unit cell potential equal to or greater than 3 volts. The systems include a conjugated organic molecule, a positive section, and a negative section. The conjugated organic molecule comprises a pair of electron-donating groups and a pair of electron-withdrawing groups, wherein a first electron-donating group of the electron donating groups is one ring position from a first electron-withdrawing group of the electron-withdrawing groups, and wherein a second electron-donating group is one ring position from a second electron-withdrawing group of the electron-withdrawing groups. The positive section includes a first metal electrode in contact with a catholyte comprising a portion of the conjugated organic molecule. The negative section comprises a second metal electrode in contact with an anolyte including an additional portion of the conjugated organic molecule.

    Abstract: Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

    Abstract: Provided herein are functionalized branched alcohols comprising a glycosyl group, an ethylene oxide linker and a tail. The ethylene oxide linker comprises one or more units of ethylene oxide. The glycosyl group is a substituent structure of a cyclic monosaccharide. The tail comprises a branched paraffin or isomers thereof, the glycosyl group is attached to the ethylene oxide linker, and the ethylene oxide linker is attached to the tail. In an aspect, the glycosyl group is a substituent structure of glucose, mannose, galactose, sorbose, fructose, xylose, arabinose, ribose, lyxose, lactose, or maltose, or variants thereof. The tail can be a paraffin comprising 9 to 13 carbon atoms.
