Abstract: Embodiments described herein relate to systems and methods for carbonating a liquid at ambient temperature. The system may include a liquid source; a carbon dioxide source; and a contactor for carbonating the liquid. The contactor may include channels and a sparge for carbonating liquid flowing through the channels. The system may produce a liquid having high levels of carbonation at ambient temperature. The sparge may generate microbubbles or nanobubbles to allow for cost-effective carbonation at ambient temperatures. The bubbles may have an average diameter of 100 ?m or less. The system may carbonate liquid at a rate of 1 gram to 10 grams carbon dioxide per liter.

Abstract: A blast debris protective harness includes a front shell portion and a rear shell portion joined together. Each of the front and rear shell portions has an inside shell member and an outside shell member. A cavity is defined between the inside shell member and the outside shell member. A ballistic insert is configured to be retained within the cavity. The harness is an outer garment.

Abstract: Polyester polyols are provided by reaction of FDCA with polyepoxides. The polyester polyols can be used as is or further reacted to produce thermoset polymers useful for coatings particularly for those providing corrosion resistance and flame resistance.
