    Abstract: Corrosion control in reinforced concrete is generally disclosed. Some example embodiments may include concrete including aggregate, cement, and/or microcapsules distributed within the cement, where the individual microcapsules may include a high pH salt substantially contained within an acid-soluble shell. If the pH of the concrete decreases, the acid soluble shell may swell and/or dissolve, such as below a pH of about 11, which may release the high pH salt. The high pH salt may locally increase the pH of the concrete. By increasing the pH above about pH 11, corrosion of steel rebar may be prevented and/or reduced.

    Abstract: A method of preparing nano-dispersed high-all-trans-carotenoid microcapsules is provided, comprising: preparing 10-20% carotenoid suspension by milling the high-all trans-carotenoid crystals with dichloromethane until the particle size thereof is in the range of 2-5 μm, then supplying the suspension together with preheated dichloromethane of another pass into a dissolving tank to obtain a solution of 0.5-2%; delivering the solution together with ethanol or isopropanol into a crystallization device having high gravity rotating packed bed simultaneously and continuously, and then into a wiped-film evaporator for desolvation until the solid content is 10-20%, then a transparent alcohol dispersion of carotenoid is obtained; mashing the alcohol dispersion together with an aqueous solution containing an antioxidant and protective colloid and spray drying to obtain nano-dispersed high-all-trans-carotenoid microcapsules. As the crystals are nano-dispersed and the content of trans-isomer is more than 90%, the carotenoid microcapsules of present inventions exhibit high bioavailability.
