Background: Algae are responsible for converting carbon dioxide into oxygen. However more than 20% of the world\\\'s oceans lack algae growth. The essential nutrient that is lacking in the algae-deficient surface waters is iron. However this iron must be (i) on the surface so that the algae can convert carbon dioxide to oxygen via photosynthesis and (ii) biologically available so that algae can use it. Technology Description: This technology describes the composition of and the method of production for water-buoyant particles that contain bioavailable iron.

Rutgers researchers have developed a method for separating carbon dioxide from a mixture of gases by way of passing said mixture through a porous polymeric coordination compound.

Carbon Upcycling Technologies is at an early stage of developing a process that sequesters carbon from CO2 in the form of a modified graphene product. The process itself requires a concentrated CO2 stream(such as the waste gas from coal fired power generation facilities refineries and other processing plants)as well as another solid carbon feedstock such as graphite or coal. Active carbon sites are generated on the solid carbon feedstock by repeatedly breaking molecular bonds on the solid. The active carbon reacts with the gaseous CO2 molecule.
