N,N- Dimethylcyclohexylamine (DMC). The amine solution loaded with CO2 is regenerated with the help of a temperature induced thermomorphic liquid-liquid-phase separation at moderate temperatures lying well below 100°C. The amines partition into a distinct organic phase, while the CO2 initially remains in the aqueous phase as HCO3- from which it is then liberated and recovered as a gas.
Commercial Opportunities: Since the dissociation of the amines from CO2 is brought about by the liquid-liquid miscibility gap, the solvent regeneration operates at much lower temperatures than in conventional CO2-capture processes and can thus be tailored to utilize previously unexploited waste heat sources. The low heat of reaction and dispensing with stripping steam leads to an extremely energy-efficient process for CO2 capture from industrial gases comparable with or superior to the best state-of-the-art technologies. Further advantages include the excellent CO2 absorption kinetics and the improved resistance to oxidative degradation.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
