Little is known about the early evolution of Venus and a potential habitable period during first one billion years. In particular, it remains unclear whether or not plate tectonics an active carbonate-silicate cycle were present. presence liquid water but without tectonics, weathering would have been limited to freshly produced basaltic crust, with carbon restricted crust atmosphere. With evapo...

Roughly 97 % of the European Union (EU)’s building stock is not considered energy efficient, and 75 to 85 it will still be in use 2050. Residential buildings account for around two thirds final consumption buildings. The rate at which new either replace old stock, or expand total about 1 per year. Similarly, current renovation existing EU 1–2 renovated each year.The transformation today’s elect...

This work presents the effect of atomic substitution on MnFe2O4–Na2CO3 thermochemical cycle for H2 production. The non-oxidative decarbonation/carbonation reaction mixture is investigated as starting reference. Repeated cycling results in a 30% loss reversibility due to an overall reduction reactive interfaces. Na2CO3 Li2CO3 decreases decarbonation onset temperature by about 100 °C, but almost ...

The reaction of carbon dioxide with a mixture of a superbase and alcohol affords a superbase alkylcarbonate salt via a process that can be reversed at elevated temperatures. To utilize the unique chemistry of superbases for carbon capture technology, it is essential to facilitate carbonation and decarbonation at desired temperatures in an easily controllable manner. Here, we demonstrate that th...

Calcium oxalates are naturally occurring biominerals and can be found as a byproduct of some industrial processes. Recently, new green method for carbon capture sequestration in stable calcium oxalate from oxalic acid produced by dioxide reduction was proposed. The reaction resulted high-quality weddellite crystals. Assessing the stability these crystals is crucial to forecast their reuse solid...

Abstract The characterization of particles in suspension river plumes contributes to the assessment net particulate organic carbon (POC) fluxes and a better understanding anthropogenic climatic impact on blue carbon. Prior POC analysis natural waters, inorganic (in form carbonates) must be removed. This step is generally carried out by acid leaching. However, presence mineral matrices turbid wa...
