a–i, Results are shown for a model with no barrier to CO2diffusion out of the pyrenoid matrix (a–c), a model with thylakoid stacks serving as diffusion barriers (d–f) and a model with an impermeable starch sheath (g–i).a,d,g, Schematics of the modelled chloroplast employing LCIB...
The field of gas flow modeling has garnered growing attention from both engineers and researchers. The reason is that the methane-hydrogen mixture is a promising energy carrier, and its application is rapidly increasing with the development of technical equipment and the demand for hydrogen as an ...
The maximum power point of the photovoltaics is designated with a dot. (b) Current density, CO yield and solar-to-CO conversion efficiency of the device during an 18-h stability test. For long-term testing of the complete device, a CO2-saturated solution of 0.5 M NaHCO3 was used as ...

Fig. 2. Flow diagram of the simulation, technical and economic analysis of the proposed plants. 2.3. Carbon dioxide (CO2) emissions from conventional cement plant In clinker production, CO2 emissions primarily result from fuel combustion and the calcination reaction in the calciner, which also produ...

“A soil deal for Europe” to lead the transition towards healthy soils by 2030. One objective of the mission is to conserve and restore carbon stocks in soil. One suggestion to catalyse this transition is to establish a trading system for CO2certificates from agricultural soil. If farmers ...
