Chinese forests cover most of the representative forest types in the Northern Hemisphere and function as a large carbon (C) sink in the global C cycle. The availability of long-term C dynamics observations is key to evaluating and understanding C sequest
However, the first-cycle Coulombic efficiency could increase by decreasing the specific surface area of the hard carbon to less than 8.0 m2/g [223]. Another study subjected to potato starch, the boron-doped carbon was prepared in a two-step hydrothermal reaction and carbonization with a yield ...
Consequently, variations in the capacity of soils to store carbon have tremendous impacts on the global carbon cycle and future climate4,5. This sensitivity of global climate to soil carbon storage presents both an obvious risk and a potentially powerful carbon mitigation tool6. The abundance of ...
This electrode material has a long lifetime, good power density and good cycle life. Liu et al. produced carbon aerogel based on resorcinol–formaldehyde and activated by CO2 [59]. This aerogel had a surface area of 3432 m2/g and yields a capacitance of 152 F/g. This electrode material ...
The carbon also exhibited a good cycle ability with a specific capacity of 356 mAh/g after 79 cycles at a current density of 0.5 C vs. Li+/Li [315]. 3.2.3. Phosphorous doping P–C bonds could enhance electrical conductivity by increasing the electron density around the Fermi level...
While this flux is small relative to the gross fluxes of carbon in the global carbon cycle, it is significant relative to the net fluxes to and from the atmosphere (Fig. 1; Regnier et al., 2022), and Earth system models currently do not simulate this lateral carbon transfer. However, ...
Carbonate precipitation is a major process in the global carbon cycle. It was recently proposed that authigenic carbonate (carbonate precipitated in situ at the sediment–water interface and/or within the sediment) played a major role in the carbon cycle throughout Earth’s history. The carbon iso...
