The variability of approximately 9% depends on the nature of the biomass material [36, 37] although most studies have used the carbon proportions between 40 to 50% depending on the requirements [38 43].

It was necessary to introduce the micro-spherical carbon to proportions beyond 60% m/m in order to reduce film resistances to less than 1 kΩ.
where p c is the proportion of carbon in dry organic matter (DW).
Elastic recoil detection analysis, infrared and Raman spectroscopies have been used to quantify, respectively, hydrogen content, the bonding and sp2 proportion carbon of thin films.
We measured several behaviors that may affect carbon storage: the proportion of parcel mown (or left unmown with woody vegetation), the number of large trees retained, the number of trees planted, how leaf litter was managed, the use of fertilizer, and the use of irrigation.
In this study, a geographically diverse "global" soil-spectral library with 4184 samples was augmented with up to 418 "local" calibration soil samples distributed across a 2nd-order Ugandan watershed to predict the amount of clay-size material (CLAY), soil organic carbon (SOC) and proportion of expansible 2 1 clays (termed "montmorillonite" or MT in the global library).
The study which considered more than 170 different countries combined ranks for natural forest loss, habitat conversion, marine captures, fertilizer use, water pollution, carbon emissions and proportion of threatened species.
A better indication of the importance of PAH carbon as a proportion of the total microbial carbon demand may be phenanthrene and fluoranthene mineralization, which (summed with naphthalene mineralization) on average supported 5.6% of bacterial carbon demand in the summer, 3.3% in the spring, but only 1.2% in winter.
The proportion of carbon present as carbonates, carbon-oxygenates and hydrocarbon species does not depend much on reaction temperature and photon energy.
