The calculated partial charges and bond polarities of the model are consistent with the hydrophilic properties of brown coal. Water molecules within the model exert the major stabilisation through H-bonds and electrostatic interactions. Calculated values of bond lengths and angles of the inorganic ...
The primary reason for this difference was the substantial variation in the physicochemical properties of OA, including its functional group composition, polar characteristics, molecular weight, and compound structure. To date, only a limited number of components have been unequivocally identified, ...
The natural products synthesized by organisms that were living a long time ago gave rise to their molecular fossils. These can consist of either the original unchanged compounds or they may undergo peripheral transformations in which their skeletons rema
It is found that CO2 has much stronger adsorption ability on brown coal than CH4. The adsorption amounts of CO2/CH4 increase with pressure but have a decreasing trend with temperature. High adsorption selectivity of CO2/CH4 is observed with pressure lower than 0.1 MPa. In addition, the ...

The dominance of such hydrogen-rich kerogen (mainly Type II) was confirmed from the multi-geochemical ratios, including high hydrogen/carbon atomic of more than 1.30 and high A-factor of more than 0.60. This claim agrees with the molecular structure of the kerogen derived from Py–GC results...

A variety of approaches had been employed for the characterization of F. oxysporum f. sp. lycopersici isolates. Elias et al.23 studied the population structure of Fol based on RFLP analysis of the genomic DNA which provided genetic evidence that Vegetative Compatibility Grouping (VCG) was an ...
