| 1 | Nitration of Jharia basin coals,India:a study of structural modifications by XRD and FTIR techniques显示文摘Four coal samples from Jharia basin,India are treated with nitric acid in glacial acetic acid and aqueous media to find out the chemical,petrographic and spatial structure of the organic mass by X-ray diffraction(XRD)and Fourier Transform Infrared Spectroscopy(FTIR)techniques.X-ray parameters of coal like interlayer spacing(d_(002)),crystallite size(L_(c)),aroamticity(f_(a)),average number of aromatic layers(N_(c)),and coal rank(I_(26)/I_(20))have been determined using profilefitting software.Considerable variation is observed in treated coals in comparison to the demineralized coals.The d_(002)values of treated coals have increased in both the media showing increase in disordering of organic moieties.A linear relationship has been observed between d_(002)values with the volatile matter of the coals.Similarly,the d_(002)values show linear relationship with C_(dmf) contents for demineralized as well as for the treated coals in both the media.The L_(c) and N_(c) values have decreased in treated coals corresponding to demineralized coals.The present study shows that nitration in both the media is capable of removing the aliphatic side chains from the coals and aromaticity(f_(a))increases with increase in rank and shows a linear relationship with the vitrinite reflectance.The corresponding I_(26)/I_(20)values are least for treated coals in glacial acetic acid medium followed by raw and then to treated coals in aqueous medium.FTIR studies show that coal arenes of the raw coals are converted into nitro-arenes in structurally modified coals(SMCs)in both the media,the corresponding bands at 1550-1490 and 1355-1315 cm^(-1) respectively.FTIR study confirms that nitration is the predominant phenomenon,though,oxidation and nitration phenomena takes place simultaneously during treatment with nitric acid to form SMCs.In comparison to raw coals,the SMCs show higher aromaticity and may be easily converted to coal derived products like activated carbon and specialty carbon materials. | Prabal Boral Atul K.Varma Sudip Maity | 2021 | International Journal of Coal Science & Technology2021,8,5: | 2 |
| 2 | Predictive distribution modeling of Swertia bimaculata in Darjeeling-Sikkim Eastern Himalaya using MaxEnt: current and future scenarios显示文摘Background:As global temperatures continue to rise,species distribution modeling is a suitable tool for identifying rare and endangered species most at risk of extinction,along with tracking shifting geographical range.Methods:The present study investigates the potential distribution of Swertia bimaculata in the Darjeeling-Sikkim region of Eastern Himalaya in current and future climate scenarios of GFDL-CM3(Geophysical Fluid Dynamics Laboratory-Climate Model 3)for the year 2050 and year 2070 through MaxEnt presence data modeling.Two sets of variables were used for modeling current scenario.The models were evaluated using AUC(area under the curve)values and TSS(true skill statistic).Results:Habitat assessment of the species shows low and sporadic distribution within the study area.A significant decrease is observed in the possible range of the species in the future climate scenario with the habitat decreasing from 869.48 to 0 km^(2).Resultant maps from the modeling process show significant upward shifting of the species range along the altitudinal gradient.Still,results should be taken with caution given the low number of occurrences used in the modeling.Conclusions:The results thus highlight the vulnerability of the species towards extinction in the near future. | Debasruti Boral Saurav Moktan | 2021 | Ecological Processes2021,10,1: | 2 |
