Journal ArticleDOI
Isoconversional kinetic analysis of decomposition of nitroimidazoles: Friedman method vs Flynn-Wall-Ozawa method.
TL;DR: The present study may be helpful in understanding how the position of NO2 group affects the decomposition kinetics of substituted imidazoles.
Journal ArticleDOI
Review on Melt Cast Explosives
TL;DR: A systematic overview of melt cast explosives can be found in this paper, where the authors discuss the main drawbacks of existing melt cast formulations, such as exudation, high volume change from liquid to solid, super cooling, irreversible growth, fragility and unpredictable sensitivity.
Journal ArticleDOI
Incorporation of support vector machines in the LIBS toolbox for sensitive and robust classification amidst unexpected sample and system variability.
Narahara Chari Dingari,Ishan Barman,Ashwin Kumar Myakalwar,Surya P. Tewari,Manoj Kumar Gundawar +4 more
TL;DR: It is demonstrated that the application of SVM enables statistically significant improvements in prospective classification accuracy (sensitivity) and the improved sensitivity and robustness observed here will facilitate application of the proposed LIBS-SVM toolbox for screening drugs and detecting counterfeit samples, as well as in related areas of forensic and biological sample analysis.
Journal ArticleDOI
Laser-induced breakdown spectroscopy-based investigation and classification of pharmaceutical tablets using multivariate chemometric analysis.
Ashwin Kumar Myakalwar,S. Sreedhar,Ishan Barman,Narahara Chari Dingari,S. Venugopal Rao,P. Prem Kiran,Surya P. Tewari,G. Manoj Kumar +7 more
TL;DR: In this paper, the authors report the effectiveness of laser-induced breakdown spectroscopy (LIBS) in probing the content of pharmaceutical tablets and also investigate its feasibility for routine classification.
Journal ArticleDOI
