The oxidant forms the most part of the propellants, and ammonium perchlorate is the most applicable oxidizer in composite solid propellants. Therefore, its thermal decomposition and immunity properties have been a great effect on the propellants properties. The using of polymeric additives is one of the different methods for improving the thermal and immunological properties of ammonium perchlo...
Pyrolysis-gas chromatography-mass spectrometry (MS) was used to identify the major organic products produced by pyrolysis of three foundry sand resins: (i) Novolac and (ii) phenolic urethane (PU) (both phenol-formaldehyde based resins) and (iii) furan (furfuryl alcohol based resin). These resins are used in the metal casting industry as a "sand binder" for making cores (used to produce cavities...
To investigate the reaction kinetics of the solid-state degradation process of enalapril maleate, a Fourier transform infrared microspectroscope equipped with thermal analyzer (thermal FT-IR microscopic system) was used. The isothermal stability study was conducted at 120-130 degrees C for 1-2 h and changes in the three-dimensional plots of the IR spectra of enalapril maleate with respect to he...
