This study investigates the efficacy of a prepared Ni/θ-Al 2 O 3 catalyst during pyrolytic conversion Parachlorella kessleri HY-6 and compares results with non-catalytic conversion. The was characterized by techniques such as Brunauer–Emmett–Teller (BET) for surface area, acidity, X-ray powder diffraction (XRD). Isoconversional combined kinetic methods were used to kinetics process. at 10, 20, ...

      In this work, thermal degradation behavior of a fuel-rich energetic mixture containing epoxy binder was studied by thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. Variation of the thermal degradation activation energy of the mixture was evaluated by differential and integral isoconversional methods via ...

The co-precipitation technique was used to successfully produce nanometer cobalt ferrite (CoF). Utilizing the solvent-antisolvent approach, reduction in size of sensitive HEM 3-nitro-2,4-dihydro-3H-1,2,4-triazol-5-one (NTO) effectively achieved. Using simultaneous thermal analysis, effect 5% by mass CoF on thermolysis NTO and nanosize (r-NTO) investigated. kinetic parameter r-NTO presence addit...
