Energetic materials have been used over time in civil and military applications. Concomitantly, studies were conducted focusing on the combustion mechanisms of these materials, including their kinetic and thermodynamic behavior during firing. The objective of this work was to systematically study the mechanisms of thermal decomposition of ammonium ...

Pure monoclinic P21/c VO2 thermochromic ceramics are fabricated based on an accessible and simple method using thermal decomposition synthesis in an organic medium. Well-developed submicron crystals with different morphologies are obtained when calcination temperature is varied from 500 to 700 °C. XRD shows that calcination temperature is necessary...

BackgroundBiomass pre-treatment is gaining attention as a standalone process to improve the qualitative aspect of the lignocellulosic material. It has been gaining ground in the power station by replacing the coal with the pre-treated biomass. In this context, this paper enlightens the operating condition of carrying out the torrefaction so that th...

We employed ReaxFF molecular dynamics (MD) to simulate the physicochemical properties of HMX nanoparticle at low temperatures. As the temperature increases, its physical and chemical properties change accompanying some transition, which is not reported by any previous studies. The Poisson Scoring Model was used to count phase transition. It is foun...

The sulfonated polyoxadiazole (SPOD) flame retardant fibers are prepared by wet spinning and modified by metal ions (Na+, Ca2+, Ba2+, and Mg2+). The structures of SPOD fibers are characterized by Fourier transform infrared spectrometry (FTIR), elements analysis (EA), inductively coupled plasma emission spectrometry (ICP), scanning electron microsco...
A new process using the selective decomposition of silver oxalate is presented and applied to the production of transparent electrodes on a polymer substrate. It is indeed shown that the silver oxalate Ag2C2O4 can be reduced to the metallic silver state by the focused laser beam of a photolithography machine (λ = 405 nm, spot size 5 µm, power betwe...

Toxic sodium cyanate is always present in cyanide-contaminated waste. A new technology for the efficient decomposition of toxic sodium cyanate by hematite was first proposed in this study. The decomposition of sodium cyanate under various atmospheres has been studied. Studies show that sodium cyanate decomposes above 782 °C in Ar and above 627 °C i...

This work aims at describing the computational study of thermal decomposition reaction of three oxypropenes: 2-(1-methylethoxy)propene, 2-ethoxypropene, and 2-butoxypropene. It was carried out in order to delve into the reaction mechanism proposed in experimental studies. Computational optimization calculations and frequencies of the structures wer...

Variability in the efficacy, safety, and quality of probiotic formulations depends on many factors, including process conditions used by manufacturers. Developing reliable analytical tools is therefore essential to quickly monitor manufacturing differences in probiotic samples for their quality assessment. Here, multi-strain probiotics from two pro...
