The behaviour of energetic solids subjected to simple shear loading is modelled to predict ignition. The model is transient, one dimensional and includes effects of thermal diffusion, plastic work and exothermic reaction with one-step irreversible Arrhenius kinetics. A common power-law constitutive model for shear stress which accounts for strain hardening, strain-rate hardening and thermal sof...

Poly methyl methacrylate (PMMA) cement produce exothermic reaction during its polymerization process, which damage the surrounding bone tissue during orthopedic surgery. Nanoparticles additives (magnesium oxide, hydroxyapatite, chitosan, barium sulfate and silica) and alternative monomers (glycidyl methacrylate(GMA) tri-methaxysilyl propyl methacrylate (3MPMA)), can be incorporated with the PMM...

This paper reports on the design of novel reactor for low-temperature growth of Vertically Aligned Carbon Nanotubes (VACNTs). Two mechanisms for selective heating catalytic nanoparticles were investigated: (i) a heating from exothermic reaction of catalytic oxidation and (ii) an induction heating. The requirements for efficient induction heating catalytic particles of size varying from micron t...

Thermal stability evaluation of exothermic chemical reactions is of great importance to the safer design and operation of chemical processes. Dominant reaction stoichiometries and their thermochemistry parameters are key elements in the evaluation process. Identification of significant reaction pathways under possible process conditions will lead to an understanding of the overall thermodynamic...

Ru(II) "piano-stool" complexes belong to group of biologically active metallocomplexes with promising anticancer activity. In this study, we investigate the reaction mechanism of [(η(6)-benzene)Ru(II)(en)(H(2)O)](2+) (en = ethylenediamine) complex binding to DNA by hybrid QM/MM computational techniques. The reaction when the Ru(II) complex is coordinated on N7-guanine from major groove is explo...

The theory of thermal explosion specifies the conditions for a "runaway" temperature rise in systems undergoing exothermic reaction or decomposition. It provides a means for predicting the probable behaviour of such systems in practice, even though they may depart appreciably from the ideal, and it can guide the choice both of experimental methods for hazard assessment and of measures for avoid...

STATEMENT OF PROBLEM Increasing the thickness of intraoral autopolymerizing hard denture base liners may result in a temperature rise and a burning sensation for patients. PURPOSE The purpose of the study was to determine whether increasing the thickness of hard autopolymerizing reline resin increases the temperature of the basal seat area of a denture during the polymerization process. MAT...

Oxidative coupling of methane (OCM) is an exothermic reaction that results in the temperature rise towards latter part reactor. This study reports consequence OCM product distribution after O 2 depletion at high temperatures.
