The vest is activated through an endothermic reaction.
This confirmed that the residue of the sol-gel process vaporized up to 200[degrees]C and endothermic reaction by crystallization occurred.
Water content through TMT is based on the endothermic reaction between 2,2-dimethoxypropane (DMP) and water.
The average temperature of combustion chamber is 5782 K, which is 51.71% greater than 3811.17 K calculated by the thermodynamic calculation of the model engine combustion chamber; this is the result due to ignoring the middle of multistep endothermic reaction process when the single-step global chemical reaction is adopted.
Increased SF implies more steam supplied to the gasifier; hence the reaction of char in the combustion zone takes place under reach-steam conditions, which implies more of the char reacting with the steam through the endothermic reaction R5 to produce [H.sub.2] and CO.
Traditionally, ethylene is obtained from the thermal catalytic cracking of petroleum and natural gas upon an endothermic reaction requiring high temperatures (600[degrees]C-1000[degrees]C) [2].
CDM is an endothermic reaction and high temperature is favored thermodynamically and both hydrogen and carbon filaments are produced according to Eq.
They have come up with the idea of applying the same endothermic reaction used in cold compress packs to numb skin before the needle punctures it.
Polyfil's patented technology uses 0.08-micron nanoparticles of calcium carbonate in an endothermic reaction that yields only carbon dioxide, water, and citric salts, whereas most endothermic chemical foaming agents (CFAs) reportedly also produce soda ash, which can cause plateout and corrosion.
In terms of processing, it means that additional heat is needed to finish the vulcanization because the material will absorb energy to complete the endothermic reaction prior to vulcanization.
