The enthalpy of combustion of propane gas where products do not return to standard state, for example where the hot gases including water vapor exit a chimney, (known as lower heating value) is −2043.455 kJ/mol. [29] The lower heat value is the amount of heat available from burning the substance where the combustion products are vented to the ...
Graphene doped with various gaseous species (both acceptors and donors) can be returned to an undoped state by gentle heating in a vacuum. [88] [90] Even for dopant concentrations in excess of 10 12 cm −2, carrier mobility exhibits no observable change. [90] Graphene doped with potassium in ultra-high vacuum at low temperature can reduce ...
