Developments in Heat Transfer Part 6 pot

wide reaction temperature range, high heat and mass transfer rates, fast reaction kinetic, low material prices, non toxic material. Thus, the combination of a porous shell with moisture- sensitive compound as xylitol would be useful for a material design of new functional microparticles for thermal and moisture management (Salaün et al., 2011). 6.
