Slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). Susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. Maximum glucose yi...

Thermal energy storage includes sensible, latent and thermochemical heat storage. The latter is particularly interesting because the stored as a chemical potential, which reduces loss in long-term applications. viability of systems strongly depends on density material. development high materials thus essential to achieve compact suitable for wide range A new sol-gel composite material investiga...
