Zeolite catalysts with micropores present good catalytic characteristics in biomass catalytic pyrolysis process. However, large-molecule oxygenates produced from pyrolysis cannot enter their pores and would form coke on their surfaces, which decreases hydrocarbon yield and deactivates catalyst ra...

Supercritical fluids have been established as alternative foaming agents in various polymers as well as nanocomposite systems. Most recently, supercritical carbon dioxide (scCO2) has also been used in some studies as a medium of clay dispersion in the polymer matrix providing a solvent-free fabri...

A new model is constructed to predict the electric spark sensitivity of nitramines. Genetic algorithm was employed to select the optimal subset of descriptors which have significant contribution to the electric spark sensitivity from various calculated molecular structure descriptors. The novel m...

This study investigates the intercalation of low molecular weight poly(ethylene glycol), PEG1000, into a montmorillonite-type Anatolian clay mineral (MMTA) using ultrasound sonication in a solvent free medium to produce a new type of organoclay with improved thermal properties. The results from t...
