In order to utilize a wider range of low-grade syngas, the syngas biomethanation was studied in this work with respect gas–liquid mass transfer and reactor start-up strategy. Two reactors, continuous stirred tank (CSTR) bubble column gas recirculation (BCR-C), were used experiment by feeding an artificial 20% H2, 50% CO, 30% CO2 into reactors at 55 °C. The results showed that CH4 productivity s...

Mechanochemistry meansmechanical breakage of intramolecular bonds by external force and must be differentiated from molecular solid-state chemistry, where contacts between micronized molecular solids are created by the mechanical action for mutual approach of the reacting centers. After an outline of the mechanistic differences, the varied mechanochemistry is discussed. Grinding, milling, shear...

Most food mixtures, where the liquid acts as a dispersion medium, are formed with participation of water and aqueous solutions,. The formation stable surface interactions in disperse systems is based on overcoming forces tension at interface between phases. aim research to analyze effect mechanical activation during stirring microwave exposure properties solutions. object distilled water, bottl...

To investigate the reparative efficacy of tissue-engineered osteochondral (TEO) graft for repairing the osteochondral defect in goat, we designed a double-chamber stirring bioreactor to construct the bone and cartilage composites simultaneously in one β-TCP scaffold and observed the reparative effect in vivo. The osteochondral defects were created in goats and all the animals were divided into ...
