We entrapped lipase from Pseudomonas cepacia in polyallylamine-mediated biomimetic silica, and then applied entrapped lipase to the synthesis of biodiesel with soybean oil or waste cooking oil as a feedstock. The effects of reaction temperature, substrate molar ratio (methanol/oil) and n-hexane content (w/w of oil) were evaluated using response surface(More)
Triacylglycerol lipase from Pseudomonas cepacia and Fe3O4 magnetic nanoparticles were encapsulated simultaneously within biomimetic silica through the catalysis of polyallylamine. The encapsulation efficiency reached 96% with an activity recovery of 51%. After 5 h at 37°C, the activities of the free and encapsulated lipases decreased by 77 and 16%,(More)
In recent years, wireless sensor networks are widely used in various applications. This paper proposes a data gathering protocol with mobile relays to solve the partition problem of sensor network. When some sensor nodes have exhausted their batteries or are failure, some holes occur in the network topology. Because of the existence and enlargement of the(More)
