Comparative studies of lipase-catalyzed hydrolysis of soy oil in solvent-free system were carried out in shaking bath and in ultrasonic bath. A suitable ultrasonic power of 1.64 W cm(-2) was determined to guarantee satisfactory hydrolysis extent and lipase activity. The influence of temperature, pH, enzyme concentration and water/oil ratio was investigated(More)
Comparative studies of lipase-catalyzed hydrolysis of soy oil takes place at the interface between the oil and the aqueous solution in solvent-free system were carried out in shaking bath and in ultrasonic bath. The interfacial area between the oil phase and the aqueous phase influences the rate of hydrolysis. Compared to shaking bath, ultrasonic shaking(More)
Enhancement of both cobalt leaching from LiCoO2 and acid utilization efficiency (AUE) in microbial fuel cells (MFCs) was successfully achieved by the addition of Cu(II). A dosage of 10mg/L Cu(II) improved both cobalt leaching up to 308% and AUE of 171% compared to the controls with no presence of Cu(II). The apparent activation energy of cobalt leaching(More)
Bioanodes formed at an optimal potential of 200 mV vs. SHE and biocathodes developed at -300 mV vs. SHE in bioelectrochemical cells (BECs) enhanced the subsequent performances of microbial fuel cells (MFCs) compared to the un-treated controls. While the startup times were reduced to 320 h (bioanodes) and 420-440 h (biocathodes), PCP degradation rates were(More)
Seven impurities in agomelatine drug substance were determined by a newly developed RP-HPLC method. Structures of potential impurities were confirmed by NMR and IR analysis. Efficient chromatographic separation was achieved on Hypersil BDS C18 column (250 mm × 4.6 mm, 5 μm) in gradient mode by using a binary mixture of potassium dihydrogen phosphate (15 mM,(More)
This paper presents an approach of automatically generating abstract paintings of Malevich Style. Through parameterized program and flexible production processes, we successfully generated images mimicking the styles of the abstract artist Kazimir Malevich, having classified different styles of his paintings. The generated results using the basic components(More)
5-n-butyl-4-{4-[2-(1H-tetrazole-5-yl)-1H-pyrrol-1-yl]phenylmethyl}-2,4-dihydro-2-(2,6-dichlorophenyl)-3H-1,2,4-triazol-3-one (Ib), a new nonpeptide angiotensin AT1-receptor antagonist, has been observed to play a positive role in the treatment of hypertension in preclinical tests. Four process impurities of Ib were detected by LC-UV and LC/ESI-MS, and the(More)
Currently, nanosizing is becoming increasingly prevalent as an efficient way for the improvement of oral drug absorption. This study mainly focuses on two points, namely the crystal properties, and the in vitro and in vivo characterizations of drug crystals during the nanosizing process. We used glyburide, an oral type 2 diabetes (T2D) medication, as our(More)
