Ultrasonic Liposome Preparation for Pharmaceuticals and Cosmeceuticals

Liposomes works as carriers for active agents. Ultrasound is an effective tool to prepare and form the liposomes for the entrapment of active agents. Before encapsulation, the liposomes tend to form clusters due to the surface charge-charge interaction of phospholipid polar heads (Mickova et al. 2008), furthermore they have to be opened. By way of example, Zhu et al. (2003) describe the ...

Three–dimensional oil and gas pool–forming dynamic simulation system: principle, method and applications

Based on the theories and methods of system engineering, the reconstruction of physical space for oil and gas generation, expulsion, migration, accumulation and diffusion is realised by combining the dynamics simulation with topological structure simulation and applying the topological structure simulation. The integral non–linear process of petroleum system is described successfully with the ...

Determination of total antioxidant capacity of green teas by the ferric reducing/antioxidant power assay

The tea plant (Camellia sinesis L.) is grown in about 30 countries worldwide (Graham, 1992). It grows best in tropical and subtropical areas with adequate rainfall, good drainage, and slightly acidic soil (Graham, 1999). Tea (Camellia sinesis) is also the most widely consumed beverage worldwide for its desirable aroma, taste and putative positive physiological functions (Zhu et al., 2002; ...

Optimize your completion by reducing proppant embedment

Choosing the right proppant for the right application, instead of using the same proppant in every hydraulic fracturing application, can reduce cost per BOE. In a clay-rich, soft formation, for example, proppant choice is vital to reduce embedment. What is embedment? When completing a well in a clay-rich formation, such as the Niobrara in northeastern Colorado and adjacent parts of Wyoming, ...

Antibiotic resistance genes a growing problem in chinese estuaries

Large amounts of antibiotic resistance genes (ARGs) have been found throughout estuaries in coastal China, and scientists say they’re causing potentially dangerous changes to local bacteria. When bacteria mutate and become resistant to antibiotics, it endangers human health and life. If antibiotics can’t work properly, infectious diseases will increase, and health-care costs will ...
