Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 387-404 doi: 10.1007/s11705-014-1457-3

Abstract: Nanocarriers have been designed to enhance their cellular uptake via endocytosis but following theircellular uptake, endosomal escape is the rate limiting step which restricts the value associated withthe enhanced uptake by nanocarriers.In this review, we first discuss different endocytic uptake pathways and endosomal escape mechanisms.we highlight the important design elements of recent virus-based nanocarriers for efficient cellular uptake

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 2,   Pages 233-239 doi: 10.1007/s11783-007-0040-2

Abstract: Enhanced biological phosphorus removal (EBPR) is a commonly used and sustainable method for phosphorusThe interruption of anaerobic HAc-uptake and phosphorus-release occurs when the glycogen in the phosphorus-accumulating-organismscondition of lower initial HAc-COD, HAc became the limiting factor after some time for anaerobic HAc uptakeUnder the condition of higher initial HAc-COD, HAc uptake was stopped because of the depletion of glycogenThe calibrated kinetic parameters of the HAc-uptake and phosphorus-release model were evaluated as follows
