Afterward, zirconia oxide nitrate (ZrO(NO3)2, Sigma Aldrich Co) and calcium nitrate tetrahydrate (Ca(NO3)2·4H2O, Sigma Aldrich Co) were added into the mixture (molar ratio: ZrO(NO3)2:Ca(NO3)2·4H2O:TEOS = 1:3:2) and solution was stirred for 5 h at room temperature. Following ...
On a molar basis, about 31% of the sugar was directed to product biosynthesis (Table 2). In addition, N-acetyl-diaminopentane was secreted as the major by-product. However, no lysine production was observed, indicating that conversion of lysine to diaminopentane by the heterologous lysine ...
For filter media T1, the average mass concentration of Na and Mg was fairly found comparable; however, XRFs, Ca and K concentrations were found relatively low and incomparable (Fig. 5). The XRF based Ca were as low as 10 folds than the IC measurements. The reasons for this decrease in...
dB.ased on the GPC results, a degree of polymerization of 265 and a molar mass of 43,700 g/mol for unprotected DM0.4/CP0.6 was calculated. 3.2. siRNA Encapsulation Assay 3.2. siRNA Encapsulation Assay In order to enable the delivery of the siRNA molecule to target sites and especially ...
