  • acidic
  • As noted earlier, the titration curves of simple amino acids display two inflection points, one due to the strongly acidic carboxyl group (pK a 1 = 1.8 to 2.4), and the other for the less acidic ammonium function (pK a 2 = 8.8 to 9.7). (libretexts.org)
  • indicates
  • The white profile superimposed on the 2D-map indicates the position of the Dirac point estimated from the profiles such as in (b). (b) Line profiles extracted from the 2D-map showing the gate dependence of graphene resistance in four different solutions, where the shift in Dirac point is discernible. (nih.gov)
  • values
  • A good correlation between the isoelectric point values of insulin and its derivatives and their fusion properties was found. (biochemj.org)
  • c) Measured and calculated Dirac point profiles as a function of pH at 2 different ionic strength values. (nih.gov)
  • Figure 2(a) shows a typical measurement on bare graphene (as-prepared or unmodified graphene is referred to here as bare graphene) for varying pH values at two different ionic strengths (1 mM: I and 1000 mM: M). From every cycle of field-effect scan, as shown in Fig. 2(b), we extract the Dirac point ( or the gate voltage at resistance maximum), which is also overlaid in Fig. 2(a). (nih.gov)
  • range
  • It has been found that stable dispersions of paint resins which incorporate an antimony-containing tin oxide based conductive pigment can be achieved when the isoelectric point of the pigment particles has a value in the range of from about 5 to about 9. (google.com)
  • The isoelectric points range from 5.5 to 6.2. (libretexts.org)
