... to the aggregation of small nanoparticles, especially at high AgNO 3 concentration. Figure 5 shows the TGA curves obtained for pure BC and BC/silver nanocomposites. For pure BC (Fig. 5a ), weight loss can be divided into two stages, which are from ambient temperature to 100 °C and from 100 to 400 °C...

... pH (pH 4), rather than the popular belief that it occurs in the physiological environment. Actually, the peptide lost its β -sheet structure and formed irregular aggregates in the condition around pH 7. Our results demonstrated that the extended conformation of peptide backbone caused...
