We also found, in several folios, visible areas with dissolution, spreading and smudges due to water-solubility of paints when in contact with moisture, like in the borders (Fig. 17d) and in the historiated initial with the image of Saint Catherine, which had its face blurred (Fig. 2g).
After 10 s dipping (blue curve), as expected, the interference fringes are no more visible due to the almost complete dissolution of the porous layer.
Direct evidence for the presence of such large dissolution features is only visible when exposed to the surface which may be problematic in urbanized areas.
Visible light tended to increase the dissolution of Ag-NP under most natural water conditions in comparison to dark conditions, whereas UV-light led to decreased dissolved Ag+ after longer exposure time.
Fine droplets of SE lipid formulation have been visible until the end of the dissolution test, which can confirm that not all ibuprofen was dissolved after 45 min. The dissolution profiles in the phosphate buffer show that after 30 min, more than 80% of ibuprofen is dissolved from all the liquid lipid formulations (Fig. 2b).
The electrodes recovered after the experiment had no visible alterations (e.g., mineral precipitation or dissolution of AgCl coating).
The progression of blood clot dissolution during the procedure was clearly visible as an increase in MR signal in the hole drilled by ultrasound, once it was filled with physiological serum.
Other characterisation techniques included specific surface area (BET), charge (zeta potential), composition and surface chemistry (XPS, ICP-MS and UV visible spectroscopy), crystal structure (TEM and XRD) and dissolution (UF-ICP-MS).
The lines of their sheathlike gowns are now barely visible; their faces seem to be suspended in perpetual dissolution, like those of Medardo Rosso's eternity-traveling children.
The numerous channels and pores visible in the micrograph showed the pathway through which dissolution medium could permeate into the drug-polymer matrix, swell the polymers, and widen the pore diameter which in turns would help the drug molecule to diffuse from the matrix into the dissolution medium.
