Polyvinyl pyrrolidone (PVP) in cataract surgery.
Early reformation of the anterior chamber after intraocular surgery is of paramount importance, its absence or delay leading to peripheral anterior synechiae and aphakic glaucoma (Troncoso, 1933; Kronfeld and Grossman, 1941; McLean, I94I; Meyer and Sternberg, 1950). Selinger (1937) injected air after cataract operations to restore the normal curvature of the cornea. He concluded that air preven...
متن کاملNon - Isothermal Depolarization Current Studies in Polyvinyl Pyrrolidone ( PVP ) Foil Electrets
Thermally stimulated depolarization current (TSDC) characteristics of Polyvinyl Pyrrolidone (PVP) electrets are studies in the temperature range 30 to 210 C as functions of the polarizing field (5 to 100kV/cm) and polarizing temperature (40 to 80C). The TSDC spectra comprise two maxima, namely, β and α with their respective locations around 90 C and 172.5 C. These are attributed to dipoleorient...

Solute Solvent Interactions of Polyvinyl Pyrrolidone Wrapped Single Walled Carbon Nanotubes (PVP-SWNTs) in Water by Viscometric Studies
Polymer wrapped single walled carbon nanotubes (SWNTs) have been synthesized to improve the solubility of SWNTs in water. The present study deals with experiments so as to highlight the solute solvent interactions during the solubilisation of polyvinyl pyrrolidone wrapped single walled carbon nanotubes (PVP-SWNTs) in water by viscometric methods. Viscosity values of both PVP and PVP-SWNTs have ...
