Tīmeklis2014. gada 25. apr. · Delivering sparingly water-soluble drugs from ethylcellulose (EC) coated pellets with a controlled-release pattern remains challenging. In the present study, hydrophilic polyvinylpyrrolidone (PVP) was used both as a binder and a pore-former in EC coated pellets to deliver sparingly water-soluble topiramate, and the key … TīmeklisThe diameter of the PVP/NaCl fibers shown in Fig. 2b is 200–300 nm, along with some small NaCl particles evenly distributed on the fiber surface. This characteristic of fiber diameters for PVP/NaCl fibers was caused by the increased precursor viscosity after the addition of NaCl. To improve the electrical conductivity of the composite films ...
TīmeklisTransfer a small portion of the solution to a test tube. The addition of a few drops of 1.5 M sodium chloride (NaCl) solution causes the suspension to turn darker yellow, then gray as the nanoparticles aggregate. Step 6.
