Sol-gel synthesis of DyCrO and 10% Fe-doped DyCrO nanoparticles with enhanced photocatalytic hydrogen production abilities.

DyCrO and 10% Fe-doped DyCrO nanoparticles have been synthesized using a sol-gel method to investigate their performance in photocatalytic hydrogen production from water. The synthesized nanoparticles have been characterized by performing X-ray diffraction, energy dispersive X-ray spectroscopy and UV-visible spectrophotometric measurements. In addition, field emission scanning electron microscopy has been performed to observe their size and shape.

Effect of channeling agents on the release pattern of theophylline from kollidon SR based matrix tablets.

The purpose of the present study was to investigate the effect of channeling agent on the release profile of theophylline from Kollidon SR based matrix systems. Matrix tablets of theophylline using Kollidon SR which is plastic in nature were prepared by direct compression process. NaCl and PEG 1500 were used as channeling agents.
