Regulating drug release behavior and kinetics from matrix tablets based on fine particle-sized ethyl cellulose ether derivatives: an in vitro and in vivo evaluation.

Kifayat Ullah Shah et al.

TheScientificWorldJournal, 2012, 842348-842348 (2012-06-01)

The design and fabrication of sustained/controlled release dosage forms, employing new excipients capable of extending/controlling the release of drugs from the dosage forms over prolonged periods, has worked well in achieving optimally enhanced therapeutic levels of the drugs. In this

Functionalized graphene sheets as a versatile replacement for platinum in dye-sensitized solar cells.

Joseph D Roy-Mayhew et al.

ACS applied materials & interfaces, 4(5), 2794-2800 (2012-05-03)

Several techniques for fabricating functionalized graphene sheet (FGS) electrodes were tested for catalytic performance in dye-sensitized solar cells (DSSCs). By using ethyl cellulose as a sacrificial binder, and partially thermolyzing it, we were able to create electrodes which exhibited lower

Electrospun biphasic drug release polyvinylpyrrolidone/ethyl cellulose core/sheath nanofibers.

D G Yu et al.

Acta biomaterialia, 9(3), 5665-5672 (2012-10-27)

The capability of core/sheath nanofibers prepared using coaxial electrospinning to provide adjustable biphasic drug release was investigated. Using ketoprofen (KET) as the model drug, polyvinylpyrrolidone as the sheath polymer, and ethyl cellulose as the core matrix, the coaxial process could
