O-5: Preparation of Multi-Component Drug Delivery Systems

Background: Despite global interest, the development of single step processes for the preparation of effective drug delivery systems still faces numerous challenges. There is great demand for processing methods that are efficient, flexible, scalable and economical for the generation of wide range of encapsulated structures. Over the past few decades, electrohydrodynamic (EHD) processing has rec...

Multi-source/component spray coating for polymer solar cells.

A multi-source/component spray coating process to fabricate the photoactive layers in polymer solar cells is demonstrated. Well-defined domains consisting of polymer:fullerene heterojunctions are constructed in ambient conditions using an alternating spray deposition method. This approach preserves the integrity of the layer morphology while forming an interpenetrating donor (D)/acceptor (A) ne...

Polymer Percolation Threshold in Multi-Component HPMC Matrices Tablets.

INTRODUCTION The percolation theory studies the critical points or percolation thresholds of the system, where one component of the system undergoes a geometrical phase transition, starting to connect the whole system.The application of this theory to study the release rate of hydrophilic matrices allows to explain the changes in release kinetics of swellable matrix type system and results in a...

Absolute Acceleration Transfer Function of Secondary Systems Subjected to Multi- Component Earthquakes

The importance of the equipment and secondary systems in seismic design and performance evaluation is well recognized and has been the subject of many studies. In all of these studies, earthquake is considered as a single component, and in most of them the primary system is considered as shear building. Most attention has been concentrated on the response of secondary system and its response sp...
