Micromixers?a review
Nam-Trung Nguyen,Zhigang Wu +1 more
TL;DR: In this paper, the authors report the progress on the recent development of micromixers and present different types and designs of active and passive MCMs, as well as the operation points of the MCMs.
Journal ArticleDOI
The Maxwell-Stefan approach to mass transfer
Rajamani Krishna,J.A. Wesselingh +1 more
TL;DR: In this paper, the limitations of the Fick's law for describing diffusion are discussed and it is argued that the Maxwell-Stefan formulation provides the most general and convenient approach for describing mass transport which takes proper account of thermodynamic non-idealities and influence of external force fields.

Chemical and Physical Structure of Polymers as Carriers for Controlled Release of Bioactive Agents: A Review
Robert Langer,Nicholas A. Peppas +1 more
TL;DR: In a controlled release system, a drug, pesticide, or other bioactive agent is incorporated into a carrier, generally a polymeric material as mentioned in this paper, and the rate of release of the substance is determined by the properties of the polymer itself and is only weakly dependent on environmental factors.
