Effect of periodic backwash in the submerged membrane adsorption hybrid system [PDF]

, 2006
The submerged membrane adsorption hybrid system (SMAHS) is an attractive solution in treating wastewater; however it faces membrane fouling although to a less extent.

Nonlinear kinetics of ferritin adsorption

Biophysical Journal, 1993
The adsorption of ferritin at a methylized quartz surface was measured with off-null ellipsometry and transmission electron microscopy. An initial lag-phase was seen, followed by an accelerating adsorption leading to mass transport limitation of the reaction. The rate of adsorption then decreased at a surface concentration far below monolayer coverage,

History dependence of protein adsorption kinetics [PDF]

Proceedings of the National Academy of Sciences, 2001
The behavior of proteins at biological and synthetic interfaces is often characterized by a strong history dependence caused by long relaxation times or irreversible transitions. In this work, we introduce the rate of adsorption as a means to systematically quantify the extent, and identify the underlying causes, of history dependence.

Kinetic Modeling of Isothermal or Non-isothermal Adsorption in a Pellet: Application to Adsorption Heat Pumps [PDF]

, 2010
Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption process. Because the heat effects associated with adsorption are comparatively large, the assumption of isothermal behavior is a ...

Humidity Effect on Adsorption Kinetics of Aromatic and Chlorinated Hydrocarbon Vapors onto Fe2O3 Thin Film

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
In this study, the influence of relative humidity on amorphous Fe2O3 thin film’ sensing properties towards aromatic and chlorinated hydrocarbon vapor and their adsorption kinetics were examined systematically. The sensing results showed that the relative
