Kinetic and Thermodynamic Aspects of Ytterbium Adsorption on Sand

Kinetic and thermodynamic control of protein adsorption.

Control of nonspecific protein adsorption is very important for the design of biocompatible and biomimetic materials as well as drug carriers. Grafted polymer layers can be used to prevent protein adsorption. We have studied the molecular factors that determine the equilibrium and kinetic control of protein adsorption by grafted polymer layers. We find that polymers that are not attracted to th...

Kinetic and thermodynamic studies of adsorption of 4-chloro-2-nitrophenol on nano- Ti02

Adsorption capacity of 4-chloro-2-nitrophenol (4C2NP) onto nano-Ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-TiO2 dosage, initial pH and initial 4C2NP concentration. Optimum conditions for 4C2NP adsorptionwere found to be initial pH z 2, nano-TiO2 closer- 0.01 g and equilibrium time 1 h. The adsorptionkine...

Thermodynamic and kinetic aspects of fat crystallization.

Naturally occurring fats are multi-component mixtures of triacylglycerols (TAGs), which are triesters of fatty acids with glycerol, and of which there are many chemically distinct compounds. Due to the importance of fats to the food and consumer products industries, fat crystallization has been studied for many years and many intricate features of TAG interactions, complicated by polymorphism, ...

Thermodynamic and kinetic aspects of interfacial decohesion

Thermodynamic and kinetic aspects of interfacial decohesion are analyzed for a uniformly stressed interface in the presence of an embrittling impurity. During the interfacial separation, the impurity penetrates into the interface and reduces it cohesion. Rice (1976) and Hirth and Rice (1980) analyzed the thermodynamics of this process in great detail with emphasis on the limiting cases of infin...
