Sequestration of Drugs from Biomolecular and Biomimicking Environments: Spectroscopic and Calorimetric Studies

Colloids and Interfaces, 2023
The binding of drugs to nucleic acids, proteins, lipids, amino acids, and other biological receptors is necessary for the transportation of drugs. However, various side effects may also originate if the bound drug molecules are not dissociated from the ...

Chemical Derivatization in Flow Analysis

Molecules, 2022
Chemical derivatization for improving selectivity and/or sensitivity is a common practice in analytical chemistry. It is particularly attractive in flow analysis in view of its highly reproducible reagent addition(s) and controlled timing.

Simulation of Crevice and Pitting Corrosion Using the Orthogonal Collocation Method

Journal of King Saud University: Engineering Sciences, 1996
Two dangerous forms of localized corrosion are pitting and crevice corrosion. In pitting corrosion, pits are formed as a result of differences in oxygen and ion concentration at the base of a pit compared with the surface.
