Polyelectrolyte Titration: Theory and Experiment

Charge determination of proteins with polyelectrolyte titration.

A recently developed photometric version of polyelectrolyte titration was applied for the determination of the number of charged residues on globular proteins. Based on the observation that oppositely charged polyelectrolytes form, in general, stoichiometric polyelectrolyte complexes, the protein solutions were incubated in excess with an oppositely charged polyelectrolyte, and the residual amo...

THEORY, EXPERIMENT AND PRACTICE OF SLAG ATTACK OF REFRACTORIES

Penetration and dissolution mechanisms are reviewed for predominantly single-phase oxide, two phase oxide and oxide-carbon composite refractories by liquid silicate slags. Theoretical models of these processes, as well as static (sessile drop, dipping and crucible) and dynamic (rotating finger and rotary slag) experimental tests, along with their practical limitations are considered. Direct (co...

Theory of Polyelectrolyte Solutions

Polyelectrolyte pKa from experiment and molecular dynamics simulation

The pKa of a polyelectrolyte has been determined experimentally by potentiometric titration and computed using Molecular Dynamics (MD) constant pH (CpH)methodology, which allows the pKa of each titratable site along the polymer backbone to be determined separately, a procedure which is not possible by current experimental techniques. By using experimental results within the CpHMD method, the si...

Theory , Experiment and Economics

I t is now over thirty years since research was initiated in the laboratory experimental study of market behavior and performance.' This essay provides my interpretation of what the implications of this type of work are for the study of economics. The essay is not intended as a systematic survey of the field, although examples will be cited where appropriate and necessary. The reader can find t...
