Dislocation equilibrium conditions revisited

If there is an equilibrium arrangement of a given collection of dislocations, each having a fixed size and shape, in an externally loaded or unloaded elastic body, the corresponding potential energy will be stationary with respect to infinitesimal perturbations of the dislocation positions. This leads to the dislocation equilibrium conditions: the Peach– Koehler forces along the dislocation lin...

Equilibrium Bank Runs Revisited

In a Diamond and Dybvig (1983) environment, Green and Lin (2003) take a mechanism design approach and show that a bank run equilibrium cannot exist. Peck and Shell (2003) generalize their economic environment and show that it can. The bank run, however, does not emerge because of modifications to the economic environment but rather because the mechanism that implements allocations is not an opt...

Evaluation of equilibrium constants by affinity chromatography.

Theoretical expressions are derived for affinity chromatography of systems comprising an acceptor A with one binding site for attachment to a functional group X on the column matrix and one site for interaction with a small ligand B that specifically affects its elution. From a general relationship covering all possible interactions between A, B and X simpler expressions are derived for affinit...

Determination of Equilibrium Constants using NMR Spectrscopy

In this laboratory exercise we will measure a chemical equilibrium constant using key proton signals in a Nuclear Magnetic Resonance (NMR) spectrum. Those doing the “traditional” P Chem experiments will examine a keto-enol tautomerism, while those doing the “biophysical” experiments will look at the cis-trans equilibrium for a peptide bond. In each case, the relative concentration of the equili...

Determination of Equilibrium Constants using NMR Spectrscopy

In this laboratory exercise we will measure the Equilibrium Constant Kc for the keto-enol tautomerism of two -diketones and two -diketoesters. This will be accomplished by measuring the signal strength of key protons in the Nuclear Magnetic Resonance (NMR) spectrum of the equilibrium system. The influence of the solvent on the equilibrium position will be examined by considering the measured ...
