Abstract

Fuel cells used for transport applications hold polymer membranes as a key element. Their efficiency can be significantly increased if structured ion channels are implemented at the molecular level into the proton‐conducting membrane. New functional molecules with selective affinity for ionomers are needed to obtain such a membrane design. This study presents a method to screen for selective peptide binders to perfluorinated sulfonic acid ionomers, e.g., Nafion using ultra‐high density peptide arrays with a spot size of up to 30 µm. First, the ionomer dispersion is incubated with the peptide chip containing 56014 randomly chosen 6‐mer peptides. Afterward, the peptide chip is washed. The peptide WIWHCW with the helix structure is identified as a selective binder to Nafion. The invariant amino acids responsible for binding are also determined using a peptide chip approach. The specific binding pocket of WIWHCW is formed by histidine and tryptophan. Its dissociation constant to the ionomer is measured at ≈140 µM. [ABSTRACT FROM AUTHOR]

7. The uptake and metabolism of [32P]pyrophosphate by mouse calvaria in vitro

Author

Jung, André, Bisaz, Sylvia, Gebauer, Urs, Russell, Robert Graham G., Morgan, David Brian, and Fleisch, Herbert

Abstract

In order to study the uptake and metabolism of PPi by bone, 32PPi was added to the medium surrounding explanted mouse calvaria maintained in organ culture. Most of the PPi was hydrolysed during incubation, but there was a measurable entry of intact PPi into bone. When 32Pi was added to the medium, synthesis of PPi and organic phosphates from Pi was observed in bone. There was no detectable passage of PPi from bone into the medium. These results are discussed in terms of two models of pyrophosphate hydrolysis and exchange. Some quantitative estimates about the fate of PPi in bone were made.
