Infinite pleated -sheet formed by the -hairpin Boc- -Phe- -Phe-D-Pro-Gly- -Phe- -Phe-OMe

A -hairpin conformation and extended -pleated sheet assembly have been characterized by single crystal x-ray diffraction for the synthetic peptide t-butoxycarbonyl— -Phe-Phe-D-Pro-GlyPhe-Phe-methyl ester [ -Phe: (S)3 homophenylalanine]. The centrally located D-Pro-Gly segment nucleates a chain reversal in a type II -turn conformation. Two intramolecular cross-strand hydrogen bonds stabilize the...

Superstatistics, thermodynamics, and temperature variations

A thermodynamic-like formalism is developed for superstatistical systems based on conditional entropies. This theory takes into account large-scale temperature variations for systems in nonequilibrium stationary states. Ordinary thermodynamics is recovered as a special case of the present theory, and corrections to it can be systematically evaluated. A generalization of Einstein’s relation for ...

Angular Temperature Variations in a Wall-Cooled

The signijkance of the statistical character of wall-cooled packed-bed reactors was studied by measuring angular temperature variations, which result @om the random nature of the packing. These are neglected in present-day mathematical models designed to describe the reactor behavior. The amplitude of these variations was determined experimentally as a function of the mass flux and the position...

The Phe-Phe Motif for Peptide Self-Assembly in Nanomedicine.

Since its discovery, the Phe-Phe motif has gained in popularity as a minimalist building block to drive the self-assembly of short peptides and their analogues into nanostructures and hydrogels. Molecules based on the Phe-Phe motif have found a range of applications in nanomedicine, from drug delivery and biomaterials to new therapeutic paradigms. Here we discuss the various production methods ...
