Tunable polarization converter based on one-dimensional graphene metasurfaces

We introduce a new metasurface structure for controlling the polarization of light by leveraging a well-harmonized combination of graphene and dielectric. The proposed metasurface is composed of an array of rectangular pillars laterally sandwiched by ribbo ...

The cyclo-β-tetrapeptide (β-HPhe-β-HThr-β-HLys-β-HTrp): synthesis, NMR structure in methanol solution, and affinity for human somatostatin receptors

Karl Gademann

The known solid-state structure of cyclo(β-HAla)4 was used to model the structure of the cyclo-β-tetrapeptide (β-HPhe-β-HThr-β-HLys-β-HTrp) as a prospective somatostatin mimic. The synthesis started with the N-protected natural amino acids Boc-Phe-OH, Boc- ...
