A “foldamer” is an artificial oligomeric molecule with a regular secondary or tertiary structure consisting of various building blocks. “stapled peptide” peptide stabilized structures, in particular, helical structures by intramolecular covalent side-chain cross-linking. Helical foldamers and stapled peptides are potential drug candidates that can target protein-protein interactions because the...

We provide an overview of the helical magnetic structures in microwires. Having analyzed experimental data describing behavior microwires since 1990s, we found indirect evidence existence various types structures. Purposeful research has allowed us to discover spiral structure as one most unusual A comparison with another type structure—elliptical—was carried out. In analysis, emphasis was plac...

─ Normal mode helical antennas are widely used for RFID and mobile communications applications due to their relatively small size and omni-directional radiation pattern. However, their highly curved geometry can make the design and analysis of helical antennas that are part of larger complex structures quite difficult. A simplified model is proposed that replaces the curved helix with straight ...

Pt(ii) phenylbipyridine complexes possessing bis(phenylisoxazolyl)phenylacetylene ligands self-assembled to form stacked aggregates via Pt-Pt, π-π stacking, and dipole-dipole interactions. The assembled structures were influenced by the solvent properties. Non-helical assemblies found in chloroform displayed metal-metal-to-ligand charge transfer absorption and emission, whereas helical assembli...
