    Mn-porphyrins in a four-helix bundle participate in photo-induced electron transfer with a bacterial reaction center

    Hybrid complexes incorporating synthetic Mn-porphyrins into an artificial four-helix bundle domain of bacterial reaction centers created a system to investigate new electron transfer pathways. The reactions we...

    Quasicrystalline coatings: Thermal evolution of structure and properties

    Quasicrystals (QCs) are known to exhibit unique properties as a result of their unique quasiperiodic structure. Real quasicrystalline (QC) materials, however, may exhibit complex phase structures, and as a con...
