• Increase in the β-Sheet Character of an Amyloidogenic Peptide upon Adsorption onto Gold and Silver Surfaces
  • Increase in the β-Sheet Character of an Amyloidogenic Peptide upon Adsorption onto Gold and Silver Surfaces

    All on the surface? Fibrillation of amyloidogenic peptides is believed to be the cause of neurodegenerative diseases. Atomistic molecular dynamics simulations are used to show that adsorption of Aβ25–35 onto silver and gold surfaces catalyzes the formation of β-sheet-rich conformations of Aβ25–35. This study suggests that the interactions at the nano–bio interface prompts the toxicity of this peptide by altering its conformational state.

  • Pentatwinned Cu Nanowires with Ultrathin Diameters below 20 nm and Their Use as Templates for the Synthesis of Au-Based Nanotubes
  • Pentatwinned Cu Nanowires with Ultrathin Diameters below 20 nm and Their Use as Templates for the Synthesis of Au-Based Nanotubes

    When the oxygen on the two ends of Cu nanowires was removed under an argon atmosphere, the axial growth was accelerated, yielding thinner Cu nanowires (below 20 nm). In the meantime, the argon atmosphere could suppress oxidative etching, improving the yield and purity of the Cu nanowires.

  • Selective Hydrogenation of Nitriles to Primary Amines by using a Cobalt Phosphine Catalyst
  • Selective Hydrogenation of Nitriles to Primary Amines by using a Cobalt Phosphine Catalyst

    Cobalt catalyzes it: A general procedure for the selective hydrogenation of (hetero)aromatic or aliphatic nitriles catalyzed by a cobalt-based system is described. A wide range of primary amines are synthesized in 61–99 % yield. Use of the tetradentate ligand tris[2-(dicyclohexylphosphino)ethyl]phosphine is key for the activity of the system.

  • Intramolecular Triple Cyclization Strategy for Sila- and Oxa-Analogues of Truxene with Long-Lived Phosphorescence
  • Intramolecular Triple Cyclization Strategy for Sila- and Oxa-Analogues of Truxene with Long-Lived Phosphorescence

    Trisilatruxene and trioxatruxene, respective sila- and oxa-analogues of truxene, were synthesized by employing a new intramolecular triple cyclization strategy. These compounds together with hexamethyltruxene display long-lived phosphorescence with the lifetime of 4.4–16.4 s at a low temperature. The long lifetimes are attributable to the symmetry-forbidden T1[RIGHTWARDS ARROW]S0 transitions, being essentially linked with the C3-symmetric structures.

  • Pore Topology Effects in Positron Annihilation Spectroscopy of Zeolites

    The behavior of ortho-positronium in zeolitic materials is highly sensitive to the micropore topology. An atomic model is developed based on the Tao–Eldrup potential and the crystallographic structure to calculate the inherent distribution and lifetime of ortho-positronium for a given framework type.

  • Photocatalytic Trifluoromethylthiolation of Aromatic Alkenes Associated with Hydroxylation and Alkoxylation

    Activator-free: An additive-free photoredox-catalyzed trifluoromethylthiolation of aromatic alkenes has been developed. Trifluoromethanesulfenyl radical (.SCF3) is efficiently generated from a photocatalyst and an electrophilic triflouromethylthiolating reagent. This photoredox system induces a regioselective oxytrifluoromethylthiolation of carbon–carbon double bonds through catalytic processes without any activator.
