  • Zero reflection and transmission in graded index media 

    King, CG; Horsley, SAR; Philbin, TG (Springer Verlag, 2016-05-06)
    Graded index media whose electric susceptibility satisfies the spatial Kramers-Kronig relations are known to be one-way reflectionless to electromagnetic radiation, for all angles of incidence. We demonstrate how a family ...
  • Zero-energy states in graphene quantum dots and rings 

    Downing, C.A.; Stone, D.A.; Portnoi, M.E. (2011)
    We present exact analytical zero-energy solutions for a class of smooth-decaying potentials, showing that the full confinement of charge carriers in electrostatic potentials in graphene quantum dots and rings is indeed ...
  • Zigzag-Shaped Superlattices on the Basis of Graphene Nanoribbons: Structure and Electronic Properties 

    Saroka, VA; Batrakov, KG (Springer Verlag, 2016-09-08)
    The paper focuses on superlattices consisting of two coplanar fragments of one-layer graphene nanoribbons that have different width and are connected at an angle. Classification of such superlattices was carried out; their ...
  • α-Tocopherols modify the membrane dipole potential leading to modulation of ligand binding by P-glycoprotein 

    Davis, Sterenn; Davis, Benjamin M.; Richens, Joanna L.; Vere, Kelly-Ann; Petrov, Peter G.; Winlove, C. Peter; O'Shea, Paul (American Society for Biochemistry and Molecular Biology, 2015-08)
    α-Tocopherol (vitamin E) has attracted considerable attention as a potential protective or palliative agent. In vitro, its free radical-scavenging antioxidant action has been widely demonstrated. In vivo, however, vitamin ...
