This paper is devoted to illustrate the setting up of a RFbased streak Camera (RFC). Beam deflection was accomplished by replacing the standard deflecting plates of a conventional streak camera (SC) by a RF cavity located just after the accelerating optics. The magnetic field in the cavity imparts a transverse force to incoming electrons, whose direction depends on the time at which each indivi...

Mass transfer data were obtained in circular conduit using an electrochemical technique with a potassium ferri-ferro cyanide couple. In circular conduit coaxially placed entry region equilateral triangular plate was used as turbulence promoter. The study comprised of evaluation of mass transfer rates at the outer wall of the electrochemical cell. Mass transfer coefficients were evaluated from t...

Surface plasmon excitation that is due to a single or a structured circular aperture in a flat metallic screen is investigated theoretically and numerically with a view to enhancing the electric field close to the metallic surface. A systematic study of the homogeneous solution of the electromagnetic scattering problem is made with cylindrical coordinates, expanding Maxwell equations on a Fouri...

Methods for solving two-dimensional scattering problems using conformal mappings are investigated. It is shown that their convergence relies on a mapped form of the Rayleigh hypothesis. It is concluded that methods based on conformal mappings offer no advantages over established methods in which the scattered field is expanded as a series of circular-cylindrical outgoing wavefunctions.

We report herein the first small molecule based self-assembled fluorescent trinuclear Zn(II) supramolecular cylindrical motif as a structural and functional model of the active site of P1 nuclease. The DNA binding of the same was investigated through UV-Vis, fluorescence and circular dichroism studies.

Abstract Superpositions of paraxial laser beam modes to generate atom-optical lenses based on the optical dipole force are investigated theoretically. Thin, wide, parabolic, cylindrical and circular atom lenses with numerical apertures much greater than those reported in the literature to date can be synthesized. This superposition approach promises to make high quality atom beam imaging and na...
