The leading-order far-field scattered flow produced by a particle in a parallel-wall channel under creeping-flow conditions has a form of the parabolic velocity field driven by a two-dimensional dipolar pressure distribution. We show that in a system of hydrodynamically interacting particles, the pressure dipoles contribute to the macroscopic suspension flow in a similar way as the induced elec...

We explore the limits of modifying metal work functions with large molecular dipoles by systematically increasing the dipole moment of archetype donor-acceptor molecules in self-assembled monolayers on gold. Contrary to intuition, we find that enhancing the dipoles leads to a reduction of the adsorption-induced change of the work function. Using atomistic simulations, we show that large dipoles...

Metallic rods with submicron diameters that contain disklike ferromagnetic sections self-assemble into highly stable, hexagonally close-packed arrays of rods. The rods were fabricated by electrodeposition in porous alumina membranes and comprised alternating sections of gold and nickel. The thicknesses of the ferromagnetic nickel sections were approximately one-half the diameter of the rods (40...

Introduction: The periodic moment method, developed by Munk and colleagues at Ohio State University, is one of the most important and powerful contributions to numerical analysis of antenna arrays, frequency selective surfaces and gratings. PMM, with its extensions and improvements, can handle multiple dielectric layers and slotted metallic sheets, with wires partially inside a dielectric or ai...

Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...

Abstract Natural materials typically interact weakly with the magnetic component of light which greatly limits their applications. This has led to development artificial metamaterials and metasurfaces. However, natural atoms, where only electric dipole transitions are relevant at optical frequencies, can cooperatively respond form collective excitations strong magnetic, as well electric, intera...

Three-dimensional geoelectrical surveys are widely used to map the subsurface in areas with complex geology. Field survey methods using offset pole–dipole and dipole–dipole arrays have been proposed large efficiently. However, it has found that negative apparent resistivity values sometimes encountered contrasts, particularly when offsets between current electrodes potential dipoles used. The v...

theoretical investigations on the characteristics of the nuclear quadrupole resonance and the influence of the magnetic effect on it have been carried out. the magnetic dipole effect on the quadrupole resonance for the two spins i and i with different values oft) and e has been studied. the energy levels and their transition probabilities are presented with their corresponding spectra. the firs...
