Electrochemical Synthesis of Bismuth Particles: Tuning Particle Shape through Substrate Type within a Narrow Potential Window
Bismuth (Bi) electrodeposition was studied on Si/Ti/Au, FTO-, and ITO-coated glasses from acidic nitrate solutions with and without gluconate within a narrow potential window (ΔE = 80 mV). This potential range was sufficient to observe a change in particle shape, from polyhedrons (including hexagons) to dendrites, the trend being slightly different depending on substrate activity. In all cases,...
متن کاملChromatic tuning of contour-shape mechanisms revealed through the shape-frequency and shape-amplitude after-effects
We investigated whether contour-shape processing mechanisms are selective for color direction using the shape-frequency and shape-amplitude after-effects, or SFAE and SAAE [Gheorghiu, E. & Kingdom, F. A. A. (2006). Luminance-contrast properties of contour-shape processing revealed through the shape-frequency after-effect. Vision Research, 46(21), 3603-3615. Gheorghiu, E. & Kingdom, F. A. A. (20...
متن کاملTuning Charge Transfer in Ion-Surface Collisions at Hyperthermal Energies.
Charge exchange in ion-surface collisions may be influenced by surface adsorbates to alter the charge state of the scattered projectiles. We show here that the positive-ion yield, observed during ion scattering on metal surfaces at low incident energies, is greatly enhanced by adsorbing electronegative species onto the surface. Specifically, when beams of N(+) and O(+) ions are scattered off of...
متن کاملTuning cell surface charge in E. coli with conjugated oligoelectrolytes
Cationic conjugated oligoelectrolytes (COEs) varying in length and structural features are compared with respect to their association with E. coli and their effect on cell surface charge as determined by zeta potential measurements. Regardless of structural features, at high staining concentrations COEs with longer molecular dimensions associate less, but neutralize the negative surface charge ...
متن کاملOptimal tuning of lasing modes through collective particle resonance
One of the current challenges in laser optics is to take advantage of the resonant modes within particles to obtain high-quality microcavities with low threshold. We present a study of the effect that the internal resonances of individual particles have on the emitted intensity, and demonstrate how optimal tuning of the size and separation of the particles can enhance the quality factor by more...
