Strongly Interacting Plasmon Nanoparticle Pairs: From Dipole−Dipole Interaction to Conductively Coupled Regime
We have investigated the optical response of periodic arrays of metallic (gold) nanoparticles composed of a pair of particles on each lattice site. By varying the interparticle separation within the… Expand

Thin films of polyelectrolyte/J aggregate dye bilayers inserted in an optical microcavity enable the cavity quantum electrodynamic strong coupling limit to be reached at room temperature with a coupling strength (Rabi splitting) of 265 +/- 15 meV. Expand
Enhanced optical output power of green light-emitting diodes by surface plasmon of gold nanoparticles
We demonstrate the surface plasmon (SP) enhanced green light-emitting diodes (LEDs). The Au nanoparticles were embedded in the p-GaN of LEDs. The photoluminescence and electroluminescence… Expand
The Effect of Fabrication Conditions for GDC Buffer Layer on Electrochemical Performance of Solid Oxide Fuel Cells
A Gd-doped ceria (GDC) buffer layer is required between a conventional yttria-stabilized zirconia (YSZ) electrolyte and a La-Sr-Co-Fe-O3 (LSCF) cathode to prevent their chemical reaction. In this… Expand

Tuning the surface plasmon polariton resonance to the quantum dot exciton emission band results in an enhancement of up to approximately 50-fold in the overall fluorescence efficiency, in a design where each Ag nanoparticle is interconnected by a continuous Ag thin film. Expand
Removal of hardness ions from tap water using electromembrane processes
Abstract Performances of electromembrane systems were investigated for removal of the hardness materials in a tap water. Six cells of ED, EDR, and EDIR systems with an electrode area of 12.5cm x 8.0… Expand

Abstract The surface modified lithium electrode is prepared by coating an ionic conductive poly(vinylene carbonate-co-acrylonitrile) layer as a solid electrolyte interphase on lithium metal. The thin… Expand
A study on stack configuration of continuous electrodeionization for removal of heavy metal ions from the primary coolant of a nuclear power plant.
The feasibility of the CEDI operation for the removal of heavy metals at a very low concentration is demonstrated, and the precipitation of metal ions is prevented. Expand
Reversible Macroscopic Alignment of Ag Nanowires
