Plasmonically Enhanced Thin-Film Amorphous Silicon Solar Cells

Sonsalla T., Louisiana Tech University, US

Hydrogenated amorphous silicon (a-Si:H) can absorb the visible part of the solar spectrum better than crystalline silicon. For this reason, a-Si:H solar cells can be much thinner than crystalline silicon solar cells. Thinner cells reduce [...]

Synthesis and Characterization of Copper-Copper oxide nanofluids in the confinement regime

Babukutty B., Parakkal F., Bhalero G.M., Nair S.S., Central University of kerala, IN

Abstract: Copper oxide shelled copper nanofluids are synthesized with surfactant trioctylphosphine oxide (TOPO) using sulphates precursors. The fluids were structurally characterised by X-ray Diffraction (XRD). Surface and morphological characterization are carried out by Scanning Electron [...]

Differentiating electro-catalytic reaction of hydride with respect to a non-Pt catalyst morphology based on first-principles: extended surfaces versus nanoparticles

Sison Escaño M.C., Lacdao Arevalo R., Kasai H., University of Fukui, JP

One of the attractive hydride compounds is the borohydride which exhibits high hydrogen content in NaBH4 form (~10.6 wt%). Thus, significant number of experimental research have been devoted to investigate its applicability as a hydrogen [...]

New ripening mechanism for silver and gold nanorods in aqueous solution

Segets D., Damm C., Yang G., Spiecker E., Peukert W., Friedrich-Alexander University, DE

In the last years an increasing number of publications addressed the relationship between particle shape and the electro-optical product properties. Especially anisotropic metal particles e.g. gold or silver were found to be promising candidates as [...]

Using Chondroitin Sulfate to Synthesize Nanoparticles

Vercruysse K.P., Williams A., Ivory D., Johnson B., Dixon R.D., Tran M.T., Moore J.T., Tennessee State University, US

We provide evidence that chondroitin sulfate (CS), a member of the glycosaminoglycan (GAG) family of polysaccharides found in the extracellular matrix of all higher order species, can be used as a matrix to generate nanosized [...]

Modified Nanoparticle Films for Transmission Plasmon Biosensing

Bonroy K., Frederix F., Reekmans G., Jans H., Jans K., Jans H., Jans K., Van de Broek B., De Palma R., Borghs G., IMEC, BE

The principle of the Transmission Plasmon Biosensor is based on LSPR of metal nanoparticles attached to a transparent substrate. When the analyte of interest binds to the bioreceptors immobilized onto these nanoparticles, the absorption properties [...]

Surface Plasmon Resonances of Metal Polyhedral Nanoparticles

González A.L., Noguez C., UNAM, MX

In this work, we show that it is possible to elucidate among different polyhedral shapes of silver nanoparticles of less than 10 nm, by studying their surface plasmon resonances. When a particle is excited by [...]
