Synthesis and Structure-Property Correlation in Shape-Controlled ZnO Nanoparticles Prepared by Chemical Vapor Synthesis and their Application in Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Peter Chen

Here, the large scale synthesis of nanocrystalline ZnO spheres and tetrapods in the size range of 8-40 nm by chemical vapor synthesis using zinc metal as precursor is described. A detailed study of the effect of experimental parameters on the morphology an ...

A facile strategy for preparation of fluorescent SWNT complexes with high quantum yields based on ion exchange

Paul Joseph Dyson, Zhaofu Fei

The fluorescent imidazolium salt (1,3-bis(9-anthracenylmethyl)imidazolium chloride, [bamim]Cl) has been grafted onto the surfaces of single-walled carbon nanotubes (SWNTs) using an ion exchange strategy based on metathesis of the K+ ion in CO2K derivatized ...

Influence of process pressure on local facesheet instability for ultralight sandwich structures

Jan-Anders Edvin Maansson, Yves Leterrier, Samuel Stutz

The skin wrinkling phenomenon was investigated in case of ultralight sandwich structures with honeycomb core manufactured by one shot vacuum bag processing. A relation between process pressure and compressive strength of the skin was established. ...

Electroactive nanowells for spectrographic fluidic memory

Demetri Psaltis

Current optical storage devices such as DVDs have their read/write capabilities fundamentally restricted by the diffraction limit of light. We present an optofluidic architecture for storing cocktails of colloidal quantum dots in electroactive nanowell str ...

Color images visible under UV light

Roger Hersch, Sylvain Chosson

The present contribution aims at creating color images printed with fluorescent inks that are only visible under UV light. The considered fluorescent inks absorb light in the UV wavelength range and reemit part of it in the visible wavelength range. In con ...

Photorheology of Fast UV Curing Multifunctional Acrylates

Jan-Anders Edvin Maansson, Yves Leterrier, Jean-Marc Vesin, Lars Schmidt

The fast photopolymerization of different multifunctionalacrylates was analyzed by means of photorheology.The materials studied included a penta/hexaacrylatemonomer and two different acrylated hyperbranchedpolymers. The sensitivity of the commercial rheome ...
