Sub-micron Polymer-Zeolitic Imidazolate Framework Layered Hybrids via Controlled Chemical Transformation of Naked ZnO Nanocrystal Films

Here we show that sub-micron coatings of zeolitic imidazolate frameworks (ZIFs) and even ZIF-ZIF bilayers can be grown directly on polymers of intrinsic microporosity from zinc oxide (ZnO) nanocrystal precursor films, yielding a new class of all-microporou ...

Passivation of ZnO Nanowire Guests and 3D Inverse Opal Host Photoanodes for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Nicolas Tétreault, Thomas Moehl, Aravind Kumar Chandiran, Philippe Pierre Labouchère

A hierarchical host-guest nanostructured photoanode is reported for dye-sensitized solar cells. It is composed of ZnO nanowires grown in situ into the macropores of a 3D ZnO inverse opal structure, which acts both as a seed layer and as a conductive backbo ...

Comparative STM studies of mixed ligand monolayers on gold nanoparticles in air and in 1-phenyloctane

Francesco Stellacci, Javier Reguera Gomez, Shun Zhao

Scanning tunnelling microscopy (STM) studies have found stripe-like domains on gold nanoparticles (NPs) coated with certain binary mixtures of ligand molecules. The majority of these NPs' properties have been investigated for particles in solvents. Yet, mo ...

Quantum-Confined ZnO Nanoshell Photoanodes for Mesoscopic Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Mohammad Ibrahim Dar, Chenyi Yi, Aswani Yella, Aravind Kumar Chandiran, Mojtaba Abdi Jalebi

We present a photoanode for dye-sensitized solar cell (DSC) based on ZnO nanoshell deposited by atomic layer deposition at 150°C, on a mesoporous insulating template. An ultrathin layer of ZnO between 3 and 6 nm, which exhibits quantum confinement effect, ...

Flexible, low-temperature, solution processed ZnO-based perovskite solid state solar cells

Michael Graetzel, Nripan Mathews

A ZnO compact layer formed by electrodeposition and ZnO nanorods grown by chemical bath deposition (CBD) allow the processing of low-temperature, solution based and flexible solid state perovskite CH3NH3PbI3 solar cells. Conversion efficiencies of 8.90% we ...

Mesoporous Silica Nanoparticles Loaded with Surfactant: Low Temperature Magic Angle Spinning C-13 and Si-29 NMR Enhanced by Dynamic Nuclear Polarization

Geoffrey Bodenhausen, Diego Carnevale

We show that dynamic nuclear polarization (DNP) can be used to enhance NMR signals of C-13 and Si-29 nuclei located in mesoporous organic/inorganic hybrid materials, at several hundreds of nanometers from stable radicals (TOTAPOL) trapped in the surroundin ...

Ethanol-enriched low-pressure chemical vapor deposition ZnO bilayers: Properties and growth-A potential electrode for thin film solar cells

Christophe Ballif, Sylvain Nicolay, Grégory Bugnon, Laura Ding

Ethanol is used as a precursor during the growth of zinc oxide (ZnO) by low-pressure chemical vapor deposition (LPCVD). By adding ethanol, the surface of the deposited ZnO layer is flattened and its roughness is decreased about sevenfold. The layers become ...

The Presence of Ultralow Densities of Nanocrystallites in Amorphous Poly(lactic acid) Microspheres

Sylvie Roke, Hilton Barbosa De Aguiar

Ultralow densities of crystalline nanospheres have been detected in amorphous polymer microspheres by utilizing the unique sensitivity of second-order nonlinear optical techniques to anisotropy. Vibrational sum frequency scattering (SFS) and X-ray diffract ...

Ordered Arrays of Size-Selected Oxide Nanoparticles

Luca Gragnaniello

A bottom-up approach to produce a long-range ordered superlattice of monodisperse and isomorphic metal-oxide nanoparticles (NP) supported onto an oxide substrate is demonstrated. The synthetic strategy consists of self-assembling metallic NP on an ultrathi ...
