We present an overview of recent investigations of photopolymerizable nanocomposite photonic materials in which, thanks to their high degree of material selectivity, recorded volume gratings possess high refractive index modulation amplitude and high mechanical/thermal stability at the same time, providing versatile applications in light and neutron optics. We discuss the mechanism of grating f...

TiO2 nanoparticle (NP)/ITO nanowire (NW) nanocomposites for use as photoelectrode materials were fabricated to improve the charge collection efficiency in solid state dye sensitized solar cells (ss-DSSCs). The average current density for ss-DSSCs containing TiO2 NP/ITO NW arrays was 7.2 mA cm(-2) that was 98% higher than that for the conventional TiO2 NP ss-DSSCs. The intensity modulated photoc...

We show that post-synthetic small-molecule intercalation can significantly reduce the electronic confinement of 2D hybrid perovskites. Using a combined experimental and theoretical approach, we explain structural, optical, and electronic effects of intercalating highly polarizable molecules in layered perovskites designed to stabilize the intercalants. Polarizable molecules in the organic layer...

25 ABSTRACT: In this work the synthesis of polyaniline/chitosan/functionalized singlewalled carbon nanotube nanocomposite is carried out. For this purpose, single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. In other step, aniline monomers and chitosan were polymerized in the presence of Iron (III) Ch...

Atomic layer deposition (ALD) has been widely reported as a novel method for thin film encapsulation (TFE) of organic light-emitting diodes and organic photovoltaic cells. Both organic and inorganic thin films can be deposited by ALD with a variety of precursors. In this work, the performances of Al2O3 thin films and Al2O3/alucone hybrid films have been investigated. The samples with a 50 nm Al...

A unique organic-inorganic hybrid compound has been separated under hydrothermal condition, which is constructed from a three-dimensional second metal-organic subunit and entrapped hexadecavanadate clusters.

The most effective means to protect against bacterial invasion and to reduce the risk of healthcare-associated infections are antibacterial components synthesis. In this study, a novel process for the synthesis of organic-inorganic hybrid coatings containing silver nanoparticles is presented. Silver nanoparticles and polymer formation proceeds simultaneously through the in situ photoreduction o...

We fabricated sub-wavelength periodic structures by thermal nano-imprinting using our original functionally modified inorganic–organic hybrid materials. The fabricated structures exhibited excellent uniformity and surface smoothness over a large imprinted area. In addition, optical transmittance is more than 90% within visible wavelength regions after heat treatment for 2 h at 300 C. These nano...

proton exchange membrane fuel cells (pemfcs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. in this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/la2ce2o7 (pva-lc) with the aim of increasing the water uptake and proton conductivity. glutaraldehyde (ga) was used as cross linking agent ...

A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous solution instead of an organic solvent.
