Bulk Heterojunction Organic-Inorganic Photovoltaic Cell Based on Doped Silicon Nanowires
A bulk heterojunction organic-inorganic photovoltaic cell was fabricated by growing doped n-type silicon nanowires on an n+ silicon substrate. A p-type organic semiconductor (P3HT) was then coated over the nanowires. The device was completed by [...]
Molecular Building Blocks for Efficient Solid State Lighting
General illumination consumes 22% of the electricity generated in the U.S. This huge proportion is partly due to the ubiquity of artificial lighting but also the inefficiency of converting electrical energy to light. Incandescent lightbulbs [...]
Dynamics of Water in Nafion Fuel Cell Membranes: the Effects of
The complex environment experienced by water molecules in the hydrophilic channels of Nafion membranes is studied by ultrafast infrared pump-probe spectroscopy. A wavelength dependent study of the vibrational lifetime of the O-D stretch of dilute [...]
Determination of Pore Size Distribution of Nafion/Sulfated beta-Cyclodextrin
Direct methanol fuel cells are promising candidates for portable power sources and transport applications. One of the critical problems hindering the commercialization of DMFCs is high methanol permeation rate across proton-exchange membranes. In this study, [...]
Hydroxyapatite-imidazole-polymer composite films as a proton conductor under no humidified condition
We prepared the proton conduction system, hydroxyapatite (HAp)-imidazole (Im)-polymer composite films and investigated their structure, conduction behavior and mechanical properties. HAp particles used in our investigation were prepared with two different ways, a-HAp and n-HAp. [...]
Block Copolymer Directed Nanocomposites for Fuel Cell Applications
Block copolymers [1,2] and ionomers comprising fluoro/non-fluoro segments have significant potential applications in the field of fuel cell. However, they are very difficult to synthesize; because fluoro monomers are not amenable to living ionic polymerization [...]
Microbial fuel cell
Polymer electrolyte fuel cells, PE-FC, use hydrogen or methanol as fuel. Water soluble organic compounds, like starch, glucose, acetates, can not serve as fuel because of limited catalytic activity of common metal catalysts. Opposite to [...]
Synthesis of visible light active nanocrystalline bismuth oxide based photocatalysts
Akurati K.K., Vital A., Reifler F., Ritter A., Graule T., Swiss federal laboratories for materials science & technology, EMPA, CH
Photocatalysis phenomenon has attracted considerable interest in recent years because of its usage in water purification, environmental cleaning, solar energy conversion and generation of alternative energy resources. To date, TiO2 has undoubtedly proven to be [...]
