Objective(s): NiTi is known as the most important material for manufacturing implants and medical devises duo to its shape memory and superelasticity properties, high energy damping, and high corrosion resistance. Methods: In this project, the possibility of producing nanostructured NiTi implant with high porosity was investigated. For reaching to the nan...

Adv. Mater. 2010, 22, 2329–2332 2010 WILEY-VCH Verlag G Since the advent of dye-sensitized solar cells (DSCs), which have achieved 11% of power conversion efficiency (PCE) in TiO2-based photoelectrodes, a lot of efforts have been devoted to make low-cost, light-weight, high-performance photovoltaic devices. Nanostructured metal oxides are one of key factors in determining the PCE of DSCs, becau...

In this project, versatile processing techniques are established for improving the internal and external quantum efficiencies of Si MOSLEDs via the detuning the size and density of high-aspect-ration Si nano-rod and buried Si nanospheres. A rapid thermal annealing synthesis of metallic nanodot array is realized to control the size and density control of metallic nanodots as an etching mask for ...

Tremendous insights into the mechanisms for electron transfer have been gained over the last 15 years by studying donorspacer-acceptor model systems of varying complexity.1 Important and classic experiments involving redox active molecules separated by hydrocarbon,2,3 peptidic,4 protein,5 and DNA6 spacers, have thoroughly revealed the distance dependence for electrontransfer processes in fluid ...

We investigate the PL characteristics of the equivalent-size controlled Si-QDs by employing the nano-porous AAO membrane as the template for growing Si-rich SiOx nano-rods to achieve the spatially confined synthesis of Si-QD. The ultra-bright PL can be emitted from the SiOx nano-rod in nano-porous AAO membrane. In addition, we preliminarily demonstrate the in-situ high-temperature synthesis of ...

Nonaqueous potassium-ion batteries have emerged as possible lowcost alternatives to Li-ion batteries for large-scale energy storage, owing to their ability to use graphitic carbon as the negative electrode. Positive electrode materials remain a challenge. Here, we report control of the crystal dimensions of the Prussian white hexacyanoferrate (HCF), K1.7Fe[Fe(CN)6]0.9, using solution chemistry ...
