The metallic Co catalyst for the Fischer-Tropsch reaction is prepared by reduction of Co salts impregnating microporous silica. The average size of the metallic Co clusters is determined from the average number of neighbours deduced from Co K-edge EXAFS of catalyst samples. A model EXAFS signal constructed from the scattering paths of Co metal fcc lattice with lengths up to 5 A is calibrated on...

Drug bearing nano-shells that can be utilized for targeted drug delivery have been shown to enhance the therapeutic index by increasing dug concentration in diseased tissue and reducing toxicity normal tissue. The controllability of shell size provides predictability measure amount payload per which improves administration dose. FDA approved different formulations clinical use metastatic recurr...

We demonstrate a method for fabricating a variety of nanostructured metallic thin films by using one simple approach based on the use of anodic aluminum oxide (AAO) membrane as masking template. Highly-ordered large-area metallic nanoporeor nanotip-arrays (e.g., Ni, Ag, Au), with various sizes and shapes, were deposited onto AAO membranes through e-beam evaporation. Free standing nano-patterned...

We present here the design of nano-inclusions made of properly arranged collections of plasmonic metallic nano-particles that may exhibit a resonant magnetic dipole collective response in the visible domain. When such inclusions are embedded in a host medium, they may provide metamaterials with negative effective permeability at optical frequencies. We also show how the same inclusions may prov...

An optical dipole nano-antenna can be constructed by placing a sub-wavelength dielectric (e.g., air) gap between two metallic regions. For typical applications using light in the infrared region, the gap width is generally in the range between 50 and 100 nm. Owing to the close proximity of the electrodes, these antennas can generate very intense electric fields that can be used to excite nonlin...

In the last several decades, the electrochemical synthesis and became the enabling fabrication methods electrodeposition behind the train of hi-tech enterprise [1,2]. There are many examples where electrochemical synthesis provides convenient if not “ approach to deliver the desired structures, materials or catalytic surfaces. In recent years, the the only” scientific community has witnessed th...
