The synthesis of environmentally friendly-based chemicals such as solvent-free continues to be developed. A critical precursor in chemical is benzoic acid. This research developed a method by utilizing TiO2 nanomaterials with different morphologies photocatalysts, namely nanoparticles (NPs) and nanowires (NWs). Titanium (IV) oxide morphology was synthesized hydrothermal under alkaline condition...
The effect of length variation on the magnetic properties of NiFe alloy nanowires electrodeposited into the alumina template was investigated. The diameter (45±2.5 nm) and length (~ 1.9, 7.12, 8.3, 9.5 and 13.3 µm) of the nanowires were estimated from scanning electron microscopy images. Energy dispersive spectroscopy results showed Ni3Fe7 composition of the alloy nanowire...
As an effective transient thermal characterization technique, the transient electrothermal (TET) technique features a capability of measuring micro∕nanoscale samples of diverse electrical conducting natures. In this work, single anatase titanium dioxide (TiO(2)) nanowires fabricated using the electrospinning method are characterized using the TET technique. Time-dependent nonlinear effect is ob...
The interest in dye-sensitized solar cells has increased due to reduced energy sources and higher energy production costs. For the most part, titania (TiO2) has been the material of choice for dye-sensitized solar cells and so far have shown to exhibit the highest overall light conversion efficiency ∼ 11 %. However, zinc oxide (ZnO) has recently been explored as an alternative material in dye-s...
The lithium insertion behavior of nanoparticle (3-D) and nanosheet (2D) architectures of TiO2(B) is quite different, as observed by differential capacity plots derived from galvanostatic charging/discharge experiments. DFT+U calculations show unique lithiation mechanisms for the different nanoarchitectures. For TiO2(B) nanoparticles, A2 sites near equatorial TiO6 octahedra are filled first, fol...
coni nanowires were deposited by pulsed electrodeposition technique into porous alumina templates. the effect of off time between pulses (toff) and reductive/oxidative time (treduc/oxid) on the microstructure and magnetic properties of the coni nanowires were investigated. maximum coercivity and squareness were obtained for samples fabricated at treduc/oxid= 0.5 ms and toff =400 ms. the coerciv...
In the past year we focused on developing the metal nanostructure simulation, nanowire growth, and device fabrication. We explored a new geometry with Hertzianlike disc shaped antennas to replace the bowtie antennas we had initially investigated to achieve better performance. Light absorption enhancement of the nanodimers in terms of size and inter space was simulated. A testbed structure based...
