Titanium dioxide thin films were deposited on (0001) -quartz substrate by spray pyrolysis method. The method which an aerosol of Titanium Butoxide, generated ultrasonically, was sprayed on the substrate at temperature of 400 ̊C, kept at this temperature for periods of 3, 13, 19 and 39 hours. The developed films at a crystal phase correspond to the TiO2 anatase and rutile phases. Their surface r...

In this study, titanium thin films were deposited on alumina substrates by radio frequency (RF) magnetron sputtering. The mechanical properties of the Ti coatings were evaluated in terms of adhesion strength at various RF powers, temperatures, and substrate bias voltages. The coating conditions of 400W of RF power, 250°C, and a 75V substrate bias voltage produced the strongest coating adhesion,...

The entrapping of physicochemical active molecules inside mesoporous networks is an appealing field of research due to the myriad of potential applications in optics, photocatalysis, chemical sensing, and medicine. One of the most important reasons for this success is the possibility of optimizing the properties that a free active species displays in solution but now trapped inside a solid subs...

Abstract Nano-acoustic strain generation in thin metallic films via ultrafast laser excitation is widely used material science, imaging and medical applications. Recently, it was shown that transition metals, such as titanium, exhibit enhanced photoacoustic transduction properties compared to noble silver. This work presents experimental results simulations demonstrate among metals tantalum exh...

Stable TiO2 sols were prepared using two nonaqueous sol–gel processes with titanium n-butoxide and titanium isopropoxide, respectively. Crystallization and phase transitions of powders and thin films were studied by ex situ and in situ X-ray diffraction. For both methods, TiO2 began to crystallize around 320 C in air. Using helium instead of air during heat treatment slowed down the crystalliza...

The finite element modeling (FEM) technique has been applied to study the loading-unloading characteristics, stress and strain fields of the bulk materials such as titanium, iron, copper and thin films of titanium and copper subjected to Berkovich nanoindentation process. The loading and unloading curves obtained from numerical simulation results are compared with the curves obtained earlier th...

We report the use of a newly developed micromachining technique to fabricate microfluidic networks in thin titanium foils. These devices are used to geometrically confine and align self-assembled protein systems for confocal microscopy and transmission x-ray scattering experiments. X-ray attenuation can be easily reduced or eliminated from the thin foil devices by backside etching or through-et...

Surface modification of titanium and its alloys is of great importance for their practical application as biomedical implants. We have studied and compared assembly of dodecylphosphoric acid on commercial polished and on nanostructured titanium disks. The latter were produced by chemical etching that created nanoscale pits of typical size of about 20 nm. Enhanced hydrophobicity and high molecul...
