In this paper, mathematical modeling and simulation of a MEMS-based clamped square-shape membrane for capacitive pressure sensors have been performed. Three types of membrane materials were investigated (i.e. Zinc Oxide (ZnO), Zinc Sulfide (ZnS) and Aluminum Nitride (AlN)). Various performance parameters such as capacitance changes, deflection, non...

An investigation of room-temperature sol–gel synthesis Ag doped ZnO nano-particles are reported here. The effect of silver concentration (2, 4, 6, 8 and 10 at. wt.%) on the morphology, structural and optical properties of the Ag doped ZnO nanoparticles are studied. XRD analysis displays the hexagonal wurtzite structure. The crystallite size was fou...

As an alternative approach to the conventional deposition and photolithographic processes, the laser digital patterning (LDP) process, which is also known as the laser direct writing process, has attracted considerable attention because it is a non-photolithographic, non-vacuum, on-demand, and cost-effective electrode fabrication route that can be ...

Namen magistrske naloge je preveriti, kakšen vpliv ima biomolekularna korona izbranih nanomaterialov na vzajemno delovanje med nanomateriali in celicami. Testirali smo vpliv nanodelcev (ND) s predhodno ustvarjeno korono iz govejega serumskega albumina - BSA (predhodno oblečeni ND) ter tistih brez predhodno ustvarjene korone (predhodno neoblečeni ND...

Gas response control through structural and defect engineering in metal oxides are critical approaches to realize high performance sensors. Herein, we present the fabrication of ZnO thin films containing nanosized structures and high concentration of zinc interstitials for NO2 and ethanol monitoring. The target materials were fabricated by aerosol ...

A modified facile method is presented to synthesise quantum-sized zinc oxide nanoparticles within the pores of a mesoporous silica host (SBA-11). This method eliminates the 3 h alcohol reflux and the basic solution reaction steps of zinc acetate. The mesoporous structure and the ZnO nanoparticles were analysed by X-ray diffractometry, transmission ...

The presented article concerns the comparison between two different zinc-oxide structures - bulk crystals and polycrystalline thin films. Bulk crystals were grown by a Bridgman method. For thin-film production, a sol-gel spin-coated method was chosen. A part of thin layers samples was annealed in 600 o\documentclass[12pt]{minimal} \usepackage{amsma...

Pristine ZnO, Cu2+:ZnO, Ce3+:ZnO and Cu2+, Ce3+:ZnO nanopowders with different doping concentrations (0, 0.31, 0.62, 0.93 and 1.24% of dopant) were synthesized by sol–gel technique with low sintering temperature of 600 °C. The powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy...

In the present work, Sr-doped ZnO (SZO) thin films were grown on heated glass substrates (250 °C) by the ultrasonic spray technique. The effect of strontium concentration on the structural and physical characteristics was studied. The molar ratio of strontium in the ultrasonically sprayed solution was varied from 0 to 5 at.%. Several characterizati...
