In this work are discussed the technology for preparing and characterisation of indium-tin oxide (ITO) and ITO with titanium oxide underlayer thin films with properties appropriate for usage at elevated temperatures as heat reflective coatings and gas sensors. For preparing the samples the methods of radio frequency (RF) and DC-magnetron reactive sputtering were used. Sputtering of indium-tin and...
The paper presents the obtaining of transparent conducting ZnO thin layers and their application as interdigitated transparent Schottky electrodes in a silicon based metal-semiconductor-metal (MSM-PD) photodiode structure. Optically transparent electrodes from impurity-doped ZnO thin layers have been prepared by vacuum thermal deposition method from metallic powders of Zn, Al and Sn followed by oxidation...
Total hemoglobin (tHb), carboxyhemoglobin (COHb), and methemoglobin (MetHb) are usually measured with a CO-oximeter. Noninvasive and continuous measurement of these blood components is expected to decrease the pain of a patient. Therefore, we developed an instrument to measure oxygen saturation (SpO2), tHb, COHb, and MetHb non invasively. Multiwavelength LED (600, 625, 660, 760, 800, 940, and 1300...

A simple, robust and sensitive sequential injection spectrophotometric method for the assay of penicillamine (PA) in pharmaceutical formulations is developed. The method was based on the complex formation when PA is reacted with iron(III) solution in hydrochloric acid media. The deep blue colored PA-iron(III) complex produced is monitored at a maximum wavelength of 600 nm. A five level orthogonal...
