In this work, a planar solid-state potentiometric CO2 sensor for medical applications of the type CO2, O2, Au, Li2CO3-BaCO3 | Nasicon | Na2Ti6O13-TiO2, Au, O2, CO2 was developed in thick-film technology. Due to an integrated screen-printed platinum heater on the rear side, the sensor can be applied without changing its working temperature of 525°C in the main flow of the respiratory air of an i...

Phenol is a recalcitrant anthropogenic compound whose presence has been reported in both wastewater and drinking water; human exposure to phenolic substances can lead health problems. The degradation of phenol (measured as COD decrease) through solar heterogeneous photocatalysis with immobilized TiO2 was performed two different reactors: flat-plate reactor (FPR) parabolic collector (CPC). A 23 ...

Formaldehyde (FA) is an extremely active compound that widely used in numerous applications. Given FA a known carcinogen, it essential to remove from the environment. Titanium dioxide (TiO2), due its special physicochemical properties, promising adsorbent for removal of specific organic compounds aqueous solutions. In this study, interaction TiO2 with presence and absence quartz sand, most comm...

Phase velocity and attenuation of guided waves have been estimated from multireceiver, full waveform, acoustic logging data using the extended Prony's method. Since a formation affects velocity and attenuation, estimating these quantities is important in evaluating the formation properties. The estimation is performed using an array processing technique which requires two steps: (1) the traces ...

Multifunctional nanocomposites Ag/Al2O3/TiO2@β-cyclodextrin-graphene oxide (AATG) incorporating graphene sheets, TiO2, and Ag/Al2O3 nanoparticles were prepared in two steps. We benefited from the inherent properties of β-cyclodextrin to create a stable aqueous solution capable self-assembling situ grown TiO2 on nanosheets. catalysts with high surface-to-volume ratio by combustion technique urea...

Multi-functionalized and co-doped TiO2/C nanocomposites were derived from the pyrolysis of Ti-MOFs at 800 °C under different gaseous atmospheres their photocatalytic performance investigated. The atmosphere during plays a critical role in determining structural, textural, optical physicochemical properties composites due to synergistic effect nitrogen-containing species, carboxylate sulfur func...

Ofloxacin is a highly efficient and widely used antibiotic drug. It classified as refractory pollutant due to its poor biodegradability. Consequently, it commonly found in water sources, requiring methods for removal. Advanced oxidation processes (AOPs) offer alternatives since those yield complete degradation not achieved adsorption or membrane processes. Previous studies suggest ofloxacin fol...

The aim of this study was to investigate the photoactivity dioxide titanium (TiO2) nanotube films depending on different structure factors including pore size, tube length, wall thickness and crystallinity. Aqueous p-nitroaniline used as a probe assess photocatalytic activity layers under UV irradiations. Self-organized thin were prepared by electrochemical anodization (Ti) foils Ti sputtered o...

Dispersed and immobilized photocatalytic titanium dioxide (TiO2) nanoparticles were investigated for the removal of microcystin-LR (MC-LR) cyanotoxin in water. TiO2 concentrations (0.25 g/L, 0.025 0.0025 0 g/L) compared to coated on nylon net supports uncoated nets determine MC-LR degradation performance. Adsorption onto dispersed was tested 1 h prior ultraviolet (UV) light exposure, maximum ad...
