Nitrous oxide (N2O) is hazardous gas extensively used in surgeries as an anesthetic and released into the atmosphere without any treatment. Despite low concentrations atmosphere, it has for 300 times larger warming coefficient to greenhouse effect than CO2. There are only a few studies dedicated development of N2O sensors, but not room temperature (RT) ultra-low concentrations. In this study, we developed ultrasensitive gas-sensing device operating at RT based on CuO/TiO2 heterojunctioned...
Cobalt-doped ZnO (CZO) thin films were deposited on glass substrates at room temperature by radio frequency (RF) magnetron sputtering of a single target prepared with and Co3O4 powders. Changes in the crystallinity, morphology, optical properties, chemical composition CZO investigated various powers 45, 60, 75 W. All samples presented hexagonal wurtzite-type structure preferential c-axis (002) plane, along distinct change strain values through X-ray diffraction patterns. Scanning electron...
In this article, the process of creating calcium phosphate coatings through plasma electrolytic oxidation was investigated. Calcium were deposited onto titanium substrates fabricated via selective laser melting (SLM) method. The correlation between characteristics coating and applied voltage (200, 250, 300 V) PEO studied. surface morphology analysis indicates that an increase in results a larger pore size. It discovered that, when V applied, layer hydroxyapatite formed. However, at V,...
The hydrogen (H2) energy industry has continued to expand in recent years due the decarbonization of global system and drive towards sustainable development. Due hydrogen's high flammability significant safety risks, efficient detection become an increasingly hot issue today. In this work, a new type relatively fast responsive conducting polymer sensor been demonstrated for tracing H2 gas nitrogen environment. Inspiration unique properties carbon nanotube (CNT) graphene, polyaniline (PANI)...
Abstract Binary systems (layers) and multicomponent layers with bilayer thicknesses varying from microns to a few nanometers are considered. A strong dependence of the microstructure formation on deposition conditions (the magnitude bias potential, flow inert reactive gases, ion beam power (current density) supplied target) is found. General regularities in change functional properties structural state coatings formulated. The for columnar structure growth texture noted; various mechanisms...
Abstract The influence of silver ions on the antibacterial properties and morphology hydroxyapatite-silver (HA-Ag) hydroxyapatite-alginate-silver (HA-Alg-Ag) nanocomposites was studied. microstructure phase composition obtained were investigated by scanning electron microscopy, transmission x-ray diffraction Fourier transform infrared spectroscopy, formation crystalline Ag 3 PO 4 proved. According to results, incorporated into HA structure, partially replacing calcium ions. Assessment...
The results of studies the physical and mechanical properties nitride carbide multilayer systems based on ((TiZrNbTa)N, depending methods deposition heat treatment are analyzed summarized. coatings were deposited by magnetron sputtering. Studies original processed alloy samples carried out in a regional engineering laboratory. When extremely high doses N + ions (10 18 cm -2 ) introduced into nanostructured (TiZrNbTa)N, structure is formed, consisting amorphous, nanocrystalline (dispersed)...
Hydrogen (H 2 ) is considered a next-generation energy source with diverse applications across valuable social, economic, and industrial sectors, including transportation, biomedical, power generation, space exploration. Due to its low ignition wide flammable range, there an urgent global demand for ultrasensitive, lightweight, portable, wearable, flexible hydrogen sensors identify early gas leaks prevent environmental economic implications. In this study, we present sensor based on...
Metal oxide semiconductors (MOS) based gas sensors have been identified as a promising solution for future applications due to their exceptional electrochemical, physical, and sensing properties. Due excellent optical electrical features, ZnO nanostructures become increasingly popular detection applications, mainly because of abundant availability. Despite its potential, the ZnO-based challenges such poor selectivity high power consumption at elevated operating temperatures. Transition metal...
