Every living organism breathes in air. The wind is referred to as the moving air. Occupation of Space: Air is a blend of various gases. These also fill up areas like other matters. A balloon enlarges because the air is blown into it and covers the bare spaces. Pressure exerts by Air:...
The data of air pollution and gases were obtained from Voivodeship Inspectorate for Environmental Protection in non-industrial area (Bialystok) and industrial area (Katowice). In the analysis, we used the concentration of SO 2, NO2, CO, and particulate matter with a diameter of 2.5 μm or le...
Main Understanding and controlling the interactions between a single quantum degree of freedom and its environment represents a fundamental challenge within the quantum sciences1,2,3,4,5,6,7,8,9. Typically, one views this challenge through the lens of mitigating decoherence—enabling one to ...
BH-4M portable multi gas detector could detect combustible gas, O2 and other two types toxic gases continuously and simultaneously. It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as ...
We explored in-gap states (IGSs) in perovskite oxide heterojunction films. We report that IGSs in these films play a crucial role in determining the formation and properties of interfacial two-dimensional electron gas (2DEG). We report that electron trapping by IGSs opposes charge transfer from ...
Due to the existence of N2 and CO2 gases in the geothermal aquifers and oil wells (Minissale et al., 1997; Arnórsson et al., 2010; Stáhl et al., 2000; Malimo, 2013; Heřmanská, 2020; geoSCOUT database), we have selected mixtures of CO2-water and air (i.e., N2/O2)-water...
Natural convection heat transfer of a heated enclosure has widespread application in industries dealing with fluids. Its application includes solar collectors, thermal storage systems, building thermal design, aviation thermal management, heat dissipation from electronic devices, air conditioning, heaters, che...
