Reply Part 1 We want to thank all three reviewers for their thoughtful and thorough reading of our manuscript and for their comments. We are replying to these comments below and have included the comments for convenience. Our replies are preceeded by ‘Reply:’. ∗∗∗ Anonymous Referee #1 ∗∗∗ p. 2132, l. 4-13: “If we understand correctly, all the calculations do not assume an initial presence of br...

This Letter reports reliable satellite data in the period of 1980-2007 covering two full 11-yr cosmic ray (CR) cycles, clearly showing the correlation between CRs and ozone depletion, especially the polar ozone loss (hole) over Antarctica. The results provide strong evidence of the physical mechanism that the CR-driven electron-induced reaction of halogenated molecules plays the dominant role i...

We present an Al2O3 dielectric layer on molybdenum disulfide (MoS2), deposited using atomic layer deposition (ALD) with ozone/trimethylaluminum (TMA) and water/TMA as precursors. The results of atomic force microscopy and low-energy ion scattering spectroscopy show that using TMA and ozone as precursors leads to the formation of uniform Al2O3 layers, in contrast to the incomplete coverage we ob...

Ozone is the triatomic state of oxygen, that is, it is a molecule comprising of three oxygen atoms having the chemical symbol O3. Although ozone does exist naturally, it is a relatively unstable and reactive gas. Therefore ozone exists in the lower atmosphere at low concentrations. The greatest quantities of natural ozone are found at levels of up to 6 ppm in the stratosphere, thus the term the...

The world has long been struggling with environmental issues. depletion of the ozone layer, greenhouse effect, and water pollution are just a few many problems earth is facing. Despite efforts to try improve environment, it seems that situation only getting worse. One most pressing issues currently facing deforestation. Nigeria among countries face this challenge making an effort arrest by intr...

Not much has been written about air cleaning from ozone. The aim of this paper was to demonstrate the possibility of adsorption air cleaning from ozone. The second aim was to investigate the dependence of the efficiency of ozone removal from the air on the height of the adsorber layer and on concentrations of ozone, and to obtain empirical formulas for calculating the efficiency of ozone treatm...
