Degradation of acrylic water base color from synthetic wastewater by the Fenton process was performed. Experiments were conducted on the sample containing 100 and 400 mg/l of Acrylic water base color. The study was performed for searching optimum values of FeSO4 and H2O2 concentration, pH and temperature. The H2O2 requirement seems to be re...

This work calculates the Lorentz–Lorenz coefficient with refractive index and density values of various molecules in their solid phase measured our laboratory under astrophysical conditions. was completed for a range temperatures from 13 K to close sublimation temperature each molecule. The studied were N2, CO2, NH3, CH4, CH3OH, C2H4, C2H6. For results match those found unique similar previous ...

This paper investigates four of the constitutional isomers Si2H2+, namely butterfly, vinylidene-like, monobridged, and trans structures. These isomer geometries were all studied using CCSD(T) method with basis sets as large cc-pV5Z. Higher level methods CCSDT CCSDT(Q) used for final energetics. It is found that butterfly has lowest energy, followed by vinylidene-like monobridged structures; str...

Context: It has been proposed that H$_2$ near-infrared lines may be excited by cosmic rays and allow for a determination of the cosmic-ray ionization rate in dense gas. One-dimensional models show measuring both gas column density line intensity enables constraint on as well spectral slope low-energy protons interstellar medium (ISM). Aims: We aim to investigate impact certain assumptions regar...

Abstract. Carbon monoxide (CO), acetylene (C2H2), ethane (C2H6), formaldehyde (H2CO), and hydrogen cyanide (HCN) are important trace gases in the atmosphere. They highly related to biomass burning, fossil fuel combustion, biogenic emissions globally, affecting air quality climate change. However, variations correlations among these species not well known northern China due limited measurements....
