Abstract This paper presents the synthesis of two cluster compounds {(NH 4 ) 2 [Co(H O) 6 ] V 10 O 28 ·4H ( C1 and (NH [Ni(H C2 )} which were obtained as single crystals suitable for XRD analysis that revealed their crystallization in monoclinic (C2/c) triclinic (P-1) space groups, respectively. Additionally, characterized using CHN FT-IR spectroscopy thermal decomposition mechanisms investigat...

Understanding precipitation chemistry is highlighted as important worldwide due to its close relationship with air quality and impacts on ecosystems. However, the chemical composition of limited in Tibet, where alpine ecosystems are sensitive global change. Here, rainwater samples were collected Nyingchi city from January 2021 December 2021, a total 44 obtained. Major ions (NO3−, NH4+, Cl−, SO4...

By analyzing the mass concentrations and compositions of atmospheric PM2.5 in Shaoxing from December 2019 to February 2020, characteristics carbon-containing components, water-soluble ions metal elements were obtained. NO3−, OC, SO42− NH4+ main components winter. The OC/EC ratio was 3.27, which proved existence SOC. proportion SOC OC 47.3%, showed that secondary sources made a significant contr...

Nakhoul, Nazih L., Kathleen S. Hering-Smith, Solange M. Abdulnour-Nakhoul, and L. Lee Hamm. Transport of NH3/NH4 1 in oocytes expressing aquaporin-1. Am J Physiol Renal Physiol 281: F255–F263, 2001.—The aim of this study was to determine whether expressing aquaporin (AQP)-1 could affect transport of NH3. Using ion-selective microelectrodes, the experiments were conducted on frog oocytes (cells ...

In this study, the water-soluble inorganic ions (WSIIs) composition of fine particulate matter (PM2.5) was measured in northern Nanjing city from 2015 to 2021. NH4+, NO3− and SO42− concentrations dominated total WSIIs (Na+, K+, Mg2+, Ca2+, Cl−, SO42−), accounting for 87.8%. The nitrate with highest average concentration among all 11.0 μg·m−3. Total were higher winter lower summer, levels Decemb...
