In order to identify the pollution characteristics and sources of PM2.5 in Urumqi, fine particulate matter samples were collected from September 2017 August 2018, water-soluble ions (WSIs), organic carbon (OC), elemental (EC), polycyclic aromatic hydrocarbons (PAHs), metal elements analyzed. The results indicate that annual mass concentration Urumqi was 158.85 ± 15.11 ?g/m3, with highest season...

Background: Reverse Osmosis (RO) is an increasingly common method of desalination. A full scale water desalination system by membrane technology (RO) evaluated in a southern city (Jask) in Iran. Methods: First, data collection on water supply and network were performed. Analysis on most of the water quality parameters (Turbidity, pH, EC, Cl-, Na+, Alkalinity, Ca, Na, K, No3, No2, Fe, Mg, Mn, NH...

Zinc Anodes In article number 2202419, Pinhua Rao, Won Mook Choi, Jianfeng Mao, and co-workers report that a trace organic gamma butyrolactone (GBL) additive can improve the reversibility stability of Zn anode. GBL molecules rearrange ‘Zn2+-H2O-SO42−-GBL’ bonding-network aqueous electrolyte absorb on surface, reducing water activity, suppressing corrosion formation by-product, enabling uniform ...

The ionic chemistry of various hydrogen mixtures (H2/N2, H2/O2, and H2/air) has been studied in low pressure hollow cathode discharges. The major ions identified in the different discharges (H3, N2H, H3O and NH4) have been also found in astronomical observations or predicted in astrochemical models. The relative stability of the protonated ions in the various mixtures has been investigated in d...

Abstract. To study sea-derived gaseous amines, ammonia, and primary particulate aminium ions in the marine atmosphere of China's marginal seas, an onboard URG-9000D Ambient Ion Monitor-Ion Chromatograph (AIM-IC, Thermo Fisher) was set up on front deck R/V Dongfanghong-3 to semi-continuously measure spatiotemporal variations concentrations atmospheric trimethylamine (TMAgas), dimethylamine (DMAg...

LaMnO3 with perovskite structure is a SCR de-NOx catalyst good performance at low temperatures. In this paper, the reaction process on 010 surface of was studied by DFT method, to guide development catalysts and their effective application. The results obtained through research indicate that both E-R L-H mechanisms exist surface. NH3 molecule can be absorbed L acid then oxidized lattice oxygen ...
