Air Ion Variation at Poultry-farm, Coastal, Mountain, Rural and Urban Sites in India
Pollution index Aerosol Air ion Transpiration Meteorological Parameters
2016/3/25
The air ions are continuously generated and destroyed by various processes in the atmosphere. Near the surface, the nature
of ions is very complex and they show large variations in their physical pro...
Metal Corrosion of Al-Si-Cu Pattern Wafer Due to Chloride Ion Contaminants
Airborne molecular contaminants (AMCs) Chloride contamination Cleanroom micro-contamination HCl Pattern wafer Semiconductor device
2016/3/28
Chloride ions (Cl–) induce metal corrosion of integrated circuits and cause wafer scrap events in the clean room
environment. In this study, Al-Si-Cu pattern wafers were designed to monitor critical ...
Ground Water in Certain Sites in Egypt and Its Treatments Using a New Modified Ion Exchange Resin—Characterization of Water and Modified Ion Exchange
Ion Exchange Groundwater Heavy Metals Sorption
2013/3/12
The present work is a comprehensive of drinking water quality. Eleven groundwater samples were taken from various rural regions of Egypt, the groundwater samples were investigated for chemical, radiom...
Dependence of the Ion-Aerosol Equivalent Attachment Coefficient on the Ratio of Polar Conductivities in a Steady State
Aerosol Ion Attachment coefficient
2016/3/28
The article discusses certain theoretical problems of the diffusion charging of aerosol particles in a bipolar ion
environment. The ratio of polar conductivities, induced by cluster ions of either po...
Diurnal and Seasonal Air Ion Variability at Rural Station Ramanandnagar (17°2N, 74°E), India
Gerdien condenser Transpiration Vegetation Temperature inversion Radio-active aerosol
2016/3/29
High-energy radiations, such as alpha and beta particles or gamma radiation, ionize air molecules into pairs of positive
ions and free electrons. The diurnal and seasonal variations of these air ions...
