Polyimide (PI) films by chemical vapor deposition (CVD): Novel design, experiments and characterization [PDF]

, 2007
Polyimide (PI) has been deposited by chemical vapor deposition (CVD) under vacuum over the past 20 years. In the early nineties, studies, experiences and characterization were mostly studied as depositions from the co-evaporation of the dianhydride and ...

History of nutrient inputs to the northeastern United States, 1930–2000 [PDF]

, 2013
Humans have dramatically altered nutrient cycles at local to global scales. We examined changes in anthropogenic nutrient inputs to the northeastern United States (NE) from 1930 to 2000.

Global deposition of total reactive nitrogen oxides from 1996 to 2014 constrained with satellite observations of NO2 columns [PDF]

, 2017
Reactive nitrogen oxides (NOy) are a major constituent of the nitrogen deposited from the atmosphere, but observational constraints on their deposition are limited by poor or nonexistent measurement coverage in many parts of the world.

New Insights Into Multi‐Component Atmospheric Wet Deposition Across China: A Multidimensional Analysis

Earth's Future, 2022
Atmospheric wet deposition has attracted much attention because of its removal function of aerosol particles and impact on ecosystem. It is a complex multi‐component process due to various pollutants emission sources and reaction processes.

Comparison of mercury in atmospheric deposition and in Illinois and USA soils [PDF]

Hydrology and Earth System Sciences, 2004
It has been reported that most mercury (Hg) in USA soils is from atmospheric Hg deposition, mostly from anthropogenic sources. This paper compares the rates of atmospheric Hg deposition to amounts of Hg in Illinois and USA soils. The amounts of Hg in
