An overview of atmospheric deposition chemistry over the Alps: present status and long-term trends [PDF]

open access: yes, 2006
Several research programs monitoring atmospheric deposition have been launched in the Alpine countries in the last few decades. This paper uses data from previous and ongoing projects to: (i) investigate geographical variability in wet deposition ...

Modeling Effects of Atmospheric Nitrogen Deposition on the Water Quality of the MR-SNWDP

open access: yesAtmosphere, 2022
Modeling the effects of atmospheric deposition on the water quality of the middle route of the South-to-North Water Diversion Project (MR-SNWDP) can provide a basis for scientific protection and optimal allocation of water resources.

Dry Deposition of Atmospheric Nanoparticles

open access: yes, 2021
The increasing number of pollutants emitted or released during and after the industrial revolutions caused major changes that were harmful to the environment and the health of the population. The harms resulting from air pollution were evident in the most industrialized regions, due to the large amount of pollutants emitted in these regions ...

A simple model to estimate atmospheric concentrations of aerosol chemical species based on snow core chemistry at Summit, Greenland [PDF]

open access: yes, 1995
A simple model is presented to estimate atmospheric concentrations of chemical species that exist primarily as aerosols based on snow core/ice core chemistry at Summit, Greenland. The model considers the processes of snow, fog, and dry deposition.

Impact of mercury atmospheric deposition on soils and streams in a mountainous catchment (Vosges, France) polluted by chlor-alkali industrial activity: The important trapping role of the organic matter [PDF]

open access: yes, 2006
Total atmospheric Hg contamination in a French mountainous catchment upstream from a chlor-alkali industrial site was assessed using Hg concentrations in the deepest soil horizon, in the stream bottom sediments, in river waters and in bryophytes.

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

open access: yes, 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 ...

Nonequilibrium Atmospheric Plasma Deposition [PDF]

open access: yesJournal of Thermal Spray Technology, 2011
This study is a review of plasma enhanced chemical vapor deposition (PECVD) at atmospheric pressure. Sources for coatings over large area are presented. Millimetric torches and microplasmas are next studied for localized PECVD. A specific attention is paid to the way power is dissipated and the consequences it has on the deposition rate and on quality ...
