  Heavy Organics Deposition and Fouling in Petroleum Fluids
The kind and amount of depositions of heavy organics from petroleum fluids vary depending on the hydrocarbons present in oil and the relative amounts of each family of heavy organics.
Some of the heavy organics (specially asphaltenes) will separate from the oil phase into an aggregate (large particles) and then will remain suspended in oil by some peptizing agents, like resins, which will be adsorbed on their surface and keeping them afloat as demonstrated by Figure 3.
The factors influencing this effect are the electrical and thermal characteristics of the conduit, flow regime, flowing oil properties, characteristics of the polar heavy organics and colloidal particles, and blending of the oil.

 "Lockerbie Trial Document: Susan Lindauer Deposition" (4 December 1998)
While Dr. Fuisz is still unable to comment on this matter because of the gag order, MEIB has obtained a copy of a formal deposition filed by Lindauer in 1998 in which she recounts this conversation in detail.
This deposition (see below) has been submitted to the court in which two Libyan suspects are currently on trial and to U.N. officials, who have attempted to persuade the Clinton administration to lift the gag order on Dr. Fuisz.
She has agreed to publish her email address, slndau@aol.com, along with this deposition so that journalists, researchers and others interested in learning more about this issue can contact her.

 CATHOLIC ENCYCLOPEDIA: Deposition   (Site not responding. Last check: 2007-11-05)
A deposition is an ecclesiastical vindictive penalty by which a cleric is forever deprived of his office or benefice and of the right of exercising the functions of his orders.
Moreover, deposition always deprived ecclesiastics of the office they held by the ordinary title of ordination, and it was nearly always coupled with the ceremony of divesting delinquents of the garments used in the functions of their sacred ministry.
Deposition from office always effects the loss of the benefice annexed to it, as benefices are given on account of the spiritual office.

 Modeling Atmospheric Deposition from a Cesium Release in Spain Using a Stochastic Transport Model
Deposition is the transfer of airborne material (gaseous and particulate) to the earth's surface, and may be classified as `dry' or `wet', depending on whether or not precipitation is involved.
Dry deposition occurs near the earth's surface, while wet deposition involves absorption of airborne pollutants onto precipitable elements (water droplets, ice particles, graupel, etc.) and is another means by which pollutants reach the earth's surface.
Gaseous deposition is typically a function of chemical activity, solubility, and diffusion characteristics, while particulate deposition depends on particulate shape, size distribution, density, impaction, solubility, gravitational settling, and diffusion (Sehmel 1980).

 Sputter deposition for semiconductor manufacturing
Sputter deposition is usually carried out in diode plasma systems known as magnetrons, in which the cathode is sputtered by ion bombardment and emits the atoms, which are then deposited on the wafer in the form of a thin film.
While the deposition is mostly forward, there is a small component which can deposit back onto the cathode surface because of in-flight gas scattering, reflection of the depositing atoms at other surfaces, less-than-unity sticking of the depositing atoms, or even resputtering from other surfaces in the chamber [4].
Sputter deposition is likely to continue to be used for semiconductor applications because of the large, already installed base of PVD systems, the simplicity of the process, and the wealth of associated understanding.

 Acid Deposition   (Site not responding. Last check: 2007-11-05)
While this form of wet deposition (often referred to as acid rain) is more widely understood and monitored, dry deposition from the atmosphere also occurs and is the result of complex atmospheric processes such as “settling”, “impaction”, and “absorption”.
Wet deposition is the major removal process for most particles and may be a factor in the elimination of gaseous contaminants as well.

 Deposition Processes
When an electrical potential is applied between a conducting area on the substrate and a counter electrode (usually platinum) in the liquid, a chemical redox process takes place resulting in the formation of a layer of material on the substrate and usually some gas generation at the counter electrode.
The deposition is best controlled when used with an external electrical potential, however, it requires electrical contact to the substrate when immersed in the liquid bath.
PVD covers a number of deposition technologies in which material is released from a source and transferred to the substrate.

 Deposition (chemistry) Summary
Deposition processes are the most important way contaminants such as acidic sulfur compounds are removed from the atmosphere; they are also important because deposition processes transfer contaminants to aquatic and terrestrial ecosystems.
In chemistry, deposition is the settling of particles (atoms or molecules) or sediment from a solution or suspension mixture, or the production of a solid on a pre-existing surface.
Deposition of particles is an aggradational process — one that builds a landform — as opposed to a degradational process that erodes or reduces the size of a landform.
