Regional Patterns of Wet Mercury Deposition

Environmental Science & Technology, 1994
Most of the mercury contamination in lakes and streams of nonindustrialized regions of the United States and Canada is derived from atmospheric deposition. In order to determine the regional patterns of these inputs, seven mercury-in-precipitation monitoring sites were established in Minnesota, North Dakota, and Michigan. A 3-year study showed that the

Instability Deposit Patterns in an Evaporating Droplet

The Journal of Physical Chemistry B, 2014
The characteristics of several patterns left after the evaporation of a particle-laden liquid droplet are investigated by using a coarse-grained lattice model. The model includes both evaporative convection and the Brownian motion of weakly interacting particles.

Deposition Patterns of Nebulized Drugs: Is the Pattern Important?

Journal of Aerosol Medicine, 1994
It is logical to assume that the efficacy of an aerosolized drug should be related to the local airway dose. To test this assumption, it is necessary to have some index of the distribution of deposited drug within the airway and a measure of efficacy.

Pattern of lean and fat deposition in adults

Nature, 1977
THE fact that obesity becomes more common when societies change from a subsistence/labour intensive to an affluent/sedentary way of life might be taken simply as a demonstration that easy living encourages slothfulness and gluttony. Fat people, however, do not in general seem to eat more than thin ones, and there is increasing evidence of an inherited ...

Effect of infill pattern and infill density at varying part orientation on tensile properties of fused deposition modeling-printed poly-lactic acid part

Proceedings of the Institution of mechanical engineers. Part C, journal of mechanical engineering science, 2019
Fused deposition modeling is an additive manufacturing process in which successive layers of material are deposited to create a three-dimensional object.

Laser deposition and patterning of diamond

Conference on Lasers and Electro-Optics Europe, 1994
Laser beams are finding a lot of applications in diamond technology because of the possibility of versatile control and easy optimization of their parameters.

Depositing copper patterns on Teflon

JOM, 1992
Printed circuit boards composed of patterned cooper features on poly(tetrafluorethylene), better known by the E.I. du Pont de Nemours and Company trade name Teflon, are currently used for high-frequency applications. The choice of these materials is based on the high conductivity of copper and the facts that Teflon has One of the lowest reported ...

PATTERN FORMATION IN ELECTROLESS DEPOSITION

Fractals, 1995
Metal-forest patterns of electroless deposits of silver and gold in thin-layer aqueous solutions were studied in connection with their chemical reactions. While the silver metal-forest with a simple redox reaction of Cu and Ag+ showed a DLA (diffusion limited aggregation)-like pattern, the gold metal-forest with a redox reaction of Pb and [Formula ...

Direct laser patterned deposition

Journal of Materials Science Letters, 1992
The ability to write a material pattern directly on a substrate without involving lithography is of considerable technological importance. Research efforts have been targeted towards the development of metal microstrips [1-13] and more recently of microconnections made of high-temperature superconductors [14-16].

Deposition of Patterned Glycosaminoglycans on Silanized Glass Surfaces

Langmuir, 2006
We report the robust attachment of glycosaminoglycans (GAGs) on silanized glass surfaces. Depositions were performed both by immersion and by application of a pattern by means of microcontact printing. Immunofluorescence assays were performed to verify the deposition and the quality of the patterns.
