In recent years much work has been conducted in order to create patterned and structured polymer coatings using vapor deposition techniques - not only via post-deposition treatment, but also directly during the deposition process. Two-dimensional and three-dimensional structures can be achieved via various vapor deposition strategies, for instance, using masks, exploiting surface properties tha...

In this work, electrophoretic deposition (EPD) is reported to form gallium thin film with high deposition rate and low cost while avoiding the highly toxic chemicals typically used in electroplating. A maximum deposition rate of ~0.6 μm/min, almost one order of magnitude higher than the typical value reported for electroplating, is obtained when employing a set of proper deposition parameters. ...

Hydroxyapatite deposition disease (HADD), a disease most commonly found in middleaged individuals, is characterized by deposition of calcium phosphate crystals in periarticular tissues. The deposits frequently occur in tendons near their osseous attachments, most commonly involving the supraspinatus tendon. The etiology of HADD is unclear, but may be related to repetitive trauma or metabolic di...

A lung deposition model for fibrous aerosol needs accurate deposition equations for different regions of the human respiratory tract. For fiber deposition in the tracheobronchial region there are several theoretical and empirical equations to predict deposition efficiency in the impaction-dominant region. However, few were verified with experimental data. We have obtained experimental data of f...

MODIFICATION OF DEPOSITION PROCESS PARAMETERS FOR UNIFORM INDIUM LAYER DEPOSITION Isaac Butt Old Dominion University, 2017 Director: Dr. Sylvain X. Marsillac The need for more efficient light to energy converting cells has long been a subject of research and development. With abundant availability of solar energy that the earth receives, the photovoltaic industry has sought materials that could...

Mercury (Hg) in autumn litterfall from predominately deciduous forests was measured in 3 years of samples from 23 Mercury Deposition Network sites in 15 states across the eastern USA. Annual litterfall Hg dry deposition was significantly higher (median 12.3 micrograms per square meter (μg/m(2)), range 3.5-23.4 μg/m(2)) than annual Hg wet deposition (median 9.6 μg/m(2), range 4.4-19.7 μg/m(2)). ...

Atmospheric deposition has long been recognized as an important source of pollutants and nutrients to ecosystems. The need for reliable, spatially explicit estimates of total atmospheric deposition (wet + dry + cloud) is central, not only to air pollution effects researchers, but also for calculation of input-output budgets, and to decision makers faced with the challenge of assessing the effic...

Ozone/TEOS thermal chemical vapor deposition ~CVD! has been investigated for SiO2 deposition on Si, using a cold-wall research reactor equipped to determine the effects of precursor concentration, deposition temperature ~300–500 °C!, and pressure ~30–200 Torr! on deposition rates, etch rates, and step coverage in the regime of subatmospheric CVD ~SACVD!. Deposition rates first increase with sub...
