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 ...

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.

BCC‐Associated Amyloidosis with a Peculiar Pattern of Deposition

The Journal of Dermatology, 1992
AbstractAn 83‐year‐old Japanese woman with lepromatous leprosy had been treated in a leprosarium. More than 10 years ago, she developed a dome‐like brown tumor on the dorsum of the nose which showed the histology of basal cell carcinoma. The lesion was a well bordered, rounded tumor with tumor cell nests on its periphery extending toward the center as ...

Local Distribution of Particles Deposited on Patterned Surfaces

Solid State Phenomena, 2009
In many process steps of integrated circuits (IC’s) fabrication, silicon wafers are coming in contact with process liquids such as ultra pure water (UPW) and aqueous and non-aqueous chemical mixtures. During these process steps, liquid-borne particle contamination can deposit on the wafer surface.

Pattern formation in noise-reduced electrochemical deposition

Physical Review E, 1993
Noise-reduced electrodeposition is performed in an agarose gel medium containing ${\mathrm{CuSO}}_{4}$ solution. Instead of random fractal-like patterns usually seen in ${\mathrm{CuSO}}_{4}$ aqueous solution electrodeposition, the deposit shows a more ordered morphology. The dendritic pattern with an evident main stem can be seen.

Microfluidic ultramicroscale deposition and patterning of quantum dots

Nanotechnology, 2005
The ability to directly deposit materials in ultraminiaturized domains with nanoscale accuracy could play a central role in the realization of some forms of nanotechnology. In this report we demonstrate the direct deposition of quantum dots in patterns with ultramicroscale (1-15 microm) and nanoscale (

Patterns in Melting Snow and Vapor Deposited Layers

Physical Review Letters, 2004
We have observed a natural periodic pattern occurring in partially melted snow lying on the ground under certain atmospheric conditions. We explain this phenomenon quantitatively by considering heat flow through this layer coexisting in two phases (snow and water). Our model equations exhibit a range of patterns depending on the average density of snow.

Patterned Deposition of Allophane Nanoparticles on Silicon Substrates

Clays and Clay Minerals, 2012
AbstractIn order to obtain nanopatterned surfaces, natural allophane particles originating from Japanese soils were immobilized as single particles on Si wafer substrates.When derived from aqueous suspensions, only a few nanoparticles were deposited and detected on the surface due to the weak adsorption of allophanes on the substrate.
