Intermediate alloy formed between foreign substrates and semiconductor material enable the growth of single crystal semiconductor films on the alloy layer. The melted film must not ball up on the surface of the substrate and neither chemically react nor alloy with the intermediate alloy formed on the substrate.
Coating-to-substrate bonding between plasma sprayed tungsten and preheated tungsten substrates
Bi and Ag nucleation on evaporated substrates studied as function of substrate temperature and impinging flux using electron microscopy
High-emittance coatings of iron, calcium, and zirconium titanates thermally sprayed on stainless steel, columbium-1 percent zirconium, and beryllium substrates promote and control radiative heat transfer from the metal substrates. Adherence, compatibility and emittance stability at elevated temperature and high vacuum were evaluated.
Normal spectral emittance of aluminum and zinc oxide applied to opaque substrates of different radiative properties
Thin film plastic substrate cadmium sulfide solar cell design and fabrication
Thin film cadmium sulfide solar cell array on plastic substrate development
Microbial synthesis of animal feeds from human waste substrates
Metallurgical bonding between plasma sprayed tungsten & hot tungsten substrates - interface & recrystallization
Droplet sedimentation in continuous flowing system to control enzyme-substrate reaction by diffusion and gravity
Backwall, thin film, cadmium sulfide solar cell on plastic film substrate
Porous-glass substrate is used for absorption of a dye used in measuring the concentration of atmospheric ozone at high altitudes. This measurement is based on the chemiluminescence produced in the reaction between ozone and the dye, rhodamine B. The porous glass provides a large interstitial surface area which promotes this reaction.

Fluorscein and naphthol substrates for phosphatase activity in soils detected by fluorometric assays - enzyme activity in soils by fluorescent emission
Hydrazine and derivations affecting carbon dioxide respiratory pattern of various metabolic substrates in rats
Device is developed to control the force used in manually placing chips on substrates. It controls the compression load between 2 small members at loads as low as 25 grams by means of a force control gage that is preset by varying the spring deflection.
Dependence on surface structure for adsorption energy by single atom on body centered cubic substrate
Electrically conductive layer of zirconium on a zirconium-oxide film residing on a zirconium substrate is formed by reducing the oxide in a sodium-calcium solution. The reduced metal remains on the oxide surface as an adherent layer and seems to form a barrier that inhibits further reaction.
