	Selective surface - Wikipedia, the free encyclopedia
		In solar thermal collectors, a selective surface is chosen based on the ratio of radiation-absorption (alpha) to radiation-emission (epsilon), with a higher ratio meaning better performance.
		One of the first selective surfaces investigated was simply copper with a layer of fl cupric oxide.
		Black chromium ("fl chrome") nickel-plated copper is another selective surface that is very durable, highly resistant to humidity or oxidizing atmospheres and extreme temperatures while being able to retain its selective properties - but expensive.

	Selective surface, endosseous dental implants - United States Patent 5,885,079
		Externally-threaded implants usually have an unthreaded portion at the proximal end of the implant that is commonly referred to as the neck portion, with the remainder of the external surface substantially threaded to or near to the distal end of the implant.
		Regardless of the smoothness of the HA surface, it is unsuitable material for coating the neck portion of an implant that may become exposed to oral mucosa when crestal bone recession occurs around the top of the implant.
		The neck surface may be machined, as in the Branemark/Nobel-pharma dental implant, or machined and acid etched to remove loose titanium particles from the surface, as in Core-Vent Corporation's Screw-Vent implant, or the neck may be polished or made of a ceramic.

	Method for improved surface planarity in selective epitaxial silicon - Patent 4786615
		said layers being selectively grown in an aperture of a mask, while substantially avoiding deposition on the mask; and terminating the growth of selective epitaxial silicon when the selective eptaxial silicon is substantially planar with the mask.
		When selective epitaxial silicon is to be used for the IC device fabrication, its thickness needs to be controlled to the same height as that of the mask.
		For example, while the selective epitaxial silicon was grown by chemical vapor deposition at two temperatures in two steps, it will be apparent to those skilled in the art that further steps could be used alternating the growth of the epitaxial silicon at the two temperatures.

		The surface may be roughened, corrugated, coarse, lined or knurled in a regular or irregular, predetermined or random fashion and may possess numerous very small knobs, projections, ridges, points, or protuberances to give it the desired flat, dead or dull mat appearance.
		Further, the surface of the wear layer is raised to the more highly elevated temperature whereby those areas thereof, which do not possess the higher melt viscosities or the polymerized or cross-linked monomers, soften, melt and flow to form the sleek, glossy and lustrous surfaces.
		The strippable coarsely textured release surface upon which the resinous wear layer was originally cast or formed is then removed and reveals a suitable textured or embossed surface on the resinous wear layer, precisely corresponding to the textured or embossed surface of the release material.

	Surface Hardening of Steels
		Surface hardening a process which includes a wide variety of techniques is used to improve the wear resistance of parts without affecting the softer, tough interior of the part.
		This combination of hard surface and resistance and breakage upon impact is useful in parts such as a cam or ring gear that must have a very hard surface to resist wear, along with a tough interior to resist the impact that occurs during operation.
		Selective hardening generally involves transformation hardening (from heating and quenching), but some selective hardening methods (selective nitriding, ion implantation and ion beam mixing) are based solely on compositional modification.

		Selective surfaces, incorporating DC reactively sputtered stainless steel-carbon (SS-C), were intensively studied in this school during 1970s to 1980s.
		Recently we have made two very significant innovations related to solar selective coatings, double cermet layer structure for achieving the highest solar performance and metal-aluminium nitride (M-AlN) solar selective coatings deposited by a novel two-target DC magnetron sputtering technology for reducing the costs of high-temperature solar coatings.
		Through fundamental analysis and computer modelling, we have developed a double cermet film structure for solar selective surfaces and achieved theoretically and experimentally better solar performance than surfaces using a homogeneous cermet layer or the conventional graded film structure.

		Most of this radiation has short wavelength as it comes from the sun's surface with a temperature of some 5800 K. To the extent that the hot fl road is a "fl body", it absorbs all the sun's incident radiation.
		Selective Surfaces: It would be great fun to find a way to create a surface that could get hotter than a hot fl road in the sun, maybe even one that could boil water.
		To create our selective surface, we start with a layer of stainless steel and add a thin layer of gold and, on top of that, a thin layer of silicon.

	54. : Mechanics of the Selective Laser Raster-Scanning Surface Interaction
		This permits distribution of laser energy precisely over geometric patterns such as rectangles, circles, triangles etc. The surface thermal history at any given point under such processing was estimated using an analytical solution for the 1D, semi-infinite, surface flux boundary condition heat conduction problem together with linear superposition theory.
		Presented here is the comparison of the thermal histories of different selective laser surface processes previously implemented, namely:laser surface polishing of flat surfaces, laser induced cementation of cylindrical surfaces and direct laser single layer masked deposition.
		Understanding the influence of scan geometry and overlapping on the selective raster-scan processing provides a method to tailor the surface peak temperature as well as the heating and cooling rates, affecting the solidification or sintering conditions and therefore the mechanical properties of the parts obtained.

		“The asset of surface ablation is that it removes tissue less deeply in the cornea and appears to have less of a tendency to induce ectasia,” Dr. Lindstrom said.
		He also favors surface ablation for patients that have epithelial basement membrane dystrophy, where they are more likely to have an epithelial defect as a result of a LASIK procedure, as well as for those with topographic anomalies.
		While surface ablation has gained popularity, it still has its weaknesses, not the least of which is the discomfort that can accompany the procedure.

		We subsequently found that c-mpl is expressed at the cell surface by a subset of murine and human HSC/PC that are enriched for cells capable of long-term multilineage hematopoietic repopulation in primary recipients [20].
		These studies further indicate that c-mpl is a selective human HSC surface receptor with a relevant role in the regulation of the stem cell compartment, and have practical implications for HSC positive selection, expansion, and transplantation protocols for both basic research and clinical applications.
		Studies have suggested the existence of HSC from select tissue sources in early fetal life that are intrinsically different [38-40] and more primitive than HSC isolated from various tissue sources in later development and adult life [41].
