31Negative index metamaterials — A negative index metamaterial causes light to refract, or bend, differently than in more common positive refractive index materials. Negative index metamaterials or negative index materials (NIM) are artificial structures where the refractive… …
32Materiality (Interior Design) — Materiality in interior design is the concept of the physical consolidation of matter that informs us about our surroundings. Ultimately materials within an interior environment influence how one experiences that particular space whether they are …
33Optical fiber — A bundle of optical fibers A TOSLINK fiber optic audio c …
34Deformation (engineering) — This article is about deformation in engineering. For a more rigorous treatment, see Deformation (mechanics). Compressive stress results in deformation which shortens the object but also expands it outwards. In materials science, deformation is a …
35Copper alloys in aquaculture — A copper alloy pen that has been deployed on a fish farm at depth of 14 feet for one year shows no signs of biofouling. Recently, copper alloys have become important netting materials in aquaculture (the farming of aquatic organisms including… …
36Sonoma State University — seal Motto Lux Mentis, Lux Orbis (Latin Motto in English Light of the Mind, Light of the World Established …
37Ultra high vacuum — (UHV) is the vacuum regime characterised by pressures lower than about 10−7 pascal or 100 nanopascals ( 10−9 torr). UHV requires the use of special materials in creating the vacuum system, extreme cleanliness to maintain the vacuum system, and… …
38Intelligence analysis management — This article deals with the roles of processing/analysis in the real world intelligence cycle as a part of intelligence cycle management. See Intelligence analysis for a discussion of the techniques of analysis. For a hierarchical list of… …
39Bow (weapon) — A bow is a weapon that projects arrows powered by the elasticity of the bow. As the bow is drawn, energy is stored in the limbs of the bow and transformed into rapid motion when the string is released, with the string transferring this force to… …
40Sulfur-iodine cycle — The sulfur iodine cycle (S I cycle) is a series of thermochemical processes used to produce hydrogen.The S I cycle consists of three chemical reactions whose net reactant is water and whose net products are hydrogen and oxygen. All other… …
