- It was subsequently shown by De Deene " et al " in 2002 that other antioxidants could be used in the manufacture of normoxic gels including tetrakis ( hydroxymethyl ) phosphonium chloride, having first been suggested to Baldock by Billingham in 1996.
- Compared to the simpler pattern for triangular stamps in which all diagonal perforations are parallel to each other, the tetrakis pattern has the advantage that, when folded along any of its perforations, the other perforations line up with each other, making repeated folding possible.
- Palladium ( II ) acetate, tetrakis ( triphenylphosphine ) palladium ( 0 ) ( Pd ( PPh 3 ) 4, and tris ( dibenzylideneacetone ) dipalladium ( 0 ) ( Pd 2 ( dba ) 3 ) serve either as catalysts or as starting materials for catalysts.
- The tetrakis square tiling is an infinite arrangement of lines forming a periodic tiling that resembles a multigrid with four parallel families, but in which two of the families are more widely spaced than the other two, and in which the arrangement is simplicial rather than simple.
- A fourth isohedral deltahedron with the same face planes, also a stellation of the compound of three octahedra, has the same combinatorial structure as the tetrakis hexahedron but with the cube faces dented inwards into intersecting pyramids rather than attaching the pyramids to the exterior of the cube.
- "' Tetrakis ( triphenylphosphine ) palladium ( 0 ) "'( sometimes called quatrotriphenylphosphine ) is the chemical compound Pd [ P ( C 6 H 5 ) 3 ] 4, often abbreviated PPh 3 ) 4, or even PdP 4, as well as.
- A different form of the tetrakis hexahedron, formed by using taller pyramids on each face of the cube, is non-convex but has equilateral triangle faces that again lie on the same planes as the faces of the three octahedra; it is another of the known isohedral deltahedra.
- The halide ( Br, Cl ) or triflate is an aryl, benzyl, or vinyl compound and the alkene contains at least one hydrogen and is often electron-deficient such as acrylate ester or an acrylonitrile . The catalyst can be tetrakis ( triphenylphosphine ) palladium ( 0 ), palladium chloride or palladium ( II ) acetate.
- The materials required for the production of the nanoshells are the following; Tetraethyl orthosilicate, ammonium hydroxide, hydroxylamine hydrochloride, 3-aminopropyl tris, hydrogentetrachloroaurate ( III ) trihydrate, tetrakis ( hydroxymethyl ) phosphonium chloride, sodium hydroxide, potassium carbonate, ethanol, Ultrapure water and glassware washed in aqua regia and rinsed thoroughly in water . :)
- Since all the six-membered rings in C 80-I h are equal This is evidenced by the presence of only two signals in the 13 C-silyl group in a reaction of Ce 2 @ C 80 with 1, 1, 2, 2-tetrakis ( 2, 4, 6-trimethylphenyl )-1, 2-disilirane.
- Commonly used crystal materials include LiF ( lithium fluoride ), ADP ( ammonium dihydrogen phosphate ), Ge ( germanium ), graphite, InSb ( indium antimonide ), PE ( " tetrakis "-( hydroxymethyl )-methane : penta-erythritol ), KAP ( potassium hydrogen phthalate ), RbAP ( rubidium hydrogen phthalate ) and TlAP ( thallium ( I ) hydrogen phthalate ).
- Recently, novel liquid organogermanium precursors, such as isobutylgermane ( IBGe ) and tetrakis ( dimethylamino ) germane ( TDMAGe ) were developed and used in conjunction with the metalorganics of antimony and tellurium, such as tris-dimethylamino antimony ( TDMASb ) and di-isopropyl telluride ( DIPTe ) respectively, to grow GeSbTe and other chalcogenide films of very high purity by metalorganic chemical vapor deposition ( MOCVD ).
- Rather, there are three perpendicular 2-fold axes . " D " 2 is a subgroup of all the polyhedral symmetries ( see below ), and " D " 2 " h " is a subgroup of the polyhedral groups T h and O h . " D " 2 can occur in homotetramers such as Concanavalin A, in tetrahedral coordination compounds with four identical chiral ligands, or in a molecule such as tetrakis ( chlorofluoromethyl ) methane if all the chlorofluoromethyl groups have the same chirality.
