gray

Examples of gray in the following topics:

• The Payne Rearrangement

  • The first diagram below illustrates three such reactions, and a general mechanism is written in the gray-shaded box.
  • The course of reaction in the absence of the Payne rearrangement is displayed in the gray-shaded box.

• Measuring Radiation Exposure

  • Dose is reported in gray (Gy) for matter or sieverts (Sv) for biological tissue, where 1 Gy or 1 Sv is equal to 1 joule per kilogram.
  • Define the terms used to define radiation exposure, the gray (Gy) and sievert (Sv)

• Silicate Units, Silicate Chains, Silicate Sheets

  • Ball-and-stick model of the silicate tetrahedron; red represents oxygen atoms and gray represents the silicon atom in the center.
  • Red balls correspond to oxygen, and gray to silicon atoms.

• Photochemistry

  • Several secondary radical reactions then follow (shown in the gray box), making it difficult to assign a quantum yield to the primary reaction.

• Grob Fragmentation

  • The non-ethylagous analog for the reaction is drawn in the gray-shaded box.

• Ionic Radius

  • The neutral atoms are colored gray, cations red, and anions blue.

• Crystal Structure: Packing Spheres

  • Calcium ions are depicted as gray spheres, and fluorine ions are yellow.

• Steelmaking and Refining

  • Henry Cort's original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges.
  • For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.

• Pericyclic Reactions

  • All these reactions are potentially reversible (note the gray arrows).

• Carbon-Carbon Bond Formation

  • The structure of this compound is shown in the gray box at the upper left of the first diagram below.
