Limonite (/ ˈ l aɪ m ə ˌ n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O , although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.
A slide is a single page of a presentation. A group of slides is called a slide deck. A slide show is an exposition of a series of slides or images in an electronic device or on a projection screen. Before personal computers, they were 35 mm slides viewed with a slide projector [1] or transparencies viewed with an overhead projector.
The DNi process uses nitric acid, instead of sulphuric acid, to extract the nickel within a few hours and then the nitric acid is recycled. The DNi process has the major advantage of being able to treat both limonite and saprolite lateritic ores and is estimated to have less than half the capital and operating costs of HPAL or Ferronickel ...
The video game Talking Points in The Jackbox Party Pack 7 is based on PowerPoint karaoke. One player presents a slideshow presentation created in real time by a second "assistant" player, using a user-generated title and provided transition phrases and pictures. A form of PowerPoint karaoke is frequently played in teams of two on Impractical ...
The changes between these levels are called "transitions" and are plotted on the Jablonski diagram. Radiative transitions involve either the absorption or emission of a photon. As mentioned above, these transitions are denoted with solid arrows with their tails at the initial energy level and their tips at the final energy level.
Allowed transitions must involve a change in parity, either g → u or u → g. For atoms s and d orbitals are gerade, and p and f orbitals are ungerade. The Laporte rule implies that s to s, p to p, d to d, etc. transitions should not be observed in atoms or centrosymmetric molecules.
