  • In modern usage, the term is used to describe devices capable of performing mechanical work, as in the original steam engine. In most cases the work is produced by exerting a torque or linear force, which is used to operate other machinery which can generate electricity, pump water, or compress gas. In the context of propulsion systems, an air-breathing engine is one that uses atmospheric air to oxidise the fuel carried rather than supplying an independent oxidizer, as in a rocket.

  • Volume 41 of the Handbook on the Physics and Chemistry of Rare Earths adds four chapters to the series: two focus on nanoscale rare-earth mate- rials, while the other two are concerned with divergent topics—the arrangement of the rare-earth elements in the periodic table, and the higher order rare-earth chalogenide compounds with the elements of the 14th group and also In. The first chapter (248) discusses the various proposals suggested for the location of the rare-earth elements in the periodic table from the time of Mendeleev to the present day.

  • 20 Sodium Sodium and potassium, being adjacent elements in Group 1 of the Periodic Table, have similar chemical properties. In the biology of higher organisms, however, these two elements have very different roles and are treated very differently by mechanisms involved in short- and long-range transport.

  • Inorganic chemistry is concerned with the chemical elements (of which there are about 100) and the extremely varied compounds they form. The essentially descriptive subject matter is unified by some general concepts of structure, bonding and reactivity, and most especially by the periodic table and its underlying basis in atomic structure.

  • Introduction Electronic Structure The platinum group metals occupy the second and third rows of periodic table Group VIII, the first row of which consists of iron (Fe), cobalt (Co), and nickel (Ni). The second-row elements ruthenium (Ru), rhodium (Rh), and palladium (Pd) all have the krypton (Kr, inert gas, atomic number 36) core of completed electron shells and subshells (see Chemistry, Electrochemistry, and Electrochemical Applications: Oxygen).

  • Introduction: It may seem something of a truism to describe an element as unique, but hydrogen is certainly one of the more unusual elements in the periodic table. It is the lightest element and consists of only a proton and an electron and is thus the only element not to contain a neutron in its main isotope (1H). In its stable molecular form (H2), it is also the least dense and the most abundant in the universe. Perhaps surprisingly, given that its low density results in gaseous hydrogen being almost nonexistent in the Earth’s lower atmosphere, it is also the...

  • Structural Characterization of Crystalline and Non-crystalline Materials – A Brief Background of Current Requirements The X-ray powder diffraction technique is a well-established and widely used method for both qualitative and quantitative analysis of various substances in a variety of states (see, for example, [1]). However, in a multi-component mixture with a relatively complicated chemical composition, we frequently find difficulty in identifying the individual chemical constituents by the conventional X-ray powder diffraction method.
