    7. Dimension 3 DISCIPLINARY CORE IDEASEARTH AND SPACE SCIENCES. E arth and space sciences (ESS) investigate processes that operate on Earth and also address its place in the solar system and the galaxy. Thus ESS involve phenomena that range in scale from the unimaginably large to the invisibly small.

  • Recent achievements in facilitated transport membranes

    INTRODUCTION. Membrane separation processes have been used for many applications in the chemical industry, given the compactness, simple and efficient operation and low energy consumption of membranes (Hagg, 1998).

  • Minerals, Rocks & Rock Forming Processes

    Minerals in the Earth's Crust. There are more than 3000 known minerals (the number is still growing), but of these only about 20 are very common, and only 9 of these constitute 95% of the crust.These 9 minerals are all silicates, and are also called the rock forming minerals.They can be subdivided into two groups, the mafic and felsic minerals according to the principal rocks

  • Chemical substance Wikipedia

    A chemical substance, also known as a pure substance, is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be chemical elements, molecules, chemical compounds, ions or alloys.. Chemical
