  • On the Mechanism of the Dissolution of Quartz

    Quartz and silica are common materials, and their dissolution is of significant interest to a wide range of scientists. The kinetics of the dissolution of quartz and silica have been measured extensively, yet no clear theory of dissolution is available. A novel theory of dissolution and crystallization has recently been proposed that envisages the removal of material from the surface to form

  • Orders of magnitude (mass) - Wikipedia

    The table below is based on the kilogram (kg), the base unit of mass in the International System of Units ().The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name.The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a "kilokilogram".
