      What is a Monostable Multivibrator?

      A multivibrator is a device that changes between two states and its own design or an external force powers it. For example, a weight that is placed on a suspended spring will extend the spring to its maximum length as gravity weighs down on it. When the spring is stretched to its maximum length, however,

      What is Mossbauer Spectroscopy?

      Mossbauer Spectroscopy is a multipurpose technique that is applied in various scientific fields including Physics, Biology, and Metallurgy. It is most useful in deriving accurate data about the chemical, structural, and magnetic properties of a material. This technique exists today due to the discovery of the resonant absorption and recoil-less emission of nuclear y-rays, now

      Types of Nuclear Fuel

      The different nuclear processes will use different types of fuel. In general terms: Fission reactions will use fissile heavy elements Fusion will use fusible light elements The convection point is iron. Elements heavier that iron will have higher mass than its parts and yield energy when they break apart. Lighter elements that iron will have
