      What is Photoelectron Spectroscopy?

      Photoelectron spectroscopy is the study of energy and how it relates to matter in terms of absorption and production. Photoelectron spectroscopy observes both wavelengths and frequencies and is used to view the physical composition of chemicals and solids. It is used in both analytical and physical chemistry and astronomy in order to study an object’s

      Types of Robots

      A robot is a mechanical or virtual artificial agent that software, hardware, or firmware programming controls/guides. Most robots today are programmed to complete tasks on their own or via human direction. No longer a product of science fiction, there are a number of industries today that use of various types of robots. These include the

    • Throttle Position Sensor

      Throttle Position Sensor

      A throttle position sensor is a device that can detect a difference in throttle position. The Engine Control Unit (ECU) uses throttle position sensors in internal combustion engines to gauge the throttle’s position as well as the rate of change in the throttle’s position in order to relay this information to other devices in the

    • Molality

      Molality

      Molality is the number of moles in a solute per kilogram of solvent. It is often confused with the term molarity, which is an alternative unit for concentration that measures the number of moles of solute per liter of solution. Molality is commonly used when experiments require significant temperature changes. This is because a solute’s

      How a Nuclear Bone Scan Works

      In the last several decades, medical technology has advanced in leaps and bounds. One of the most advanced technological instruments used in medicine today is the nuclear bone scan. A nuclear bone scan uses a radioactive tracer and high-resolution camera to identify areas of new bone growth or areas in which bone has broken down.

      Pill Identification Numbers

      Many of us require medication for optimum health and this usually leads us to the pharmacist where we pick up our medicine in the form of pills. As the months and years go by our medicine cabinets become full with a variety of different pills for a host of ailments. Sometimes we no longer know

    • Types of Nuclear Fuel

      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

      What is Electrotherapy?

      Electrotherapy is a medical technique in which an electric current is used to perform a wide variety of tasks associated with pain, neurological disorders, muscle-related conditions, and drug delivery. Electrotherapy includes a range of medical techniques, some of which are under much debate and criticism. While electrotherapy itself is an accepted form of medical treatment,

      MRI Video Goggles

      MRI video goggles were designed to assist Magnetic Resonance Imaging (MRI) patients from experiencing the effects of claustrophobia by providing 3d video and audio. The goggles immerse the patient DVD video and audio assisting them in avoiding the uncomfortable feeling and mental anxiety of being in a very small contained area for a period of

    • Electromagnets

      Electromagnets

      Electromagnets are magnets whose magnetic properties come from or are generated through electricity. A magnet is a material (this is usually metal), which has at least one pair of negative and positive poles. These opposite poles' attraction produces a magnetic field. This gives the magnet the ability to 'attract' metals such as iron or steel.
