      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,

    • How Do Zambonis Work?

      How Do Zambonis Work?

      In the world of ice hockey and ice skating, there is nothing more important than maintenance of the ice. Failure to properly take care of an ice rink could result in broken bones, property damage, or the loss of a game. In order to efficiently care for an ice rink, ice rink owners spend large

    • How a Nuclear Bone Scan Works

      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.

    • Alpha Particles

      Alpha Particles

      What are Alpha Particles? An alpha particle is a type of ionizing radiation that is exerted from radioactive materials. Alpha particles consist of two neutrons, two protons, and no electrons, giving it a net positive charge. This positive charge allows the alpha particles to leave their nucleus and bombard any nearby items with radiation. Alpha

    • Long Range Acoustic Device

      Long Range Acoustic Device

      The LRAD or the long range acoustic device that has been developed by American Technology Corporation is capable of emitting a maximum of 151Db sound within 30 degrees of where the device is pointing. This device can be used as a combatant deterrent weapon or crowd-control device by emitting sounds that are painful to the

    • Potassium Chlorate

      Potassium Chlorate

      Potassium chlorate is a chemical compound that contains chlorine, oxygen, and potassium. In its pure form, it is white and crystalline in appearance. It is the most common chlorate used in industry, school, research, and commercial labs. Potassium chlorate is commonly used: to prepare oxygen, in safety matches, as an oxidizing agent, in fireworks and

    • PIR Sensor

      PIR Sensor

      A PIR (Passive Infrared) sensor detects infrared light that is emitted from objects within its field of view. PIR sensors differ from other infrared sensors because they can only receive infrared waves. Because all objects emit infrared waves (electromagnetic waves that travel with heat), PIR sensors can detect objects that are in front of them.

    • Pharming

      Pharming

      Pharming is a process whereby plants and animals are genetically modified to become carriers of genes that stimulate the production of substances that have useful pharmaceutical applications. Thus, the term pharming is actually a play on the words pharmaceuticals and farming. To explain the process in simple terms, a foreign gene is introduced into the

    • Holographic Memory

      Holographic Memory

      Holographic memory is a storage device that is being researched and slated as the storage device that will replace hard drives and DVDs in the future. It has the potential of storing up to 1 terabyte or one thousand gigabytes of data in a crystal the size of a sugar cube. Brief History of Holographic

    • What Are Ionic Compounds?

      What Are Ionic Compounds?

      An ionic compound is any compound in which an electrostatic force holds the ions together. Ionic compounds are made of positively charged particles that rest against negatively charged particles in order to balance out the two particles’ magnetic imbalance. They can be found in both solid and liquid states, although solid ionic compounds are poor
