    • Anodizing Aluminum

      Anodizing Aluminum

      Anodizing/anodized aluminum refers to both a specific type of aluminum alloy as well as the process that is used to produce this alloy. The term “anodizing” is used to describe a technique for expanding the natural oxide layer of metals, especially aluminum. Anodizing changes the texture of aluminum by creating a much more porous surface

    • What is a Plasma Cutter?

      What is a Plasma Cutter?

      A plasma cutter is a device that directs an ionized gas at an object under extreme temperatures. Plasma cutters are often used for industrial purposes, such as cutting metal, and are dependent on plasma, an extremely hot state of matter. Plasma cutters are essentially a type of plasma torch meant for cutting metal rather than

    • How Laser Hair Removal Works

      How Laser Hair Removal Works

      Laser hair removal, as its name suggests, is using a laser to remove any hair that is unwanted. The majority of the process is done with a thin light beam of laser passing through the area of the skin that is being treated. Within the skin, specifically the dark pigment, also known as the melanin

    • Linear Actuator

      Linear Actuator

      A linear actuator is a mechanical device that makes a linear motion, usually via a hydraulic pump or electromagnetic gear. Other forces can be used to create linear motion. The different types of linear actuators include screw, wheel and axle, cam, hydraulic pump, pneumatic, piezoelectric, and electro-mechanical. Linear motors, wax motors, and telescoping linear actuators

    • Potassium Perchlorate

      Potassium Perchlorate

      Potassium Perchlorate (Potassium Chlorate (VII), perchloric acid, potassium salt, peroidin, and KClO4) is an inorganic salt that is used as a strong oxidizer. The function of potassium perchlorate’s oxidizer trait really depends on the chemical use. Potassium Perchlorate can be found in the following common items: Fireworks – Fireworks have many chemical compounds inside them,

    • Nanopollution

      Nanopollution

      Nanopollution refers to the waste matter or byproducts of nanoscopic device or material manufacture. Nanoscopic device or material manufacturing processes leave behind nanoparticles (smaller than a billionth of a meter) which can infiltrate the cells of humans, animals and all living organisms that may be unprepared for the influx of artificial particles. A 1941 study

    • 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.

    • Fluorescence Spectroscopy

      Fluorescence Spectroscopy

      In the field of spectroscopy, fluorescence can be analyzed from a sample of material through a special form of electromagnetic spectroscopy. This fluorescence spectroscopy uses a beam of light that is tailored for the type of fluorescence detection needed in compounds. The usual option is an ultraviolet light that is used to excite electrons in

    • Earth Cooling Tubes

      Earth Cooling Tubes

      Earth cooling tubes present an alternative for controlling temperature within residential and office buildings as well as greenhouses and other structures requiring temperature regulation. These tubes run underground and alter air’s cooling or heating temperature before it is allowed into a home or office. En route, the air releases its heat to the surrounding soil

    • How Fast Does the Earth Spin?

      How Fast Does the Earth Spin?

      One of the basic questions regarding the earth is, how fast does it spin? The earth is constantly spinning; it spins around its axis. An axis in this case is an imaginary line running through the center of the earth from the North Pole to the South Pole. To calculate how fast the earth spins,
