    • 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

    • How Does a Segway Work?

      How Does a Segway Work?

      A Segway is a vertical, mobile vehicle that is able to carry a single person between distances. While a bicycle consists of two wheels and a horizontal frame, a Segway consists of two or four wheels and a vertical frame that balances atop these wheels to steady the rider. Segways run on purely electrical energy

    • 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 Do Electric Motors Work?

      How Do Electric Motors Work?

      As society is trying to slowly ween itself off of oil-dependency, the search for alternative fuels continues. One source of alternative "fuel" that already exists, however, is the electric motor. Electric motors are commonly found in vehicles, toys, and other electronic devices but there is still a campaign to improve the quality and efficiency of

    • 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

    • How a MagLev Train Works

      How a MagLev Train Works

      MagLev Trains are trains that rely on magnets or magnetic force to run. There are different kinds of MagLev Trains that have been developed and they differ on the technology used to attract the magnetic force or magnets to make the train run or levitate. Each project is developing its own version of Magnetic levitation

    • 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

    • DNA Fingerprinting

      DNA Fingerprinting

      DNA fingerprinting is the process of taking a cell sample from a person and analyzing it. This technique involves analyses of less than 0.1% of human DNA (which is different for each person). Though small, this 0.1% of DNA is enough to distinguish one individual from another and can be used to determine maternity/ paternity

    • Electromotive Force

      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • Brain Computer Interface

      Brain Computer Interface

      A brain computer interface (BCI) is an external devices that communicate directly to the brain of humans or animals through neuron silicon interfaces. These external devices can either transmit or receive signals to and from the brain which can then be used to restore function or movement to sensory organs or limbs. Furthermore, these external
