    • What Are Nanorobots?

      What Are Nanorobots?

      A nanobot is an extremely small robot that operates on a microscopic scale. Originally spoken of in science fiction circles, there has been an increased focus on it in biological and robotics research. The term nanorobot was created by combining the terms robot and nanometer. Other common names for robots of this size include nanobots,

    • What Causes Copper to Turn Green?

      What Causes Copper to Turn Green?

      Copper turns green because of a process known as oxidation which is the removal of electrons from the substance. Specifically, copper turns green because of something known as copper carbonate. This is the substance that is found on top of copper–whether they be copper pipes, pennies, statues or anything else. So, the cause of copper

    • What Fuels Are Used in Power Plants?

      What Fuels Are Used in Power Plants?

      There are many different types of power plants. Depending on the type of fuel someone wants to use determines what kind of power plant someone would build. The most powerful power plant is a nuclear power plant, but this is also the most controversial because of events such as Chernobyl and because it is difficult

    • Fraxel Laser

      Fraxel Laser

      Fraxel laser is a technology that is used for dealing with age spots, melasma (Mask of Pregnancy), sunspots, wrinkles at various parts of the face, upper lip lines, sun burned skin, and acne scars. Today it is the prime technology used for treating acne scars, as it barely creates any downtime. Initially developed and implemented

    • Acrylic Adhesives

      Acrylic Adhesives

      An acrylic adhesive is a resin-based adhesive that is comprised of acrylic or methylacrylic polymers. It is rather complicated to produce acrylic adhesives as they must be formed into a polymer, suspended in a catalyst, and cured. Acrylic adhesives are very strong and efficient at bonding multiple objects together. They are resistant to sunlight, not

    • How Laser Skin Tightening Works

      How Laser Skin Tightening Works

      Laser skin tightening is done through the use of lasers to tighten the old and “loose” skin to give the appearance of youthful skin. After the technology was changed in the early 1990s from the ablative technology to the non-ablative technology, the risk and the recovery times from the treatments have greatly lessened. Especially the

    • What is a Permeable Membrane?

      What is a Permeable Membrane?

      A membrane is a barrier that prevents entry of materials. Membranes can be permeable, which allows certain materials to go in and out of the barrier based on a variety of factors. Permeable Membrane in Biology In biology, a simple example of a permeable membrane is a cell wall. In both plant and animal cells,

    • The Kelvin Scale

      The Kelvin Scale

      The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed

    • 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

    • What Are Ferrofluids?

      What Are Ferrofluids?

      A ferrofluid is a metallic liquid that becomes magnetized when placed in a magnetic field. Ferrofluids are made up of clumps of iron nanoparticles that are evenly placed throughout a carrier fluid such as water or organic solvent. These clumps all work together to create a response to a magnetic field, consequently creating a very
