      Transmission Electron Microscope

      The transmission electron microscope (TEM) is a scientific instrument that uses electrons instead of light to scrutinize objects at very fine resolutions. They were developed in the 1930s when scientists realized that electrons can be used instead of light to "magnify" objects or specimens under study. TEMs provided a means to go beyond the magnification

    • Potassium Dichromate

      Potassium Dichromate

      Potassium dichromate (K2Cr2O7) is an inorganic chemical reagent that is normally used as an oxidizer in industrial and laboratory applications. It is used to oxidize alcohols and convert primary alcohols to aldehydes and sometimes carboxylic acids. Unlike similar processes that use permanganate, only carboxylic acids result. The secondary alcohols are converted into ketones and no

    • Fresnel Lens Projector

      Fresnel Lens Projector

      A projector is able to accomplish a projection with the help of a combination of lenses along with the other technical things. A Fresnel lens projector is one which has different Fresnel lenses placed in the projector. Fresnel Lens Fresnel lens was invented by a French physicist, Augustin-Jean Fresnel. These lenses have a large aperture

      What is a Pitot Tube?

      A pitot tube measures pressure levels in liquids. They are most commonly seen in laboratory settings but can be seen in industrial applications as small cylinders. While a pitot tube is not the only device that measures fluid pressure, it is capable of being implemented in much more diverse environments than similar devices. How Pitot

    • Infrared

      Infrared

      Infrared light is a form of electromagnetic waves. In its visible form, infrared can be seen as red or violet. Visible infrared waves are very short, measuring about 750 nm in length; longer infrared waves which are closest to microwaves are about 1mm in length. Infrared Waves While most infrared wave lengths give off heat,

    • How Safes Are Made

      How Safes Are Made

      Known under the generic name of safe or safe box there is a very broad set of constructions. From simple home safes used to keep personal documents, to bank safes which include special building construction and security measures. All safes are sturdy constructions made of metal (most with different layers) and a removable part (or

      U.S. Drones

      The U.S. drone program has seen significant press since the first Gulf War when the defenders of Faylaka Island surrendered to the Pioneer drone, or Unmanned Aerial Vehicle (UAV), flying spotting services for the USS Wisconsin (BB 64). Since that time, the technology powering U.S. drones has steadily improved now allowing the MQ-1B Predator and

    • How Do Rockets Work?

      How Do Rockets Work?

      Since the United States first landed a man on the moon, children and adults have been fascinated with how rockets work! Whether one is trying to fly a small model rocket or launching a star ship to rendezvous with the International Space Station, the principles of how rockets work remain the same. Although rocketry has

      What is a Peltier Cooler?

      A Peltier Cooler or Peltier Heat Pump is a type of refrigerator that has no moving parts and is capable of transferring heat to either side of itself. Peltier Coolers are advantageous as they are solid state devices and only require a DC electrical current in order to cool an object or area. A Peltier

    • RTV Silicone

      RTV Silicone

      Room Temperature Vulcanizing (RTV) silicone is a rubber polymer used to create molds, prototypes, and sealant. It is extremely flexible and quite tear resistant. It is made up of two separate components: a base and a curative. RTV silicone can be poured, sprayed, brushed, or pumped onto a surface. Either moisture or heat dries it,
