Directions for a Burning Bubbles Science Project

Directions for a Burning Bubbles Science Project Bubbles are fun no matter what, but bubbles you can burn just has that added extra appeal. Heres an easy science project you can do that proves propellants in common products are flammable and allows you to burn some bubbles. Materials for the Burning Bubbles Project Soapy water or bubble solutionSpray can containing a pressurized flammable propellantLighter or match (preferably long-handled)Cup or bowl A lot of the products you use that come in spray cans use a flammable propellant to disperse their product. Examples include hairspray, canned air, spray paint, antiperspirant, and bug spray. Common flammable propellants include various alcohols, propane, n-butane, methyl ethyl ether and dimethyl ether. You know you have a can containing a flammable product by reading the label. It will include a hazard statement warning you that the contents are under pressure and to keep the can away from heat and flame and that the contents are flammable. Some cans use non-flammable carbon dioxide or nitrous oxide as a propellant (whipped cream and cooking sprays), which wont work for this project. Once you have identified a flammable propellant, one fire-related project is to spray the product and ignite the aerosol, creating a sort of flamethrower. This is not particularly safe. Blowing flammable bubbles and igniting them illustrates the same point without the risk of blowing up a pressurized ca n. Blow Bubbles and Burn Them Pour soapy water or bubble solution into a container.Immerse the nozzle of the can in the liquid.Spray the can, forming bubbles.Remove the can from the liquid and set it a safe distance from the container.Ignite the bubbles, preferably using a long-handled lighter. Do you see why it would be a bad plan to smoke while using hairspray? The effect you get depends on the flammable propellant. The flames dont last long enough (at least in my experience) to set off a smoke alarm or melt a plastic container. Safety Warning This is one of those projects which should only be attempted under adult supervision. Do not get carried away and blow a big mass of bubbles. Igniting flammable materials is associated with risk. Use of proper eye and skin protection is advised.

Overview of OLED Technology

Overview of OLED Technology OLED stands for organic light-emitting diode and its cutting edge technology results from many innovations in display monitors, lighting, and more. As the name suggests, OLED technology is the next-generation advance of regular LEDs and LCDs, or liquid crystal displays. LED Displays Closely related LED displays were first introduced to consumers in 2009. LED television sets were much thinner and brighter than their predecessors: plasmas, LCD HDTVs, and, of course, the humongous and outdated CRTs, or cathode-ray tube displays. OLED displays were introduced commercially a year later, and allow for even thinner, brighter, and crisper displays than LED. With OLED technology, completely flexible screens that can fold or roll up are possible. Lighting OLED technology is exciting because it is a viable and functional innovation in lighting. A lot of OLED products are light panels whose large areas diffuse lighting, but the technology lends itself well to different applications like the ability to change shape, colors, and transparency. Other benefits of OLED lighting compared to traditional alternatives includes energy efficiency, and the lack of poisonous mercury. In 2009, Philips became the first company to manufacture an OLED lighting panel called Lumiblade. Philips described the potential of their Lumiblade as thin (less than 2 mm thick) and flat, and with little heat dissipation, Lumiblade can be embedded into most materials with ease. It gives designers almost limitless scope to mold and meld Lumiblade into everyday objects, scenes and surfaces, from chairs and clothing to walls, windows and tabletops. In 2013, Philips and BASF combined efforts to invent a lighted transparent car roof. It will be solar powered, and will turn transparent when switched off. Thats just one of many revolutionary developments possible with such state-of-the-art-tech. Mechanical Functions and Processes In the simplest of terms, OLEDs are made from organic semiconductor materials that emit light when an electrical current is applied. OLEDs works by passing electricity through one or more incredibly thin layers of organic semiconductors. These layers are sandwiched between two charged electrodes–one positive and one negative. The â€Å"sandwich† is placed on a sheet of glass or other transparent material which, in technical terms, is called a â€Å"substrate†. When current is applied to the electrodes, they emit positively and negatively charged holes and electrons. These combine in the middle layer of the sandwich to create a brief, high-energy state called â€Å"excitation†. As this layer returns to its original, stable, â€Å"non-excited† state, the energy flows evenly through the organic film, causing it to emit light. History OLED diode technology was invented by researchers at the Eastman Kodak company in 1987. Chemists Ching W. Tang and Steven Van Slyke were the principal inventors. In June 2001, Van Slyke and Tang received an Industrial Innovation Award from the American Chemical Society for their work with organic light-emitting diodes. Kodak released several of the earliest OLED-equipped products, including the first digital camera with a 2.2-inch OLED display with 512 by 218 pixels, the EasyShare LS633, in 2003. Kodak has since licensed its OLED technology to many companies, and they are still researching OLED light technology, display technology, and other projects. In the early 2000s, researchers at Pacific Northwest National Laboratory and the Department of Energy invented two technologies necessary to make flexible OLEDs. First, Flexible Glass an engineered substrate that provides a flexible surface, and second, a Barix thin film coating that protects a flexible display from harmful air and moisture.
