    • What Are Photonic Crystals?

      What Are Photonic Crystals?

      Photonic crystals are those that manipulate how photons are absorbed or reflected off of them. They occur in nature and are made of dielectric nanostructures that allow certain wavelengths to pass through them while blocking other wavelengths. The visible light portion of the electromagnetic spectrum’s wavelengths is responsible for colors, therefore photonic crystals can spontaneously

    • Torsional Vibration

      Torsional Vibration

      Solid mechanics defines torsion as the twisting of an object as a result of applied torque. Torsional vibration can be broadly described as the angular vibration of any object. It can be defined specifically as the periodic motion corresponding to a shaft, where the shaft is twisted about its axis, alternating from one direction to

    • Oxygen Generators

      Oxygen Generators

      An oxygen generator is a device that produces oxygen on demand, usually through the use of inorganic reactions. There are several types of oxygen generators but each depends on thermal reactions to produce oxygen. This causes the generator to become very hot, between 500 and 1,200 degrees Fahrenheit, and can present a serious fire hazard

    • The Peltier Effect

      The Peltier Effect

      The Peltier effect is one of the three separately identified effects to which “Thermoelectric Effect” or simply, “Thermoelectricity” refers. The other two are the Seebeck and Thomson effects. Discovery This effect is named after French physicist Jean-Charles Peltier, who discovered it in 1834. Peltier found that the junctions of dissimilar metals were heated or cooled

    • Vehicle Platooning

      Vehicle Platooning

      Vehicle platooning is one of the innovations in the automotive industry that aim to improve the safety, efficiency, mileage, and time of travel of vehicles while relieving traffic congestion, decreasing pollution and reducing stress for passengers. One of the recent demonstrations of this technology was during the PATH program done in California by 8 Buicks

    • What is Neuromarketing?

      What is Neuromarketing?

      Neuromarketing is a field of marketing that involves studying the way people react to marketing techniques and adjusting those techniques to maximize sales and inform the public about a specific product, idea, or campaign. Neuromarketing includes the use of biometric sensors, social studies, and subliminal messaging. While neuromarketing is a relatively new technique, it has

    • What Causes Optical Illusions?

      What Causes Optical Illusions?

      In simple terms, an optical illusion is caused by the structure of both the eye and brain and how they work together. Because of the anatomical make up of the eye and the complexity of the way images of transmitted from the eye to the brain, optical illusions are not as rare as one might

    • What is a Laser Profilometer?

      What is a Laser Profilometer?

      A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser technology in order to improve the degree to which a surface

    • What Happens During Photosynthesis?

      What Happens During Photosynthesis?

      Photosynthesis is the process that plants, some bacteria, and some animals use to convert light energy and other sources into sugar and other essential proteins that they need to survive. This article will go over how photosynthesis works and the many different aspects of this process. We will talk about photosynthetic membranes, light reactions, solar

    • Throttle Position Sensor

      Throttle Position Sensor

      A throttle position sensor is a device that can detect a difference in throttle position. The Engine Control Unit (ECU) uses throttle position sensors in internal combustion engines to gauge the throttle’s position as well as the rate of change in the throttle’s position in order to relay this information to other devices in the
