Oxygen anion radicals are produced by the reaction of O2 molecule and electron (e-) from conduction band of the semiconductor. As the optimum pH is in acidic range, this super oxide anion radical will combine with proton forming HO2● radical. With the formation of more HO2● radicals, the rate of photocatalytic degradation of the dye increases. Above 7.0, a decrease in…

I. Science Fair Question What is the speed of light in gelatin? II. Background Research Did you ever wonder how the speed of light is measured? This paper will discuss how the speed of light is measured. The terms that will discussed in this paper are the law of refraction, trajectory, Snell’s Law, and the index of refraction. Snell’s Law gives the relationship between angles of incidence and refraction for a wave impinging on an interface between two media with…

Starbucks and Taiwan Semiconductor Manufacturing Company are both leaders in their respective fields. Starbucks is the market leader for specialty coffee shops and TSMC is the world’s largest dedicated semiconductor foundry. Both companies are strong today and are projected to have steady growth for the foreseeable future. This makes them healthy medium to long-term investments. These two companies operate in completely different markets and therefore the actions of either company do not affect…

In 1959, metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Dawon Kahng and Martin M. (John) Atalla at Bell Labs. Julius Edgar Lilienfeld had already patented the basic principle of this kind of transistor in 1925. But later the Bell Labs edition was allocated the name bipolar junction transistor, or merely junction transistor, and design of Lilienfeld came to be identified as field effect transistor. Later, Jean Hoerni found that Silicon dioxide (SiO2) should be used to…

Silicon carbide has been recognised as an important structural ceramic material because of its unique combination of properties. It is a promising ceramic material that can replace conventional metals and ionic-bonded oxide ceramics such as alumina. Structure of Silicon carbide Silicon carbide is a compound of silicon, a metalloid, and carbon, a nonmetal, and has a giant molecular lattice structure. It has a similar structure with diamond. Each carbon atom is joined tetrahedrally to four…

The open character, as discussed earlier, is a driving force for innovation in the semiconductor industry. This innovation, in turn, not only allows firms to be more competitive, but also more attractive. The firms are main attractions, if you will, are consumers and venture capitalists. The openness of these networks is integral to innovation…

Who should come first? Should company put costumers ahead of investors or put investors over costumers? Stereotypically, most people will think that a great businessman is the one who uses various strategies to grab consumer attention in order to gain the most profit for their companies. Yet, there are also businessmen like John Mackey, who believe that a great businessman is to put the costumers first over profit. However, businessmen John Rodgers disagree and argue that companies should come…

Throughout history there has been many amazing people who have impacted the world of science. From developing or innovating technology to discovering how life functions, they are all life changing contributions that make the world the way it is. One predominant aspect of today's daily life is technological devices; they can be found from pocket size, personalized gadgets to supercomputers used by governments or big corporations. It is difficult to imagine a world without technology, especially…
