the samples in the loading chambers of the supporting matrix which was made of one percent agarose gel. GelRed, a nucleic acid dye, was added to help visually identify the DNA bands. A power supply was added to the gel for 20 minute by placing an anode (positive poled) at the bottom and a cathode (negative poled) at the top. PCR clean-up was tested using the same electrophoresis method as the DNA extraction. PCR A portion of DNA from the extraction was amplified using polymerase chain…

In designing our science fair project, many concepts and variables are to be considered. Our science fair project is experimenting on how rust forms so research and prior knowledge is required before we actually conduct the experiment. Having previous information on the topic allows us to be able to alter the variables accurately when we actually administer the procedure. For our project, we are exploring the idea of the formation of rust and how the lack of or extra variables could affect the…

the electrolyte and sugar content of that drink. Electrolytes are positively or negatively charged ions that are essential for survival. Positively charged electrolytes move towards a cathode, while negatively charged electrolytes move towards an anode. There are many kinds of electrolytes that can be found in the body. The electrolytes that can be found in the body are the following: • Sodium (Na+) • Potassium (K+) • Chloride (Cl-) • Calcium (Ca2+) • Magnesium (Mg2+) • Bicarbonate…

This paper will discuss about "the Hall-Heroult Process" history, process, and the two scientists that created this process. The Hall-Heroult process came to be in 1886 in the race of commercially viable route to aluminum by two men working independently, who are Paul Heroult and Charles M. Hall who was assisted by his sister Julia Brainerd Hall. The Hall-Heroult process is the process for smelting aluminum that involves dissolving the aluminum oxide in molten cryolite and electrolysis the…

When photons hit the electrons in the top plate, it gives the electrons energy to flow to the bottom plate and this shift in electrons creates an electrical current. These reactions for the solar cells themselves are denoted in different layers. The anode side is denoted with 2H2 => 4H+ + 4e-. The cathode side is denoted with O2 + 4H+ + 4e- => 2H2O. The net reaction is denoted with the equation 2H2 + O2 => 2H2O Pollution comparison: energy from the sun is…

corrosion in micro electric circuits. Generally most of the IC’s applied voltage between conductors is 5-10 V. However, in the presence of sufficient adsorbed moisture on the dielectric, the fraction of the applied voltage that appears across the anode/substrate and cathode/substrate interfaces can be sufficient to sustain an electrochemical reaction. Frankenthal and his co-workers studied the behavior of gold in sulfate solutions containing various amounts of chloride. They found that active…

These contents of these tubes are in a vacuum (no air inside), where the tube contains two oppositely charged electrodes - one on each side. One of the electrodes (the cathode) fires electrons at the other (the anode) when voltage is added to the system. When Thomson turned the tube on, he saw a beam of "light" between the two electrodes. To figure out what this “light” was, he applied a magnetic field to the contents of the tube and found out that the beam moved…

ABSTRACT In this work, a new flexible and transparent substrate with the help of organic materials such as Polydimethylsiloxane (PDMS) and Tetra ethoxy orthosilicate (TEOS) is synthesized. Transmittance of about 90-95 % is obtained in the visible region (400-700 nm) and the synthesized substrate show better thermal characteristics and withstands temperature upto 200 oC without any significant degradation. Characteristics such as transmittance (T), absorption (A), refractive index…

Case study of X-ray imaging with grating interferometer on pearls Abstract- With the increase of fraudulent conduct in the field of jewellery there has been increase in the demand for inspection to identify the purity of the product. In this case study X-Ray Radiography is used to identify natural pearls and artificially cultured pearls. In order to understand the internal structure a personalized grating interferometer and inspection has been performed to obtain measurements. The computed…

machine on and off, without a functioning one the machine cannot work. On the inside of the x-ray tube there is a filament or a cathode emitter, which are used to generate accelerated electrons. When the electrons are generated they move to the metal anode which has a current flowing through which is powered by the high voltage power source. After an electron beam is created the beam hits a focal point and it turns into x-ray photons. After this the photons flow in different directions and the…
