Galvanic corrosion occurs when two dissimilar alloys or metals come in contact with each other in a corrosive, conducting environment. When they touch, the anode metal corrodes faster than it would when submersed in the solution and the cathode metal corrodes much slower. Galvanic corrosion is not considered a bad quality, however, as the concept is commonly used in industry to protect more expensive metals by allowing less expensive ones to serve as anodes and be worn down instead. Why does Galvanic Corrosion Occur? When an electrolyte exists between two Read More

An Ultrasonic Pest Repeller is an electronic device that uses ultrasonic sound waves to repel insects, rodents, and other pests. Though humans are incapable of hearing these sounds, many animals, insects, and rodents can. There is much debate concerning the ultrasonic pest repeller’s ability to actually get rid of pests. While some people claim that ultrasonic pest repellers successfully rid their homes of pests, others argue that the device is only partially/temporarily effective or simply ineffective. How Ultrasonic Pest Repellers Work Ultrasonic pest repellers depend on ultrasonic frequencies to disturb Read More

The phases of the moon are caused by the location of the moon in relation to the Earth. In other words, as the moon rotates around the Earth, sun hits it in different angles and therefore, this causes the moon to undergo different phases. Based on the time of the month, the side of the moon that we see will experience more sunlight on it and then less sunlight. The Phases of the Moon When the moon "starts" its cycle of phases, it is known as a New Moon. This Read More

Nanoglue is a specially designed adhesive that is made to bond almost any kind of material that could be found today. It is mainly based on the concept of utilizing a substance that contains nanoscale chains capable of arranging or assembling themselves. Compared to other relevant materials, nanoglue tends to be cheaper to produce. In the instance that the nanoglue has been set, it would be able to withstand temperatures that are high enough to destroy or ruin other similar materials used in comparable applications. The said adhesive's molecular bonds Read More

Potassium is a mineral that is found naturally in many foods. It is one of the most important minerals as it helps the body to carry out many different functions, the most important being its use in the beating of the human heart. In some cases, it is difficult for people to get enough potassium in their body. For example, there are some diseases that result in low potassium levels. If an individual has been vomiting for some time, his/her potassium levels may decrease. There are also some medicines that Read More

Osseointegration is the connection between a living bone and the surface of an artificial implant, both functional as well as structural. Typically, titanium is used because it is an effective load-bearing implant. What it effectively does is allow for a prosthetic limb to fuse to the bone. When this occurs, it is as if the person (or animal) has a new limb rather than something connecting to the old limb. Since it is using titanium, the body won’t reject it because it is not interfering with the cells. While it Read More

A petabyte is a measurement unit that describes a piece of information that is equal to 1,000 terabytes or one quadrillion bytes of data. A single petabyte is equal to 1,000,000,000,000,000 bytes . When a petabyte describes computer memory, it is also used in reference to a corresponding power of 1024. The approved scientific symbol for the petabyte is PB. Pebibyte also describes a power of 1024 and is described through the symbol, PiB. Examples of Petabyte Use As computer data storage and network transmission capabilities continue to exceed the Read More

Metal detector technology has been used for a number of decades to locate various metallic artifacts and precious metallic ores. An uncommon, but accurate metal detector is the Pulse Induction Metal Detector. It uses Pulse Induction Technology to find metals. What is Pulse Induction Technology? In Pulse Induction technology, a coil is used as a transmitter and receiver. Pulse Induction metal detectors are likely to have a single coil, but there are others that have additional coils. Powerful pulses of current are sent through the coil. The pulses create magnetic Read More

One of the primary components of the oil that is extracted from the rind of citrus fruits is Limonene. When the juice is removed from a citrus fruit, the oil is also extracted from the rind, separate from the juice. The oil is then distilled so that flavor and other fragrance compounds can be removed from it. After this process is complete, the left over oil is called limonene or food-grade limonene. After the juicing process is completed, the peels are placed in steam extractors in order to harvest additional Read More

Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities. The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of increasing population, increasing amount of transportation vehicles and increasing urbanization. Intelligent highways are the new highway traffic analysis and response technology that will be implemented in major cities in the near future in order to Read More
