In Chemistry, Neodymium is one of the 118 elements found on Mendeleev’s Periodic Table. An element is a substance that is made entirely from one type of atom and is then advantageously placed in the periodic table which categorizes all elements of the universe. Neodymium was discovered to have a “twin element” and is used for anything from high-powered fans to cellular phones. For years scientists tried to pull the compound Didymium apart but without success. Triumph hit the city of Vienna in 1885
ceramic magnets, alnico magnets, neodymium magnets, and samarium cobalt. Ceramic magnets contain iron oxide in a ceramic composite and are the ones used in refrigerators. Ceramic magnets, also known as ferric magnets, are fairly weak. Alnico magnets are made of aluminum, nickel, and cobalt. Alnico magnets are much stronger than ceramic magnets, but are not stronger than magnets that contain rare-earth metals. Neodymium magnets contain iron, boron and neodymium. Neodymium is a rare-earth metal. Samarium
magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic, such as iron, and attracts or repels other Magnets Types of commercial magnets: Neodymium magnets: Neodymium Iron Boron (NdFeB).This type of magnet is composed of rare earth magnetic material, and has a high coercive force. They have an extremely high energy product range, up to 50 MGOe. Because of this high product energy level, they can
Transport- The issue of transportation and the environment is somewhat of a paradox. Transportation conveys certain socioeconomic benefits, but transportation is also effecting environmental systems. Positively, transportation supports the increasing need of mobility for passengers and freight, while negatively, transport is tied to motorizations, congestion on transport lines, and the growing lists of environmental externalities. Since the Industrial Age, humans have been rapidly changing their

Laser commonly Known as Light Amplification by Stimulated Emission of Radiation. Laser is a phenomena in which a very narrow or thin beam of intense electromagnetic radiation i.e. light is emitted. Laser Beam Welding (LBW) is a welding technique or method used to join or link up pieces of metal with the help of a laser technology. The beam provides a concentrated/focused heat(infrared) source, allowing for narrow, deep, precise welds and high welding accuracy. The process is frequently/often used
What is a body image? Are body images good or bad? Does everyone have a body image? According to the Oxford Dictionary, a body image is the subjective picture or mental image of one's own body. Body images can be good or bad, depending on many things such as a person’s self-esteem and how others perceive someone. Everyone does have a body image, it doesn’t matter if they are black, white, pink, or blue; young, old, or somewhere in between; boys, girls, and anyone else, we all have a certain way we

On this Reflective Journal I would consider and try to apply my studying on daily day and future plan. Corporate Social Responsibility build a business to last by business to behave ethically and contribute to
When you were young, you may have remembered about trying to make objects stick together or move things, like metal paperclips, just by using a magnet. Back then, you probably thought that magnets’ only exist as play things. But, now that you’re older, you’ve realised that these objects play a significant role in day-to-day life. In fact, everything that works around you makes use of the magnetic field. Although you cannot see it, you can be aware of it if you observe your surroundings. Magnets can
ABSTRACTS The limitation occurs during uses of non-renewable resources day by day, we want to go for renewable energy source. As we can see that with uses of non-renewable source its exhaust every day, and its increase pollution. we can decrease that by increase the use of renewable sources. Solar, tidal, wind which are renewable sources, they can generate electricity without any pollution. We also worked on another type of source, it is something which can generate electricity without any constant

I. Introduction The external environment of organisations is closely related to the survival and development of organisations. This report addresses external forces and conditions of enterprises and how do they affect the organisations. It will have PEST Analysis Module and Michael Porter’s Five Forces Model. It will use these two analysis module to analyse the impact of the external environment on the company, as well as some case will in this report are used to study how to use these analysis module
Lithium is used in many items we use daily, but it may not be the best for us to use (Wanger 202-206). Lithium’s effects can be sorted into the categories; political, economic, environmental, social, and technological. Of these the economic and environmental are the most important to understand. The environmental and economic effects can connect to social, political, and technological effects. We should stop using lithium batteries because the effects will add up and create problems for our society
other minerals like silver and copper are relatively scarce, and the recent economic and population growth rapidly accelerated the exploitation and consumption of these minerals(Miller & Spoolman, 2009:p.360). Moreover, some minerals (terbium and neodymium) are hard to extract because there are not many rich profitable deposits, meanwhile, they are highly
magnets. Need for bonded tools in diamond industry have increased the demand for Cobalt powder. 6. Substitutes Cobalt is used in specialized applications and is difficult to be substituted. Potential substitutes include barium or strontium ferrites, neodymium iron- boron or nickel-iron alloys in magnets; nickel, cermets or ceramics in cutting and wear-resistant materials; nickel-based alloys or ceramics in jet engines; nickel in petroleum catalysts; rhodium in hydroformylation catalysts; and cerium, lead
Rare earth elements allow for the conveniences shared by modern society. It is the critical components that have made the advancements in technology possible. Its versatility expands thought different media that include: renewable energy, geographic information systems, national security, missile guidance, computer technology, hybrid vehicles, plastics, medical technology and more. All population throughout the world use it regardless if they know it or not. The mining and process of rare earths
0006% thorium as opposed to 0.00018% uranium. Almost all thorium found in the Earth’s crust is thorium 232 - the desirable kind for a reactor. The major source of the thorium extracted is from monazite phosphate. Monazite phosphate contains cerium, neodymium, lanthanum, and of course phosphorus and oxygen. Monazite phosphate is typically 3-5% thorium dioxide. Most of the world’s current demand for thorium comes from Malabar Coast in india where monazite is deposited. Extracting the thorium from the monazite
Earth is at risk of losing all of it’s fresh water and rare metals. People have become very accustomed towards the availability of resources at their disposal that they do not realize that very soon these resources will run out. Earth’s most valuable resources are being abused in order to provide for the entire population that it currently holds. This problem needs to be resolved before it is too late. Recently, scientists and astronomers have discovered that these resources are actually located
In 2007, the world consumed 5.3 billion tons of coal, 31.1 billion tons of oil, 2.92 trillion cubic meters of natural gas, and 65,000 tons of uranium. All of these energy needs could have been met with only 6,600 tons of thorium, an abundant, slightly radioactive element found in the Earth’s crust. We depend on energy; nothing in our daily lives could be possible without it. Electricity primarily comes from burning fossil fuels or using nuclear reactors. But the plain truth is, we are running out
CO2 laser is the standard type of laser for the transoral endoscopic laryngeal surgeries. Diode laser devices have the advantage of being relatively less expensive, lighter in weight and smaller than most other medical lasers. They require less maintenance and can be portable. They have the advantage over the CO2 laser of being readily delivered through fibers allowing easy use with endoscope to reach subglottic and tracheal lesions when needed. 21,22,29-31,35,37,200 CO2 laser produces invisible
