Dysprosium
Dysprosium is a chemical element with the symbol Dy and atomic number 66. It is a rare earth element with a metallic silver luster. Dysprosium is never found in nature as a free element, though it is found in various minerals, such as xenotime. Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is 164Dy.
Dysprosium was first identified in 1886 by Paul Émile Lecoq de Boisbaudran, but was not isolated in pure form until the development of ion exchange techniques in the 1950s. Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications, and as a component of Terfenol-D. Soluble dysprosium salts are mildly toxic, while the insoluble salts are considered non-toxic.
Characteristics
Physical properties
Dysprosium is a rare earth element that has a metallic, bright silver luster. It is soft enough to be cut with a knife, and can be machined without sparking if overheating is avoided. Dysprosium's physical characteristics can be greatly affected by even small amounts of impurities.

Isotopes of dysprosium
Naturally occurring dysprosium (Dy) is composed of 7 stable isotopes, 156Dy, 158Dy, 160Dy, 161Dy, 162Dy, 163Dy and 164Dy, with 164Dy being the most abundant (28.18% natural abundance). Twenty-nine radioisotopes have been characterized, with the most stable being 154Dy with a half-life of 3.0 million years, 159Dy with a half-life of 144.4 days, and 166Dy with a half-life of 81.6 hours. All of the remaining radioactive isotopes have half-lives that are less than 10 hours, and the majority of these have half-lives that are less than 30 seconds. This element also has 12 meta states, with the most stable being 165mDy (t1/2 1.257 minutes), 147mDy (t1/2 55.7 seconds) and 145mDy (t1/2 13.6 seconds).
The primary decay mode before the most abundant stable isotope, 164Dy, is electron capture, and the primary mode after is beta decay. The primary decay products before 164Dy are terbium isotopes, and the primary products after are holmium isotopes.
Relative atomic mass: 162.500(1).

Dysprosium Curie Point Demonstration
I show how the element Dysprosium becomes magnetic when added to liquid nitrogen. Many people have been asking how it gets the energy to run, I've been thinking about this and I believe that it gains its energy from the increase in entropy as the nitrogen boils into a gas while cooling the metal. The cooling decreases the entropy of the metal allowing it to be attracted by the magnet and do work, but Since the gas is escaping the system and increasing the entropy of the universe, it does not violate thermodynamics. Sorry about the audio, Ive looked into it and its not getting any better, I'll see If I can do the next video differently.

Dysprosium Superconductivity Eliminating Resistance to Progress
Superconductivity -- Eliminating Resistance to Progress In recent years, government regulations on fuel economy have sparked huge changes in the automobile industry, and it is only one of the first of many American industries which will be pushed to reduce CO2 emissions and total energy use as America strives for a greener future. While significant advances have been made in promoting reusable energy sources, the day when all energy produced is renewable is, in all likelihood, far away. Accordingly, a solution is needed which will allow American individuals and industries to consume far less energy in their lives without changing their habits. Such a solution would need to reduce energy use in many areas of society. Superconductors -- materials in which no electrical resistance is pre...

Magnetic Salt - Dysprosium Nitrate
We demonstrate the magnetic properties of dysprosium nitrate. Dysprosium nitrate is paramagnetic and is thus attracted to a magnetic field. The salt itself is clear with a beige/yellow tinge and is thus quite unusual among common magnetic materials that are usually opaque or metallic. By itself dysprosium isn't very useful but can adjust the magnetic properties of other materials and is therefore very useful to make the components of motors, actuators and hard drives.

Pure dysposium is a gray metal. My sample is pretty old and has covered in gray oxide layer. Dysprosium is a pretty expensive metal and it costs about 20 dollars on ebay. Its physical properties are not that much different from other lanthanides although I have began to question that. For instance a Wikipedia article about the metal in English says that the metal is very soft and that it can even be sliced with a knife. Hm, let us check. I can’t cut it with a knife although it’s possible to cut off a small piece. Probably my sample is just fragile because of its porous structure but it can’t be cut with a knife that is why it is always check if the information is true. Also dysprosium gets attracted to a powerful neodymium magnet quite well, of course not as good as iron. Nevertheless, dysprosium is paramagnetic at room temperatures but if frozen to the temperature of liquid nitrogen it can become ferromagnetic. This property of the metal has applications in a special alloy called terfenol-d the formula of which you can see on your screen. This alloy has a unique property called magnetostriction. To put it simply, if a pole made of this alloy is inserted inside a copper wire coil and alternating current is passed through it, such a pole will be slightly lengthening upon magnetizing and shortening upon demagnetizing. In an alternating magnetic field the pole can quickly change its length and make vibrations that can turn into music! This is where this property of terfenol-d is used - in vibration speakers.

Superconductivity -- Eliminating Resistance to Progress
In recent years, government regulations on fuel economy have sparked huge changes in the automobile industry, and it is only one of the first of many American industries which will be pushed to reduce CO2 emissions and total energy use as America strives for a greener future. While significant advances have been made in promoting reusable energy sources, the day when all energy produced is renewable is, in all likelihood, far away. Accordingly, a solution is needed which will allow American individuals and industries to consume far less energy in their lives without changing their habits. Such a solution would need to reduce energy use in many areas of society. Superconductors -- materials in which no electrical resistance is present, and therefore can carry current without loss, present a possible means toward this end. In addition to the advances in power transmission that loss-free current could provide, superconductors also can be used to make extremely powerful, low energy electromagnets. This means that superconductors present a method by which electric motors may be drastically improved, and by which frictional personal transportation energy losses may be drastically reduced, as is the case today in experimental superconducting Mag-Lev trains.
Unfortunately, the method which is used in the Japanese SC-MAGLEV trains today is not feasible for use in roadways, as the superconducting materials used in these systems only operate at temperatures around -170 degrees Celsius, and therefore require a constant supply of liquid nitrogen for cooling. This method was only made possible recently, by a ceramic (Yttrium barium copper oxide), as well as several similar ceramics, that have been discovered and demonstrate superconductivity at temperatures above the boiling temperature of liquid nitrogen. These materials therefore allow for superconductivity at a much lower cost than previous under 10 degrees Kelvin, and required liquid Helium cooling. Despite this huge benefit, these materials still could be improved. By finding ways to produce materials that are superconductors at even higher temperatures, the potential cost and complexity of such systems could be further reduced. The ways in which these material improvements can be attained can be understood through basic knowledge of what allows for superconductivity. In superconductive metals, superconductivity can be explained as a sudden transformation in which all of the electrons change at the quantum mechanical level, and move together through the material as one entity, without any resistance. In ceramics, however, this theory fails, and superconductivity is still not fully understood. What engineers do know is that the key to increasing the critical temperature at which the ceramics enter the superconducting state is found in increasing the density of CuO2 planes within the material, as well as increasing grain size. Currently, engineers are using complex heat treatments and combinations of elements to attempt to increase this plane density. If they find greater success, this could result in a material with superconducting properties at room temperature, which would make possible "superconducting highways", loss-free power transmission, and lightweight electric motors.
