Cadmium

     Home | cadmium | Cadmium



Cadmium (c-eniconˈkædmiəm ) is a chemical element with the symbol Cd and atomic number 48. This soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Similar to zinc, it prefers oxidation state +2 in most of its compounds and similar to mercury it shows a low melting point compared to transition metals. Cadmium and its congeners are not always considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of cadmium in the Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate.

Cadmium occurs as a minor component in most zinc ores and therefore is a byproduct of zinc production. It was used for a long time as a pigment and for corrosion resistant plating on steel while cadmium compounds were used to stabilize plastic. With the exception of its use in nickel-cadmium batteries and cadmium telluride solar panels, the use of cadmium is generally decreasing in its other applications. These declines have been due to competing technologies, cadmium’s toxicity in certain forms and concentration and resulting regulations. Although cadmium is toxic, one enzyme, a carbonic anhydrase with cadmium as reactive center, has been discovered.

What is Glazing? The technical answer is 1.) multiple thin layers of transparent oil paint (applied at the end of a painting)....but what I want YOU to remember is 2.) Glazing is pure magic 3.) Knowing how to glaze will take your painting abilities to the next level. 1.) Why glazing is an important painting strategy 2.) (We will touch a little bit on) The science of refracted light 3.) Which paints to use. (How can you tell if a paint is a glazing color?) 4.) Which brushes to use for glazing 5.) How to do it! (The technique of glazing oil paint) Glaze layers happen at the final stages of a painting, so lets take you to the end of the painting that you just saw right now. I am going to keep things concise and to the point. Give me your full attention for the next few minutes and you will acquire a solid understanding of glazing. 1- Why is glazing an important painting strategy? Think about the last time that you had a sunburn. When sunburns heal, a layer of skin usually peels off your body. Take a second to remember what that skin looks like. The peel of skin is very thin, smooth and it is possible to see light through it. Our outermost layers of skin, the epidermis, is comprised of multiple layers of skin similar to the peeled layer of skin that you just imagined. Glazing, the application of multiple, thin, transparent to translucent layers, is like the epidermis of a painting and it is important for an artist to know how to glaze so that he or she can get a more life <b>...</b>

If you'll excuse the ridculously overdramatic soundtrack :) Synthesis of CdSe nanocrystals by injection of cadmium and selenium precursors into a high boiling point coordinating solvent at 360 degrees C. ~3nm particles of CdSe are initially generated. The intense color results from the quantum confinement effect on the electron as a result of the nanocrystal size being less than the Bohr radius of the exciton. Thus, as the particles grow larger, they become redder in color. A size series was generated by allowing the crystals to grow at 280C over a period of ~2 minutes. The visible spectrum from 515nm (green) to 650nm (red) was covered.

April 1980 www.amazon.com Watch more clips: thefilmarchived.blogspot.com Project MK-ULTRA, or MKULTRA, was the code name for a covert CIA mind-control and chemical interrogation research program, run by the Office of Scientific Intelligence. The program began in the early 1950s, continuing at least through the late 1960s, and it used United States citizens as its test subjects. The published evidence indicates that Project MK-ULTRA involved the surreptitious use of many types of drugs, as well as other methods, to manipulate individual mental states and to alter brain function. Project MK-ULTRA was first brought to wide public attention in 1975 by the US Congress, through investigations by the Church Committee, and by a presidential commission known as the Rockefeller Commission. Investigative efforts were hampered by the fact that CIA Director Richard Helms ordered all MK-ULTRA files destroyed in 1973; the Church Committee and Rockefeller Commission investigations relied on the sworn testimony of direct participants and on the relatively small number of documents that survived Helms' destruction order. Although the CIA insists that MK-ULTRA-type experiments have been abandoned, 14-year CIA veteran Victor Marchetti has stated in various interviews that the CIA routinely conducts disinformation campaigns and that CIA mind control research continued. In a 1977 interview, Marchetti specifically called the CIA claim that MK-ULTRA was abandoned a "cover story." On the Senate <b>...</b>

This is amazing to see an anchor man describing the 'clouds' seen by weather satellite photographs as MILITARY CHAFF. Close my friend, but what your marine corps training failed to mention that they contain Aluminium, Cadmium and other highly toxic substances!
