Beyond x-ray machines, ytterbium has a few other commercial uses. When ytterbium is added to steel, it can increase the strength of the metal.
The element is also used in metal alloys, and in portable x-ray devices. Some ytterbium isotopes generate gamma rays, which can be used to create a radiographic image of an object without the use of electricity. The purpose of this work is to explore the use of Ytterbium-169 as a source for cervical brachytherapy with the goal in increasing the ratio of the dose delivered to the tumor to the dose absorbed by surrounding healthy tissues. In particular, this work uses a Monte Carlo simulation Yttrium is rarely heard of. But it has some very important uses, especially in medicine. Find out what this substance is and what it is used for in and outside of the medical field.
Recently, we demonstrated a non-invasive technique based on an optical photon scanning tunneling microscope (PSTM) that can be used to "visualize" pulses

Ytterbium, named after a Swedish village, is another soft and bright silvery metal with various applications. Ytterbium-169 is a radiation source for portable X-ray machines and it is also used in nuclear medicine. Ytterbium is doped to stainless steel to enhance its mechanical properties. Ytterbium-169 | Yb | CID 105164 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety Se hela listan på en.wiktionary.org An atom of Ytterbium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Ytterbium. Yb + e – → Yb – – ∆H = Affinity = 50 kJ/mol. To use electron affinities properly, it is essential to keep track of sign.
Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster.A rare earth, the element is easily attacked and dissolved by mineral acids, slowly reacts with water, and oxidizes in air. What is YTTERBIUM? Ytterbium is a chemical element with symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series
Ytterbium is an element with the symbol Yb and the atomic number 70. It is a metal, variously described as either silvery or slightly yellowish, that is quite reactive yet stable in air. It is classified as a rare earth metal and a lanthanide, and behaves quite similarly to the other members of this group. Ytterbium is not found as a free metal in nature, but occurs with the other rare earths

Ytterbium-doped laser crystals and glasses have a number of interesting properties, which differ from those of, e.g., neodymium-doped gain media:.

It is a soft, malleable silvery metal that will tarnish slightly when stored in air and therefore should be stored in vacuum or in an inert The purpose of this work is to explore the use of Ytterbium-169 as a source for cervical brachytherapy with the goal in increasing the ratio of the dose delivered to the tumor to the dose absorbed by surrounding healthy tissues. In particular, this work uses a Monte Carlo simulation 2019-08-03 Definition of ytterbium : a soft metallic element of the rare-earth group that occurs especially with other rare earth elements in minerals and that has few commercial uses — see Chemical Elements Table Examples of ytterbium in a Sentence Ytterbium(III) oxide is the chemical compound with the formula Yb 2 O 3. It is one of the more commonly encountered compounds of ytterbium . It has the "rare-earth C-type sesquioxide" structure which is related to the fluorite structure with one quarter of the anions removed, leading to ytterbium atoms in two different six coordinate (non-octahedral) environments. Ytterbium oxides are available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in … Uses and properties John Emsley, Nature’s Building Blocks: An A-Z Guide to the Elements , Oxford University Press, New York, 2nd Edition, 2011.
