Tellurium - Element information, properties and uses ...
Tellurium is present in the Earth’s crust only in about 0.001 parts per million. Tellurium minerals include calaverite, sylvanite and tellurite. It is also found uncombined in nature, but only very rarely. It is obtained commercially from the anode muds produced during the electrolytic refining of copper.
Compounds of Tellurium
That the dioxide also has definite basic properties is shown by its reaction with many acids to produce salt-like compounds containing quadrivalent tellurium, as, for example, the tetrahalides and the sulphates. Tellurium trioxide, obtained by heating telluric acid, is unacted on by water, and is readily reduced to the dioxide.
What items contain tellurium - Answers
Nov 11, 2012 · tellurium The element that has 52 protons is tellurium, and the isotope of tellurium that has 76 neutrons is tellurium-128.
Metal Profile and Properties of Tellurium
History. Telluriums ability to form compounds with gold - a property that is unique to the metalloid - led to its role in Western Australias 19th-century gold rush. Calaverite, a compound of tellurium and gold, was misidentified as a value-less fools gold for a number of years at the beginning of the rush,...
TePhe, a tellurium-containing phenylalanine mimic, allows ...
Apr 23, 2019 · We developed L-2-tellurienylalanine (TePhe), an analog of phenylalanine that contains a tellurium atom, as a small-molecule probe for directly measuring protein synthesis quickly and in a wide range of contexts.
Synthesis of Tellurium-Containing π-Extended Aromatics ...
A synthesis of tellurium-embedded π-extended aromatics from tellurium powder and readily available cyclic diaryliodonium salts has been developed. The versatility of this method has been demonstrated by the synthesis of various functionalized dibenzotellurophenes (DBTe’s), a ladder-type π-system, and a heterosumanene.
Acute Tellurium Toxicity From Ingestion of Metal-Oxidizing ...
Aug 01, 2005 · Tellurium is an element used in the vulcanization of stone and in metal-oxidizing solutions to blacken or tarnish metals. Descriptions of human toxicity from tellurium ingestion are rare. We report the clinical course of 2 children who ingested metal-oxidizing solutions containing substantial concentrations of tellurium.
Selenium/tellurium containing polymer materials in ...
Selenium/tellurium containing polymers have been attracting growing interest due to their unique properties and potential applications as bio-nanomaterials. The introduction of selenium or tellurium chemistry into block copolymers endows self-assembled nanomaterials with novel stimuli responsiveness and enhanced sensitivity.
Tellurium-Containing Polymer Micelles: Competitive-Ligand ...
We report a competitive coordination system based on a novel tellurium-containing polymer and its ligand-regulated release manners. Tellurium was introduced to water-soluble polymers for the first time as drug delivery vehicles. The coordination chemistry between platinum and tellurium was designed to enable the load of platinum-based drugs.
