Novel indium-mediated radical cyclization reactions of aliphatic iodoalkynes have been studied. Treatment of iodoalkynes with a catalytic amount of In (0.1 equiv) and I2 (0.05 equiv) promotes atom-transfer 5-exo cyclization to give five-membered alkenyl iodides. In contrast, reaction with In (2 equiv) and I2 (1 equiv) yields reductive 5-exo cyclization products via the same 5-exo cyclization.

the oxide, alumina, occurs naturally as ruby, sapphire, corundum, and emery, and is used in glass making and refractories. Synthetic ruby and sapphire are used in the construction of lasers; The analysis of base metals in industry is naturally important and ideally achieved in the field with robust equipment.
Batman dives to the bottom of a huge tank and used a stethoscope to determining that the criminals are hiding out under its floor. After rounding up the fish and draining the tank, Batman and Robin access the hideout through a "latch," that looks suspiciously like a "hatch" to me, and haul out the criminals.

There are three sets of Indium halides, the trihalides, the monohalides, and several intermediate halides.In the monohalides the oxidation state of indium is +1 and their proper names are indium(I) fluoride, indium(I) chloride, indium(I) bromide and indium(I) iodide.. The intermediate halides contain indium with oxidation states, +1, +2 and +3.

The analysis of a curious metal ornament found in the tomb of Chou-Chu, a military leader in 3 rd century China, turned out to be 85% aluminium. How it was produced remains a mystery. By the end of the 1700s, aluminium oxide was known to contain a metal, but it defeated all attempts to extract it.
Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine, in a sense, is "radiology done inside out" or "endoradiology" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays.

Niobium metal has a number of important uses. It is a component of some stainless steels and also alloys with nonferrous metals. These alloys have good strength and other properties, and are used in pipeline construction. The metal has a low capture crosssection for thermal neutrons and so finds use in the nuclear industries.
