Block Copolymer

A block copolymer is defined as a polymer comprising molecules in which there is a linear arrangement of blocks, a block being defined as a portion of a polymer molecule in which the monomeric units have at least one constitutional or configurational feature absent from the adjacent portions.

Thorium Fuel Cycle



The thorium fuel cycle is the path that thorium transmutes through from fertile source fuel to uranium fuel ready for fission. Th-232 absorbs a neutron, transmuting it into Th-233. Th-233 beta decays to Pa-233 and finally undergoes a second beta minus decay to become U-233. This is the one way of turning natural and abundant Th-232 into something fissionable. Since U-233 is not naturally found but makes an ideal nuclear reactor fuel, it is a much sought-after fuel cycle. This fuel cycle is of extreme importance to molten salt reactors, as most of the proposed reactors could use the thorium fuel cycle.

Platinum-Group Metals



The platinum-group metals are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block. The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum.

Jet Engine Materials



The combustion chamber is also made of nickel and titanium alloys, and the turbine blades, which must endure the most intense heat of the engine, consist of nickel-titanium-aluminum alloys. Often, both the combustion chamber and the turbine receive special ceramic coatings that better enable them to resist heat.
