Gold is a chemical element with Au as its symbol. It belongs to group 11, periodic number 6 of the periodic table. Its atomic number is 79.
Bismuth iodide is an inorganic compound with the chemical formula BiI3. It occurs as gray-black solid and adopts a distinctive crystal structure having iodide centers at a hexagonally closest-packed lattice. It forms upon heating the mixture of bismuth and iodine powder.
Arsenic trisulfide is an inorganic compound with the chemical formula As2S3. It occurs in a bright yellow mineral named as orpiment and a red-orange mineral called as realgar.
Silicon carbide is a compound of silicon and carbon with the chemical formula SiC. It occurs in the extremely rare mineral moissanite. Silicon carbide grains are bonded together by sintering to form hard ceramics that are used in applications requiring high endurance.
Uranium dioxide is an oxide of uranium produced by reducing uranium trioxide with hydrogen. It is a black, radioactive, crystalline powder that naturally occurs in the mineral uraninite. It is capable of withstanding high temperatures of about 2300°C and resistant to radiation damage.
Zinc oxide is an inorganic compound with the chemical formula ZnO. It occurs as a white powder that is nearly insoluble in water. It crystallizes in two main forms, hexagonal wurtzite and cubic zincblende.
Mercury (II) iodide is a chemical compound that exists in red-orange crystals. It is highly reactive to lead salts, iodoform, chlorides, light, heat, hydrogen peroxides and copper salts. Unlike mercury (II) chloride, it is hardly soluble in water.
All that time spent playing with plastic bricks as a kid may finally be paying off, as tiny composite blocks developed by MIT have been used to create a lightweight structure and could lead to much more design freedom in composite manufacturing.
