Despite extensive efforts, the crystal structure of none of the higher aluminium borides has so far been solved.

WE have made X-ray diagrams of aluminium-copper alloys (5 per cent Cu) age-hardened at various temperatures (25°–200° C.) ; the samples were composed of large crystals, and the radiation was ...

It has a melting temperature of 660 C. The electronic configuration of Aluminum is (Ne)(3s) 2 (3p) 1, and it has an atomic radius of 0.143 nm. At room temperature Aluminum has the face-centered-cubic ...

Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the ...

Therefore, there are eight tetrahedral holes inside each cube. Since the stoichiometry of the salt is 2:1, we must fill all of the tetrahedral holes (the FCC structure gives four selenides, thus we ...

Zeolite is a natural mineral that possesses a unique structure carrying a negative charge. This particular characteristic allows it to attract and retain positively charged ions and molecules ...
