Aluminium - Wikipedia

Aluminium visually reseles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27 Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26 Al is used in radiodating .

Metal-controlled interdomain cooperativity in parvalbumins

Therefore, the mechanism of the PA thermal denaturation is controlled by metal binding. It ranged from the absence of detectable first-order transition (apo-form of pike PA), to the two-state transition (e.g., Mg (2+)- and Na (+)-loaded forms of pike alpha-PA), to the more complex mechanisms (Ca (2+)-loaded PAs) involving at least one partially

Alloys | AMERICAN ELEMENTS

Five elements frequently found in refractory alloys include niobium, molybdenum, tantalum, tungsten, and rhenium. Common features that are shared among these metals are a melting point over 2000°C and high hardness at room temperature. Due to their high melting points, these metals are creep resistant at high temperatures.
