A primary function of the leafâs waxy cuticle is to reduce water loss through the leaves, which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall.
The first plant designed for rolling aluminum foil was opened in 1910. Aluminum foil replaced tin foil, when the Dr. Lauber, Neher & Cie., Emmishofen aluminum foil rolling plant in Kreuzlingen, Switzerland, was opened by J.G. Neher & Sons.
In 1899 Ernest Rutherford studied the absorption of radioactivity by thin sheets of metal foil and found two components: alpha (a) radiation, which is absorbed by a few thousandths of a centimeter of metal foil, and beta (b) radiation, which can pass through 100 times as much foil before it was absorbed.
