First Bulk Nanostructured Metal,t textbooks of the time would not dare to venture opinions. The subject has calmed over a period of about half a century, so much so that the theory can be used to create materials that fire the imagination. The story is illustrated here.

Dazzling Diamonds Grown from Gases, of gift that might seal a relationship between humans. However, their utility spans well beyond their dazzle. Diamonds are the hardest of natural materials, have a high thermal conductivity that if five times that of copper. There are therefore a myriad of engineering applications, such as in high-

Stirring Solid Metals to Form Sound Welds,ring welding and yet is able to fabricate structurally sound joints. A robust spinning-tool rubs against the abutting parts that require joining, generates heat by friction, thus softening the metals without melting it. The translation of the spinning-tool along the joint line forges the pieces toge

Inventions that Enabled the Silicon Age,n with extreme purity, with less than one foreign atom per ten million of silicon. There are innovative processes that have enabled the mass production of such silicon. The base for discussion is the silicon that has been made since the nineteenth century for metallurgical applications, where the de
