When Barbara Bowen was planning for retirement, she took pains to get her house in order. Chief among her projects was replacing the cedar-shake roof on her 1970s' Walnut Creek home. After careful ...

Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that repeat the same exact pattern, over and over again. But there's a well-known ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

Hidden semiconductor defects often pass inspection but fail later in operation. Learn how latent defects form, evade detection, and drive long-term reliability failures.

(Nanowerk News) From blacksmiths forging iron to artisans blowing glass, humans have for centuries been changing the properties of materials to build better tools - from iron horseshoes and swords to ...

A new study helps to reconcile a Nobel Prize-winning theory with experiments on how solids actually melt. In 1972, physicists J. Michael Kosterlitz and David Thouless published a groundbreaking theory ...
