"The atomic structure of C-S-H can be optimized by changing the ratio of joints, or atoms, versus sticks, or the chemical constraints acting between the atoms," explains University of California, Los Angeles Assistant Professor Mathieu Bauchy, Ph.D., who is visiting the MIT Department of Civil and Environmental Engineering and assisting in CSHub nanoscience applications.

Crystallography to infinity and beyond: William Henry Bragg moved from Cambridge in Britain to South Australia to take up a professorship at the University of Adelaide in 1885. He brought with him a broad interest in many areas of physics, but when Wilhelm Roentgen discovered X-rays in the 1890s Bragg's interest was stimulated
Since the Sn[S.sub.2] of different morphologies possess different predominant facets, the surface atomic structure and thus electronic structure are supposed to play a more deciding role in the different activities.
