"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.
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.
In a reversal of the convention where biomimetics offer ideas from biology for engineering developments, the atomic structure of this NLC material has caused researchers to revisit the tentacles of the octopus to explain its abilities.
With the expert help of science teacher Andy Smith, the students used lab experiments to investigate the basic atomic structure of a squib, how it relates to the production of coloured light and the physics of making the precise shape of the explosion.
Rutherford revolutionized scientists' understanding of atomic structure and relativity.
Aims for the laser include that it will help scientists to film chemical reactions and examine the atomic structure of molecules.
Subjects range from life cycles and organisms for elementary learners to atomic structure and chemical bonding for high school students.
We developed a classification scheme, and examined 95 websites that teach atomic structure. The results show that advanced communication means and graphical tools are rarely used.
