Porous organic crystals with superior properties as CO2 adsorbents were created by researchers at Institute of Science Tokyo.

This is due to the shape of the molecule. Water molecules are polar molecules ... Carbon tetrachloride has four polar covalent bonds. It is a tetrahedral molecule, so the charges are symmetrical.

Many of the familiar properties of water that result in its behavior in soils can be directly related to its molecular structure. Aa Aa Aa "Water is the driving force of all nature." - Leonardo da ...

After extensive experimentation, they uncovered foldable molecular paths ... materials, the tetrahedral zinc centers within ZIFs function as hinges, enabling the structure to fold and adapt ...

Having 'solved' the structure of polyglycine II in August ... it was shown to be correct. "Molecular models of biological polymers — reliable, hand-built models — were not wide spread at ...
