crystal lattice |

crystal latticeThree-dimensional configuration of points connected by lines used to describe the orderly arrangement of atoms in a crystal. Each point represents one or more atoms in the actual crystal. The lattice is divided into a number of identical blocks or cells that are repeated in all directions to form a geometric pattern. Lattices are classified according to their dominant symmetries: isometric, trigonal, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic. Compounds that exhibit a crystal-lattice structure include sodium chloride (table salt), cesium chloride, and boron nitride. See also solid-state physics. |

| The new findings indicate that this sluggish rate stems from a ball-and-chain effect: Traveling charges distort the organic materials' malleable crystal lattices and then have to drag around those distortions. These patterns of low and high light intensity serve as templates that mimic the molecular patterns of different crystal lattices. In the second paper, the chemists report assembling these positively charged building blocks (cations) and negatively charged compounds (anions) into crystal lattices they can control with an electrode. |
