Xerographic spectroscopy of gap states
... In the sensitization-exposure part of the xerographic cycle, as illustrated in Fig. 1.4, a photoreceptor film mounted on a grounded substrate is charged to a voltage V0 by corona then completely photodischarged by exposure to strongly absorbed light (absorption depth δ << L). Both the top corona con ...

... Generally, the ion, (cation or anion) with smaller size and more charge will have greater lattice energy. Born-Haber's cycle: The basis for Born-Haber's cycle is Hess's law. It states that the heat energy change will remain constant whether a chemical reaction occurs in one step or several steps. ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
