SQA CfE Higher Chemistry Unit 1: Chemical Changes and Structure
... All substances are made up of particles called atoms, ions or molecules, and these particles are constantly moving. The degree of movement depends upon the state of the substance. This is known as the "kinetic model" of matter. In any sample of solution, liquid or gas there is a range of kinetic ene ...

Correlation between Crystal Structure and Mobility in Organic Field
... We studied seven different TTF derivatives, which are shown in Figure 1, namely bis(ethylenedithio)-tetrathiafulvalene (BEDTTTF), (ethylenethio)(ethylenedithio)-tetrathiafulvalene (ETEDTTTF), bis(ethylenethio)-tetrathiafulvalene (BET-TTF), (ethylenethio)(thiodimethylene)-tetrathiafulvalene (ETTDM-TT ...

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.
