... because both the film thickness and the PEC performances were more reproducible. The plating bath was a 0.2 M CuSO4 (Sigma Aldrich) and 3 M lactic acid (Fisher Scientific) solution in deionized (DI) water with 0.5 M K2HPO4 (Sigma Aldrich) buffer. The given concentrations refer to the plating solutio ...

... compression but weak in tension. This means it is very hard to change their shape, but they are easily snapped. They are electrical and thermal insulators and have very high melting points. They are chemically unreactive and do not react with oxygen, water or acids. Ceramics are crystalline compound ...

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.
