Miniaturization Miniaturization Miniaturization (Br.Eng.: "Miniaturisation") is the trend to manufacture ever smaller mechanical, optical and electronic products and devices. Examples include miniaturization of mobile phones, computers and vehicle engine downsizing. In electronics, Moore's law, which was named after Intel co-founder Gordon Moore, predicted that the number of transistors on an integrated circuit for minimum component cost doubles every 18 months. This enables processors to be built in smaller sizes. The history of miniaturization is associated with the history of information technology based on the succession of switching devices, each smaller, faster, cheaper than its predecessor.

Bent's rule carbon and the R group. As s orbitals have greater electron density closer to the nucleus than p orbitals, the electron density in the C−R bond will more shift towards the carbon as the s character increases. This will make the central carbon more electron-withdrawing to the R group. Thus, the electron-withdrawing ability of the substituents has been transferred to the adjacent carbon, exactly what the inductive effect predicts. Bent's rule provides an additional level of accuracy to valence bond theory. Valence bond theory proposes that covalent bonds consist of two electrons lying in overlapping, usually hybridised, atomic orbitals from
