Chemistry for Information Science and Electrical Science

Chemistry that produces a voltage, and chemistry that destroys metal — which turn out to be the same chemistry running in opposite directions. The Nernst equation, the electrodes that make measurement possible, and why understanding corrosion as a galvanic cell tells you immediately how to stop it.

What modern devices are actually made of. Nanomaterials and why size alone changes properties, the carbon family from nanotubes to quantum dots, polymers that conduct, and the organic materials behind OLED displays and dye-sensitised solar cells.

How you find out what something is without taking it apart. Molecules absorb only the energies that match a transition they can make, so the pattern of absorption is a fingerprint — and the Beer-Lambert law turns that fingerprint into a concentration.

Water hardness and how it is measured and removed, the oxygen demand parameters that tell you whether a river is alive, sewage and e-waste treatment, and the chemistry behind climate change and ozone depletion.
