Chapter 8 Notes
... Lattice energy increases with decreasing ionic radii. This makes sense if you think about it. After-all the smaller the ion, the closer the positive nucleus is to the valence electrons responsible for bonding. So Magnesium compounds will have higher (negative) lattice energies than Calcium compounds ...

Nanofluidic circuitry
Nanofluidic circuitry is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic counterparts. Its typical characteristic dimensions fall within the range of 1–100 nm. At least one dimension of the structure is in nanoscopic scale. Phenomena of fluids in nano-scale structure are discovered to be of different properties in electrochemistry and fluid dynamics.
