A researcher whose team demonstrated control of <zinc oxide> <nanowire> shape by changing the solution chemistry during growth. Charged complexes preferentially adsorb on different crystal faces, slowing growth in selected directions. Changing additives and <pH> therefore changes the ratio of length to width, from plate-like crystals to needles. This supplies a physical mechanism for controlling structure through <electrostatic interactions> and <adsorption>, rather than relying only on a fixed growth recipe.<Face-selective electrostatic control of hydrothermal zinc oxide nanowire synthesis by Jaebum Joo and others>[Abstract and growth-inhibition model: face-selective adsorption, solution conditions and aspect-ratio control]{ref}
