Zeta Potential was composed in 2012 for the Nieuw Ensemble from Amsterdam, as part of the European Composers Professional Development Programme, led by Huddersfield Contemporary Music Festival. It is published by the University of York Music Press.

Zeta Potential is a calculation which measures the stability of semi-fluid/semi-solid substances; it indicates the potential for the material to remain in its present state.

Zeta Potential plays with the capability of the ensemble and texture to remain as a coordinated and stable system. The piece traces a constant flux between ‘solid’ and ‘fluid’ textures, framed around cycles of growing and decaying musical patterns which undergo constant transformation.
