Invited for the cover of this issue is the group of Andrzej Katrusiak at Adam Mickiewicz University. The image depicts a wave and the sun, which represent the high energy required for the high-entropy nucleation reported in this work.

New polymorphs β and γ of bis-3-nitrophenyl disulphide, crystallized above 0.3 GPa, are less dense than the ambient-pressure polymorph α. This counterintuitive density relation results from the high-entropy nucleation and subsequent kinetic crystallization. The work performed by pressure compensates the high entropy and temperature product, substantiated in varied conformers and increased chemical potential. Pressure-increased viscosity promotes the kinetic polymorphs, in accordance with empirical Ostwald's rule of stages. It contrasts to mechanochemical techniques, favouring high-density polymorphs., (© 2021 The Authors. Published by Wiley-VCH GmbH.)
