High‐pressure Nucleation of Low‐Density Polymorphs
, 2020 The crystallized above 0.3 GPa polymorphs β and γ of bis-3-nitrophenyl disulphide, are less dense than the ambient-pressure polymorph α. This high-entropy nucleation illustrates the molecular-scale mechanism of empirical Ostwald’s rule of stages.

Dual-gate low-voltage organic transistor for pressure sensing [PDF]
, 2017 We simultaneously achieved low voltage operation (-5 V) and large drain current (I_D) modulation in a dual-gate organic pressure sensor in which a piezoelectric layer was stacked on a low voltage organic field-effect transistor (OFET).
