Non‐volatile Sliding Ferroelectric Memory Effect in Ultrathin γ‐InSe

open access: yesAdvanced Electronic Materials, EarlyView.
Room‐temperature sliding ferroelectricity in γ‐InSe enables a two‐dimensional FeFET with a 6.8 V memory window, above 104 conductance modulation, longer than 10‐years retention and above 103 cycles fatigue resistance. An ultrathin (4.8 nm) γ‐InSe ferroelectric tunnel junction exhibits reversible high/low resistance switching with TER of 105 at room ...

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

open access: yesAIChE Journal, EarlyView.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG$$ {c}_{\mathrm{AG}} $$. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation.
