Correlated Charge Transport in an Organic Coulomb Glass
Advanced Materials, EarlyView.ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Time-frequency and instantaneous frequency concepts
, 2016 This chapter provides an extended in-depth treatment of the material described in Chapter I. It focuses on the precise description of the key concepts and formulations needed to formally describe time-frequency (t, f) methods. Section 1.1 describes in detail the justifications why time-frequency methods are preferred for a wide range of applications ...

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Tough and Rapidly Relaxing Hydrogels Via Programmable Crosslink Kinetics
Advanced Materials, EarlyView.A kinetic programming strategy encodes supramolecular crosslink lifetimes in single polymer networks via stoichiometric control of fast and slow hostguest interactions. This enables predictable stress relaxation on biologically relevant timescales (0.1‐100 s) while maintaining exceptional toughness (up to 14,500 J m−2), resolving the long‐standing ...

Advanced Materials, EarlyView.ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...
