Coupling between Ion Drift and Kinetics of Electronic Current Transients in MAPbBr3 Single Crystals
American Chemical Society (2022-03-11)The optoelectronic properties of halide perovskite materials have fostered their utilization in many applications. Unravelling their working mechanisms remains challenging because of their mixed ionic–electronic conductive ... -
Hysteresis in Organic Electrochemical Transistors: Distinction of Capacitive and Inductive Effects
American Chemical Society (2023-12-14)Organic electrochemical transistors (OECTs) are effective devices for neuromorphic applications, bioelectronics, and sensors. Numerous reports in the literature show persistent dynamical hysteresis effects in the current–voltage ... -
Interfacial Mechanism for Efficient Resistive Switching in Ruddlesden-Popper Perovskites for Non-volatile Memories
American Chemical Society (2020-01-16)Ion migration, one origin of current–voltage hysteresis, is the bane of halide perovskite optoelectronics. Herein, we leverage this unwelcome trait to unlock new opportunities for resistive switching using layered ... -
Introducing Ion Mobility Mass Spectrometry to Identify Site-Selective C–H Bond Activation in N-Heterocyclic Carbene Metal Complexes
American Chemical Society (2022-11-14)The activation of C−H bonds in a selective manner still constitutes a major challenge from a synthetic point of view; thus, it remains an active area of fundamental and applied research. Herein, we introduce ion mobility ... -
Methylammonium Lead Bromide Perovskite Battery Anodes Reversibly Host High Li-Ion Concentrations
American Chemical Society (2017-04)Ions migrate through the hybrid halide perovskite lattice, allowing for a variety of electrochemical applications as perovskite-based electrodes for batteries. It is still unknown how extrinsic defects such as lithium ions ... -
Molecular Basis of RNA-Driven ATP Hydrolysis in DExH-Box Helicases
American Chemical Society (2023-03-29)The spliceosome machinery catalyzes precursor messenger (pre-m)RNA splicing. In each cycle, the spliceosome experiences massive compositional and conformational remodeling fueled by the concerted action of specific ... -
Strongly Coordinating Ligands To Form Weakly Coordinating Yet Functional Organometallic Anions
American Chemical Society (2019-12-05)Weakly coordinating anions (WCAs) are generally tailored to act as spectators with little or no function. Here we describe the implementation of strongly coordinating dianionic carboranyl N-heterocyclic carbenes (NHCs) to ... -
Surface versus Bulk Currents and Ionic Space-Charge Effects in CsPbBr3 Single Crystals
American Chemical Society (2022-04-25)CsPbBr3 single crystals have potential for application in ionizing-radiation detection devices due to their optimal optoelectronic properties. Yet, their mixed ionic–electronic conductivity produces instability and hysteretic ...
