The sneak path problem is one of the major hindrances to the application of high-density crossbar resistive random access memory; however, complementary resistive switching (CRS) is an effective solution to this problem. The co-existence of resistive switching (RS) and CRS is possible within the same device. Therefore, a precise control is highly required for the successful utilization of different modes. In this study, we have demonstrated an effective way to control both switching modes in a simple HfO-based crossbar device. The interchange between RS and CRS modes is possible, based on the intrinsic anionic rearrangement by controlling the extrinsic stimulation, either in the form of voltage or in the form of current. In particular, a highly nonlinear CRS mode is reported, in which the nonlinearity is almost 100 times greater than in the RS mode, which is achieved at a high temperature of 150 °C. The procedure reported in this study may be useful for the other resistive memory systems.

Aquaporin 1 (AQP1) is a key channel for water transport in peritoneal dialysis. Inhibition of AQP1 could therefore impair water transport during peritoneal dialysis. It is not known whether inhibition of AQP1 occurs unintentionally due to off-target interactions of administered medications.

Elucidating the charging mechanism plays an intrinsic and critical role in the development of high-performance supercapacitors; however, a deep understanding of how this mechanism varies under different charging rates remains challenging. In this study, we investigate the charging mechanism of conductive metal-organic framework (c-MOF) electrodes in ionic liquids, combining electrochemical quartz crystal microbalance and constant-potential molecular dynamics simulations. Both experimental and modeling results reveal a transition of the ion adsorption and desorption modes from anion dominance at low charging rates to ion-exchange governance at high charging rates, significantly reducing the contribution of anions to the capacitance.

Ammonia borane (NHBH, AB) is considered a promising chemical hydrogen storage material. The development of efficient, stable, and economical catalysts for AB hydrolysis is essential for realizing the hydrogen energy economy. In this study, a series of p-p heterojunction catalysts, labeled M (P/S/Cl)-CuCoO, were fabricated using the high-temperature vapor phase method to achieve anionic interface gradient doping.

The design of cathode/electrolyte interfaces in high-energy density Li-ion batteries is critical to protect the surface against undesirable oxygen release from the cathodes when batteries are charged to high voltage. However, the involvement of the engineered interface in the cationic and anionic redox reactions associated with (de-)lithiation is often ignored, mostly due to the difficulty to separate these processes from chemical/catalytic reactions at the cathode/electrolyte interface. Here, a new electron energy band diagrams concept is developed that includes the examination of the electrochemical- and ionization- potentials evolution upon batteries cycling.

Oxygen vacancies in Ruddlesden-Popper (RP) perovskites (PV) [AO][ABO] play a pivotal role in engineering functional properties and thus understanding the relationship between oxygen-vacancy distribution and physical properties can open up new strategies for fine manipulation of structure-driven functionalities. However, the structural origin of preferential distribution for oxygen vacancies in RP structures is not well understood, notably in the single-layer ( = 1) RP-structure. Herein, the = 1 RP phase SrNdZnO was rationally designed and structurally characterized by combining three-dimensional (3D) electron diffraction and neutron powder diffraction.
