We developed an analog memristor based on the thickening/thinning of Ag nanofilaments in amorphous La1-xSrxMnO3 (a-LSMO) thin films. The Ag/a-LSMO/Pt memristor exhibited excellent pinched hysteresis loops under high excitation frequency, and the areas enclosed by the pinched hysteresis loops shrank with increasing excitation frequency, which is the characteristic typical of a memristor. The memristor also showed continuously tunable synapse-like resistance and stable endurance. The a-LSMO thin films in the memristor acted as a solid electrolyte for Ag(+) cations, and only the Ag/a-LSMO/Pt memristor electroformed with larger current compliance easily exhibited high-frequency pinched hysteresis loops. Based on the electrochemical metallization (ECM) theory and electrical transport models of quantum wires and nanowires, we concluded that the memristance is ultimately determined by the amount of charge supplied by the external current. The state equations of the memristor were established and charge was the state variable. This study provided a new analog memristor based on metal nanofilaments thickening/thinning in ECM cells, which could be extended to other resistive switching materials. The new memristor may enable the development of beyond von-Neumann computers.

In this paper, we report the results of the investigations on the transport properties performed across the manganite-manganite interface in the LaMnO3-δ/La0.7Ca0.3MnO3/LaAlO3 (LMO/LCMO/LAO) heterost...
Manganese is biogeochemically cycled between aqueous Mn(II) and Mn(IV) oxides. Aqueous Mn(II) often coexists with Mn(IV) oxides and redox reactions between the two (e.g., comproportionation) are well ...
Shear thickening is a widespread phenomenon in suspension flow that, despite sustained study, is still the subject of much debate. The longstanding view that shear thickening is due to hydrodynamic cl...

A disease of bone marked by thinning of the cortex and replacement of bone marrow by gritty fibrous tissue containing bony spicules, producing pain, disability, and gradually increasing deformity. Only one bone may be involved (FIBROUS DYSPLASIA, MONOSTOTIC) or several (FIBROUS DYSPLASIA, POLYOSTOTIC). (From Dorland, 28th ed)
