Resistive memory is one of the most promising candidates for next-generation nonvolatile technology due to its variety advantages, such as simple structure and low-power consumption. Bipolar resistive switching behavior was observed in epitaxial ZnO nanoislands with base diameters heights ranging around 30 40 nm, respectively. All four different states (initial, electroformed, ON, OFF) nanoscale memories were measured by conductive atomic force microscopy immediately after voltage sweeping...
Oxygen vacancy (Vo) is believed to control the switching mechanism of metal oxide resistive memory. However, an accurate and quantitative theory prove this point view remains absent. In letter, we propose a model combining Poole-Frenkel effect, space charge limited current, modification Vo density simulate current-voltage curves. The calculated results show reasonable agreements with experimental data, which indicates that between high resistance state low in devices Al/ZnO/p+-Si led by...
Abstract Potassium ion batteries (PIBs) have aroused intensive research interest owing to their abundant source, low cost, and suitable working potential. Here, a V 2 C‐VO nanoribbon intertwined nanosheet 3D multi‐heterostructure with rich heterointerface heterojunction is fabricated via facile solution‐based method for realizing highly flexible robust anode material of PIBs. The co‐existence in the constituent individual generates heterojunctions heterointerfaces this hetero‐dimensional...
The gravimetric, areal, and volumetric capacities pose important influences on market penetration for secondary batteries. Carbonaceous materials take a leading stand the improvement of gravimetric areal capacity in lithium–sulfur batteries; however, they exhibit some intrinsic deficiencies, including insufficient fixation lithium polysulfides (LiPS) low tap density, incurring poor performance inferior cycling behavior. Here, we report sulfur cathode based highly conductive ZrB2 nanoflakes...

Resistive memory has attracted a great deal of attention as an alternative to contemporary flash memory. Here we demonstrate interesting phenomenon that multimode resistive switching, i.e. threshold-like, self-rectifying and ordinary bipolar can be observed in one self-assembled single-crystalline ZnO nanoisland with base diameter height ranging around 30 40 nm on Si at different levels current compliance. Current-voltage characteristics, conductive atomic force microscopy (C-AFM)...
An analytical approach is provided for describing the resonance properties of optical nanoantennas made a stack homogeneous disks, i.e., circular patch nanoantennas. It consists in analytically calculating phase accumulation surface plasmon polaritons across resonator and an additional contribution from complex reflection coefficient at antenna termination. This makes theory self-contained with no need fitting parameters. The very resonances are then explained by simple Fabry-Perot model....
The composition of anaerobically digested sludge is inherently complex, enriched with structurally complex organic compounds and nitrogenous constituents, which are refractory to biodegradation. These characteristics limit the subsequent rational utilization resources from sludge. White-rot fungi (WRF) have garnered significant research interest due their exceptional capacity degrade recalcitrant pollutants. However, exploration WRF in context treatment remains an under-investigated area...
We demonstrate current self-complianced and self-rectifying bipolar resistive switching in an Ag-electroded Na-doped ZnO nanowire device. The is controlled by the formation rupture of Ag nanoisland chain on surface along nanowire. Na-doping plays important roles both self-compliance properties.
Self-rectifying resistive switching is demonstrated in Ga-doped ZnO single nanowire device. The current not only self-rectifying but also self-compliance for Sb-doped devices which multilevel has been achieved by using different SET voltages.
Liquid catalyzed fuel cell (LCFC) is a kind of redox flow directly converting carbohydrates to electricity. To improve its efficiency, ferric chloride (FeCl3) was introduced as main catalyst. As mono catalyst, phosphomolybdic acid (PMo12) much better than phosphotungstic (PW12) and FeCl3 intermediate between them. Compared with PMo12 at the optimal dose 0.30 mol/L, combination (1.00 mol/L) PW12 (0.06 achieved similar power output from glucose (2.59 mW/cm2) or starch (1.57 mW/cm2), even...
