Characterization of co-fired sodium-ion conductive Na2Ni2TeO6 and Na2Zn2TeO6 with honeycomb layer structure
We investigated the reactivity of P2-type honeycomb layered oxides Na2Ni2TeO6 (NNTO) and Na2Zn2TeO6 (NZTO) co-fired at the temperature from 500 °C to 800 °C. From X-ray diffraction measurements, it was found that the reaction between NNTO and NZTO is unremarkable at the temperature below 700 °C. However, when annealed at 800 °C, they formed the solid-solution phase without any secondary phases. The NNTO and NZTO composite pellets co-fired at 800 °C showed sodium-ion conductivity well above 10−4 S cm−1 at room temperature, indicating that the solid-solution phase of NNTO and NZTO has good ionic conductivity. A maximum room temperature conductivity of 7.4 × 10−4 S cm−1 was confirmed at the mixing ratio NNTO: NZTO = 0.5 : 1.5. These results can be applied to the fabrication of all-solid-state batteries using NNTO as the cathode active material and NZTO as the solid electrolyte via a simple co-sintering process.journal articl

DSND: Delay-Sensitive Network Design Scheme for Multi-Service Slice Networks
This letter proposes a delay-sensitive network design scheme, DSND, for multi-service slice networks. DSND contributes to a virtual processing system where users can share the same application space regardless of distance-related delays. DSND introduces the service slice and service virtual time concepts. A service slice is a virtual network comprising user and server nodes. A service virtual time is a time for eliminating the difference in delay caused by distance, and the user’s events are reordered in occurrence order. The difference between the current time and the service virtual time is the end-to-end delay shared by all users within the same service slice. We formulate DSND as an integer linear programming problem and compare the delays between DSND to a benchmark scheme where each user selects the closest server. Numerical results indicate that DSND can reduce the delay by 4–38 ercent compared to the benchmark scheme.Date of Publication: 04 April 2024journal articl
