Metauniverse is a future society based on the convergence of the physical and the digital world, which is fully indebted to the sophisticated human-machine interface (HMI) to connect the two worlds. In this study, a metauniverse sport interactive system based on TENG has been developed, realizing interaction with human beings, devices, and the internet in real-time. This metauniverse sport interactive system is consistent with a self-powered anaerobic power meter (APM), a wireless transmission module, personalized data analysis based on the professional Wingate anaerobic power test method, and an augmented reality (AR) application. Self-powered APM is integrated with the axles of the bicycle to monitor human exercises, such as peak power (PP), mean power (MP), and fatigue index (FI). The data is transmitted to the cloud by the wireless transmission module and users can freely explore the metauniverse through the AR application. As a result of machine learning, the professional Wingate anaerobic power test method can not only reflect the anaerobic capacity, but also be used for athlete selection. This work provides a new approach to online competitions, sport training, and athlete selection and provides a new way to build metauniverse. © 2023, The Authors. All rights reserved.

The traditional single three-phase two-level voltage source inverter introduces high-frequency current ripple due to pulse width modulation. It leads to high-frequency vibration and noise in motor control. To solve this problem, carrier phase-shift SVPWM (CPS-SVPWM) algorithm for a dual three-phase PMSM system is proposed in this paper. First, the reasons for the high-frequency torque ripple in the traditional three-phase PMSM system is analyzed. On this basis, a carrier phase shift algorithm is proposed for the dual three-phase PMSM system to reduce the motor torque ripple. Finally, finite element simulation verified the effectiveness of the algorithm. © 2021 IEEE.

Robot-assisted Natural Orifice Translu-minal Endoscopic Surgery (NOTES) represents a paradigm shift in surgical practice, significantly mini-mizing patient morbidity. However, the variability of inner diameter and the inter-luminal crossing within the luminal tracts lead to challenge for effective robotic intervention. Inspired by the motion of the chrysalis during its transformation, we designed an innovative pupal-mode actuator for NOTES robots. Through the manipulation of its internal air chambers, this actuator is capable of replicating wriggle-like movements. Through experimental analysis, we have acquired the constitutive characteristics of this actuator. Subsequently, an innovative gastric endoscopy robot is developed base the actuator and tested in a phantom. The results of the task simulations substantiate that the pupal-mode actuator has the capability to reduce resistance and enhance the safety of the endoscopic intervention.

A new concept of a nonlinear nanoantenna with multiple functions is suggested. We give theoretical research on the temporal dynamics for this asymmetric system which consistis of a pair of graphene-wrapped dielectric nanoparticles with tunable Fermi energies. It is demonstrated that asymmetry can lead to an enlarged stationary multistable regime and enrich the temporal dynamical behaviors compared to the symmetry counterpart. Such a nanoantenna can provide a chance to switch among coexisting nonlinear states under the illumination of a sequence of external pulses, which simultaneously leads to not only the manipulation of the angular scanning sector and scattering pattern of nanoantenna but also the controllable multistate optical switching or coding element. This kind of asymmetric dimer system may represent a possible step toward the development of tunable applications in nonlinear nanophotonics and biophotonics.

LDOS is a fundamental spectral property that plays a central role in various physical phenomena, such as wave-matter interactions and spontaneous emissions. The role of LDOS in acoustics was uncovered only in recent years and the measurement of acoustic LDOS has not yet been achieved. Here, we report on the direct measurement of the LDOS in acoustic systems. The acoustic LDOS is quantified here through the measurement of the volume flow rate and the acoustic pressure with a local excitation-probe configuration. Based on this method, we detect the LDOS in the one-dimensional acoustic Su-Schrieffer-Heeger model and observe the fractional topological charge of the system. Our work unveils the role of the LDOS in acoustic phenomena and paves the way toward characterizing and tailoring the LDOS in acoustic systems, which holds promise for applications in acoustic emission control, energy localization, and wave-matter interaction.

Covalent organic frameworks (COFs) have been widely used in various fields due to their abundant elemental resources, easy structure control, and abundant tunable porous structures. COFs containing electroactive organic groups with reversible redox behavior are potential electrode materials for next-generation high-performance lithium-ion batteries (LIBs). However, the aromatic conjugated structure of the backbone moiety in most reported COFs cannot participate in redox reactions, resulting in low capacity of COFs. At the same time, the synthesis processes of COFs are usually complicated and generally requires high temperature and high pressure. On this basis, an imine bond-rich COF (TAACOF) with reversible Li-ion bonding is developed, which has the advantages of facile preparation and low energy consumption. In particular, the lone pair electrons of the N atom in the imine bond can induce lithium ions to combine with the aromatic conjugated structure, which greatly improves the capacity of the TAACOF electrode. After 800 cycles, the active sites of the TAACOF are fully activated, and after a 14-electron redox reaction, the specific capacity can reach as high as 1035.7 mAh g-1. © 2023, The Authors.

Boosting Sodium-Storage Behaviors of Nasicon-Type Nati2(Po4)3 Anode by Synergistic Modulations in Both Materials and Electrolytes Towards Aqueous Na-Ion Batteries

SSRN

SSRN 2023年

作者： He, Yuting Chen, Huaqing Wang, Yongjia Zhang, Yamin Hou, Linrui Jiang, Ruiyu Yuan, Changzhou School of Materials Science & Engineering University of Jinan Jinan250022 China Key Laboratory for Advanced Technology in Environmental Protection of Jiangsu Province Yancheng Institute of Technology Yancheng224051 China

NASICON-type NaTi2(PO4)3 (NTP) is one of the most competitive anode materials for aqueous sodium-ion batteries (ASIBs), thanks to its unique three-dimensional open framework structure, high ionic conductivity and good chemical stability. However, the low electrical conductivity of NTP and the oxygen reduction induced side reactions seriously affect its practical applications. To well address the above issues, the synergistic regulation strategy in electrode materials and electrolytes is motivatively put forward. The porous single-crystal NTP micro-sized framework coated with conductive carbon nano-layers (denoted as NTP@C) is designed with significantly improved electronic conductivity and structural stability. With further regulations in both the dissolved oxygen content and pH values of aqueous Na2SO4 electrolyte, the enhanced reversible capacities and cyclic stability especially at high rates are achieved by effectively alleviating side reactions. As a result, the fabricated NTP@C anode is optimized with a high-rate capability and remarkable long-duration electrochemical stability in the N2-purged aqueous Na2SO4 electrolyte with pH = 8.0. Furthermore, the assembled NTP@C//Na0.44MnO2 ASIBs exhibit high energy density of ~40.0 Wh kg‒1 along with excellent cycling stability. More significantly, our work provides an insightful guideline for rational construction of other advanced aqueous rechargeable batteries. © 2023, The Authors. All rights reserved.
