Abstract The presence of electrocatalysis in lithium–sulfur batteries has been proposed but not yet sufficiently verified. In this study, molybdenum phosphide (MoP) nanoparticles are shown to play a definitive electrocatalytic role for the sulfur cathode working under lean electrolyte conditions featuring low electrolyte/active material ratio: overpotentials charging and discharging reactions greatly decreased. As result, electrodes containing MoP show faster kinetics more reversible...
Harmonic estimation is an important topic in power system signal processing. Windowed interpolation fast Fourier transformation (WIFFT) efficient algorithm for harmonic estimation, which can eliminate the errors caused by spectral leakage and picket fence effect. However, fitting polynomial procedure contains both even odd terms, this increases computational burden. This paper proposes a simple symmetrical FFT algorithm, where terms are removed from based on triangular self-convolution...
Electrocardiogram (ECG) acquisition is easily contaminated by interferences, and denoising the most important task in ECG detection. The variational mode decomposition (VMD) algorithm widely used denoising, which can overcome aliasing between intrinsic function (IMF) components that existed traditional empirical (EMD) algorithm, but number <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${K}$...
This paper focuses on the accurate frequency estimation of power signals corrupted by a stationary white noise. The noneven item interpolation FFT based triangular self-convolution window is described. A simple analytical expression for variance noise contribution derived, which shows variances are proportional to energy adopted window. Based proposed method, level measurement channel can be estimated, and optimal parameters (e.g., sampling length) algorithm that minimize thus determined....

Ni-Doped ZIF-8 (Ni-ZIF-8) not only restrains the shuttling of LiPSs by chemical adsorption but also facilitates redox reaction kinetics.
Abstract Metallic lithium (Li) is considered the “Holy Grail” anode material for next‐generation of Li batteries with high energy density owing to extraordinary theoretical specific capacity and lowest negative electrochemical potential. However, inhomogeneous Li‐ion flux, anodes undergo uncontrollable deposition, leading limited power output practical applications. Carbon materials their composites controllable structures properties have received extensive attention guide homogeneous growth...
Portable bioimpedance spectroscopy (BIS) devices are of great value for monitoring the pathological status biological tissues in clinical and home environments. The two traditional techniques measuring complex bioimpedance, bridge method quadrature demodulation method, either time-consuming or often associated with high cost, power consumption, large board space, therefore not ideally suitable designing a portable device BIS measurement. This paper describes novel design based on...
Multisine signal with a low crest factor (CF) can bring high signal-to-noise ratio for fast frequency response function (FRF) estimation. Synthesis of CF multisine the given amplitude spectrum depends on optimum selection initial phases its cosinusoidal components. The solutions investigated be generally divided into two branches: (1) analytical method based direct formula calculation; and (2) numerical iterative computations. works well only an equidistant flat spectrum, while output better...
Abstract Computing‐in‐memory (CIM) architecture inspired by the hierarchy of human brain is proposed to resolve von Neumann bottleneck and boost acceleration artificial intelligence. Whereas remarkable progress has been achieved for CIM, making further improvements in CIM performance becoming increasingly challenging, which mainly caused disparity between rapid evolution synaptic arrays relatively slow building efficient neuronal devices. Specifically, dedicated efforts are required toward...
The Cole function is widely used in bioimpedance spectroscopy (BIS) applications. Fitting the measured BIS data onto model and then extracting parameters (R0, R∞, α τ) a common practice. Accurate extraction of from has great significance for evaluating physiological or pathological status biological tissue. traditional least-squares (LS)-based curve fitting method parameter often sensitive to noise outliers becomes non-robust. This paper proposes an improved based on least absolute deviation...
Abstract Since the rapid development of nanomedicine in oncotherapy, multiple nanomaterials are adopted to regulate immune system cancer individuals. Tumor immunotherapy enhances function patients achieve purpose killing tumor cells by utilizing organism mechanism. As emerging inorganic carbon nanoparticles, dots (CDs) have been found as photosensitizers, vaccines, immunoadjuvants, and so on for treatment due their unique structure property, such effective platforms drug delivery,...
Modern Wi-Fi networks are commonly protected by the security mechanisms, e.g., WPA, WPA2 or WPA3, and thus it is difficult for an attacker (a malicious supplicant) to hijack traffic of other supplicants as a man-in-the-middle (MITM). In traditional Evil Twins attacks, attackers may deploy bogus wireless access point (AP) victim supplicants' (e.g., stealing credentials). this paper, we uncover new MITM attack that can evade mechanisms in spoofing legitimate AP send forged ICMP redirect...
