Nonuniform Doppler extraction-enhanced multichannel extensive cancellation algorithm for passive radar using Iridium satellite signals.

Passive radar (PR) relies on receiving signals reflected from targets by other existing noncooperative radiation sources, which are broadly divided into ground- and space-based categories, to achieve target detection and tracking. In the context of space-based PR, this paper proposes a PR using the Iridium satellite signal, which is a low-orbit satellite communication signal with global coverage. With an improved detection range and accredited ambiguity function, a PR using the Iridium satellite signal can address the issues of limited terrestrial coverage for ground-based PR and insufficient receiving power for medium- to high-orbit space-based PR.

Dynamic Bearing-Angle for Vision-Based UAV Target Motion Analysis.

The Bearing-Angle algorithm effectively improves the observability of vision-based motion estimation for moving targets by combining the dimensional information of target detection frames. However, the robustness of this algorithm will be significantly reduced when the observation error increases due to sudden changes in the target motion state. To address this shortcoming, this paper proposes a visual target motion estimation algorithm called the Dynamic Bearing-Angle, which aims to improve the accuracy and robustness of target motion analysis in dynamic scenarios such as unmanned aerial vehicle (UAV).

CRISPR-based one-pot detection: A game-changer in nucleic acid analysis.

The CRISPR/Cas system, originally developed as a gene-editing tool, has rapidly emerged as a powerful platform for nucleic acid detection due to its remarkable specificity, programmability, and robust trans-cleavage activity. While conventional CRISPR-based assays typically require separate amplification and detection steps, introducing complexity, manual intervention, and contamination risks. Recent innovations have led to the development of one-pot detection strategies that integrate target amplification with Cas-mediated signal generation within a single reaction vessel.

Synergy Between Weak Solvent and Solid Electrolyte Interphase Enables High-Rate and Temperature-Resilient Potassium Ion Batteries.

The rate and wide-temperature performance of graphite-based potassium-ion batteries (PIBs) are limited by slow reaction kinetics at the interphases and the solid electrolyte interphase (SEI) stability. Herein, we strategically designed weak solvating electrolytes (WSEs) to construct an efficient solvated K desolvation with KSO-rich SEI and achieve fast reaction kinetics at the electrode interface through the synergy between the SEI and the WSE. As a result of the beneficial fast reaction kinetics and stability of the electrode interface, the graphite anode shows high levels of rate performance and cycling stability, with a capacity of 249.

Synergistic Electrode and Electrolyte Polarities Lead to Outstanding Organic Potassium-based Batteries.

Organic materials are promising as battery electrodes due to their flexible design, low cost, and sustainability. Although high electrolyte concentrations are known to suppress organic cathode dissolution, the organic cathode solubility depends on the interplay between the electrode and electrolyte polarities, which remains unexplored.

Multiple Electron Transfers Enable High-Capacity Cathode Through Stable Anionic Redox.

Single-electron transfer, low alkali metal contents, and large-molecular masses limit the capacity of cathodes. This study uses a cost-effective and light-molecular-mass orthosilicate material, KFeSiO, with a high initial potassium content, as a cathode for potassium-ion batteries to enable the transfer of more than one electron. Despite the limited valence change of Fe ions during cycling, KFeSiO can undergo multiple electron transfers via successive oxygen anionic redox reactions to generate a high reversible capacity.

Permeable void-free interface for all-solid-state alkali-ion polymer batteries.

All-solid-state batteries suffer from a loss of contact between the electrode and electrolyte particles, leading to poor cyclability. Here, a void-free ion-permeable interface between the solid-state polymer electrolyte and electrode is constructed in situ during cycling using charge/discharge voltage as the stimulus. During the charge-discharge, the permeation phase fills the voids at the interface and penetrates the electrode, forming strong bonds with the cathode and effectively mitigating the contact problem.

The GPE contact layer facilitates stable electrode-electrolyte interphase formation, and the GPE transport layer maintains good ionic transport, which enabled GPE to exhibit a wide electrochemical window and excellent electrochemical performance.

Restructuring Electrolyte Solvation by a Partially and Weakly Solvating Cosolvent toward High-Performance Potassium-Ion Batteries.

Ether-based electrolytes are among the most important electrolytes for potassium-ion batteries (PIBs) due to their low polarization voltage and notable compatibility with potassium metal. However, their development is hindered by the strong binding between K and ether solvents, leading to [K-solvent] cointercalation on graphite anodes. Herein, we propose a partially and weakly solvating electrolyte (PWSE) wherein the local solvation environment of the conventional 1,2-dimethoxyethane (DME)-based electrolyte is efficiently reconfigured by a partially and weakly solvating diethoxy methane (DEM) cosolvent.
