Regenerable nanozymes with high catalytic stability and sustainability are promising substitutes for naturally-occurring enzymes but limited by insufficient non-selective activities. Herein, we developed single-atom of RhN
Strong fluorescence and high catalytic activities cannot be achieved simultaneously due to conflicts in free electron utilization, resulting a lack of bioactivity most near-infrared-II (NIR-II) fluorophores. To circumvent this challenge, we developed atomically precise Au22 clusters with strong NIR-II ranging from 950 1300 nm exhibiting potent enzyme-mimetic through atomic engineering create active Cu single-atom sites. The Au21Cu1 show 18-fold higher antioxidant, 90-fold catalase-like,...
A green approach was successfully developed to fabricate flexible sensors by utilizing carbonized waste cotton fabrics in combination with natural rubber latex. Waste were firstly heat treatment the nitrogen atmosphere before they combined latex using three methods, i.e., vacuum bagging, negative pressure adsorption and drop coating. After impregnation rubber, maintained fabric structure showed good conductivity. More importantly, electric resistance of textile composites changed tensile...
In modern electronic warfare, array radar systems apply adaptive beamforming techniques to form nulls in the beams toward jamming angles for multiple cancellation. However, lead distortion, especially within mainlobe, which severely degrades target detection ability. To address degradation, this letter proposes joint distributed radars by two-stage processing. First, linearly constrained minimum variance is performed sidelobe cancellation with mainlobe maintenance each radar. After that,...

Abstract Summary: A new technique, ultrasonically initiated in situ emulsion polymerization, was employed to prepare intercalated polystyrene/Na + ‐MMT nanocomposites. FTIR, XRD, and TEM results confirm that the hydrophobic PS can easily intercalate into galleries of hydrophilic montmorillonite via taking advantages multi‐effects ultrasonic irradiation, such as dispersion, pulverization, activation, initiation. Properly reducing SDS concentration is beneficial widen d ‐spacing between clay...
Subbanding technique has been applied in wideband (WB) digital array radar systems to address the challenge of high-speed signal processing and WB jamming cancellation. This article reveals that well-established subband decomposition by polyphase filtering could still leave decorrelation post subbanding, which would deteriorate cancellation performance. A novel implementation subbanding processor is then proposed isolating down conversion incorporated operation performing it at baseband...
