Rational construction of a profitable microstructure in carbon-based electromagnetic composites is becoming promising strategy to reinforce their microwave absorption performance. Herein, the design innovatively coupled with metal–organic frameworks (MOFs)-derived method produce hollow Co/C microspheres (Co/C-HS). The resultant combine advantages microstructures and good chemical homogeneity. It found that pyrolysis temperature plays an important role determining properties these...
Carbides/carbon composites are becoming a new kind of microwave absorption (MA) materials with great potential in chemical stability and light weight, as well enhanced performance. Herein, we design series Mo2C/C through simple pyrolysis Mo-substituted ZIF-8 (Mo/ZIF-8). It is found that the transformation zeolitic imidazolate frameworks into carbon polyhedrons accompanied by situ formation ultrasmall Mo2C nanoparticles (Mo2C NPs) less than 5.0 nm. The molar ratio 2-methylimidazole to...
Three-dimensional flower-like Ni microspheres with enhanced microwave absorption performance can be easily synthesized through a simple precursor-directed method.
Abstract Developing facile routes for fabricating highly efficient oxygen evolution reaction (OER) electrocatalysts is in great demand but remains a challenge. Herein, novel molten salt decomposition method to prepare 3D metal nitrate hydroxide (MNH, M = Ni, Co, and Cu) nanoarrays homogenously grown on different conductive substrates, especially nickel foam (NF) OER applications, reported. Compared with the as‐prepared CoNH/NF CuNH/NF, NiNH/NF presents superior electrocatalytic activity...
Fire-detection technology plays a critical role in ensuring public safety and facilitating the development of smart cities. Early fire detection is imperative to mitigate potential hazards minimize associated losses. However, existing vision-based fire-detection methods exhibit limited generalizability fail adequately consider effect object size on accuracy. To address this issue, study decoder-free fully transformer-based (DFFT) detector used achieve early smoke flame detection, improving...
The effects of the materials' energy levels on V oc in binary OSCs are analyzed and level matching strategy materials for high is delivered by machine learning. Experimental results verify reliability this learning approach.
This paper describes a ultra-wideband (UWB) three-stage cascaded high gain amplifier with low group delay variation for phased-array radar system. The shunt inductor at the input not only provides an electrostatic discharge (ESD) path to ground, but also introduces new notch S11, thus extending matching bandwidth. Staggered tuning of load impedance peaks each stage facilitates balance between flat and variation. output further enhances overall while reinforcing bandwidth stability through...
This brief presents a CMOS wideband passive balun low noise amplifier (LNA) based on magnetically coupled resonator (MCR) matching network.
