With the depletion of fossil fuels and increasing demand energy for economic development, it is urgent to develop renewable technologies sustain growth. Electrospinning a versatile efficient fabrication method one‐dimensional (1D) nanostructured fibers metals, metal oxides, hydrocarbons, composites, so forth. The resulting nanofibers (NFs) with controllable diameters ranging from nanometer micrometer scale possess unique properties such as high surface‐area‐to‐volume aspect ratio, low...
Hydrazine is carcinogenic and highly toxic so that it can lead to serious environmental contamination health risks although has been extensively used as an effective propellant important reactive base in industry. Thus, the development of two-emission NIR fluorescent probes for rapid detection hydrazine with high selectivity sensitivity significance great challenge both biological sciences. Here, we report a colorimetric probe specific based on hydrazinolysis reaction under physiological...
We demonstrate a novel approach to rapidly fabricate conductive silver electrodes on transparent flexible substrates with high-bonding strength by laser-direct writing. A new type of ink composed nitrate, sodium citrate, and polyvinylpyrrolidone (PVP) was prepared in this work. The role PVP elucidated for improving the quality electrodes. Silver nanoparticles sintered microstructures were simultaneously synthesized patterned substrate using focused 405 nm continuous wave laser. writing...
A novel compact microstrip ultra-wideband (UWB) bandpass filter (BPF) is proposed using a multiple-mode resonator (MMR), aiming at transmitting signals in the whole UWB passband. The resonant frequencies of this MMR design are properly adjusted equally within Then, two aperture-backed interdigital coupled-lines sides introduced for an effective enhancement capacitive coupling factor. Transmission zeros can be created lower and upper passband edges to improve selectivity greatly. Finally,...
A small ultrawideband (UWB) slot antenna is proposed using a stepped impedance resonator feeding line, aiming at improving band-edge selectivity. The mainly comprises line with low-pass characteristics the top of dielectric substrate and two slots bottom. used to improve upper selectivity, narrow near improves lower frequency selection range, selective characteristic, reflected zeros are analyzed studied. measured results show that covers range UWB systems from 3.1 11 GHz (114%) reflection...
Rogue access point attack is one of the most important security threats for wireless local networks and has attracted great attention from both academia industry. Utilizing received signal strength information an effective solution to detect rogue points. However, formed by multi-dimensional vectors that are collected multiple sniffers, these inevitably lacking in some dimensions due limited transmission range link instability. This will result high false alarm rate detection. To solve this...
A strategy for growth of porous Ni2GeO4 nanosheets on conductive nickel (Ni) foam with robust adhesion as a high-performance electrode Li-ion batteries is proposed and realized, through facile two-step method. It involves the low temperature hydro-thermal synthesis bimetallic (Ni, Ge) hydroxide precursor Ni substrates subsequent thermal transformation to nanosheets. The as-prepared possess many interparticle mesopores size range from 5 15 nm. hierarchical structure supported by promises fast...
Abstract A compact reconfigurable filtering ultra-wideband (UWB) antenna with switchable band-notched functions is proposed. The basic structure of the proposed design a slot good band-edge selectivity using stepped impedance resonator feeding line. reconfigurability achieved by two microstrip lines paralleling to line and PIN diodes. bias circuit are relatively simple not connected radiation structure, so they have little negative influence on characteristics antenna. Total four states...
A novel compact microstrip ultra-wideband (UWB) bandpass filter with three sharply notched bands and good selectivity is presented in this letter. Triple-notched filtering effects are achieved by adding open-circuited stubs introducing asymmetric dual-line coupling structure to the feed lines, providing a high degree of adjusting freedom not increasing size. The frequencies upper stopband transmission zero can be independently controlled structural parameters lines. Finally, UWB...
