A 3D NiCo2O4 nanowire array/carbon cloth (NCONW/CC) was employed as the cathode for Li-air batteries with a non-aqueous electrolyte. After its discharge, novel porous ball-like Li2O2 found to be deposited on tip of nanowires. The special structure and active sites catalysts are also discussed.
In this paper, a polarization and angle-insensitive multi-band adjustable terahertz absorber is proposed numerically investigated, which composed of kind periodic array square graphene ring with Jerusalem cross sheet. The numerical results indicate that the peaks absorptivity reach 99.9%, 98.5% at 2.02THz, 3.44 THz, 7.58 respectively. three resonance frequencies can be dynamically tuned by varying chemical potential. Its physical mechanism analyzed using Coupled Mode Theory (CMT) electric...
Recently, various transition metal dichalcogenides (TMDs)/Ga2O3 heterostructures have emerged as excellent candidates for the development of broadband photodetection, exhibiting merits such optical absorption, efficient interlayer carrier transfer, a relatively simple fabrication process, and potential flexibility. In this work, vertically stacked MoSe2/Ga2O3, WS2/Ga2O3, WSe2/Ga2O3 were experimentally synthesized, all light spanning at least from 200 to 800 nm. The absorption coefficients...
All solid-state thin film batteries of lithium-iodine can be simply fabricated by coating a solid LiI(HPN)2 electrolyte layer on the surface an Li plate and then exposing its to I2 vapor, which shows improved rate performance rechargeability. A compound I2-LiI(HPN)2 serve as new cathode for Li/I2 batteries.
Flexible sensors and photodetectors are among the robust powerful strategies for advanced smart devices. Meanwhile, wide band-gap metal oxides competitive candidates fabricating flexible solar-blind (SBPDs) but still challenging in both fundamental practical fields. Here, we demonstrate amorphous ALD-Ga2O3 (am-ALD-Ga2O3) thin films realized at a moderate temperature toward SBPDs. The bandgap (Eg) of 4.88–5.04 eV depends on changes with thickness am-ALD-Ga2O3 during atomic layer deposition...
Birefringence is at the heart of photonic applications. Layered van der Waals materials inherently support considerable out-of-plane birefringence. However, funnelling light into their small nanoscale area parallel to its optical axis remains challenging. Thus far, lack large in-plane birefringence has been a major roadblock hindering Here, we introduce presence broadband, low-loss, giant in biaxial Ta2NiS5, spanning an ultrawide-band from visible mid-infrared wavelengths 0.3-16 μm. The Δn ≈...
Construction of reasonable nanostructures for electrode materials is regarded as one critical strategy improving capacitance and cycle life supercapacitors (SCs). Here, self-supported, sisal-like CuCo2O4@Ni(OH)2 composites were successfully synthesized on Ni foam using a hydrothermal treatment followed by the electrochemical deposition reaction. Scanning electron microscopy characterization verified that core–shell nanostructure comprising coating CuCo2O4 nanoneedles with Ni(OH)2 nanoflakes....

With difunctional five-member and polyetheramine as precursor, nanocomposites polyhydroxyurethane (PHU) with were synthesized. Transmission electron microscopy (TEM) showed that PHUs microphase-separated; spherical microdomains via POSS-POSS interactions generated size 20~40 nm in diameter. After introduction microdomains, displayed improved thermal mechanical properties. More...
Isotopes are important strategic materials, and irreplaceable central to the fields of national defence, energy security, medical health, scientific research.
