Abstract Molybdenum disulfide (MoS 2 ) has been proved to be a potential electromagnetic wave (EMW) absorber. However, the limited EMW attenuation mechanisms and conductivity have always recognized as major challenges impeding their further developments. In this study, new dielectric tuning strategy giving rise high performance by manipulating phase content (with 0, 24, 50, 100 wt% 1T phase) toward MoS is demonstrated. The greatly introduced 2H/1T interfaces facilitate dipole distribution...
Abstract To design and develop efficient microwave absorbents via phase engineering is still less studied. The unique properties caused by constructing heterophase structure hold the potential to strengthen absorbing capability toward radiation. Herein, amorphous/crystalline γ‐Fe 2 O 3 nanosheets (Fe‐H) are carefully fabricated through a controlled annealing process. matched Fermi levels formed on both sides of interface not only provides interfacial polarizations but also facilitates...
Abstract A comprehensive study of 2D magnetic ordering mediated second harmonic generation (SHG) is essential for a thorough understanding symmetry and its potential nonlinear applications. Here, an extraordinarily large FM‐mediated SHG demonstrated in CrPS 4 , which possesses both spatial time‐reversal breaking. The inversion breaking gives rise to i‐type response. In contrast, the antiferromagnetic (AFM) bulk even‐numbered layers do not produce any magnetism‐mediated c‐type SHG....
Utilization of biomass waste and solid industrial waste, one the basic solutions green economy, has become an important topic in both chemical materials science. Individual bio-carbon, magnetic oxides, their composites have been used making microwave absorbers. Here, by utilizing coffee bio-carbon MnFe2O4 particles, efficient absorber realized based on composites. The absorption performance as well magnetization as-synthesized can be tuned adjusting particle size MnFe2O4. minimum reflection...
In this work, by taking commercial P25 hydrophilic titanium dioxide (TiO2) as a photocatalyst, the magnetic field effect (MFE) on photodegradation rate of methyl orange is studied. It found that relatively lower B = 0.28 T can efficiently enhance efficiency TiO2 24%. However, will be suppressed slightly 7% under 0.5 T. Moreover, such MFE photocatalyst dependent settling state reaction solution. Additional experiments degradation other pollutants (methylene blue) and with photocatalysts...
Besides composition, macrostructure of a material is also crucial to its microwave absorption performance. In this work, we demonstrate magneto-alignment effect on the property bio-carbon flakes synthesized from phoenix tree leaves. When magnetic field applied, prepared tended be aligned into desired direction due their diamagnetic feature. Moreover, rotating has better than static one, which significantly boosts efficiency. By adjusting parameters, conditions have been optimized, i.e., 10...
InSe nanosheets and their coupling with P25 have been successfully synthesized <italic>via</italic> a hydrothermal–calcining process, they were for the first time used visible light photocatalytic H<sub>2</sub> production.
Rate and product control are crucial for a chemical process useful in wide range of applications. Traditionally, thermodynamic parameters, such as temperature or pressure, have been used to the reactions. Here, by using fabrication hollow MnxFeyO4 nanostructure model system, we report an experimental tuning both reaction rate high magnetic field. A 12 times magneto-acceleration galvanic replacement (GR) was observed. Moreover, it is first demonstrated that field can unravel accelerate hidden...
