Near-field communication (NFC) labeling technology has been recently used to endow smartphones with nonline-of-sight sensing functions improve the environment, human health, and quality of life. For applications in detecting food spoilage, development a sensor high enough sensitivity act as switch for an NFC tag remains challenge. In this Letter, we developed nanostructured conductive polymer-based gas ΔR/R0 = 225% toward 5 ppm ammonia NH3 unprecedented sensitivities 46% 17% putrescine...
Regulating dielectric genes of hollow metal-organic frameworks is a milestone project for microwave absorption (MA). However, there still bottleneck in deciphering the contribution various genes, making it hard to expand MA potential from selective encoding gene sequences. Herein, custom-made proton tailoring strategy used build controllable cavity, and meticulously designed thermodynamic regulation promotes rearrangement carbon atoms disorder order, thus enhancing characteristics charge...

Abstract Efficient electromagnetic waves (EMWs) absorbing materials play a vital role in the electronic era. In traditional research on microwave (MA) materials, synergistic modulation of material dispersion and structural EMWs by incorporating multi‐scale effects has frequently been overlooked, resulting an untapped absorption potential. this study, customization method based biomass carbon is determined quantitative analysis. The study carries out thermodynamic skeleton, micro‐nano porous...
Topological insulators have unconventional gapless edge states where disorder-induced back-scattering is suppressed. In photonics, such lead to unidirectional waveguides which are useful for integrated photonic circuitry. Cavity modes, another type of fundamental component in chips, however, not protected by band topology because their lower dimensions. Here we demonstrate that concurrent wavevector space and real-space topology, dubbed as dual-topology, can light-trapping The resultant...
A low-loss hollow core terahertz waveguide based on Kagome photonic crystal structure has been designed and fabricated by 3D printing. The printed characterized using THz time-domain spectroscopy. results demonstrate that the obtained features average power propagation loss of 0.02 cm-1 for 0.2-1.0 (the minimum is about 0.002 at 0.75 THz). More interesting, it could be simply mechanically spliced without any additional alignment, while maintaining excellent performance. printing technique...
MOFs with high tunability are considered ideal candidates as microwave-absorbing materials.
The combination of Ag nanomaterials and special nanostructures can significantly amplify the conversion electromagnetic energy, especially in microwave absorption applications. Herein, a kind multishell Ag/C composite nanoparticle with about 635 nm size prepared by self-assembly method was reported, which nanoparticles were 20–40 size. In process synthesis, Ag-related interfere internal cross-linking degree phenolic polymers, embedded into carbon after acetone etching high-temperature...
Correlating metal-organic framework (MOF) synthesis processes and microwave absorption (MA) enhancement mechanisms is a pioneer project. Nevertheless, the correlation process still relies mainly on empirical doctrine, which hardly corresponds to specific mechanism of effect dielectric properties. Hereby, after strategy modulation protonation engineering solvothermal temperature in route, obtained sheet-like self-assembled nanoflowers were constructed. Porous structures with multiple...

We experimentally demonstrate that electromagnetic waves in the waveguide comprising gyromagnetic photonic crystals (GMPCs) and a metal cladding are robust one-way slow frequency range of chiral edge states GMPC. Measured with phase shift technique microwave regime, group velocity wave could be one order magnitude smaller than speed light index up to 15.6. The much slower is shown by retailoring further. This provides potential way realize slow-light transmission lines or optical systems.

We show that properly designed reflective can be used substitute metallic ground conventional generating diverse...
Numerous previous studies have investigated how different synthesis parameters affect the chemical properties of catalysts and their performances. However, traditional trial error optimization in comprehensive multiparameter spaces that is driven by intuition may cause influencing factors to be artificially ignored. Hence, we introduce machine learning provide insights feature ranking based on data sets. Taking zeolite imidazole framework-derived oxygen reduction as an example, computing...
