“…Relying on the technical application of artificial intelligence and wireless communication, smart terminals based on wearable and flexible electronics ballooned in recent years. − However, the extensive usage of wireless communication technology in these devices causes information leakage and serious EM radiation pollution that threaten human health. , Therefore, the development of electromagnetic interference (EMI) shielding materials had become a research hotspot. By reflecting, absorbing, or blocking EM waves with EMI shielding materials, the EM energy and field strength were attenuated below safe values even though EM pulses penetrate the shield.…”

Traditional electromagnetic interference (EMI) shielding films generally have constant shielding efficiencies that cannot respond to the real-time changing shielding requirements of smart wearable electronics. Here, we report a stress-gated EMI shielding fabric with a high elastic strain of 470% that exhibits variable shielding performance by stretching the fabric to different deformations. The fabric is fabricated through electroless plating Cu nanoparticles on the electrospun polyurethane nanofiber films, which can change from conducting to insulating when the stretch deformation reaches 50% and then back to conducting as the stress is released. The deformation causes repeated separation and contact of Cu nanoparticles on the surfaces of polyurethane nanofibers, resulting in a reversible transition between conducting and insulating. The fabric with tensile stress-gated conductivity can capture and weaken electromagnetic waves through absorption, reflection, and scattering, which shows real-time changing EMI shielding efficiencies from 0 to 52.31 dB. More importantly, the developed method of electroless plating for the deposition of continuous metal nanoparticles on elastic polyurethane nanofibers is new and scalable, which shows broad application prospects in smart EMI shielding fields.

Density functional theory based calculations were carried out to study electronic properties of transition metal elements doped into silicon carbide monolayers. The slab model SiC after doping with several 3d and 4d transition metals were analyzed to investigate the structural, electronic properties, and catalytic activity of the materials. The electronic properties of the materials after doping and adsorption were analyzed in detail in terms of density of states and band diagrams to get insights into the mechanism involved. The energy profiling was carried out by placing the mono-iodide at different possible sites on the slabs to find the favorable adsorption sites. The thorough study suggested that Zr, Nb, Mo, Cr doped SiC slabs exhibited improved catalytic activity in comparison to Pt doped SiC based CE.

One-dimensional (1D) zirconium dioxide nanofibers (ZrO 2 NFs), as an important inorganic material, have attracted significant attention because of their unique structural characteristics, outstanding chemical/thermal stability, and excellent optical/electronic properties. The biotemplate method, phase inversion method, centrifugal spinning, and electrospinning are facile and highly versatile approaches for the synthesis of ZrO 2 NFs, which have great potential in many emerging applications, such as thermal insulation, air filtration, water purification, catalyst supports, dye-sensitized solar batteries, and lithium-ion batteries. In this review, strategies for synthesizing ZrO 2 NFs with various structures, such as porous, hollow, layered, and even 3D selfassembled structures, are described and analyzed in detail. Recent revolutionary progress in mitigating the brittle nature of ceramics and constructing flexible ZrO 2 NFs, as well as their deformation mechanisms, is also discussed. Then, achievements concerning the application fields of ZrO 2 NFs in thermal insulation, environmental remediation, catalysis, and batteries are presented. Finally, we provide a comprehensive summary of the critical challenges and future perspectives on ZrO 2 NFs. This review is envisioned to guide future research on novel ZrO 2 NFs for emerging applications.
