Based on the basic idea of expanding interlayer spacing MXene, utilizing effect gallic acid-modified cellulose nanofibers for rapid moisture separation, flexible sensing and driving composite film with a perfect balance among humidity signal response mechanical properties was prepared. Inspired by stacking autumn fallen leaves, nanofibers-based films were formed self-assembly under vacuum filtration blending MXene. The enhanced (tensile strength 131.1 MPa, puncture load 0.88 N, tearing 165.55 N/mm, elongation at break 16.14 %), (the stable induced voltage 63.7 mV response/recovery time 3.2/5.1 s), (154.7° bending angle) observed. synergistic hydrogen bonds, "pinning effect" arising from side chains, hierarchical layered microstructure contributed to performance. This work exemplifies application green natural product preparing intelligent sensing, wearable devices, biomimetic robots.

A simple wet chemical solution method with an inexpensive photochemical synthesis process was performed to fabricate high-quality vertically aligned palladium nanoparticle (Pd NP)-decorated two-dimensional (2-D) zinc oxide (ZnO) nanosheets (NSs) on a seed layer/glass substrate at room temperature. The ultraviolet (UV) photodetectors (PDs) and without decorated Pd NPs in this article were named PdZO@-1 PdZO@-0 NSs, respectively. Field-emission scanning electron microscopy, X-ray diffraction, high-resolution transmission microscopy measurement results showed that the 2-D nanostructures perpendicularly grew substrate, interwoven one another, oriented preferentially along (002) plane good polycrystalline crystallinity. morphological images revealed average length thickness of NSs 2.62 30.2 nm, whereas 2.69 30.5 optical characteristics compositions UV PDs determined by photoluminescence (PL), UV–visible absorbance/transmittance, photoelectron spectroscopy. Energy-dispersive NS samples contained approximately 1.12 at. % element.

Electrochemical humidity (ECH) sensors that integrate power generation and sensing have attracted great research attention in recent years. However, the design of high-performance ECH faces many challenges. Namely, working mechanism is still controversial, related self-powered applications not been well implemented. To overcome these limitations, this study constructs an sensor with high power-generation humidity-sensing performance using KCl/carbon black/halloysite nanotubes (KCl/CB/HNTs) as a electrolyte. The proposed has wide response 10.9%-91.5% relative (RH), single can output 1.46 V maximum 133.2 μW at 91.5% RH. Particularly, unprecedented mixed chemical reactions positive electrode, including hydrogen evolution reaction oxygen reduction reaction, are analyzed multiple characterization testing techniques. analysis results provide solid experimental evidence for current controversial sensors. Due to advantage high-power generation, be used detection. This provides valuable reference improving clarifying their mechanism, which could beneficial guiding future development

Amorphous noble metals often display excellent sensitization due to their unsaturated atomic coordination and abundant active sites on the surface. In this work, amorphous palladium-ruthenium bimetallic nanoparticles were successfully prepared by lithium doping incorporated into MOF-303 using a confinement strategy. Compared with crystalline c-PdRuOx@MOF-303, low-humidity sensor constructed a-PdRuOx@MOF-303 exhibits higher response values (3600 Hz 3.39% RH), shorter response/recovery time (9/7 s), hysteresis (0.16% RH) stability. Meanwhile, has been further explored achieve continuous monitoring of human breathing, cough, finger humidity, providing broad application prospects for materials in wearable medical devices noncontact human-machine interactions. Additionally, sensitive mechanism was GCMC methods. The simulation results demonstrate that introducing a-PdRuOx pores leads significant enhancement adsorption properties. This improvement is not only tothe increase provided but also substantial rise energy hydrophilic pocket MOF-303. increases from -25.70 -31.56 kJ/mol, highlighting work synergy enables activation more water molecules, effectively enhancing overall capacity performance
