CsPbI 3 sub-micrometer wires were synthesized by one-pot solution method at near room temperature . The wires are single crystalline with [100] orientation. An strong emission band centered at 470 nm was observed under ultraviolet excitation, and the emission intensity and bandwidth are dependent on the molar ratio of CsI/PbI 2 in the wires. A bright green emission with a lifetime of several tens ns was observed when excited with a soft X-ray, and the spectral response range can be modulated by the molar ratio of CsI/PbI 2 in the wires. The growth mechanism of the wires was discussed, and the influences of the cycling strain and X-ray irrigation time on the X-ray excited optical luminescence of the CsI/PbI 2 wires/PET film were analyzed and discussed.

Developing damping materials that are both optically transparent and mechanically robust, while offering broad frequency damping capacity, is a significant challenge─particularly for devices that require protection without compromising visual clarity. Conventional methods often either fail to maintain transparency or involve complex designs that are difficult to implement. Here, we present an ionogel system that integrates a physically cross-linked elastic copolymer network with a viscous ionic liquid. The competitive interactions between the ionic liquid and the polymer network enable fine-tuning of the mechanical stability and damping capacity. The resulting ionogel is transparent and mechanically robust and exhibits excellent damping over a wide frequency range. Remarkably, a thin layer (0.15 mm) absorbs nearly 60% of the impact force and retains its performance after exposure to extreme conditions. This approach offers a straightforward method for designing advanced damping materials that meet both the aesthetic and functional demands of modern technologies.

In de-oxygen water preparation, it is still a challenge to develop a highly efficient catalyst with less pollution on produced water. Herein, we invented a novel catalytic membrane, in which palladium nanoparticles were well dispersed and exposed sufficiently to the fluid with the help of hydrophilic polymer networks. These catalytic membranes created by dynamic filtration and reversible fixation offer exceptional flexibility in preparation and application. An apparatus for flexible and continuous chemical removal of dissolved oxygen from water was built up and applied to determine the performance of catalytic membranes. When the residence time was 32.3 s, the concentration of DO could be reduced to 10 ppb by a tri-layer catalytic membrane at ambient temperature. This uniquely configured catalytic membrane could be applied in portable and flexible DO requirements, such as experimental setups and pretreatment of instruments.

Integrating functional components into graphene film is crucial for taking full advantage of graphene and manufacturing film-based devices. However, most graphene film-based system acts specialized property with complicated fabricated process, limiting further application. Herein, a highly compatible graphene nanofilm, decorated by electroactive Prussian blue (PB) and photoelectric responsive quantum dots (QDs), has been prepared via a simple and effective oil-water (O/W) self-assembly engineering. Interestingly, this graphene film could be transferred on various substrates for flexible application. As a result, PB and QDs have played a synergic effect with reduced graphene oxide (rGO) matrix, respectively, acquiring both excellent electrochemical sensing behaviors and extremely enhanced photocurrent generation compared with pure QDs film under simulated solar light. Furthermore, impressive biosensing performance has been obtained by enzyme-modified PB-rGO-QDs film. Additionally, proposed film-based wearable textile H 2 O 2 sensor possesses high sensitivity of 53.8 µA mM −1 cm −2 , while developed wearable glucose biosensor exhibits good performance, with a sensitivity of 37.24 µA mM −1 cm −2 . Significantly, wearable devices of PB-rGO-QDs films on textile have established flexible bending lifetime over thousands of cycles, accompanying with stable sensor and photoelectronic properties. Prospectively, PB-rGO-QDs films would provide an efficient strategy of multi-components self-assembly for broadening the application of graphene and developing wearable biosensing/photoelectronic devices.
