Significantly, this work highlights innovative applications of MXene-Ti₃C₂T_x neuromorphic devices in cutting-edge computing paradigms, particularly near-sensor computing and in-sensor computing. Finally, this review carefully compiles a table that integrates almost all research results involving MXene-Ti₃C₂T_x neuromorphic devices and discusses the challenges, development prospects, and feasibility of MXene-Ti₃C₂T_x-based neuromorphic devices in practical applications, aiming to lay a solid theoretical foundation and provide technical support for further exploration and application of MXene-Ti₃C₂T_x in the field of neuromorphic devices.

Currently, perovskite solar cells have achieved commendable progresses in power conversion efficiency (PCE) and operational stability. However, some conventional laboratory-scale fabrication methods become challenging when scaling up material syntheses or device production. Particularly, the prolonged high-temperature annealing process for the crystallization of perovskites requires a substantial amount of energy consumption and impact the modules’ throughput. Here, we report a modified near-infrared annealing (NIRA) process, which involves the excess PbI₂ engineered crystallization, efficiently reduces the preparation time for perovskite active layer to within 20 s compared to dozens of min in conventional hot plate annealing (HPA) process. The study showed that the incorporated PbI₂ promoted the consistent nucleation of the perovskite film, leading to the subsequent rapid and homogeneous crystallization at the NIRA stage. Thus, highly crystalized perovskite film was realized with even better crystallization performance than conventional HPA-based film. Ultimately, efficient perovskite solar modules of 36 and 100 cm² were readily fabricated with the optimal PCEs of 22.03% and 20.18%, respectively. This study demonstrates, for the first time, the successful achievement of homogeneous and high-quality crystallization in large-area perovskite films through rapid NIRA processing. This approach not only significantly reduces energy consumption during production, but also substantially shortens the manufacturing cycle, paving a new path toward the commercial-scale application of perovskite solar modules.

Conductive hydrogels have garnered widespread attention as a versatile class of flexible electronics. Despite considerable advancements, current methodologies struggle to reconcile the fundamental trade-off between high conductivity and effective absorption-dominated electromagnetic interference (EMI) shielding, as dictated by classical impedance matching theory. This study addresses these limitations by introducing a novel synthesis of aramid nanofiber/MXene-reinforced polyelectrolyte hydrogels. Leveraging the unique properties of polyelectrolytes, this innovative approach enhances ionic conductivity and exploits the hydration effect of hydrophilic polar groups to induce the formation of intermediate water. This critical innovation facilitates polarization relaxation and rearrangement in response to electromagnetic fields, thereby significantly enhancing the EMI shielding effectiveness of hydrogels. The electromagnetic wave attenuation capacity of these hydrogels was thoroughly evaluated across both X-band and terahertz band frequencies, with further investigation into the impact of varying water content states—hydrated, dried, and frozen—on their electromagnetic properties. Moreover, the hydrogels exhibited promising capabilities beyond mere EMI shielding; they also served effectively as strain sensors for monitoring human motions, indicating their potential applicability in wearable electronics. This work provides a new approach to designing multifunctional hydrogels, advancing the integration of flexible, multifunctional materials in modern electronics, with potential applications in both EMI shielding and wearable technology.

Despite antibiotic treatment, pulmonary lesions are a serious concern in children with severe Mycoplasma pneumoniae pneumonia (MPP). Combination therapy with antibiotics and glucocorticoids is effective. However, the optimal dose of glucocorticoids remains unclear. In a randomized controlled trial, researchers compared low- versus high-dose of methylprednisolone and find the lower-dose being equally effective with fewer adverse reactions. These results strongly recommend the use of low-dose corticosteroid in pediatric severe MPP for efficacy and favourable safety profile.
