Summary: This study reveals the pressure-induced emission (PIE) mechanism of self-trapping excitons (STEs) in low-dimensional halide perovskites by investigating a 2D layered double perovskite material. The results show that pressure can transform dark-state STEs into bright-state STEs, resulting in a strong broadband Stokes-shifted emission. The theoretical analysis further explains that the suppressed lattice distortion and enhanced electronic dimensionality in the excited-state play crucial roles in stabilizing the bright-state STEs.

Summary: The emergence of metal-organic frameworks (MOFs) has provided a new platform for low-cost and color-saturated blue light-emitting diodes, which are ideal for display and solid-state lighting applications. However, many established MOFs still exhibit weak deep-blue-light emission due to low energy/charge transfer efficiency. This research reports a pressure-treated strategy to greatly enhance the photoluminescence performance of deep-blue light-emitting Y(BTC)(H2O)(6) and provides insights into the structure-property relationship in MOFs, offering a promising strategy for developing deep-blue-emitting MOFs materials.

Summary: The catalytic activity of 2D materials has been studied and their unique structural and electronic properties contribute to their success in conventional heterogeneous catalysis. Piezocatalysis based on heterojunctions has attracted attention because of band-structure engineering and enhanced charge carrier separation. A reduced graphene oxide (rGO)-MoS2 heterostructure is designed to tackle challenges such as finite active sites, catalyst poisoning, and poor conductivity. The heterostructure exhibits a record-high piezocatalytic degradation rate, which is significantly higher than that of MoS2 nanosheets. The mechanism of this behavior opens up new possibilities for developing efficient catalysts for wastewater treatment and other applications.

Summary: This study introduces a flex-activated mechanophore (FA) that releases fluorescent anthracenes through a retro-Diels-Alder mechanochemical reaction under compression or hydrostatic high pressure. The force delivered to the mechanophore can be modulated by varying the crosslinking density of the networks and the applied macroscopic pressures, leading to incremental increases in mechanophore activation, successive release of anthracenes, and quantitative enhancement of fluorescence intensity. The exceptional potential of FA as a sensitive force probe in different bulk states is highlighted.

Summary: The properties of mechanoresponsive materials are influenced by intermolecular interaction, which can be modulated using anisotropic grinding and hydrostatic high-pressure compression. Applying high pressure to DPH results in an increased emission and red-shifted piezochromism due to reduced molecular symmetry and pi-pi interactions. By controlling intermolecular interactions, NLC mechanical response can be achieved, while grinding destroys these interactions leading to a blue-shifted luminescence. The evolution of intermolecular interactions has important implications for developing new fluorescence materials and structural materials.

Summary: High sensitivity and multi-mode optical pressure sensing were achieved for the first time by co-doping Eu2+ and Mn2+ ions in the Lu2Mg2Al2Si2O12 (LMAS) host. The co-doping strategy proposed in this research significantly improves the pressure response range of the phosphors, and the decay degree of the overall integral intensity and the fluorescence intensity ratio (FIR) were first proposed to be used for pressure sensing. Therefore, multi-mode optical pressure sensing can be realized with the use of the LMAS:Eu2+,Mn2+ phosphor.

Summary: In this study, we investigated the optical and structural responses of a one-dimensional metal halide (HMTA)(3)Pb2Br7 under pressure. We found that applying mild pressure (<0.6 GPa) resulted in enhanced broadband emission and prolonged carrier lifetime. Additionally, the band gap narrowed with pressure due to enhanced orbital coupling between the metal and halogen. Our high-pressure studies not only reveal the regulation mechanism of self-trapped exciton (STE) emission in one-dimensional metal halides, but also highlight the potential of pressure treatment as a powerful strategy to tune the emission of white-light materials.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
