In the pressure‐induced emission enhancement paradigms, harvesting enhanced emission on the basis of original color is still largely hampered due to the recovery or decrement of emission intensity upon decompression. Here, a pressure‐treated strategy is reported to achieve the remarkable green emission enhancement of organic–inorganic metal halide (OIMH) [PP14]2[MnBr4] (N‐butyl‐N‐methylpiperidinium [PP14]+) at ambient conditions. After a cycle of 1 atm to 15.2 GPa, the [PP14]2[MnBr4] shows a 1.67‐fold enhancement in the photoluminescence quantum yield from 54.5% to 90.8%, and green emission monochromaticity is unexpectedly retained. The restriction of motion freedom of [MnBr4]2− by increased Br···H interactions is highly responsible for the intense emission. Furthermore, [PP14]2[MnBr4] exhibits significant piezochromism that shifts from green to red, and an ultrabroad tunability of 185 nm is observed below 12.5 GPa. The enhancement of the crystal field splitting energy and the reduction of the relaxation from the low‐energy excited state 4T1 to the ground state 6A1 that is caused by the shrinkage of MnBr bond result in the red shift of emission. This work sheds light on the effects of pressure treatment in boosting emission enhancement and facilitates the design of new OIMHs with the desired emission properties.

Two-dimensional (2D) nanomaterials have fascinating structural, electrical, and optical properties, especially strong excitonic effects due to decreased dielectric screening. However, constructing 2D ultrathin nanomaterials, with the exception of layered materials, remains a challenge. Herein, we successfully realize oriented attachment on guiding one-dimensional chalcopyrite CuInS 2 nanocrystal (NC) formation and 2D assembly into lamellar nanosheets by applying pressure-driven sintering of zero-dimensional CuInS 2 nanoparticles (NPs). We discuss the atomic-level mechanism of such phenomena and illustrate a pressure-driven processing diagram that reveals the sintering process of NPs coordinated by pressure and structural transformation. Optical measurements exhibit that the band gap has a narrowing by 0.21 eV compared with the initial 2.03 eV upon decompression to ambient conditions. Our findings represent a significant step forward in gaining an in-depth understanding of the pressuredriven morphology engineering of nanomaterials and provide a promising strategy to prepare 2D NCs, thereby greatly increasing the choice of materials for various applications.

The senior market signifies an enormous, rapidly expanding segment, and this research aimed to investigate this segment by proposing a theoretical model incorporating the antecedents of consumer flow experience, flow theory, and technology acceptance model (TAM) devised for determining social media purchase intention. This study focuses on the senior citizens engaged in shopping using social media located in Pakistan. A total of 300 senior citizens were selected. An online survey was conducted with the help of a marketing research agency located in Pakistan. The data were analyzed using the partial least squares (PLS) method. According to the results, the antecedents, such as feedback, enjoyment, and time distortion were found to be in a positive relationship with flow experience, however, the concentration did not have a significant effect on the flow. Furthermore, the flow was found to be in a significant relationship with social media purchase intention and TAM. Finally, TAM was also found to be in a positive significant relationship with social media purchase intention. This research contributes to the constantly expanding volume of the utilization of social media by the senior market segment population for buying and producing the highly valuable knowledge for manufacturers, wholesalers, vendors, and a huge number of senior customers.

Bladder cancer (BC) is a prevalent cancer, which arises from the epithelial lining of the urinary bladder. CAMP-response element binding protein (CREB1) acts as a transcription factor, which regulates cell transcription through phosphorylation and dephosphorylation. The purpose of this study was to explore how miR-122 worked in BC on cell proliferation and invasion. RT-qPCR was applied to evaluate the mRNA levels of CREB1 and miR-122 in BC. CCK-8 and Transwell assays were employed to determine the migratory and invasive abilities. Dual luciferase reporter assay was applied to verify miR-122 targeting CREB1 in BC. CREB1 was upregulated in bladder tissues and T24, UM-UC-3 and J82 cells, while miR-122 upregulated and had negative correlation with CREB1. Moreover, knockdown of CREB1 inhibited cell proliferative and invasive capacities. In addition, CREB1 was directly targeted by miR-122 in BC and regulated its expression. We discovered that CREB1 could reverse partially the function of miR-122 on cell proliferation and invasion. CREB1 was mediated by miR-122, and regulated cell proliferation and invasiveness. The newly identified miR-122/CREB1 axis provides novel insight into the pathogenesis of BC.
