Metal halide perovskites have garnered widespread attention for research and applications, thanks to their high adaptability in elemental composition and optoelectronic properties. The mixed Sn-Pb perovskite FASnPbI (FA is formamidinium) features a narrow bandgap of 1.25 eV, appropriate for building tandem solar cells, but faces challenges in fabricating uniform, compact films having protected surfaces and scalable dimensions.

Identifying causality behind complex systems plays a significant role in different domains, such as decision-making, policy implementations, and management recommendations. However, existing causality studies on temporal event sequence data mainly focus on individual causal discovery, which is incapable of capturing combined causality. To address the gap in combined causality discovery on temporal event sequence data, eliminating and recruiting principles are defined to balance the effectiveness and controllability of cause combinations.

This study investigated the stability of chlorophylls within chlorophyll-protein complexes derived from Auxenochlorella pyrenoidosa and developed a novel surfactant-assisted enzymatic modification strategy to enhance chlorophyll stability. Enzymatic hydrolysis with papain in the presence of Tween 80 increased chlorophyll retention to 88.

Atorvastatin (ATO) is a lipophilic and tissue-selective inhibitor of HMG-CoA reductase whose anticancer effects have been validated in various cells, but its effect on the radiation sensitivity of hepatocellular carcinoma cells remains unclear. Therefore, Therefore, this study explored the radiosensitivity of ATO and its possible mechanism by pretreating HepG2 with ATO and collecting HepG2 cells after irradiation.

The abnormal proliferation and hypertrophy of adipocytes mediate the expansion of adipose tissue, which is the main cause of obesity-related diseases. Inhibition of cell proliferation during the mitotic clonal expansion (MCE) period of adipogenesis may be a promising strategy for preventing and treating obesity.

Stable luminescent diradicals, characterized by the presence of two unpaired electrons, exhibit unique photophysical properties that are sensitive to external stimuli such as temperature, magnetic fields, and microwaves. This sensitivity allows the manipulation of their spin states and luminescence, setting them apart from traditional closed-shell luminescent molecules and luminescent monoradicals. As a result, luminescent diradicals are emerging as promising candidates for a variety of applications.

One reason for this difficulty may lie in an over-reliance on the assumptions inherent in existing theories of facial expression - specifically that (1) there is a putative set of facial expressions that signal an internal state of emotion, (2) patterns of facial movement have been empirically linked to the prototypical emotions in this set, and (3) static, non-social, posed images from convenience samples are adequate to validate the first two assumptions. These assumptions have guided the creation of datasets, which are then used to train unrepresentative computational models of facial expression.

In previous research, we identified the Compound Zndm19 as an NDM-1 inhibitor and reported Zndm19 derivatives, which exhibited moderate antibacterial activity when combined with meropenem (MEM). This moderate activity may have been due to the inability of Zndm19 to efficiently penetrate the bacterial outer membrane or its susceptibility to hydrolysis, which prevented it from exerting strong enzyme inhibition in synergy with bacterial cells.

Metal-organic framework (MOF) materials have been considered one of the most promising catalysts, but their application is limited by complicated preparation processes, especially during the synthesis of organic ligands. In this work, a new three-dimensional Cu-MOF () with high porosity was constructed based on the naphthalene diimide (NDI) ligand.

Phenotypic responses are often quantified at a single time point during seedling development at different temperatures. However, to capture growth dynamics, several time points need to be assessed, and ideally continuous measurements are taken.
