Metal ion-doped organic-inorganic hybrid metal halides have emerged as promising room-temperature phosphorescence (RTP) materials owing to their tunable afterglow properties and significant potential in information security applications. However, optimizing RTP performance and achieving dynamic control over afterglow colors remain challenging in 1D hybrid systems, primarily because of the inefficient energy transfer from RTP-active organic components to external emissive sites. Herein, we report a novel 1D hybrid metal halide benchmark material, [(NBP)CdClHO] (NBP-Cd, NBP = -benzylpiperidone), and a series of Mn-doped derivatives, NBP-Cd:Mn (where represents doping levels from 1% to 50%).

The first step involves integrating the composite learning method into the NN to address the dynamic uncertainties that inevitably arise in manipulators. A composite adaptive updating law of NN weights is formulated, requiring adherence solely to the relaxed interval excitation (IE) conditions.

(LBL), we used iTRAQ (Isotope relative and absolute quantitative labeling) proteomics to screen and identify differentially abundant proteins (DAPs) at five stages (S1-young fruit stage, S2-green fruit stage, S3-early yellowing stage, S4-late yellowing stage, S5-ripening stage). A total of 1799 DAPs and 171 betaine-related DAPs were identified, and phosphatidylethanolamine N-methyltransferase (NMT), choline monooxygenase (CMO), and betaine aldehyde dehydrogenase (BADH) were found to be the key enzymes related to betaine metabolism.

The microscopic mechanism of polysaccharide dissolution was explored through establishing polysaccharides dissolution kinetics model and visualizing the multi-physical fields during ultrasonic process, and an in situ real-time monitoring model was established by the relationship between the chemical value and spectral information collected by near-infrared spectroscopy. The results showed that, under optimal conditions, treatment with ultrasound (28-33 kHz, 250 W, 30 min) not only significantly promoted the dissolution rate of polysaccharides in Lycium barbarum pulp (LBPPs, increased by 43.
