Summary: The supramolecular assembly process of hydrophilic Co(III)-tetra(4-sulfonatophenyl)porphyrin with 4,4'-bipyridyl in aqueous buffer media and its interaction with ionic micelles were studied using various spectroscopic methods. The results demonstrated that the metalloporphyrins could be incorporated into micelles, leading to the reduction of Co(III) to Co(II). The rate of Co(III) reduction depended on the concentration and nature of the micelles.

Summary: This study examines the influence of cyber incivility on employees' task performance at a daily level. The results, based on data collected from 112 full-time employees, show that daily cyber incivility has a time-lagged effect on task performance of the following day. This effect is explained by the negative affect induced on the following workday, rather than the sleep quality of the previous night. Additionally, the relationship between cyber incivility and negative affect, as well as the indirect effect on task performance, is weaker among employees with high self-leadership.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
