Four coordination compounds [Zn (CH COO) (H O) ](TT) [Cd(H O) ](ClO ) (TT) , [Cd(H O) ](BF ) (TT) , [Zn(H O) ](BF ) (TT) (1-4) accommodating the crystallization induced emissive triimidazo[1,2-a:1',2'-c:1'',2''-e][1,3,5]triazine (TT) as a guest in their crystal lattice are isolated and fully photophysically and structurally characterized. Their emission properties are compared with those of afterglow TT and interpreted taking into account the heavy atom effect and crystal packing similarities and differences. In the case of 1, due to the closeness of the TT H-aggregates arrangement with that of the phosphor's pure phase, the observed intensification of the phosphorescent emission at the expense of the prompt one is attributed to the extrinsic heavy atom effect of Zn. In 2 and 3, the heavier Cd atom is responsible for a decrease in the lifetimes of the afterglow emission, despite the presence of tightly overlapped H-dimers in the crystal structure. Finally, for 4, isostructural with 3, the Zn atom reveals in RTUP lifetime comparable with that of 1.
Zeolites are crystalline microporous materials constructed by corner-sharing tetrahedra (SiO and AlO), with many industrial applications as ion exchangers, adsorbents and heterogeneous catalysts. However, the presence of micropores impedes the use of zeolites in areas dealing with bulky substrates. Introducing extrinsic mesopores, that is, intercrystal/intracrystal mesopores, in zeolites is a solution to overcome the diffusion barrier.
γ-MnO precoated lead (Pb)-based anodes have shown high initial activity in heavy-metal pollution reduction and production improvement for zinc electrowinning in laboratory. However, the accumulated impurity ions (M) in industrial MnO-precursors restrict its industrial application. Herein, the heterostructure-induced rich oxygen-vacancies for M-MnO and its higher activity (Pb/Co-MnO>Pb/Ni-MnO>Pb/Fe-MnO ≈Pb/Cu-MnO>Pb/MnO) was reported.

- The study investigated stress levels among nurses, identifying three distinct categories: low, moderate, and high perceived stress, with most nurses (66.7%) falling into the moderate category.
- Data were collected from 696 nurses in Shanxi Province, China, through electronic surveys that measured factors like sociodemographics, job stressors, effort-reward imbalance, and organizational support.
- Key findings highlighted that working hours and effort-reward imbalance significantly influenced stress levels, showing that longer hours and higher extrinsic effort correlated with increased perceived stress among nurses.
Hypertrophy Cardiomyopathy (HCM) is the most prevalent hereditary cardiovascular disease - affecting >1:500 individuals. Advanced forms of HCM clinically present with hypercontractility, hypertrophy and fibrosis. Several single-point mutations in b-myosin heavy chain (MYH7) have been associated with HCM and increased contractility at the organ level.

Spin-orbit torque magnetic random access memory (SOT-MRAM) offers high write speeds and low power usage, with Mo potentially improving the performance of CoFeB/MgO MRAM cells.
Despite its weaker spin-orbit coupling, our study shows that amorphous Mo achieves notable SOT efficiencies, specifically a damping-like efficiency of 0.015 and a field-like efficiency of 0.050.
The findings suggest that Mo can effectively serve as both an SOT source and a buffer layer for perpendicular magnetic anisotropy, presenting new opportunities for SOT-MRAM development.
