Enhancing the optical anisotropy of compounds has attracted significant interest in the optical field. Sn-centered crystals, containing stereochemically active lone pairs, are widely regarded as promising birefringent materials. In this study, we successfully synthesized two novel Sn-centered mixed halide birefringent crystals, NaSnFBr and NaSnFI.

Herein, a weak H-bond interface with a suspension electrolyte is developed by adding TiO nanoparticles into the electrolytes. Owing to the strong polarity of Ti-O bonds in TiO, abundant hydroxyl functional groups are formed between the TiO active surface and aqueous environment, which can produce a weak H-bond interface by disrupting the initial H-bond networks between the water molecules, thereby accelerating the mass transfer of Zn and reducing the water activity.

To further investigate the mechanical erosion induced by ultrasound and locally injected phase-shift acoustic droplets in rabbit liver.
Methods: The liver of each rabbit was treated with perfluoromethylcyclopentane (PFMCP) alone, FUS combined with PFMCP (FUS + PFMCP), and FUS combined with PFP (FUS + PFP).
Based on the General Aggression Model (GAM), this study explores the relationship between social media fatigue and online trolling behavior among Chinese college students, focusing on the mediating roles of relative deprivation and hostile attribution bias as key affective and cognitive mechanisms proposed by GAM. Using a cross-sectional survey design, data were collected from 349 college students from Guangdong via an online questionnaire. Key variables, including social media fatigue, relative deprivation, and hostile attribution bias, were measured using validated scales: the SNS Fatigue Questionnaire, the Personal Relative Deprivation Scale, the Word Sentence Association Paradigm for Hostility, and the revised Global Assessment of Internet Trolling.

The present prospective study explored the role of human milk fatty acid composition in this association. Mothers with GDM and normal controls were recruited at 24-28 gestational weeks.
