Chinese calligraphic handwriting practice promotes positive affect in adolescents: Converging evidence from correlational and experimental designs.

Chinese calligraphic handwriting (CCH) practice has proven to be beneficial to several aspects of psychological health and has been considered a complementary therapy for mental disorders. However, less is known about whether CCH practice benefits an individual's positive affect, a core component of affective well-being. Therefore, we examined this question in Chinese adolescents by combining correlational and experimental methods.

A hybrid boronate affinity probe for the selective detection of cis-diol containing compounds in tea beverages.

UiO-66-NH nanocomposite was post-modified with 4-mercaptophenylboronic acid (MPBA) by the method of in situ hybridization reaction. The hybrid boronate affinity material UiO-NH @P (TEPIC-co-MPBA) was characterized by scanning electron microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. The material was applied as fluorescent probe for the detection of cis-diol containing compounds based on the boronate affinity mechanism, and exhibited high specific selectively.

True Grit in Learning Math: The Math Anxiety-Achievement Link Is Mediated by Math-Specific Grit.

In this study, we tested a possible mechanism of the association between math anxiety and math achievement: the mediating role of math-specific grit (i.e., sustaining effort in the face of adversity when learning math).
