Exploring generation of Rh(II) metalloradicals by photolysis of Rh(III)-X bond
No full textRhodium(II) metalloradicals featuring an unpaired electron on the d_(z^2 ) orbital display a pronounced role in small molecule activation due to its unique high reactivity. Although catalysis with Rh(II) porphyrins is enormously rare, one of the significant challenges lies in the tedious pathway to generate Rh(II) metalloradicals from Rh-CH3 specials, which are not directly available. Thus, this study outlines our efforts to develop the formation of Rh(II) metalloradical directly from the species having Rh(III)-X bond via photolysis. To achieve this goal, tetramesitylporphyrin (H2TMP) was synthesized and used as a precursor in the synthesis of tetramesitylporphyrinrhodium(III) iodide [(TMP)Rh(III)I]. Then this compound was employed for photolysis using different sources of light, i.e., UV lamp and Hg lamp. Furthermore, the preliminary reaction progress in photochemical experiments was analyzed by UV-vis spectroscopy and NMR

Exploring the role of Fat-Specific Protein 27 (FSP27) in the musculoskeletal system
No full textOur study hypothesized that Fsp27-/- mice, despite having higher oxidative metabolism, would outperform wild-type mice in muscle tests, but results showed impaired endurance and strength in these mice, potentially due to a lack of Fsp27\u27s role in utilizing fat reserves for energy
Mechanochemical Synthesis of Square-Octahedron Metal-Organic Frameworks
No full textMetal-organic frameworks (MOFs) are a class of porous crystalline materials with potential applications in gas storage, catalysis, and other fields. The conventional synthesis of these materials involves toxic solvents and lengthy, energy-intensive heating processes. Because of this, greener alternatives to access MOFs are of special interest. The mechanochemical approach is one such alternative. Mechanochemistry uses minimal amounts of hazardous solvents and achieves high yields in a fraction of the time. However, the scope of mechanochemical synthetic methods is still limited and the mechanism behind the reactions is poorly understood. This work describes mechanochemical synthesis of a subfamily of MOFs with square-octahedron topology (soc-MOFs) for the first time, which is a family of MOFs with distinctive structures. This allows us to expand the synthetic scope of mechanochemistry for MOFs and paves an avenue for future advanced manufacturing
