Article Synopsis
- - Radioactive ruthenium can be accidentally released from nuclear fuel reprocessing plants, but there's limited research on its environmental behavior due to its complicated chemical properties.
- - A study was conducted using X-ray absorption fine-structure analysis to examine different chemical forms of stable ruthenium (like RuO4, RuO2, Ru(NO)(NO3)3, and RuCl3) added to soil, revealing how they react and change over time.
- - Results indicated that some forms (e.g., RuO4 and RuCl3) change quickly when in soil, while others (like RuO2 and Ru(NO)(NO3)3) are stable, highlighting the importance of understanding the chemical forms of ru

Ruthenium chloride (RuCl) is widely utilized for synthesis and catalysis of numerous compounds in academia and industry and is utilized as a key molecule in a variety of compounds with medical applications. Interestingly, RuCl has been demonstrated to modulate human plasmatic coagulation and serves as a constituent of a compounded inorganic antivenom that neutralizes the coagulopathic effects of snake venom in vitro and in vivo. Using thrombelastography, this investigation sought to determine if RuCl inhibition of the fibrinogenolytic effects of venom could be modulated by vehicle composition in human plasma.

Metal phosphides have recently emerged as promising electrocatalysts for hydrogen evolution reaction (HER). Herein, we report the synthesis of ruthenium diphosphide embedded on a dual-doped graphitic carbon by pyrolyzing chitosan beads impregnated with ruthenium chloride and phosphorus pentoxide. The as-synthesized RuP@N-P-C displays a good electrocatalytic activity in acidic, neutral and alkaline media.

Radioactive ruthenium may be accidentally released from spent nuclear fuel reprocessing plants to the surrounding environment. To obtain basic information regarding the effect of radioactive ruthenium on the environment, we investigated changes in the source form of stable ruthenium added to rainwater through X-ray absorption fine structure analysis. Ruthenium tetroxide (RuO4), ruthenium dioxide (RuO2), ruthenium nitrosyl nitrate (Ru(NO)(NO3)3) and ruthenium chloride (RuCl3) were employed as test sources.

In this study, the material obtained from the sonication of the double-walled carbon nanotube and ruthenium chloride was produced as an aerogel. Then, symmetrical supercapacitor devices were made using them, and their electrochemical properties were investigated. XRD and FTIR were used in the structural analysis of the aerogel, STEM in surface images, and elemental analyses in EDX.
