Thiocyanates and trifluoromethyl sulfides are important compounds and have classically been synthesized via multistep procedures together with the formation of significant amounts of byproducts. Herein, we demonstrate an oxidative nucleophilic strategy for the synthesis of thiocyanates and trifluoromethyl sulfides from thiol starting materials using nucleophilic reagents such as TMSCN and TMSCF...

Detailed information on the structure and composition of gallstoneswas obtainedusing an electron probe microanalyser in conjunction with other methods. Gallstones were studied layer by layer without greatly disturbing the arrangement of the materials present. Elements, including trace elements such as copper, iron, and manganese, were identified and their distributions mapped. The range of the ...

Sodium manganese hexacyanomanganate, NaxMn[Mn(CN)6], is an electrochemically active Prussian blue analogue (PBA) that has been studied experimentally as electrode material in rechargeable sodium-ion batteries. It a reversible specific capacity of 209 mA h g–1, which substantially higher than the theoretical 172 g–1 expected for two reduction events conventional PBAs. suggested high originates f...

Manganese (Mn) is a trace element essential for brain development and functioning of the central nervous system. However, there is a lack of information concerning the neurotoxicity of Mn under realistic doses in early stages of development, though excess of Mn results in a progressive disorder of the nervous system called manganism. In the current study, adult mice were exposed to three doses ...

Two structurally homologous Mn compounds in different oxidation states were studied to investigate the relative influence of oxidation state and ligand environment on Mn K-edge X-ray absorption near-edge structure (XANES) and Mn Kbeta X-ray emission spectroscopy (Kbeta XES). The two manganese compounds are the di-mu-oxo compound [L'2Mn(III)O2Mn(IV)L'2](ClO4)3, where L' is 1,10-phenanthroline (C...

spinel-type of mno2 nanoparticles which successfully synthesized by a hydrothermal process, have a required capacity for lithium uptake from liquid resources. themost lithium adsorption capacity of 6.6 mmol/g of up to now was found to be an important limiting parameter for industrial applications. therefore, increasing uptake capacity of these ion sieves by studding the effect of six effective ...

Metals and metal compounds are part of our environment. Several metals are essential for physiological functions (e.g., zinc or magnesium); while the beneficial effects of others are uncertain (e.g., manganese), some metals are proven to be toxic (e.g., mercury, lead). Additionally there are organic metal compounds; some of them are extremely toxic (e.g., trimethyltin, methylmercury), but there...

Single crystals of Mn 1.3 2Ni 0.85 Cu 0.83 BO 5 with the ludwigite structure were obtained by solution-melt method during spontaneous crystallization. The concentration copper, manganese and nickel ions was determined transmission microscopy. Manganese are included in compounds divalent trivalent states. study temperature field dependences showed that we have several magnetic transitions. first...
