Direct observation of the growth dynamics 2D transition metal dichalcogenides (TMDs) is key importance for understanding and controlling modes tailoring these intriguing materials to desired orientations layer thicknesses. Here, various stages multiple in formation WS2 layers on different substrates through thermolysis a single solid-state (NH4)2WS4 precursor are revealed using situ transmissio...

The synthesis of the tert-butyl-substituted arsanylborane tBuAsHBH2 ? NMe3 is reported. Its reactivity towards main group Lewis acids and transition metal complexes, yielding various coordination products, discussed. Furthermore, it used as starting material in catenation oligomerization processes, leading to cationic catena compounds well neutral oligomers obtained by thermolysis.

A relatively new entrant to the class of high energy materials, viz., 1,3,5-trinitro-5-methyl-hexahydropyrimidine (MTNP) has been synthesized during this work by nitration of 1,3-di-tert-butyl-5-nitro-5-methyl hexahydropyrimidine with fuming nitric acid. The synthesized molecule (MTNP) has been characterized by elemental analysis, IR, H and C NMR spectroscopy. TG of the compound showed two-step...

After improving the preparation of the azimines 9 (a = methyl, b = ethyl ester), we reinvestigated the mild thermolysis of 9 to 13 in CDCh: Unlike previously postulated, the azimines 9 first undergo a 1,4-H migration to the triazones 14 (step a), which suffer an elimination to yield the diazenes 16 (step b), which, in turn, are finally transformed by a 1,3-H migration to the carbazates 13 (step...

Thermochemical processing methods such as pyrolysis are of growing interest as a means of converting biomass into fuels and commodity chemicals in a sustainable manner. Macroalgae, or seaweed, represent a novel class of feedstock for pyrolysis that, owing to the nature of the environments in which they grow coupled with their biochemistry, naturally possess high metal contents. Although the imp...

Gold(I) halides, including AuCl and AuBr, were employed for the first time as precursors in the synthesis of Au nanoparticles. The synthesis was accomplished by dissolving Au(I) halides in chloroform in the presence of alkylamines, followed by decomposition at 60 degrees C. The relative low stability of the Au(I) halides and there derivatives eliminated the need for a reducing agent, which is u...
