A novel non-metallic element of the sulphur group is named, "sulphenium". It is present in diamond, together with carbon. Its presence is shown by reacting pure Fe with diamond, and treating the product with an acid, yielding a gaseous cpd. with properties similar to H2S, but giving a...
The relationship of solvent parameters to metal reactivity is discussed.I t was reported earlier ... NK Graham - 《Dalton Transactions》 被引量: 0发表: 1983年 Synthesis of Polymers in Aqueous Solutions: Heterogeneous Oxidation of Poly(Amide-Sulphide) in Water The heterogeneous oxidation of N-(2...
Extensive reporting on key chemicals markets is one reason why ICIS is the first choice for market intelligence for sulphur decision-makers in high volume markets such as China, Europe, the Middle East and Canada. Our price reports and market fundamentals support key decisions every day. ...
We show that the S Kβ emission spectrum is a sensitive probe of the protonation state of the acid molecules. Using non-negative matrix factorization we are able to extract the fractions of different protonation states in the spectra and the results are in good agreement with the simulation ...
Nevertheless, development of all solid-state Li–S batteries is still largely limited owing to lack of solid electrolytes with conductivity comparable to that of liquid electrolytes. Polysulphide dissolution represents a common, but not the sole reason for the capacity decay of sulphur cathodes. ...
Autometallographic (AMG) silver enhancement is a potent histochemical tool for tracing a variety of metal containing nanocrystals, e.g. pure gold and silver nanoclusters and quantum dots of silver, mercury, bismuth or zinc, with sulphur and/or selenium. These nanocrystals can be created in many ...
For this reason, it is interesting study the nature of crystalline phases in alkali-promoted V2O5 catalysts after the catalytic tests. Fig. 7 shows the XRD pattern alkali metal-promoted V2O5(Fig. 7A) and Na-promoted catalysts 7B). Diffraction peaks at 2? = 10.8, 13.8, 21.6, 27.7, 33.9,...
However, it has been found that some of the dirtiest samples of used baths give low results when boiled for only 2 minutes and give a maximum titration when boiled for 6 minutes. For this reason the preferred time of boiling or heating is 6 minutes. It will be understood, of course, ...
The invention relates to apparatus for the manufacture of pig iron and the production of steel, and particularly to the desulphurization of pig iron. This application is a continuation in part of my a
