[C.A. 61, 11032] that precisely such biocidal mixtures very often fail to bring about the desired effect. For example, the (1:1) mixture of (n-C4H9)3SnCl and [(n-C4H9)3Sn]2O exhibited a certain synergism, whereas the (1:1) mixture consisting of (n-C4H5)SnCl and (n-C4H9)2...
Note that the conductance obtained from the increasingly oxidized samples approaches the value meas- ured on the graphene-removed sample. In addition to the observation of the large spatial non-uniformity in both the conductance and Raman signatures from the longer-processed graphene, the roughly ...

However, as shown by Farsalinos and Rodu [66], they miscalculated in their Equation (1) the daily intake of these metals, as their conversion of μμg/kg concentrations from chemical analysis into air density concentrations in mg/m3m3 (for comparison with the environmental ATSDR reference ...
Titanium is a shiny gray metal with a low corrosion rate and high strength. It is a very useful metal for its refractory properties due to its high melting and boiling points. Titanium metal compounds include oxides, sulfides, alkoxides, nitrides, carbides, etc. ...
