We propose a set–valued framework for the well–posedness of birth– and–growth process. Our birth–and–growth model is rigorously defined as a suitable combination, involving Minkowski sum and Aumann integral, of two very general set–valued processes representing nucleation and growth respectively. The simplicity of the used geometrical approach leads us to avoid problems arising by an analytical...

1,3-B–H addition of various boranes over a W–N?N motif has been explored to probe its scope and limitations as method for N2 borylation. The reaction can be catalysed or not, that undergo retrohydroboration react monoalkylboranes.

The H-point standard addition method (HPSAM) was applied to the simultaneous determination of Bi(III) and Sb(III). This method is based on the difference in the absorbance of complexes of Bi(III) and Sb(III) with iodide in acidic media in different wavelength pairs. The results showed that Bi(III) and Sb(III) can be determined simultaneously with concentration ratios of 15:1 to 1:20. First-deri...
