2023, Journal of Organometallic Chemistry Citation Excerpt : The bridging thiolate moiety would affect the reactivity of the iron-alkenyl bond. The alkenyl moiety of the SC6H4CHCH ligand in 1 is restricted by the C,S-chelate structure, whereas the simple alkenyl ligands are not constrained and ...
This is because of the hexagonal structure of ice mimics hexagonal bonds. Parts per thousand Salinity is often expressed this way. The average salinity of water is 34.7%. Principle of constant proportions The major dissolved constituents responsible for the salinity of seawater occur nearly everywhere...

These sources can be categorized by their effect: – statistical correlations, resulting from the propagation of the raw distribution statistical uncertainties through unfolding process, their characteristics largely depend on the response matrix structure; – fully correlated shift of the distribution as ...
Properties of VaR Value at risk satisfies some basic properties that help characterize its structure and clarify the degree to which it is a useful measure of risk. First, VaR is easily understood, and it intuitively reflects potential loss. Second, VaR depends only on the left tail of...
