The reaction was also monitored by thin layer chromatography. The retention coefficient (R f) of the compound N-chlorinated (0.48) is much higher than the substrate (0.24) using hexane/ethyl acetate ...

Even though several plants of this genus had already been investigated, the use of a simple bioassay was able to guide the chemical fractionation to a new bioactive naphthoquinone. Thus, besides ...

Beginning in the late 1970s, he effectively became a master builder in the nano universe — seeking how to use molecular bonds to fashion biological structures designed with a special purpose.

The first fraction was eluted using hexane, and a second fraction was extracted using ... While the alkane data provide a broad picture of local abundances of xeric vegetation structure, they do not ...

Capital structure is the mix of debt and equity that fund a company's operations. A judicious use of debt and equity is a key indicator of a strong balance sheet. A healthy capital structure that ...
