Percent composition is also useful for evaluating the relative abundance of a given element in different compounds of known formulas. As one example, consider the common nitrogen-containing fertilizers ammonia (NH3), ammonium nitrate (NH4NO3), and urea (CH4N2O). The element nit...
The fast and accurate determination of molecular properties is highly desirable for many facets of chemical research, particularly in drug discovery where pre-clinical assays play an important role in paring down large sets of drug candidates. Here, we present the use of supervised machine learning ...
Faba bean (Vicia faba L.) is an important protein-rich fodder crop, which is widely cultivated in temperate areas. However, antinutritional compounds such as condensed tannins, limit the use of this protein source in monogastric feed formulations. Previous studies demonstrated that two recessive an...

Identifying sources of nitrate contamination has been a long-term challenge in areas with different land uses. We investigated the biogeochemical processes and quantified the contribution of potential nitrate sources in the Nanyang Basin, the source area of the South to North Water Diversion Project in...

DETAILED DESCRIPTION OF THE INVENTIONThe invention relates to compounds, reagents and methods for determining cations in a sample. The invention allows quantitative determination of cations in blood serum and other...
In addition, although a dry phase chemistry test strip utilizing a dye, such as tetrabromophenol blue or tetrachlorophenol-3,4,5,6-tetrabromosulfonephthalein, has been used extensively for several years, no dry phase test strip has utilized a test pad comprising a film, membrane or layer of...
