The present paper looks at two extremes of Markush structures, which are unsearchable as such, the so-called "A-B-C type molecules" and "too simple compounds". Appropriate patentability search strategies, including non-unity and incomplete searches, are defined. Frequently, claimed Markush formula...
a chemical formula shows the elements that make up the compound and the numbers of atoms of each element in the smallest unit of that compound, be it a molecule or a formula unit. knowing the names of the elements and a few basic rules allows us to name simple compounds given the ...
Compounds featuring a bond between a Group 13 (M) and a Group 15 element (N or P) and with the formulae HmMNHn and HmMPHn: structural aspects and bonding Following studies of the thermal and photoactivated reactions of the Group 13 metal atoms Al, Ga or In (M) with NH3 or PH3 in...
Stopping powers and ranges of electrons and positrons Tables of stopping powers and related data are given for electrons in 37 elements and 60 compounds, and for positions in 8 materials. The tables include (1... Martin J. Berger,Stephen M. Seltzer - 《Unknown》 被引量: 183发表: 1982年...

It was found that a total of 69 compounds were identified in YCHD, where 41 of them were absorbed into the blood. Furthermore, 34 biomarkers in the urine were identified from dampness-heat jaundice syndrome. Of note, the plotting of the correlation between marker metabolites and serum ...
Mangrove pore water was sampled from mangroves at the Caeté Estuary, near the town of Bragança in Northern Brazil (0.9°S, 46.7°W; Fig. 1). This mangrove forest ( Properties of C18-extracted DOM in Electrospray Ionization FT-ICR-MS The general mass distributions of compounds which were ...
Molecular values may be ionized with a positive or negative integer charge. For unit charges, a unary+or-may prefix aMolecularvalue, e.g.+Naor-C[2]*H[3]*O[2](acetate). The charges of ions or ionic compounds will be added when combined, so+Na*(-Cl)(salt) will produce the charge...
Today’s nuclear medicine methods form a new standard for GFR measurements because of its easily assayed, radiolabeled and stable compounds that meet the criteria of a good GFR marker, namely clearance only by glomerular filtration without tubular secretion and extra-renal elimination. The most ...
LC-MS is a powerful analytical method for identification of known compounds and elucidation of unknown compounds in TCM complex matrix5–8, such as TCM formulae. On account of constituent diversity, molecular com- plexity and limitations of analysis technics, only some relatively simple or ...
