The standard atomic weight of an element, Ar°(E), is the “recommended value of atomic weight (relative atomic mass) of an element revised biennially by the CIAAW and applicable to elements in any normal material with a high level of confidence” [10]. It is comprised of either an inte...
Armenium, triunoctium (Tuo), or tri-Californium is hypothetical chemical element with the symbol Arm and the atomic number 318. It is named after Armenia, a country in the South Caucasus region of Eurasia. Like all chemical elements with an atomic number greater than 82, Armenium has no ...
For several decades, the isotopic abundances of many elements with two or more stable isotopes have been measured with decreasing measurement uncertainty by means of mass spectrometry. As a result, the uncertainty in atomic-weight measurements, U[Ar(E)], has improved substantially. The Commission ...
A nucleus with a given N and Z is referred to as a nuclide. Nuclides with the same atomic number are isotopes , such as 12 C and 14 C, whereas nuclides with the same N, such as 14 C and 16 O, are called isotones. Nuclei such as 14 N and 14 C, which have the same mass ...
Artificial intelligence (AI) has been widely applied in drug discovery with a major task as molecular property prediction. Despite booming techniques in molecular representation learning, key elements underlying molecular property prediction remain large
In this case-control study, we investigated the associations of 11 EMEs [Calcium (Ca), potassium (K), magnesium (Mg), sodium (Na), manganese (Mn), selenium (Se), cobalt (Co), Molybdenum (Mo), copper (Cu), zinc (Zn), and iron (Fe)] in serum with the risk of schizophrenia. ...
(2021) reported a higher concentration of As, Cd, and Pb in infant formula from Lebanon with some samples being higher than the Codex Alimentarius standards. Other studies on baby foods in the USA have also found higher concentrations of As, Pb, and Cd in these sources of nutrition (...
Usually, laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis is equipped with a closed ablation cell. It cannot be used for non-destructive analysis of the large-size samples which exceeds the size of the cell. OBJECTIVES To realize directly in situ non-destructive ...
The biennial review of atomic weight determinations, A r (E), and other cognate data has warranted no changes for the standard atomic weights of the elements from that previously published in the Table of Atomic Weights 1995 with the exception of a new f
