The general format for an isotope using this tool is , where X is an elemental symbol, A is the mass number, and Z is the atomic number. The Isotope tool can be used in much the same way as the Superscript and Subscript tools. The problem below asks us to complete the given ...
(1st level), PG fingerprints track the occurrence of a fixed set of atomic fragments (or motifs)21. The block scale (2ndlevel) uses the Quantitative Structure-Property Relationship (QSPR) fingerprints18,44for capturing features on larger length-scales as implemented in the cheminformatics toolkit...
Evolution of the atomic charges of the main atoms involved in the reaction (a), the total molecular charge of each of the reactants (b), and the electron delocalization between the terminals atoms (1,3 and 4,7) of both species (c). Atomic or molecular charges are denoted asQ, wherea...
Because chemical pattern representations are relatively new, the number of interfaces where the user can graphically create patterns is limited. Examples of editors to handle SMARTS notation are MarvinSketch [29], JSME [44], SMARTeditor [45], and the PubChem’s Sketcher web editor [46,47]. ...
Nevertheless, in contrast to the structure and composition of bacteria, viruses have no cell wall, cell membrane, cytoplasm and nucleus, and they have only capsid and genetic material (RNA or DNA) [46]. Hence, the interaction mechanism between virus and metal may be different from that of ...

Self-assembly simulations of large numbers of different HS molecules might soon become a reality, opening up the opportunity to study and quantify atomic-level properties within realistic HS supramolecular structures. More generally, the study of HS in the foreseeable future will have great relevance ...
Strain analysis from high-resolution transmission electron microscopy (HRTEM) images offers a convenient tool for measuring strain in materials at the atomic scale. In this paper we present a theoretical study of the precision and accuracy of surface str
An RNA excited conformational state at atomic resolution Article Open access 19 December 2023 Introduction Chemical shift is the most valuable observable in NMR spectroscopy. It is easily accessible, can be precisely measured with high reproducibility, and most importantly is exquisitely sensitive to ev...
