The geometrical conception and current synthetic challenges of topological polymer chemistry have been reviewed. On the basis of the systematic classification and isomeric properties of polymer chain ...

Nuclear isomers are crucial probes for studying the structure of nuclei. Unlike chemical isomers—which have the same chemical formula but different arrangements of atoms—nuclear isomers are nuclei ...

(a) Schematic of imine bond formation. (b) The building block molecules chosen in this work (R: polyethylene glycol chain) and the construction of an extended network by imine bond formations through ...

Isomers are compounds with the same molecular formulae but different structural formulae. They have the same number of each type of atom. They can be part of the same or different homologous series, e ...

(Nanowerk News) Researchers at Tokyo Institute of Technology for the first time discovered the selective generation of three types of structural isomers (a set of different nanostructures with an ...

Isomers are molecules with the same formula but different chemical structures. Can be used to recap on isomers or could lead into a classroom discussion on nature’s chemistry.

Chemists from the University of Virginia in Charlottesville have developed a rotational spectroscopy technique that allows them to watch as a molecule alters the conformation of its constituent atoms.
