polyhedral shapes in a variety of colours

Research being carried out by Professor Di Sun, from Shandong University, and Professor Stan Schein, from UCLA, unites two research streams. In the first, they synthesized Ag90, a Keplerian nest with one icosahedral and two octahedral shells. In the second, they realized that the nesting maximized the number of shared axes of rotation, just how the late mathematician John Conway […]

Seeing the structures of molecules: insights from NMR and industry

Written by

Professor Anthony Serianni's work centres around identifying the structure of molecules, which remains a key challenge within modern chemistry.

Many of the essential chemical constituents of life, including carbohydrates, are made up of complex atomic arrangements. Knowing the particular structure of a compound is important not only for identification purposes, but also for understanding how biologically relevant compounds react. Through this knowledge, their biological functions can ultimately be deciphered. Professor Anthony Serianni at the University of Notre Dame has […]
