Nobel Prize in Chemistry 2014 – How the optical microscope become a nanoscope

by Dr. Pedro Paulo and Prof. Sílvia B. Costa Last week, Eric Betzig, Stefan W. Hell and William E. Moerner were awarded the Nobel Prize in Chemistry 2014 “for having bypassed a presumed scientific limitation stipulating that an optical microscope can never yield a resolution better than 0.2 micrometres.”[1] It is commonly known that it is not possible to “see” objects smaller than the wavelength of light. This concept was scientifically formulated at the end of the nineteenth century by Ernst Abbe [2] and Lord Rayleigh [3] as the “diffraction limit”. For optical…Read more

A paper by I. Correia and J. Costa Pessoa was the cover of Eur. J. Inorg. Chem.

The paper "Vanadium Complexes as Prospective Therapeutics: Structural Characterization of a VIV Lysozyme Adduct" co-authored by Marino F. A. Santos, Isabel Correia, Ana R. Oliveira, Eugenio Garribba, João Costa Pessoa and Teresa Santos-Silva was invited for the cover of  issue 21/2014 of Eur. J. Inorg. Chem. The cover image shows a representation of the HEWL–VIVO(pic)2 adduct (HEWL: hen egg white lysozyme; pic: picolinato). http://onlinelibrary.wiley.com/doi/10.1002/ejic.201402605/fullRead more
