Interconversion of Quadruply and Quintuply Bonded Molybdenum Complexes by Reductive Elimination and Oxidative Addition of Dihydrogen
A series of dimolybdenum dihydride complexes supported by amidinate ligands and featuring a Mo—Mo quadruple bond, MoII2, has been prepared and characterized by NMR spectroscopy and x-ray crystallography. UV irradiation (365 nm) of one of these complexes, namely the...
Selective UV Reflecting Mirrors Based on Nanoparticle Multilayers
Un nuevo tipo de espejo nanoestructurado que refleja selectivamente la radiación ultravioleta (UV) es presentado. Multicapas periódicas porosas con propiedades de cristal fotónico son construidas a través de la deposición capa por capa de suspensiones coloidales de...
Virus-like glycodendrinanoparticles displaying quasi-equivalent nested polyvalency upon glycoprotein platforms potently block viral infection
Ligand polyvalency is a powerful modulator of protein–receptor interactions. In particular, host–pathogen infection interactions are often mediated by glycan ligand–protein interactions. The study of these interactions using synthetic compounds with very high copy...
Cysteine-Generated Sulfide in the Cytosol Negatively Regulates Autophagy and Modulates the Transcriptional Profile in Arabidopsis
In Arabidopsis thaliana, DES1 is the only identified L-Cysteine desulfhydrase located in the cytosol, and it is involved in the degradation of cysteine (Cys) and the concomitant production of H2S in this cell compartment. Detailed characterization of the T-DNA...
Tuning Dichroic Plasmon Resonance Modes of Gold Nanoparticles in Optical Thin Films
A simple method is presented to tune the gold Surface Plasmon Resonance (SPR) modes by growing anisotropic nanoparticles into transparent SiO2 thin films prepared by GLADPVD. In this type of composite film, the anisotropy of the gold nanoparticles, proved by different...
