Hydrogen peroxide disproportionation: time-resolved optical measurements of spectra, scattering and imaging combined with correlation analysis and simulations

Autor: Mohamed Ibrahim, Rene Nome

We study how time-dependent optical measurements of spectra, scattering, and imaging can be used to add to the understanding of heterogeneous reactions, compared to work performed using tools developed for homogeneous reactions. Using hydrogen peroxi

On the Fly' Characterization of YbIII:ErIII Co-Doped Upconversion Nanoparticle Nonlinear Optical Response from Single-Particle Trajectories

Autor: RENE NOME, Beatriz C. Barja, Paulo Cesar de Sousa Filho, Fernando Sigoli, María Claudia Marchi, Isabela Cavalcante

Spectroscopic characterization of individual nanoparticles is essential for understanding their structure-property relationship and for applications. Upconversion nanoparticles (UCNPs) in condensed phases can undergo both nonlinear optical and stocha

Time-Resolved Study of Light-Induced Ground State Proton Transfer from Acid Medium to 4-Nitrophenolate

Autor: Leandro Scorsin, Leticia Martins, Haidi Fiedler, Faruk Nome, RENE NOME

In the present work, we study the transient laser-induced formation of 4-nitrophenolate (4-NPO-) in the ground electronic state and subsequent proton transfer reaction with acetic acid and water with numerical calculations and laser flash photolysis.
