Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...
Optimization and application of the quantum adiabatic theorem, and the quantum origin of classical interference
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-03-29)
In this master’s thesis, we developed three different topics. In the first topic, we studied the quantum adiabatic brachistochrone method (QAB) for optimizing adiabatic dynamics. In the first part of this study, we reported ...
Facile Synthesis and Photophysical Characterization of New Quinoline Dyes
(2017-01-01)
This paper describes the synthesis of new quinoline derivatives, molecules that has been long interest in the organic and medicinal chemistry. Through the Multicomponent Reaction (MCR), an important tool in modern synthetic ...
Linear relationship between emission quantum yield and Stokes shift in 3-styryl aza-coumarin based dyes in the presence of cyclodextrins
(2023)
The effect of the cyclodextrins inclusion on the Stokes shifts and emission quantum yield of three 3-styryl aza-coumarin dyes (SACs) was experimentally and theoretically studied. Preliminary results show a relationship ...
Sn4+complexation with sulfonated-carbon dots in pursuit of enhanced fluorescence and singlet oxygen quantum yield
(2020-06-07)
Here we report a novel strategy to crosslink the surface of sulfonated-carbon dots (S-CDs) by complexing SnCl4with sulfonate groups (-SO3-) on the CDs in aqueous solution. The S-CDs show an average photoluminescence (PL) ...
Effect of ionic liquid in a pressurized reactor to enhance CO2 photocatalytic reduction at TiO2 modified by gold nanoparticles
(2022-01-01)
This work describes the synergic effect of gold nanoparticles as co-catalyst on TiO2 nanotubes (TNT/AuNP) in aqueous medium containing the ionic liquid (IL) 1-Butyl-3-methylimidazolium tetrafluoroborate, in a pressurized ...
Fluorescence Quantum Yields in Complex Environments from QM-MM TDDFT Simulations: The Case of Indole in Different Solvents
(American Chemical Society, 2020-11)
Fluorescence is commonly exploited to probe microscopic properties. An important example is tryptophan in protein environments, where variations in fluorescence quantum yield, and in absorption and emission maxima, are ...
