(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-02-19)
The master degree work presented is a result of a research conducted together with
a group, which has worked on the modification of the synthesis CTA-MCM-41, that silica
belongs to the mesoporous materials family (composed ...
The Helmholtz equation with impedance in a half-space
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2005)
In this Note we obtain existence and uniqueness results for the Helmholtz equation in the half-space R-+(3) with an impedance or Robin boundary condition. Basically, we follow the procedure we have already used in the ...
Electron Tunneling Excitation of a Coupled Two Impurity System
(Springer, 2018)
Kondo effects in individual atoms, molecular magnets or quantum dotshave received a lot of attention. Systems with two units, like double quantum dotsor two atoms, have also attracted some attention due to the interplay ...
Synthesis, characterization and optical properties of 1–4 nm size silicon nanoparticles
(Asociación Química Argentina, 2020-07)
Silicon nanoparticles (SiNp), particularly nanoparticles of diameter 1–4 nm, combine high quantum yield photoluminescence, the capacity for reactive oxygen species generation, and the richness of silicon surface derivatization. ...
Environmental catalysis and the chemistry of SO2 on oxide surfaces: fundamental principles for the cleavage of S-O bonds
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Uso de óleo pós-fritura para produção econômica de bioemulsificante e biotensoativo por mucor hiemalis UCP 0039 isolado de solo da caatinga (PE, Brasil).
(Universidade Católica de Pernambuco, 2019-11-05)
Surfactants / surfactants are amphiphilic compounds that have as their main feature the ability to reduce surface tension. Emulsifiers do not necessarily reduce surface tension, however they are excellent in their ability ...
