Spin effects in oxygen electrocatalysis: a discussion
(Elsevier Science, 2013-04)
The reduction of molecular oxygen in triplet and singlet spin states at metal electrodes is analyzed in the framework of quantum mechanical theory of charge transfer. Both outer- and inner-sphere mechanism is considered. ...
Sistemas híbridos formados por nanobastões de ouro e porfirinas: fotossensibilizadores promissores para terapia fotodinâmica
(Universidade Federal de Minas GeraisUFMG, 2018-07-11)
Gold nanostructures, spheres and rods, were synthesized to form a hybrid system with porphyrin H2TM4PyP(OTs)4 (POR) for application in photodynamic therapy (PDT) using light in the visible and near UV (UVA) spectral region. ...
A theoretical study of thionine: spin–orbit coupling and intersystem crossing
(2012-12-01)
A study of the possible intersystem crossing (ISC) mechanisms (S ⇝ T) in thionine (3,7-diamino-phenothiazin-5-ium), which is conducive to the efficient population of the triplet manifold, is presented. The radiationless ...
Evaluación del efecto antioxidante del Resveratrol sobre la criotolerancia de embriones bovinos de la raza Hartón del Valle producidos in vitro
(Universidad Nacional de ColombiaPalmira - Ciencias Agropecuarias - Maestría en Ciencias AgrariasFacultad de Ciencias AgropecuariasUniversidad Nacional de Colombia - Sede Palmira, 2021-07-07)
La raza Hartón del Valle pertenece al conjunto de razas bovinas criollas colombianas adaptadas a las condiciones del trópico, la cual, ha sido sometida a constantes cruzamientos con razas introducidas, reduciendo la población ...
