Singlet oxygen production by a crude oil from the San Jorge Gulf Basin, Argentina
(Wiley Blackwell Publishing, Inc, 2018-11)
The quantum yields for singlet oxygen production by diluted solutions of an Argentine crude oil and its SARA (saturates, aromatics, resins and asphaltenes) fractions were obtained by direct detection of the characteristic ...
Singlet oxygen production from excited singlet and triplet states of anthracene derivatives in acetonitrile
(1995)
The efficiencies of singlet oxygen production from the singlet and triplet states of a series of anthracene derivatives in acetonitrile are reported. For anthracene and for all of the anthracene meso derivatives studied, ...
Synthesis of 2-(n-(N,N,N-trimethyl)-n-alkyl)-5-alkylfuryl halides. Useful probes for studying singlet oxygen dynamics and equilibria in microcompartmentalized systems
(2004)
Three lipid-soluble furan derivatives, 2,5-disubstituted with different n-alkyl chains, and a terminal trimethylammonium group were obtained by reaction of a metalated monoalkylfuran with alkyl dihalides under conditions ...
Interparticle Delivery and Detection of Volatile Singlet Oxygen at Air/Solid Interfaces
(American Chemical Society, 2021-03)
An interparticle system has been devised, allowing airborne singlet oxygen to transfer between particle surfaces. Singlet oxygen is photogenerated on a sensitizer particle, where it then travels through air to a second ...
Physicochemical characterization of water-soluble chitosan derivatives with singlet oxygen quenching and antibacterial capabilities
(Elsevier Science, 2017-04)
New water-soluble chitosan derivatives (WSCh) were obtained by Maillard reaction (MR) between glucosamine (GA) with both low and medium molecular weight chitosans (Ch). The WSCh showed larger solubility than the respective ...
Antioxidant β-carotene does not quench singlet oxygen in mammalian cells
(American Chemical Society, 2013-01)
Carotenoids, and β-carotene in particular, are important natural antioxidants. Singlet oxygen, the lowest excited state of molecular oxygen, is an intermediate often involved in natural oxidation reactions. The fact that ...
Synthesis of 2-(n-(N,N,N-trimethyl)-n-alkyl)-5-alkylfuryl halides - Useful probes for studying singlet oxygen dynamics and equilibria in microcompartmentalized systems
(ELSEVIER SCIENCE SA, 2004-12-01)
Three lipid-soluble furan derivatives, 2,5-disubstituted with different n-alkyl chains, and a terminal trimethylammonium group were obtained by reaction of a metalated monoalkylfuran with alkyl dihalides under conditions ...
Singlet oxygen quenching by anthocyanin's flavylium cations
(Informa HealthcareLondonInglaterra, 2008)
Singlet oxygen quenching by anthocyanin's flavylium cations
(Taylor & Francis, 2008-12)
The quenching of singlet molecular oxygen (1O2) by the flavylium cation form of six widespread anthocyanin derivatives: cyanidin 3-glucoside (CG), cyanidin 3-rutinoside (CR), cyanidin 3-galactoside (CGL), malvidin (M), ...
