Photostability of different chlorine photosensitizers
(WILEY-V C H VERLAG GMBH, 2008)
In this paper, we report the photodegradation of three different chlorine photosensitizers (Photoditazine (R), Radachlorin (R), and Foscan (R)). The photosensitizer degradation was analyzed by changes in the fluorescence ...
Dihydroeuparin as sunscreen
(Sociedad Chilena de Quimica, 2000)
Physicochemical parameters, ε, λ, solubility in water and Brij-35, pKa, Ka and photostability for dihydroeuparin, 5-acetyl-2, 3-dihydro-6-hydroxi-2-isopropenyl-benzo (b) furan (from Senecio Graveolens), were obtained and ...
DIHYDROEUPARIN AS SUNSCREEN
(Sociedad Chilena de Química, 2000)
Desonida: validação de métodos analíticos e estudo de fotoestabilidade de formulações
(Universidade Federal de Santa MariaBRFarmáciaUFSMPrograma de Pós-Graduação em Ciências Farmacêuticas, 2013-04-26)
Desonide is a nonfluorinated corticosteroid with glucorticoid activity. It is used
topically in the treatment of atopic dermatitis, inflammation, pruritus and seborrheic
dermatitis of mild to moderate severity. In Brazil, ...
Evaluation of intramolecular energy transfer process in the lanthanide(III) bis- and tris-(TTA) complexes: Photoluminescent and triboluminescent behavior
(Elsevier Science BvAmsterdamHolanda, 2008)
Can efficiency of the photosensitizer be predicted by its photostability in solution?
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2009)
We have investigated a possible correlation between the photostability and photodynamic efficacy for different photosensitizers; hematoporphyrin derivatives and chlorines. To perform such analysis, we combined the depth ...
Assay of caffeoylquinic acids in Baccharis trimera by reversed-phase liquid chromatography
(Universidad de Belgrano. Facultad de Ciencias Exactas y Naturales. Proyectos de Investigación, 2012)
Baccharis trimera commonly named ‘carqueja’, is wide-spread in South America and are used as raw material for herbal medicines. A reversed-phase liquid chromatography (RP-LC) method coupled to diode array detector was ...
Characterization and stability study of a water-in-oil microemulsion incorporating quercetin
(TAYLOR & FRANCIS INC, 2011)
Background: The effectiveness of a water/oil (w/o) microemulsion containing quercetin against ultraviolet B radiation (UVB) induced damage was recently demonstrated by our group. However, during the development of new ...
A spectroscopic experimental and semi-empirical study of [Eu(salen)2] as a red-emitter for phosphor-converted UV LED
(2021-10-01)
Most of commercial WLEDs have a lack of red-emission component resulting in cool white illumination. Aiming this issue, in this paper, we present the synthesis of [Eu(salen)2] with a Schiff base type ligand, the salen ...
Langmuir and Langmuir-Schaefer films of poly(3-hexylthiophene) with gold nanoparticles and gold nanoparticles capped with 1‑octadecanethiol
(American Chemical Society - ACSWashington, DC, 2014-06)
This paper reports on the production of Langmuir films of regioregular poly(3-hexylthiophene) (P3HT) and their characterization by surface pressure isotherms and UV-vis in situ spectroscopy aiming at the best spreading ...
