Estudo computacional das interações entre nanopartículas de dióxido de titânio envolvidas no processo de coalescência orientada
(Universidade Federal de São Carlos, 2018-04-03)
Experimental and theoretical studies have shown that the aggregation of TiO2 anatase nanoparticles (NPs) occurs with preferential crystallographic orientation by the so-called oriented attachment mechanism (OA). The growth ...
Sintese e avaliação de peptidomiméticos contendo heterociclos de três membros como inibidores de catepsina L
(Universidade Federal de São Carlos, 2017-12-01)
Cathepsin L is a lysosomal cysteine protease, that is related to many physiological processes, however overexpression and up- or downregulation may cause several pathologies. Therefore, cathepsin L became an interesting ...
Síntese, caracterização de cocristais e sais-cocristais de ingredientes farmacêuticos ativos
(Universidade Federal de São Carlos, 2016-02-29)
Using techniques/procedures of green chemistry, solid state grinding,
solvent drop grinding and solvent drop grinding with heating, twenty compounds were
synthesized. Eleven compounds of dropropizine (antitussive): two ...
Diferenciação e caracterização química de espécies de Phyllanthus utilizando técnicas hifenadas
(Universidade Federal de São Carlos, 2016-01-15)
Several species of Phyllanthus genus are widely used in popular
medicine, even though very few phytochemical reports on species such as: P.
caroliniensis, P. stipulatus and P. tenellus are found in the literature. ...
Estudo de formação de tris-acetal internoe espiro-carbocíclicos a partir de (R)-(–)-e espiro-carbocíclicos a partir de (R)-(–)
(Universidade Federal de São Carlos, 2016-11-07)
In this work we studied, initially, the formation of the internal tris-ketals derivatives from their respective 2,2-bis-propargyl cyclic ketones from catalysis by gold complexes.
The reaction conditions were studied for ...
Estudo do processo de eletrofiação de micro/nanofibras de polímeros biodegradáveis para liberação do antibiótico Cloxacilina
(Universidade Federal de São Carlos, 2018-02-28)
Bovine mastitis disease is caused by some class bacteria and fungus from the environment, which affects the dairy cattle herd. This disease can cause financial damage to farmers by reducing cattle milk production. In this ...
Vidros fosfatos com tungstênio: incorporação de cátions alcalinos e sua influência nas propriedades estruturais e condutoras
(Universidade Federal de São Carlos, 2018-03-23)
Many glasses have been studied as solid
electrolytes in behalf of replacing commercial liquid electrolytes. However, even
for the best glass compositions available in the literature, values of conductivity
similar to ...
Estudos metabolômicos e biossintéticos visando contribuições para a química e taxonomia de microorganismos da família Xylariaceae
(Universidade Federal de São Carlos, 2014-11-11)
The PhD work aimed the exploration of fungal metabolism of NICL3 and NICL5, both initially identified as Xylaria sp., isolated as endophytic fungi from Cupressus lusitanica. The investigation of the NICL3 metabolism allowed ...
