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 ...
Cinética de fotodegradação natural de contaminantes emergentes em ETE aeróbia
(Universidade Federal de São Carlos, 2019-02-26)
The advances in sample preparation and analytical detection techniques made possible the evaluation of a new class of contaminants found in the ug L-1 – ng L-1 range, known as Emerging Contaminants (EC). Along with that, ...
Complexos do tipo cis-[Ru(L-phen)2(apy)2]2+ com interesse no tratamento de Mal de Alzheimer: propriedades físico-químicas e estudos de inibição da Acetilcolina Esterase
(Universidade Federal de São Carlos, 2011-04-15)
The photochemical and photophysical properties of the cis-[Ru(phen)2(4apy)2]2+ complex where 4apy= 4-aminopyridine are reported. In this work the complexes are thermically stable throughout the course of many hours in ...
