Alarcon, Rafael Turra [UNESP]; Gaglieri, Caroline [UNESP]; dos Santos, Giovanny Carvalho [UNESP]; Roldao, Juan Carlos [UNESP]Made available in DSpace on 2021-06-25T11:14:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; This work investigates in depth the thermal degradation process of a polymer of urethane dimethacrylate (UDMA). UDMA monomer has been widely used in dental restorations and biomaterials. The use of density functional theory (DFT) calculations provided the bases for understanding the structure and reacti...
Environmental effects in nitroquinoline derivatives solutions: Solvatochromism,...
dos Santos, Giovanny Carvalho [UNESP]; Rodrigues, Julia Lopes [UNESP]; Moreno, Vitor Fernandes [UNESP]; da Silva-Filho, Luiz Carlos [UNESP]Made available in DSpace on 2021-06-25T10:25:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-07-05; Since the first chemical fluorescent sensor reported in 1867, it has often been sought to find intelligent organic molecules that act as chemical sensors of high selectivity and sensitivity. In this process, the colorimetric and fluorescence methods have more advantages, as they are generally very sensi...
Combined Spectroscopic and TD-DFT Analysis to Elucidate Substituent and Acidoch...
dos Santos, Giovanny Carvalho [UNESP]; Roldao, Juan Carlos; Shi, Junqing; Milián-Medina, Begoña; da Silva-Filho, Luiz Carlos [UNESP]Made available in DSpace on 2020-12-12T01:33:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; A combined spectroscopic and TD-DFT case study was performed, to identify a robust method to calculate the complex near UV/Vis absorption spectra of various amino- vs. nitro-substituted 2,4-diphenylquinolines, which vary strongly under neutral and successively acidic conditions. For this, different DFT ...
