Novel Coumarin-Quinoline Hybrids: Design of Multitarget Compounds for Alzheimer's Disease
(2019)
Alzheimer's disease (AD) is the most prevalent neurodegenerative disease, presenting the most devastating consequences on human health and life quality. Coumarin-quinoline hybrids were synthesized following a very efficient ...
Structural phase evolution of strontium-doped lead titanate thin films prepared by the soft chemical technique
(2003-03-01)
Strontium-modified lead titanate thin films with composition Pb1-xSrxTiO3 were grown on Pt/Ti/SiO2/Si substrates using the polymeric precursor method. The structural phase evolution as a function of the Sr contents was ...

Phase Characterization of Lead Zirconate Titanate Obtained from Organic Solutions of Citrates
(1992-01-01)
Lead zirconate titanate (PZT) with several Zr/Ti ratios was prepared by the organic solution of citrates of the respective cations. The Rietveld method was applied to perform quantitative analysis of the coexisting phases. ...
Spectroscopic study of lanthanide squarate hydrates
(1994-12-01)
In the present investigation some spectroscopic properties of several lanthanide squarate hydrates are reported. The Raman spectra show the same distinctive Jahn-Teller intensity pattern for non-totally symmetric modes, ...

Computer assisted design of potentially active anti-trypanosomal compounds
(ELSEVIER SCIENCE BV, 2002-04-26)
A computer assisted molecular modeling was used to design molecules having a shape complementary to the active site of glutathione reductase (GR) and trypanothione reductase (TR). The designed 5-nitro compound derivatives. ...
