Medicinal plants: Influence of environmental factors on the content of secondary metabolites
(2017-10-31)
Current research in secondary metabolites from medicinal plants should take into account the prevalence and the healing properties of which plant. These compounds have been provided opportunities to development of new drugs ...
Synthesis of PbTiO3 by use of polymeric precursors
(1998-09-01)
Lead titanate powders were synthesized through the use of polymeric precursors according to the Pechini Process. The polymeric precursor was calcined at temperatures ranging from 300 to 600°C for 1 or 2 h. X-ray diffraction ...
EPR study of local symmetry sites of Ce(3+) in Pb(1-x)Ce(x)A (A=S, Se, and Te)
(AMER PHYSICAL SOC, 2009)
The local site symmetry of Ce(3+) ions in the diluted magnetic semiconductors Pb(1-x)Ce(x)A (A=S, Se, and Te) has been investigated by electron-paramagnetic resonance (EPR). The experiments were carried out on single ...
Spontaneous long and short-range ferroelectric ordering in Pb(0.55)La(0.30)TiO(3) ceramics
(AMER INST PHYSICS, 2010)
In this work, we investigated the temperature dependence of short and long-range ferroelectric ordering in Pb(0.55)La(0.30)TiO(3) relaxor composition. High-resolution x-ray powder diffraction measurements revealed a clear ...
Antilocalization of hole carriers in Pb(1-x)Eu(x)Te alloys in the metallic regime
(AMER PHYSICAL SOC, 2009)
Magnetoresistance measurements in p-type Pb(1-x)Eu(x)Te alloys, for x varying from 0% up to 5%, have been used to investigate localization and antilocalization effects. These are attributed to both the spin-orbit scattering ...
Design, Synthesis, and Characterization of N-Oxide-Containing Heterocycles with in Vivo Sterilizing Antitubercular Activity
(2017-10-26)
Tuberculosis, caused by Mycobacterium tuberculosis (Mtb), is the infectious disease responsible for the highest number of deaths worldwide. Herein, 22 new N-oxide-containing compounds were synthesized followed by in vitro ...
