Tuning of structural and magnetic properties of La1−xSxMnO3
(2018)
This thesis investigated the effect of incorporation of Sr2+ and Ca2+ ions on the structural and magnetic properties of LaMnO3 (LMO) powders synthesized by sol-gel and thermal treatment method at 900°C. X-ray diffraction ...
Evaluation of waste tire crumb rubber and dewatered sludges as adsorbents of heavy metals ions in the Miradero Water Treatment Plant at Mayagüez, Puerto Rico
(2014)
Water pollution by heavy metal species is a major environmental concern, and existing technologies are not always adequate for meeting regulatory limits. Major sources of pollution of aqueous effluents with heavy metal ...
Preparation of copper-bearing nanofluids for thermal applications
(2008)
Stable suspension of nanometer solid particles in suitable solvents, so-called nanofluids, has shown enhanced thermal conductivity when compared with the fluid base; therefore, the preparation and characterization of these ...
Tuning of multifunctional properties of undoped and doped BiFeO3
(2018)
This work studied the effect of the incorporation of Co2+ and Mn2+ species on the structural and magnetic properties of nanocrystalline powders of BiFeO3 (BFO) synthesized by the sol-gel and thermal treatment method at ...
The role of Ca+2 doping on the structural, magnetic and electrical properties of bismuth ferrite powders and films
(2018-07)
The search for alternative ways of collecting, storing and reusing energy has motivated our research to investigate multifunctional materials based on the perovskite structure, such as Bismuth ferrite (BFO). Our scope was ...
