Exalted photocatalytic activity of tetragonal BiVO4 by Er 3+ doping through a luminescence cooperative mechanism
(Royal Society of Chemistry (Great Britain), 2014)
Er-doped BiVO4 are synthesized by means of a surfactant free microwave assisted hydrothermal method having good photoactivities under sun-like excitation for the degradation of methylene blue. From the structural and ...

Scission kinetic model for the prediction of polymer pyrolysis curves from chain structure
(Elsevier, 2014)
There is a significant interest in correlating polymer structure with thermal degradation behavior. Thus, polymer pyrolysis curves could be predicted from the chemical structure of the polymer. Recent proposals correlate ...

Direct mechanosynthesis of pure BiFeO3 perovskite nanoparticles: reaction mechanism
(Royal Society of Chemistry (Great Britain), 2013)
In this work, a mechanochemical procedure is proposed as a simple and fast method to synthesize the pure BiFeO3 perovskite phase as a nanostructured material without the need for purification treatments, while the ...

Electrical properties of stoichiometric BiFeO3 prepared by mechanosynthesis with either conventional or spark plasma sintering
(Wiley, 2013)
Phase-pure powders of stoichiometric BiFeO3 have been prepared by mechanosynthesis. Ceramics sintered by either conventional heating in air or spark plasma sintering (SPS) followed by oxidative anneal in air are highly ...

Processing and characterisation of cermet/hardmetal laminates with strong interfaces
(Elsevier, 2014)
Cemented carbides and cermets are potential materials for high speed machining tools. However, cemented carbides are not chemically stable at high temperature and cermets present poor fracture toughness. Novel cermet/hardmetal ...
