Journal ArticleDOI
Solution combustion synthesis, energy and environment: Best parameters for better materials
TL;DR: The most important findings about SCS and the selection criteria for its main parameters are critically reviewed, in order to give useful guidelines to those scientists who want to use this methodology for preparing materials with improved or new functional properties.
Journal ArticleDOI
Magnetic, Ferroelectric, and Magnetocapacitive Properties of Sonochemically Synthesized Sc-Doped BiFeO3 Nanoparticles
TL;DR: In this paper, the synthesis of undoped and Sc3+-doped BiFeO3 nanoparticles using the sonochemical technique was reported, where the substitution of Sc ions for Bi enhances the ferromagnetic as well as ferroelectric properties of this system.
Journal ArticleDOI
Phase transition and negative thermal expansion in A2(MoO4)3 system (A=Fe3+, Cr3+ and Al3+)
TL;DR: In this article, the negative thermal expansion coefficients of Fe 2 (MoO 4 ) 3, Cr 2 and Al 2 (Al 3 ) 3 compounds were investigated in static air in the temperature range of 298-1073 K by a thermo-dilatometer.
Journal ArticleDOI

TL;DR: In this paper, the phase transition at T_N (~643 K) as a function of particle size in multiferroic BiFeO3 system has been investigated using X-ray diffraction (XRD) studies.
Journal ArticleDOI
Copper(I) Oxide Nanocrystals – One Step Synthesis, Characterization, Formation Mechanism, and Photocatalytic Properties
Anshu Singhal,Mrinal R. Pai,Rekha Rao,Kodanthakurup T. Pillai,Ingo Lieberwirth,Avesh K. Tyagi +5 more
TL;DR: In this paper, two simple, one-pot, and low-cost chemical synthetic routes for the preparation of Cu2O nanocrystals were reported for hydrogen generation from water/methanol (2:1) mixtures under UV/Vis irradiation.
