“…The crystallite size estimated from Scherer's equation and W-H plots was found to be in the range ~25 nm. A small difference was observed in the estimated crystallite size determined from Scherer's equation [1]. The variation in the size was due to the fact that in Scherer's equation the strain component was presumed to be zero.…”

“…Yttrium oxide (Y2O3) received important attention in the latest years in view of its possible integration into a wide range of scientific and technological applications such as luminescent displays, photoelectric devices, optoelectronics devices, biological, chemical probes etc., [1,2]. Nanostructured Y2O3 shows outstanding physical properties such as wide energy band gap (~ 5.30 eV), high dielectric constant, optically isotropic and refractive index of about 1.91 [3][4][5].…”

“…The facile bio-combustion method using Aloe vera plant extract as a fuel/surfactant offers a facile mode for low rate and large-scale assembly. Aloe vera plant known as sensitive plant scattered throughout in India in moist locality [1]. Present work focus on the synthesis of series of Mg 2+ (1-11 mol%) doped Y2O3 NPs with different morphologies prepared via bio approach.…”

For the first time green route method was used to synthesize pure and Mg 2+ (1-11 mol%) doped Y2O3 nanophosphors by using Aloe vera leaves extract as a fuel. The final product was well characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and diffuse reflectance spectroscopy (DRS). The PXRD pattern reveal that the formation of single phase, cubic structure of Y2O3 with crystallite sizes ~25 nm. The SEM results showed porous and agglomerated structures. TEM images showed the crystallite size of the material and were found to be around ~ 25 nm. DRS studies revealed that the band gap of the nanophosphors was found to be around 5.82 to 5.87 eV.

“…In recent years, studies have revealed that the addition of nano-reinforcements such as oxides (Al 2 O 3 [7,8], TiO 2 [9], Y 2 O 3 [10], ZnO [11] and ZrO 2 [12]), carbides (SiC [13], B 4 C [14] and TiC [15]), nitrides (BN [16], AlN [17] and TiN [18]), borides (TiB 2 [19], SiB 6 and ZrB 2 [20]), CNT [21] and graphene [22], helped to simultaneously improve the yield strength and ductility of magnesium. In these studies, a small volume fraction of approximately 1 to 2 volume percent of nano-size reinforcements have been shown to produce results comparable or even superior to that of MMCs containing a much higher volume fraction of micron size reinforcements.…”

Magnesium is the lightest structural metal that can be used for engineering applications and its non-toxic nature makes it attractive for use as a biomedical implant. The judicious addition of nanoparticles to magnesium assists in enhancing multiple engineering properties that are critical for its widespread use and are superior to that exhibited by conventional micron-size particles containing composites. The ability to improve mechanical properties with the use of smaller volume fraction of reinforcements while keeping density low makes magnesium nanocomposites an attractive choice for lightweight engineering and bio-resorbable biomedical applications. In view of the exceptional response of magnesium in presence of nano-length scale reinforcements, an attempt is made in this paper to provide a brief review of characteristics of several magnesium nanocomposites illustrating the effects of ceramic and metallic reinforcements to enhance mechanical properties.
