Four different methods are adopted for optimization of particle size and desired morphology and the yttrium element in few phosphors is successfully replaced partially by other trivalent low cost elements such as Al, La, Gd and Bi.
Philpot et al. [79] and Booth et al. [80] were the first to report such observations and to layout the mathematical foundation, which is nowadays, referred to as the self-propagating high-temperature synthesis (SHS) [79, 80] or CS [81, 82].
Zhang et al. [114] studied the (Y, Gd)BO3: Eu3+ phosphor under VUV excitation.
Park et al. [115] reported highly efficient LnVO4:Eu3+ (Ln =Y, La, Gd) phosphors doped with Eu3+ and Bi3+ prepared by solid-state reaction.

The internal color of the inclusions is not uniform, EDS analysis showed that the inclusions were mainly a composite inclusions composed of oxides of Al, Ti, Ce and MnS, The internal inclusions were mainly the oxide of Al, Ti, Ce and MnS, which was not easy to find.
The outer inclusions were the complexes of Ti-RE-Si-Al oxides and MnS inclusions.

The analysis of phase diagrams in their recently updated form [21] for all known HTSMA systems [18-20] has shown that the binary equiatomic intermetallic compounds of the AB type (A – Ti, Zr, Hf, Nb, Ta; B –Co, Ni, Cu, Ru, Rh, Pd, Ir, Pt, Au), as it is shown in Fig. 1, represent the basis for the majority of HTSMA (except for the cobalt- and iron-based solid solutions, Cu-Al intermetallic and also Ni-Al, Ni-Mn(Ga)).

Tests with different flax fibre-reinforced biodegradable matrix polymers by Hanselka et al
George et al [126] used the XPS technique to study the surface composition of flax fibers.
Fernandes et al. [187] investigated the thermal behavior of bagasse fiber reinforced polyvinyl alcohol composites.
Recently, Boudenne et al [209,210] and Agoudjil et al [211] proposed two new periodical methods for simultaneous measurement of thermophysical and thermoradiative properties of opaque materials such as thermal conductivity, diffusivity and emissivity.
The mechanical and electrical anisotropy of pineapple fibers was investigated by Dutta et al

The ternary phase diagrams currently available are essentially based on the extensive work of Eremenko et al. dating back to 1970 and to the thermodynamic modelling of Dezellus et al. [122].

Nickel (II) oxide (NiO) nanoparticles were prepared using the method described by Xiang et al. [12] Briefly, 100 mL of precipitation solution, ammonium hydrogen carbonate was dropped at the rate of 5.0 mL min -1 into 50 mL of 0.5 M nickel (ii) ions solution.
Cobalt (II, III) oxide nanoparticles were synthesized using the method described by Yao et al. [13]6.0 g of cobalt (II) nitrate hexahydrate was dissolved in 200 mL isopropyl alcohol-water (1:1 v/v) solution in a three-necked round bottom flask. 50 mL of isopropyl alcohol-ammonium hydroxide solution was added to the solution and aged 6hours to ensure complete precipitation.
The values reported herein for Pyrene are an order of magnitude greater than those reported by Tovide 0.132 pM, on a glassy carbon electrode modified with a polyaniline-tungsten oxide- graphene nanocomposite, using cyclic voltammetry [25], but lower compared with the value reported by Rassieet.al 2011; where they used a using a gold electrode that was modified with a synthesized polythiophene dendrimer known as 2,3-di(5,5′′-dihexyl- [2,2′;3′,2′′] terthiophene5′-yl)thiophene(5) (7T.); their LoD for Anthracene and Phenenathrene was estimated to be 19 nM [77].

Echaabi et al. [7] studied the effect of the l/h ratio on the bending behavior of a quasi-isotropic unidirectional laminate.
Using the moiré technique at the free edge side, Czarnek et al. [4] and Herakovich et al. [11] studied a symmetrical laminate designated [(θn/-θn]s where n = 2 and θ = 10°,25°, 30°, 45°; they mentioned crucial displacement gradients at the +θ/-θ interface.
Hynes et al. [15] evaluated two different stacking sequences of a fiber metal laminates with carbon fiber reinforced composites.
Caminero et al. [19] observed a delamination failure under bending loading for stacking sequence with l/h=9.25.
The same result was highlighted by Caprino et al. [23].
