For example, Matijevic et al. [6] prepared uniform
spherical rutile particles by forced hydrolysis of Ti(IV) ion at 98°C in highly acidic media in the
presence of sulfate ion.
The anatase phase was al so found to be involved with increasing sulfate concentration.
Barringer and Bowen [7] and Ogihara et al. [8, 9] prepared uniform amorphous titania speres on the order of submicrometers by the hydrolysis of titanium tetraethoxide in ethanol or a mixed solvent of acetonitrile and octanol in sol-gel systems.

The concept was extended to describe the impact of local plasticity and geometrical nonlinearities on the response of structures by Kasahara et. al. [2,3].
Recently Aird et. al. [4], Hadidi-Moud and Smith [5] and Smith et. al. [6] used benchmark model structures and performed experimental studies that illustrated the dependence of EFU on the relative stiffness of structural components.

Reddy Annapu et.al. reported that the enhanced magnetic properties can be strongly correlated with particle size due to modification in the long range cycloid spin structure [11].
Nurhidayati M et.al. reported that the magnetic properties of bonded magnet BaFe12O19 with natural rubber as binders are influenced both on the filler content and compositions of binder [12].
Monica A G et.al. reported that the tensile strength of bonded magnet made from melt spun powder increases with increasing volume fraction of magnetic powder [7].

The sugarcane bagasse fiber, here denoted as bagasse fiber for short, presents the physical and structural characteristics shown in Table 1 from the work of Satyanarayana et al. [19].
Adapted from Satyanarayana et al [19] α –Cellulose [%] Hemi-Cellulose [%] Lignin [%] Cell Length [mm] Crystalli-nity [%] Density [g/cm³] Elastic Modulus [GPa] Ultimate Tensile Strength [MPa] Total Strain [%] 54.3-55.2 18.8-29.7 25.3-24.3 0.8–2.8 47 0.45-0.49 27.1 222 1.1 Experimental Procedure The materials used in this investigation were a relatively long bagasse fiber, obtained from roll-pressed sugarcane stalks after all juice has been extracted, as well as a diglycidyl ether of the bisphenol–A (DGEBA) epoxy resin with 187.3 g/equiv.

According to Umer et al. [15] stated that metal compounds usually reduce into their respective nanoparticles because of microbial enzymes or the plant phytochemicals with antioxidant or reducing properties.
Screening of palm leaves extract performed by Samim et al. [13] revealed the presence of tannins, alkaloids, reducing sugarsm steroid, saponins, terpenoid, and flavonoids.
The time length for control experiment was conducted for 4 hours according to Dang et al. 2011 [4] to ensure the fully reaction was occurred.

The alloying element Al stabilized the α phase while the V stabilized the β phase [6].
Pilehva et al. [5] conducted solution treatment at temperatures 850, 900, 950ºC, and showed that the microstructure was dominated by the α phase (equiaxed and lamellar α), and the volume fraction of β phase increased with temperature.

However, the high reactivity of silicon with the different compounds frequently used for the growth of
nitrides (Ga, Al, H2, NH3…) makes the substrate preparation and the nucleation more delicate [6] than
on a substrate like SiC, and GaN on Si suffers from a risk of crack generation due to the tensile stress
induced by the large lattice mismatch (17%) and the thermal expansion coefficient difference (55%)
between GaN and Si.
The integration of the capacitance from pinch-off up to 0V shows sheet carrier densities in agreement with expected values for the considered aluminum contents in the barrier, i.e., 7x10 12 cm-2 and 1.1x1013 cm-2 for Al molar fractions of 25 and 29% respectively.
For comparison, structures grown on bulk Si(111) with an Al molar fraction of 28% exhibit a carrier density of 8x10 12 cm-2 and electron mobility varying between 1590 and 1890 cm²/V.s. 1.E+13 1.E+14 1.E+15 1.E+16 1.E+17 1.E+18 1.E+19 1.E+20 1.E+21 0.0 1.0 2.0 depth (µm) N (cm-3) 1KHZ 100KHZ 2DEG GaN Conclusion In summary, GaN based HEMT heterostructures have been grown on Si(111) with intermediate 3C-SiC layers.
