Selective doping of TiO2 with elements such as Fe [9], Co [10], Al [11], W [12] and other elements might enable it to achieve better electrical and optical properties for their practical applications.
Similar study has been reported for Al:TiO2 in literature [11].
Mechiakh et al. [21] have reported the absence of the TM modes in the thin films TiO2 prepared by the sol-gel process from the tetrabutyl orthotitanate solution as precursor.
However, Mugnier et al. [22] have obtained single-mode waveguides in TE and TM from a single layer of TiO2 and multimode from multilayer (4 layers) TiO2.

This is consistent with the results of Perfus-Barbech et al. [18].
For example, Salt et al. [19] found that contents of Cd in leaves of B. juncea treated with ABA decreased rapidly, so they suggested that Cd accumulation in leaves depend on the transpiration.

Compstonet al.[10] has investigated the relationship between the interlaminar fracture toughness of composite and the toughness of VE matrix modified by rubber.Stevanovic et al. [11] found that delamination resistance of mode I and mode II fracture toughness test increased with the addition of poly(acrylonitrile-butadiene-styrene) (ABS) blends into VE resin to form a interlayer.
Chen et al. [12] found that both thetensile strength and interlaminar shear strength of composite increased when carbon nanotubes were incorporated into VE resin.Liang et al. [13] also improved the interfacial strength by the modification of VE resin matrix with polypropylene (PP) fiber.
b a Fig.5 Low magnification SEM images of the fractured surface of CF/VE composites at the crack propagation area: (a) conventional VE, (b) AC According to Hine el al’s theory [15], the total GIC can be described by some individual contribution, GTOT=GM+GBK+GP+GDEB Where the total fracture toughness (GTOT) consisted of energy involved matrix deformation (GM), fiber breakage (GBK), fiber pull-out (GP) and interfacial debonding (GDEB).
