Solid State Reaction Synthesis and Characterization of Aluminum Doped Titanium Dioxide Nanomaterials

“…This type of material has a direct optical band gap of about (3.3-3.44) eV at an ambient temperature within II-IV semiconductor groups, and a high absorption coefficient with a low cost. Al:TiO 2 (ATO) nanomaterials has been used in various applications., for example, gas sensing [18], antibacterial activity [19], perovskite solar cell [20], energy conversion, and storage applications [21]. For more applications of Transparent conductive oxides (TCO) materials in applied mathematics, Boubaker polynomials can be used to investigate the properties of these materials [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32].…”

Performance of hybrid nanostructured conductive cotton threads as LPG sensor at ambient temperature: preparation and analysis

“…This addition of electrons into the conduction band of the sensing surface on threads is a result of decreases in resistance of the sensor. 13,19 As was discussed earlier 1 PAni/g-Fe 2 O 3 nanostructures show a high sensing response to LPG gas due to the presence of the adsorption centre of Fe(III). Moreover, high dispersity of PAni/g-Fe 2 O 3 nanostructures on the conductive threads provides efficient electron exchange between the cations: Fe(III) 4 Fe(II).…”

“…To overcome these draw backs, conducting polymers (CPs) and nanostructures (such as nanoparticles, nanotubes, nanosheets, nanoowers and nanowalls) have been recently investigated as effective materials for room temperature chemical sensors which have favorable properties such as easy processability and degree of miniaturization. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Sensing technology [21][22][23][24][25][26] has become more signicant because of the various sensing methods (based on different materials and techniques) and their widespread smart wearable applications. Xiao et al 22 summarized a comparison of various sensing materials and methods, along with their performance, advantages and disadvantages.…”
