New ternary compounds stoichiometry-linked thermal behavior optimisation using Boubaker polynomials

Some physical investigations on ZnS1−xSex films obtained by selenization of ZnS sprayed films using the Boubaker polynomials expansion scheme

“…8). As it was noticed [19,24] that the slope S 0 (Eq. (6)) is proportional to the slope of the curve a=f (l) for high values of the incident energy (low values of l), and according to the close values yielded by (Eq.…”

“…8) of n measured values of the absorption coefficient and wavelength: (a i , l i ) i = 1..n , in order to establish a practical and exploitable correlation. Since the two variable ranges were different (10 5 -10 6 for the absorption coefficient and 10 À 7 -10 À 6 for the wavelength); we chose the Boubaker polynomials [21][22][23][24][25] expansion (eq. 7) as a pondered convergent [21] sum…”

Pure and zirconium-doped manganese(II,III) oxide: Investigations on structural and conduction-related properties within the Lattice Compatibility Theory scope

“…Consecutively, and under similar experimental conditions, Zirconium-doped Mn 3 O 4 :Zr thin films solution have been fabricated by adding hydrated Zirconium chlorine hexahydrate (ZrCl 2 (6H 2 O), 99.9% purity) to the precursor solution while maintaining acidity level [20][21][22][23]. In the different elaborated samples, the 1-3%.…”

“…These investigations were based on the "Mirage Effect" protocol [17][18][19][20], which is detailed later, and yielded interesting values of thermal conductivity and diffusivity. Finally, optical measurements, in the UV-Visible range were carried out using a Schimadzu UV 3100 double-beam spectrophotometer, within a (300-1800 nm) wavelength range.…”

Flowerlike cubic β-In2S3 microspheres: Synthesis and characterization

“…Among these, ␤-In 2 S 3 is a typical n-type semiconductor with a band gap of 2.0-2.2 eV. Owing to its unique catalytic, optical, electronic and gas-sensing properties, it can be used as catalysts, luminophors, solar cell devices, optoelectronic, and acoustic industries [2][3][4][5][6]. It is well known that the size, shape and dimensionality strongly affect the properties of nanomaterials.…”
