Investigations on the electronic properties and effect of chitosan capping on the structural and optical properties of zinc aluminate quantum dots

Novel gamma-irradiated chitosan-doped reduced graphene-CuInS2 composites as counter electrodes for dye-sensitized solar cells

“…The broad peak at approximately 22.15° indicates an amorphous structure of chitosan. 20 The peaks corresponding to CuInS 2 appeared at 29.1°, 31.4°, 1–32 42.5°, and 49.1° for the planes (112), (200), (204), and (312), respectively. This indicated the complete conversion of In 2 S 3 into CuInS 2 .…”

“…It has been reported that the solubility, growth-promoting properties, and electrical properties of low-Mw chitosan are substantially better than those of high-Mw chitosan. 11 Normally, chitosan can be degraded under conditions of acidic and alkaline hydrolysis. It can also be degraded under conditions of enzymatic treatment.…”

Investigation of Transition Metal Ions Cu2+ and Mg2+ Doped Zinc Aluminate (ZnAl2O4) and Their Structural, Spectral, Optical, and Dielectric Study for High-Frequency Applications

“…From Figure 4, by plotting (F(R)hν) 2 against hν and bringing the straight-line region of the curve to the x-axis (αhν) 2 = 0, the energy gap of the material can be calculated as shown in the figure. The optical band gap value is evaluated to be 3.03 eV, 2.94 eV, and 2.90 eV for ZA, ZAC, and ZAM samples obtained from the Kubelka-Munk plot.…”

“…Copper Cu 2+and Magnesium Mg 2+ -doped zinc aluminate have a spinel crystal structure, with copper ions (Cu 2+ ) and magnesium ions (Mg 2+ ) substituted for some of the zinc ions (Zn 2+ ) in the lattice. The material's dielectric behavior, such as its dielectric constant and tangent loss, can be affected by exact doping levels of copper and magnesium, which are important for electronic applications [2]. The material's high thermal stability and resistance to moisture and humidity also make it suitable for use in harsh environments [3].…”

One-pot synthesis of iron oxide - Gamma irradiated chitosan modified SBA-15 mesoporous silica for effective methylene blue dye removal

“…Under the influence of an electron or γ-ray beam, chitosan breaks down into little pieces. Low molecular weight chitosan has reportedly been found to have significantly greater solubility, growth-promoting characteristics, and electrical properties than high molecular weight chitosan [ 25 ]. γ-Irradiated chitosan is used by Mirajkar et al to deploy γ-irradiated chitosan–silver nanocomposites for the control of phytopathogens and to research the antibacterial activity of IR–CSN–Ag NPs [ 24 ].…”
