Herein, natural green and red dyes have been extracted from Malabar spinach (Basella alba) (Amaranthus dubius), respectively, were used as a sensitizer source for TiO2 photoanode based dye sensitized solar cell (DSSC). The efficiency of the developed DSSC with single individual obtained, 0.466% 0.531%, respectively. To improve dye-based DSSC, combined at 5 different volume ratios, to find optimum combination dyes. From UV–Vis absorption spectrum, showed cumulative properties both...
In this study, we have synthesized pristine and [0.5,1.5, 2.5] M% samarium (Sm)-incorporating α-MoO
Abstract Efficiency of dye-sensitized solar cell (DSSC) depends on several interrelated factors such as type and concentration dye, thickness photoelectrode counter electrode. Optimized combination these leads to a more efficient cell. This paper presents the effect parameters efficiency. TiO 2 nanoporous thin films different thicknesses (5 μm 25 μm) were fabricated indium doped tin oxide (ITO) coated glass by doctor blading method characterized inverted microscope, stylus surface profiler...
Abstract High energy external gamma radiation has always an impact on semiconductor material by altering its physico-chemical properties. In this paper, the effect of gamma-radiation is observed sol-gel synthesized metastable h-MoO 3 nanorods with absorbed dose variation. The irradiated sample shows a remarkable change in their structural parameters such as average crystallite size decreased, strain, and dislocation density increased so are confirmed from x-ray diffraction (XRD). Functional...
The chlorpyrifos-mineralizing rice root endophyte Enterobacter sp. HSTU-ASh6 strain was identified, which enormously enhanced the growth of tomato plant under epiphytic conditions. solubilizes phosphate and grew in nitrogen-free Jensen’s medium. It secreted indole acetic acid (IAA; 4.8 mg/mL) ACC deaminase (0.0076 μg/mL/h) hydrolyzed chlorpyrifos phosphodiester bonds into 3,5,6-trichloro-2-pyridinol diethyl methyl-monophosphate, confirmed by Gas Chromatography – Tandem Mass Spectrometry...
Synthesis of hydrogels from aqueous solution poly(vinyl alcohol) (PVA) and kappa-carrageenan (KC) has been performed with radiation processing technology using Co-60 gamma source. As investigation on the influence dose concentration KC gel content, swelling properties, thermal behaviors hydrogel performed. Gel content obtains a maximum value at 25 kGy dose. Equilibrium water decreases increased but it increases KC. The absorption is fast up to 5 hours becomes 24 hours. It in feed solution....
Abstract In this article, pure and Fe-doped (5 wt.%) α -MoO 3 nanosheets have been synthesized by hydrothermal approach doped were further annealed (at T a = 600 °C 700 temperatures for hrs) improved crystalline properties. The XRD analysis revealed the formation of orthorhombic structure without tracing impurities or secondary phases. iron dopant annealing crystallinity as crystallite size increased. pristine sample consists with randomly oriented an average width 100–200 nm length several...
