Mechanistic insights into the formation of phase pure V2O5 2D nanostructures: Advanced fourier transform-raman spectroscopy analysis Shrivathsa V S, Shounak De, Shubhava Shetty, Deekshitha K, Yuvaraj A R, Jayarama A, Shriganesh Prabhu, Richard Pinto Thin Solid Films, 2025 Vanadium Pentoxide (V₂O₅) thin films and 2-Dimensional nanostructures have gained significant attention for their unique properties and diverse applications in gas sensing, energy storage, catalysis, and electrochromic devices. Despite their potential, a comprehensive understanding of their growth dynamics remains limited. This study offers a detailed exploration of the synthesis and properties of phase-pure V₂O₅ thin films and their nanostructures using a combination of solution combustion synthesis and spray pyrolysis deposition. The Aqueous Combustion Mixtures (ACM) were prepared using ammonium metavanadate and urea as precursor solutions, which were used to deposit V 2 O 5 using the spray pyrolysis technique at temperatures ranging from 200°C to 550°C. Advanced characterization techniques, including Field Emission Scanning Electron Microscopy, X-Ray Diffraction, and Fourier Transform Raman Spectroscopy, were employed to analyze the films. The results revealed that films synthesized at 400°C exhibited exceptional crystallinity, microstructural integrity, and phase purity. At higher temperatures, a meta-stable β-V₂O₅ phase was also observed. This research bridges a critical gap in the existing literature by enhancing the understanding of the growth mechanisms of V₂O₅ thin films and their nanostructures, thereby facilitating the optimized formation of high-quality V₂O₅ nanostructures for advanced technological applications.
Bio gas production from blends of canna generalis plant chaff with cow dung and poultry waste Pushparaj A. Naik, K Deekshitha, M Janakaraj Iop Conference Series Earth and Environmental Science, 2024 Canna x generalis plant is proved as a wetland species identified for the treatment of partially treated domestic wastewater. Mycrophyte chaff harvested from wetland system is commonly discharged into the environment, posing a hazard to the friendliness of the environment. There are examples of plant chaff being used as a renewable energy source, particularly in the production of bio gas. Therefore a study on the biogas production from blends of canna x generalis plant chaff with cow dung and Poultry waste is carried out. The wastes are blended as Canna chaff and Cow dung (CC: CD), Canna chaff and Poultry dropping (CC: PD), all in different ratios, while the CC alone served as control. The CC waste is ground, blended with cow dung and Poultry waste and charged to the digesters in the prescribed ratio. The moisture content of the wastes are determined as the water to waste ratio. The anaerobic digestion is operated under a mesophilic temperature range of 23°C - 37°C during the digestion period. Findings revealed that the cumulative biogas yield from cow dung and canna chaff in 1:3 and 1:4 ratios is 40 % higher than the cumulative biogas yield from canna chaff alone. The cumulative biogas produced by combining Poultry droppings and canna chaff in a 1:3 ratio is 32 percent more than the cumulative biogas yield with substrate canna chaff alone. All the blends commenced flammable gas production within 24 hr of charging the digesters, however, the gas flammability was not sustained and gas production decreased considerably after 4th day. Overall results show that blending the canna plant chaff with cow dung and Poultry droppings in proportion 1:3 yielded maximum cumulative biogas over the entire digestion period.
