Fabrication of Spherical Porous pAg 2O-nWO 3/Ag/GNS Heterostructure with Enhanced Photocatalytic Activity Through Plasmonic S-Scheme Mechanism and its Complementing Biological Interest

SSRN Electronic Journal (2021)

Abhilash Mavinakere Ramesh Miss. Anju Kodandaram Chandrakantha Kampalapura Swamy Akshatha Gangadhar N. Chandra Mohana

The synthesis and characterization of Ag2OWO3/Ag/GNS heterostructure with desired modifications has been elucidated in the contemporary study. The fabrication involves a simple hydrothermal method for the configuration of fascinating heterostructures intended to photo-catalytically degrade Eosin Yellow (EY) dye. The toxic dye molecules were converted into non-toxic molecular intermediates, also the elimination of heavy metals from industrial wastewater, being trapped in the pores of heterostructure. The pn junction photocatalyst with plasmonic resonance of Ag for abolition of electron and hole coupling, enhances the photo-response where the catalyst abides S-Scheme mechanism. The work functions of active photocatalysts as calculated for Ag2O is 6.61eV and WO3 is 6.04eV. Furthermore, the Ag2OWO3/Ag/GNS photocatalysts recovery and re-use in several trials without any noticeable loss of photocatalytic activity, complimented the recyclability of the heterostructure. To ensure the safety of the environment on heterostructure being released, toxicity analysis were carried out. These Ag2OWO3/Ag/GNS heterostructures had optimistic result on cytotoxicity assay, and on Musmusculus skin melanoma cells (B16-F10), with anti-microbial/fungal properties. Thereby, the contemporary experiment upholds efficient photocatalysis and ropes multiple errands on biological applications.

Sustainable production of graphene oxide with ascorbic acid reduction: characterization and insights

International Journal of Nanoelectronics and Materials (IJNeaM) (2024)

T. J. Lee Chun Hui Tan N. Chandra Mohana Hing Wah Lee Chun Hong Voon

In this study, graphene oxide (GO) was synthesized from graphite powder using KMnO4 and a concentrated mixture of H2SO4/H3PO4. The obtained GO was subsequently reduced using ascorbic acid. The ratios of H2SO4 to H3PO4 and KMnO4 to graphite powder were kept constant. The synthesized GO and reduced graphene oxide (rGO) were evaluated using UV-visible spectroscopy, FT-IR spectroscopy, XRD, SEM, and EDX. The findings showed that processing graphite powder with KMnO4 at 60 °C for 12 hours resulted in a high degree of oxidation and minimal defects. Furthermore, ascorbic acid, an alternative to highly toxic hydrazine, aided in eliminating oxygen-containing functional groups in the rGO. This study focuses on the properties of GO produced using the improved Hummer's method, and the changes observed after chemical reduction.

Preparation of Feed and Characterization of Feed Supplemented with Phytocompounds

Springer protocols handbooks/Springer protocols (2023)

N. Chandra Mohana A. M. Nethravathi Raghu Ram Achar K. M. Anil Kumar Jalahalli M. Siddesha

Aquaculture has gained prominence globally in recent years particularly in fish and shrimp production. The increased surge of demand has led to a rapid increase in several aquaculture setup implementations. However, it also has raised the risks of disease outbreaks leading to mass mortality rates caused by bacteria, viruses, and fungi. Also, inappropriate use of antibiotics leading to resistance in microbial pathogens is an expanding threat. Hence, feed preparation and characterization using ethnomedicinal plants could offer relief for the present requisite in aquaculture. Feed formulation by analyzing nutritional needs supplemented with ethnomedicinal plant-based feeds would benefit aquaculture in encountering antibiotic resistance. The feed formulation using plant-based feeds would envision natural solutions for infections along with economical sustainability with low-cost feed for the growing aquaculture industry.

Amylase Production by Solid State Fermentation of Agro-industrial Wastes Using Bacillus species

European Journal of Nutrition & Food Safety (2019)

N. Chandra Mohana Onyemaechi Okezie A. N. Ezugwu

This study evaluated amylase production by Bacillus species employing the solid state fermentation (SSF) method using five agro-industrial wastes namely corn cobs, potato peel and maize straw, groundnut husk and corn chaff. Five Bacillus species were tested for amylase production abilities and Bacillus subtilis showed the highest amylase production ability after incubation. Corn chaff gave maximum enzyme production (3.25 U/ml) while the least enzyme was recorded on groundnut husk (2.35 U/ml) at 25. Potato peel had maximum enzyme production by Bacillus subtilis (3.05 U/ml) at pH 7.0 while the least enzyme production was from groundnut husk (2.84 U/ml) at pH 4.0.Thus there was an increase in enzyme production with corresponding increase in substrate concentration. The results obtained in this study support the suitability of using agro-industrial wastes as solid state fermentation substrates for high production of amylase. It’s also a means of solving pollution problems thus making solid state fermentation an attractive method.

Biosynthesis of ZnO-NPs from mycoendophyte Alternaria alternata

Inorganic and Nano-Metal Chemistry (2024)

Narendra Kumar H.K.N. Chandra Mohana Abhilash M.R Chandra Nayaka S S. Satish

Fungi-mediated biosynthesis of nanoparticles is a potentially beneficial strategy for large-scale production. In this study, ZnO-NPs were synthesized biogenically using a cell free broth from mycoendophyte Alternaria alternata inhabiting Piper cubeba as a reducer and stabilizer agent. ZnO-NPs appeared to be spherical in transmission electron microscopy, Histogram reveals the nanoparticle size between 20 and 60 nm, and FTIR experiments were employed to analyze the structure, shape, and physicochemical characteristics of the ZnO-NPs. The biosynthesized nanoparticles exhibited an absorption peak at 346 nm in the UV–visible spectrum, which corresponded to the plasmon resonance of ZnO-NPs. The X-ray diffraction spectra of the nanoparticles revealed the formation of crystal planes and hexagonal crystal geometry metal oxides of zinc. In experiments, biosynthesised ZnO-NPs were proven to be exhibit broad spectrum antimicrobial activity. Based on antimicrobial studies bacteria were found to be more susceptible when compare to fungi exhibiting antibacterial activity equal that of co-assayed standard (18–21 mm zone of inhibition). As a result, ZnO-NPs could be mass-produced sustainably, with the potential to be used in a range of biological processes.
