“…At an aluminosilicate-conjugated ampicillin concentration of 125 µg/ml, the aptamers bound to all the available target molecules caused the molecules to become saturated. Finally, the ELASA assay confirmed that the attachment of aluminosilicate with ampicillin had the ability to detect small biomolecules, complex targets and cells, suggesting potential applications in the biomedical and pharmaceutical industries 21,[46][47][48] . www.nature.com/scientificreports www.nature.com/scientificreports/ Joss paper-extracted aluminosilicate nanocomposites for use in drug-delivery.…”

“…The differences might be due to the variation in the thickness of the peptidoglycan layer of the gram-negative (E. coli) and gram-positive (B. subtilis) bacteria. Since the peptidoglycan layer in B. subtilis was thicker, the antibiotic could not penetrate the bacterial cell wall as easily as it could with E. coli due to it having a thin peptidoglycan layer 20,23,27,48 . At the highest concentration of ampicillin (0.5 µg/µL), the zone of inhibition examined against E. coli was 6.5 mm, whereas the bacterial inhibition observed against B. subtilis was 2 mm, indicating that the bacterial inhibition of ampicillin against E. coli was 3-fold higher than the inhibition shown against B. subtilis.…”

An incredible amount of joss fly ash is produced from the burning of Chinese holy joss paper; thus, an excellent method of recycling joss fly ash waste to extract aluminosilicate nanocomposites is explored. The present research aims to introduce a novel method to recycle joss fly ash through a simple and straightforward experimental procedure involving acidic and alkaline treatments. The synthesized aluminosilicate nanocomposite was characterized to justify its structural and physiochemical characteristics. A morphological analysis was performed with field-emission transmission electron microscopy, and scanning electron microscopy revealed the size of the aluminosilicate nanocomposite to be ~25 nm, while also confirming a uniformly spherical-shaped nanostructure. The elemental composition was measured by energy dispersive spectroscopy and revealed the Si to Al ratio to be 13.24 to 7.96, showing the high purity of the extracted nanocomposite. The roughness and particle distribution were analyzed using atomic force microscopy and a zeta analysis. X-ray diffraction patterns showed a synthesis of faceted and cubic aluminosilicate crystals in the nanocomposites. The presence of silica and aluminum was further proven by X-ray photoelectron spectroscopy, and the functional groups were recognized through Fourier transform infrared spectroscopy. The thermal capacity of the nanocomposite was examined by a thermogravimetric analysis. In addition, the research suggested the promising application of aluminosilicate nanocomposites as drug carriers. The above was justified by an enzyme-linked apta-sorbent assay, which claimed that the limit of the aptasensing aluminosilicateconjugated ampicillin was twofold higher than that in the absence of the nanocomposite. The drug delivery property was further justified through an antibacterial analysis against Escherichia coli (gramnegative) and Bacillus subtilis (gram-positive). An increasing amount of fly ash is being produced at an alarming rate throughout the world, and it is not a simple subject to be neglected. More than 90 million tons of fly ash are being produced annually in India, China and the USA and ~50,000 acres of land are used for ash ponds 1. Apart from coal combustion in thermal power plants, joss paper fly ash also shows a significant contribution toward tremendous fly ash accumulation. Joss paper has been used since the time of the six dynasties, and it is widely burned by the Chinese population during their festivals and funerals as a notable tradition. An estimated 90,000 to 220,000 tons of joss paper is burned each year. Although the exact figure has not been identified, it is one of the main causes of air pollution, predominantly in China and Taiwan. Efforts toward the invention of ecofriendly burning furnaces with high-efficiency incinerators, to reduce the release of heavy metals from fly ash, are not disregarded but have never met the expected objective 2,3. Several efforts have been shown for the disposal or recycling of joss fly ash. The consumption of fly ash...

We demonstrate a green chemistry approach to synthesize narrow-sized zerovalent iron (nZVI) nanoparticles using Artocarpus heterophyllus Lam. leaf extract as reducing and capping agent. The produced nZVI was characterized by various instrumental methods including ultraviolet-visible spectra, transmission electron microscopy, vibrating sample magnetometer (VSM), X-ray diffraction, and Fourier transform infrared spectroscopy. Based on the electron microscopy observations, the particle size was estimated to be ∼30 nm. In VSM, the saturation point of magnetization was observed to be 0.6 emu g −1 under a magnetic field of 0 ± 30 kOe. The synthesized nZVI was amorphous in nature as per the XRD results. The catalytic activity of the nZVI was employed for the catalytic reduction of 4-nitrophenol (4-NP) and decoloration of textile dyes such as methylene blue, methyl orange, and malachite green, respectively. The proposed nZVI synthesis method exhibited better catalytic performance toward reduction of 4-NP and degradation of dyes within 4 min for 0.1 mg of catalyst. Moreover, the synthesized catalyst nZVI can be recoverable and reutilized in many cycles without loss of its significant catalytic activity. The synthesized nZVI could be a promising material to treat industrial wastewater via profitable, sustainable, and ecofriendly approaches.

“…They are also huge sources of many bioactive substances, responsible for their diverse pharmacological actions (Joseph et al 2020;Mandavgane and Kulkarni 2020). In the past few years, several investigations have been confirmed their effectiveness, individually or in combination with herbal formulation, for the treatment of many infectious, physiological, and metabolic disorders in humans, including cancer, diabetes, hypertension, and viral diseases (Randhawa and Sharma 2015;Suk et al 2018). Recently, cow urine has been used for nanomaterial synthesis (copper, silver, and palladium nanoparticles) with numerous biomedical applications (Vinay et al 2019;Prasad et al 2020;.…”

The world population exceeded 7.8 billion people in 2020 and is predicted to reach 9.9 billion by 2050 as per the current increasing rate of 25%. In view of this, ensuring human health and food security has become an issue of key importance to countries with different degrees of economic development. At the same time, the livestock sector plays a strategic role in improving the economic, environmental, and sociocultural stewardship of any nation. The cow ( Bos indicus ) has held a distinctive role in human history ever since its domestication because of its valued harvests like dairy products (milk, clarified butter, yogurt, curd, and buttermilk) excreta like dung and urine. These products, except dung, provide all the necessary energy and nutrients to ensure the proper growth and development of the human. They are the source of many bioactive substances, which possess immense pharmacotherapeutic action against various physiological, metabolic and infectious disorders, including COVID-19. The use of urine and dung can be considered a low-cost agricultural practice for farmers and has been extensively used in modern agriculture practices to ensure food security via soil fertility, plant pathogens, and pests. Cow urine mediated synthesized nanomaterial also display distinctive characteristics and novel applications in various fields of science and technology. Thus, this paper aims to provide a comprehensive overview of cow products, describing their biochemical constituents, bioactivities, and their utilization in the area ranging from human welfare to agriculture sustainability. An attempt is also made to present possible applications in bioenergy production and pollution reduction.
