Rapid growth in industrialization sectors, the wastewater treatment plants become exhausted and potentially not able to give desirable discharge standards. Many industries discharge the untreated effluent into the water bodies which affects the aquatic diversity and human health. The effective disposal of industrial effluents thus has been an imperative requirement. For decades nanocellulose based materials gained immense attraction towards application in wastewater remediation and emerged out as a new biobased nanomaterial. It is light weighted, cost effective, mechanically strong and easily available. Large surface area, versatile surface functionality, biodegradability, high aspect ratio etc., make them suitable candidate in this field. Majorly cellulose based nanomaterials are used in the form of cellulose nanocrystals (CNCs), cellulose nanofibers (CNFs), or bacterial nanocellulose (BNC). This review specifically describes about a variety of extraction methods to produced nanocellulose and also discusses the modification of nanocellulose by adding functionalities in its surface chemistry. We majorly focus on the utilization of nanocellulose based materials in water remediation for the removal of different contaminants such as dyes, heavy metals, oil, microbial colony etc. This review mainly emphasizes in ray of hope towards nanocellulose materials to achieve more advancement in the water remediation fields.

This research assesses heavy metal contamination within the riparian zone of the Danro River, a tributary of the Ganges River basin in India, particularly impacted by sand mining activities. The study conducted analyses on major and trace elements in soil samples, focusing on those identified as ecologically hazardous by the Water Framework Directive of India. Utilizing a combination of indices (Enrichment Factor, Pollution Load Index, and Index of geo-accumulation) and statistical techniques such as Principal Component Analysis (PCA), the investigation aimed to evaluate contamination severity, ecological risks, and pollution sources.

Background: The widespread selective pressure of antibiotics in the environment has led to the propagation of antibiotic resistance genes (ARGs). However, the mechanisms by which microbes balance population growth with the enrichment of ARGs remain poorly understood. To address this, we employed microcosm cultivation at different antibiotic (i.

Development of bio-supported photocatalysts has become a pressing need in the field of environmental remediation. This work reports the synthesis of bio-enzyme (from banana peels) inherited (ZnO/g-CN) nanocomposite by simple soft chemical method and its photocatalytic degradation ability against the mixed dye (Methylene blue (MB) + Rhodamine-B (RhB)) under UV irradiation. Synthesized nanoparticles were characterized using experimental techniques XRD, FESEM, TEM, EDAX, XPS, UV-vis-NIR spectroscopy and FTIR.

Emerging single-atom materials and metal sulfides hold significant promise as alternatives to precious metal catalysts for nitroaromatics conversion; however, their intrinsic activity and durability remain insufficiently understood. Herein, sulfur and nitrogen co-doped carbon matrices incorporating CoS nanoparticles and single-atom Co with Co-N-S coordination were constructed through a facile pyrolysis approach. Advanced characterization techniques, such as X-ray absorption fine structure (XAFS) and aberration-corrected electron microscopy, unveiled unique structural features underpinning exceptional catalytic efficiency and recyclability.
