Electrospun Polymer Nanofibers in Catalysis for Pollutant Removal Madhavi Konni, Manoj Kumar Karnena Polymer Nanocomposites Fabrication to Applications, 2023 Electrospun nanofiber-related materials have recently gained much prominence in catalysis applications. The electrospun materials are reliable, and preparation methods are more straightforward than the conventional materials used for catalysis. The catalysis application for the degradation of pollutants with high-effective rates attracted scientists worldwide to develop state-of-the-art catalysts to remove the contaminants from the environment to be sustainable. Even though several studies are available in the literature, there is still a need for novel preparation methods to synthesize nanofibers. Further, the researchers are continuously working on the current topic and found that few electrospun nanofibers are efficient for the remediation of contaminants in a sustainable manner. Along these lines, the current chapter discusses the introduction to electrospun nanomaterials, a brief timeline of the electrospun nanofibers, preparation, catalyst types, and various catalysts produced by the researchers using electrospinning techniques and their utilization to degrade the organic and inorganic dyes and future challenges of the electrospun nanofibers.
A proposed Fuzzy logic model for Electrospun nanofiber pressurised membranes for water treatment-A review A.Ganapathi Rao, V.Pavan Kumari, Manoj Kumar Karnena Journal of Applied and Natural Science, 2023 Electrospun nanofiber membranes and nanocomposites for water treatment is an emerging concept growing faster in science, gaining more prominence among various scientists, and creating attention to improve water quality. The familiarity with fabricating these materials is increased, and researchers worldwide target more nanomaterial manufacturing and synthesis for several applications. The electrospinning process for nanofibers' preparation allows polymers to incorporate various functionalized materials. Scientists have recently proposed electrospun membranes using fluorinated compounds and polymers with hydrocarbons. The membranes prepared by the electrospun nanofiber to purify water created a primary research axis, and various laboratory experiments proved efficient. In recent years, the usage of fuzzy analysis in industries has increased, and these logics are applied in every unit process of the water industry. The present review primarily discusses the recent pressurized electrospun membrane technologies utilized in the water industries and machine learning methods that can be applied in the water industries. Further, it suggests a new novel way of integrating options to connect the fuzzy with water treatment to enhance the electrospun nanofiber prospects in the water industry. Implementing these fuzzy models in future by water industries might reduce maintenance costs and help in understanding the characteristics of the effluent quality in detail.
Sustainable Recent Development Practices for the Plastic Waste Management: A Review Madhavi Konni, Bhavya Kavitha Dwarapureddi, Manoj Kumar Karnena Waste Recovery and Management an Approach Toward Sustainable Development Goals, 2023 In recent years, plastic waste has created a menace to the milieu and public health. Plastic waste treatment methods like incineration and landfilling can’t efficiently treat plastic waste. Thus, there is a need for advanced treatment units to reduce and manage plastic waste generated by anthropogenic activities. Plastic waste treatment has become the sustainable development goal by 2025. The current book chapter reports the sustainable plastic waste treatment technologies from the literature available and analyses the mechanisms; it proposes solutions to reduce the gaps between recent developments and industrial requirements. The technologies presented in the chapter are categorized based on plastic recycling and plastic degradation. The recycling methods of non-biodegradable plastics were divided into recycling, reuse, and recovery of resources. The plastic degradation methods were divided into oxic and anoxic biodegradation. Further, the current chapter aims to provide insights within a detailed introduction to the advanced treatment technologies for plastic treatment, enabling us to understand the status of the emergent technologies in treating plastic waste, other sustainable technologies like biodegradation, composting, etc., available for treatment, and the future scope of research to develop novel technologies was discussed.
Sustainable Nano-Bioremediation Approaches for the Treatment of Polluted Soils Irrinki Hemalatha, Dakamari Harika, Manoj Kumar Karnena Nature Environment and Pollution Technology, 2022 Due to the widespread adoption of conventional approaches for the remediation of contaminated soils, these techniques have become more well-known in the literature. However, these methods have both advantages and disadvantages. Integrating traditional degradation technologies with Nano-technology might be the right solution for removing toxicants from the environment to overcome these problems. Nano bioremediation is a new technique that has gained prominence in recent years among many researchers worldwide. These techniques aim to remove the contaminants’ concentration and minimize their impacts on the environment. The integrated approaches benefit bioremediation and nanotechnology to remove the pollutants more efficiently within less time in an eco-friendly manner than individual processes. The current review provides insights into nanotechnology and different kinds of nanomaterials that have been reported in eliminating pollutants from the environment. Further, the mechanism and challenges with nano bioremediation were explained in detail.
Contemplations and investigations on green coagulants in treatment of surface water: a critical review Manoj Kumar Karnena, Vara Saritha Applied Water Science, 2022 Coagulation is an essential and easy process to treat water and wastewater and also to adopt for point of use solutions. Coagulants have played a significant role in providing safe and potable water. Nevertheless, the ill effects of chemical coagulants, such as health effects and substantial sludge quantities, cannot be ignored. Under given conditions, the search for alternative coagulants has been the need of the hour, and researchers have presented those natural coagulants are promising alternatives. The exploration and evaluation of plant-based coagulants have shown that these are fit to substitute chemical coagulants sustainably. Previous studies have presented the efficacy of various coagulants but could not fill in the gap existing in terms of a cumulative database of natural coagulants. In these lines, the focus of the current review is to present the history of natural coagulants, the science involved and studies carried out to evaluate them at different levels. Furthermore, a cumulative database of 57 natural coagulants with their efficacy in removing impurities from raw water is presented.
Sustainable current waste management practices and approaches in the construction industry of India Madhavi Konni, Madhuri Pulavarthi, Manoj Kumar Karnena Clean Technologies and Sustainable Development in Civil Engineering, 2022 Developing countries like India are adopting new construction techniques for waste minimisation and practices due to the stringent rules and regulations from the past few years. However, some construction industries continuously fail to adopt and understand the legislation to minimise the limited use of natural resources. Recycling the construction waste during the construction phases is the new method currently adopted by the construction industries to reduce the waste. The current review attempts to identify the list of the techniques available for the minimization of waste in construction. Further, the authors have listed the various sources of waste generation in the construction industries and how the countries deal with the current waste.
