Item A Critical Review of Fabrication Strategies, Separation Techniques, Challenges, and Future Prospects for the Hydrogen Separation Membrane(Taylor and Francis Ltd., 2024) Kudapa V.K.; Paliyal P.S.; Mondal A.; Mondal S.Fossil fuels provide over 80% of the world�s current energy demand, which results in the release of large amounts of greenhouse gases (GHGs). In contrast to the emissions of GHGs caused by the combustion of fossil fuels, hydrogen combustion produces only water as a waste product. Hydrogen is a more environmentally friendly alternative fuel. The production of hydrogen energy has the potential to address energy security issues such as climate change and air pollution. There is an increasing global interest in hydrogen, particularly green hydrogen, which is produced by electrolyzing water using power derived from renewable resources. Because of falling hydrogen prices and the growing urgency of decarbonization, global demand for hydrogen, headed by the transportation and industrial sectors, might increase by about 400% by 2050. Furthermore, using environmentally friendly hydrogen will result in a reduction of 3.6 gigatonnes of total carbon dioxide emissions between 2020 and 2050. Hydrogen has the highest energy density of any known fuel, and it is widely available in enormous quantities all over the planet. It is possible that by 2050, India�s need for hydrogen will have increased by a factor of 4, accounting for more than 10% of global consumption. Steel and heavy-duty transportation are expected to account for more than 52% of overall demand growth between now and 2050. The overall market value for environmentally friendly hydrogen in India might reach $8 billion by 2030 and $340 billion by 2050. Because India�s capacity to create power from renewable sources is growing all the time, the country now can produce hydrogen from ecologically beneficial sources such as solar and wind when demand is low. Physical adsorption and polymer membranes can be employed to extract hydrogen from crude hydrogen polluted with hydrocarbons. This can be done to clean the crude hydrogen. The purity of hydrogen is an important aspect in determining whether it can be used in the energy production process. Unlike other types of separation technologies, membrane processes can be used in both mobile and small-scale applications. The membrane may function properly under a wide range of pressure and temperature extremes. The fundamental objective and goal of the separation membrane is to be used in membrane reactors for synchronous hydrogen production and purification. Other competing methods, such as pressure swing adsorption and cryogenic distillation, do not compare favorably to the membrane separation approach at lower operating temperatures. This is because membrane separation takes fewer resources than other competing technologies, particularly ones that have been around for a longer time. This article discusses the various membranes that can be used for substance separation, how hydrogen separation membranes can be made using a variety of technologies, the challenges that are inherent in doing so, and the prospects for the future, particularly in terms of increasing the efficiency of hydrogen separation. � 2024 American Nuclear Society.Item Analyzing the interconnected dynamics of domestic biofuel burning in India: unravelling VOC emissions, surface-ozone formation, diagnostic ratios, and source identification(Royal Society of Chemistry, 2024) Mondal A.; Mondal S.; Ghosh P.; Das P.Burning biomass fuels in Indian households is a common and cost-efficient way to generate energy for various domestic tasks. However, this practice is a significant source of non-methane volatile organic compounds (NMVOCs) released into the atmosphere, impacting local and global air quality. The substantial quantities of NMVOCs produced from burning biofuels at home can have adverse effects on climate and human health worldwide. This review focuses on exploring the processes involved in domestic biofuel combustion, detailing different stages of burning, and discussing the tools and techniques required to measure NMVOC emissions accurately. It also aims to identify potential emission sources through methods such as diagnostic ratios and PCA analysis. By striving to reduce NMVOC emissions from household biofuel burning, the goal is to provide a basis for informing policymakers in developing effective regulations and policies to address this environmental issue. � 2024 RSC.Item Enhancing service excellence in the hospitality industry through effective service recovery from failures(IGI Global, 2024) Singh S.V.; Ancheary T.; Mondal A.; Rajauria S.The hotel sector is a fiercely competitive and continuously expanding industry with a multitude of dif�ficulties and prospects.

All rights reserved.Item Impact and potential of carbon sequestration and utilization: fundamentals and recent developments(Taylor and Francis Ltd., 2024) Mondal A.; Gupta S.K.; Yaduvanshi S.; Khan M.; Layek S.; Kudapa V.K.; Mondal S.Carbon dioxide is a primary greenhouse gas that plays a vital role in shaping life on Earth. However, the continuous anthropogenic emissions of CO2 at prominent levels have caused severe damage to the earth as they increase the global average temperature of the earth, causing global warming. To restrict the further rise in global temperature, it is necessary to capture anthropogenic CO2 emissions efficiently by various means. Technological carbon sequestration would benefit the manufacturing industry by minimizing carbon emissions and saving on carbon taxes. This review article would explore various methods to capture carbon efficiently by improving carbon storage technology, using captured carbon economically in industries, and making fuel from captured carbon. Cooling towers can be used to capture carbon through the direct air capture (DAC) method and can be integrated with Natural Draft Dry Cooling Tower systems (NDDCTs) to lower the power consumption requirements and thus the operational costs. The captured carbon is used to make fuel by employing solid carbon directly as both an anode and fuel, with 80% higher efficiency than solid oxide fuel cells. It also emits fewer pollutants than typical coal-burning power plants. � 2024 Taylor & Francis Group, LLC.Item India's shift toward sustainable energy: A comprehensive approach to renewable energy integration and environmental sustainability(American Institute of Physics, 2024) Mondal S.; Mondal A.; Rathore J.; Koundinya K.K.; Sharma A.K.India's reliance on coal for energy has led to pollution, carbon emissions, and environmental hazards.

Breakthroughs in recent years have made it possible to design effective carbon capture and safe spaces for its storage. A comprehensive worldwide case studies are presented for both successful CCS project implementation and their environmental impact assessment. Lessons learned from these case examples are reflected through the challenges and policy hurdles with its impact on the global economy. An outlook is provided for the role of CCS in net zero emissions, renewables integration and advancing CCS research. By leveraging innovation across capture, utilization, and storage stages, CCS holds immense potential to play a transformative role in combating climate change and achieving global sustainability goals. � 2024 The Author(s)Item Microplastics in the Atmosphere: Identification, Sources and Transport Pathways(CRC Press, 2024) Arya R.; Rathore J.; Mishra A.K.; Mondal A.Microplastic (MP) pollution is a rising concern due to the overexploitation of plastics and absence of systematic dumping of plastic residue. The size of plastic particles ranging below 5 mm are termed as microplastics. Initial investigations focused on the effects of microplastic pollutants on marine as well as terrestrial ecosystems; however, recent studies have drawn attention to their presence in the atmosphere. The existence of fragmented plastics in the air was first reported in 2016, and thereafter, they were reported to be found in multiple studies conducted various environments, both indoor and outdoor conditions. The deficiency of data and lack of knowledge about their presence can be accredited to their prompt and long-range transport, which is aided by their smaller size. The current challenges with dearth of standard sampling procedures and detection approaches have limited the number of studies on airborne microplastic pollutants. Therefore, there exist large gaps in knowledge about their occurrence, horizontal and vertical distribution and their impact on air quality, ecosystem and human life. This chapter attempts to provide a broad illustration of current state of knowledge regarding atmospheric microplastics. In this chapter, we have attempted to provide an insight into microplastics in the atmosphere, its sources, types, transport pathways and an overview of the present measurement techniques along with its impacts. � 2024 selection and editorial matter, Surajit Mondal, Papita Das, Arnab Mondal, Subhankar Paul, Jitendra Kumar Pandey and Tapas K.
