These components should sustain the extreme environmental conditions throughout their life cycle, without failure. Space missions need lightweight materials which are mechanically strong with high thermal and electric conductivities. Carbon fiber reinforced polymer (CFRP) offers considerable mass saving and high strength, which is widely used for space payload components. However, it has limitations to replace the traditional space-qualified materials due to its low conductivity. Carbon Nanotubes (CNTs) are efficient with greater electrical and thermal conductivities. For CNTs to be seen as effective reinforcements for attaining high strength and conductivity of polymer composites, they need to meet the criteria of being well-dispersed by the solution mixing method. The quality of the CNT nanocomposite relies upon several parameters like the type of CNTs, purity, aspect ratio, amount of loading, alignment and interfacial adhesion between the nanotube and polymer. The performance of the CNT-CFRP composite depends on the successful execution of the processing technique. It has been intended in this review paper to highlight the enhancement of the mechanical, thermal and electrical properties of the composite, and the challenges in achieving it. An attempt has been made to optimize the process parameters to fabricate space payload components which can be excellent alternatives to the existing high-density materials. Moreover, this review research is the need of the hour for prominent space agencies such as ISRO and NASA for their future inter-planetary missions, where payload weight needs to be kept light without making any compromise on the performance index.","PeriodicalId":36296,"journal":{"name":"Journal of Water and Environmental Nanotechnology","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82668997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water quality is of vital concern for mankind as it is related to human health, protection of the environment and sustainable development. Water an essential ingredient and it is present in polluted form in most of the countries in Asia. The deterioration in all aspects of surface and sub-surface water is one of the outcomes of increasing population. All issues related to water from water security to geopolitics, management of water resources to water policies and intervention in natural flow of water to produce hydro-power are governed by the human beings only. The proclamation of Albert Schweitzer in his words “Man has lost the capacity to foresee and to forestall. He will end by destroying the earth” indicates the direction in which this world is heading to. Yuval Noah Harari indicates that “the great discovery that launched the Scientific Revolution was the discovery that human do not know the answers to their most important questions”. Therefore, to save the earth, man needs to rediscover himself. In Anthropocene, all linear anthropogenic activities must be rechecked to find out the missing element to close the loop naturally. This era demands the entire generation to be wise enough to hold and carry the legacy of caring stewardship towards the earth instead of being the brutal exploiter. The time has come to dust-off the concept of defying the nature and begin harmonious relationship to acquire happiness all around in life.","PeriodicalId":36296,"journal":{"name":"Journal of Water and Environmental Nanotechnology","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79940605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The activated carbon was produced by the chemical activation process at varying carbonization temperatures from 600-900 °C for 5 hours in N2 atmosphere. The obtained activated carbon had a high surface area of 1170 m2 g-1 and a total pore volume of 0.5907 cm3 g-1. The surface area of MWCNTs was 216.1 2 m2 g-1 and the total pore volume was 1.5067 cm3 g-1. The as-prepared AC and MWCNTs were characterized by surface area analysis using Brunner-Emmett-Teller method (BET), X-ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopic analysis, Field emission scanning electron microscopy (FESEM), High-resolution transmission electron microscopy (HR-TEM), Energy-dispersive X-ray spectroscopy (EDAX) and DFT (Density functional theory). The electrochemical performance of AC-MWCNTs (25:75) Stainless steel (SS) electrode and Graphite sheet electrode (GE) were studied by cyclic voltammetry, Galvanostatic charge-discharge and electrochemical impedance spectroscopy using 0.5 M Na2SO4 aqueous electrolyte. It has shown a specific capacitance of 174 Fg-1 and 95.26 Fg-1 respectively, using the three-electrode system at a current density of 1 mA g-1. The AC-MWCNT (25:75) SS electrode has exhibited excellent specific capacitance (CSP) and its Specific energy density and Power density were greater than AC-MWCNT (25:75) GE. The electrochemical performance of AC-MWCNT (25:75) SS electrode was identified as a suitable, low-cost and promising energy storage device for future generations. The present investigation attempts to promote the supercapacitor device in the context of available and future technologies for alternative energy systems with outstanding performance.","PeriodicalId":36296,"journal":{"name":"Journal of Water and Environmental Nanotechnology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77511624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
