With production rates higher than ever and rapid, unsafe disposal of used polymers, it has taken a toll on the environment and other species through pollution. Even though there are alternative solutions, including bioplastics manufactured from greener sources and biodegradable plastics that can disintegrate in a shorter time period, these alternatives are currently in their early stages and hence expensive. They are also more challenging to meet the high demands in terms of both quantity and properties. The next nearest alternative, recycling, is another best available solution to avoid plastic waste entering landfills and to reduce raw material demands. This study aims to determine the effectiveness of a newly introduced SEBS-based property enhancer (WinMod 300) with disposed HIPS (High Impact Polystyrene) and a Maleic Anhydride-grafted SEBS compatibilizer (WinMod 110) with disposed multilayer films (LDPE and Polyester layers). Recycled compounds were tested for necessary and significant mechanical properties and material characterization techniques, and the results are presented in this study.","PeriodicalId":44365,"journal":{"name":"Nanomaterials and Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138620635","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 deposition process utilized a biased enhanced nucleation technique (BEN), varying the flow rate ratio of H2 and CH4. Our investigations revealed that increasing the CH4 flow rate led to a reduction in grain size and an augmented nucleation density of HDLC, as evidenced by contact mode atomic force microscope images. This study demonstrates the effective control of diamond grain growth by introducing high CH4 concentration pulses during deposition. The field emission characteristics of HDLC samples were analyzed, revealing threshold fields of 12.2 V/μm for nanocrystalline films, 8.5 V/μm for sub-crystalline films, and 4.1 V/μm for microcrystalline films, corroborated by Raman spectra. Surface energy measurements indicated hydrophobic behavior in the samples. Notably, a decrease in the H2/CH4 ratio was found to increase the sp2 character, which correlated with the emission field. Atomic force microscope (AFM) analysis of HDLC samples yielded surface roughness values ranging from 0.2 nm to approximately 0.01 nm, affirming the continuous, nonporous, and smooth nature of the surfaces.","PeriodicalId":44365,"journal":{"name":"Nanomaterials and Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138608838","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}

Scientists and engineers have developed innovative techniques in nanotechnology and material science, particularly in eco-friendly synthesis of metal oxides, to address these challenges. This review discusses current trends in eco-friendly synthesis and technological applications of ZnO nanostructures beyond the biomedical field mostly presented in the literature. Green synthesis methods of ZnO have attracted researchers due to their low toxicity, versatility, and environmentally friendly nature. ZnO nanoparticles (NPs) possess unique optical and thermal characteristics, a wide band gap, high excitation binding energy, and GRASE status, contributing to their broad range of applications. Conventional synthesis methods were reported to have potential toxicity effects, while green synthesis offers recognized advantages. The review also explores the mechanism of ZnO NP formation. Moreover, this review provides an overview of diverse applications of ZnO NPs, including energy devices (solar cells), cement concrete, sensors, water and environmental remediation, enhanced oil recovery (EOR), coolants and biomedical. Further studies are recommended to explore additional properties and applications of ZnO NPs using the latest environmentally friendly approaches.","PeriodicalId":44365,"journal":{"name":"Nanomaterials and Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46897748","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 country is also endowed with wind energy in its large coastal areas. India is an agro-economic country that has a growing need for irrigation. Utilization of hybrid renewable energy for the agricultural needs of the country would be a step towards a sustainable future. For the environmental conditions of Haldia, a standalone Photovoltaic-Wind-Lead Acid Battery hybrid renewable energy system (HRES) was developed to cater to the need of agricultural activities. The investigation is conducted for the impact of PV penetration on the system’s wind energy capacity, battery capacity, capacity shortage, net present cost (NPC), cost of energy (COE), PV and wind energy percentage, and surplus energy produced. The optimization is based on the assumption that the HRES has no unmet load and the lowest COE. The research provides a range of Wind energy capacity for the location with no unmet loads. The research discovers the site’s ideal HRES with a COE of 0.312 $ per kWh. This study may help farmers by boosting their reliance on power from renewable energy sources and decreasing their dependency on grid power for agricultural activities.","PeriodicalId":44365,"journal":{"name":"Nanomaterials and Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46779787","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}

It represents a visionary pathway towards a future where humanity can thrive without compromising the delicate balance of our planet’s ecosystems. This transformative journey acknowledges the imperative of reducing carbon emissions, mitigating climate change, and fostering energy security. The roadmap to a sustainable future through energy transition is a multifaceted endeavor that spans technological innovation, policy reform, and societal engagement. As societies worldwide confront the challenges posed by climate change, the need to transition from fossil fuels to renewable and low-carbon energy sources has become paramount. This transition involves a meticulous orchestration of efforts aimed at curbing greenhouse gas emissions, enhancing energy efficiency, and ensuring the equitable distribution of energy access.This study looks into the technological and financial implications of an accelerated energy transition by 2050, with the help of new data on renewable energy. It is suggested that this shift will be largely driven by energy efficiency and renewable energy technologies, which have a significant relationship. Favorable profitable conditions, quickly accessible resources, scalable technology, and significant socioeconomic benefits provide support to the energy transition.","PeriodicalId":44365,"journal":{"name":"Nanomaterials and Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48676619","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}

In particular, methods are needed to characterize mechanical properties with nanometer lateral resolution, in order to understand the contribution of the nanosized features of the materials and the related phenomena. Atomic force microscopy (AFM) has been evolved from a tool for the morphological analysis of the sample surface to an integrated platform for the physicochemical characterization of samples. Current AFM systems host several advanced techniques for the mechanical characterization of materials with high speed and high lateral resolution in a broad range of mechanical moduli, e.g., from stiff samples (e.g., coatings, crystals…) to soft materials (e.g., polymers, biological samples...), in different environments (e.g., air, vacuum, liquid), and conditions (controlled humidity, controlled temperature).
