Well-established and intuitive material properties of the bulk material do not hold at the nanoscale. The high surface area to volume ratio of nanoparticles result in counter-intuitive property enhancements in comparison to their bulk counterparts. Stable suspensions of nanoparticles in various solvents is termed as nanofluid. The material properties of nanoparticles can be tuned. As a result, nanofluids can be synthesized with tunable material properties that are responsive to external stimuli (\"smart fluids\"). This makes these materials attractive targets for deployment in various segments of the oil and gas industry. Nanofluids and nano-composites confer several advantages: such as enhanced strength, enhanced thermal conductivity, enhanced heat transfer area, enhanced oil recovery, enhanced magnetic properties, light-weight, resistance to corrosion, erosion, wear and tear. These afford various unconventional applications of nanofluids in the oil and gas industry. This provides an excellent value proposition for researching their synthesis methods and their working mechanisms. Nanofluids are synthesized by adding very minute concentrations of nanoparticles in the base fluid, leading to the formation of a colloidal suspension that is superior in the rheological, mechanical and thermal properties as compared to the base fluid (neat solvent). In this review the synthesis protocols reported in the literature are explored to ascertain their competitiveness for the oil and gas industry. Nanofluids were found to be attractive for applications ranging from exploration, drilling, and production.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"31 1","pages":"455-460"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91018976","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 this work, the design of a miniaturized fuel cell, with integrated MWCNT coated LIG electrodes, has been presented. Here, Formic acid acts as fuel, and Sulphuric acid acts as an electrolyte for the proposed fuel cell. Rigorous investigations have been performed to enhance the performance of fuel cell with optimization of parameters such as catalyst, electrode types, the concentration of fuel and electrolyte solutions, etc. The platform is able to generate an optimum current density as 82.27 μA/cm2, and power density as 2.54 μW/cm2, at a stable OCP of 110 mV, while MWCNT/LIG is used as electrodes (anode and cathode). Such LIG electrodes have numerous advantages including low cost (≤$1), higher efficient, ease of fabrication, flexibility, and ease of application.

In the present study, we examined the influence of multi-jet (32 jets) electrospinning with a randomized approach focused on three variables, which are feeding rate, the voltage applied, and tip-to-collector distance. Furthermore, the effect of single and double layer piezoelectric nanogenerator (PENG) was demonstrated under the pendulum impact loadings. The prepared nanofiber structures were characterized using FE-SEM, FTIR, and XRD. Outcomes from the morphological analysis appeared that the spinning parameter, the tip-to-collector distance, plays a crucial role in the formation of beads free with uniform distribution of nanofibers and β-phase formation. The fabricated PENG was able to generate a maximum open-circuit output of 24 V at 2.5 N from 50 μm thick nanofiber web under a single impact. In this way, the output voltage generated is sufficient for the operation of nanoelectromechanical systems (NEMS), low-power electronics and energy harvesting.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"1 1","pages":"500-505"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76507305","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 significance of bioelectrodes employed in biofuel cell design is highly dependent on the effective immobilization of enzyme to enable the enzyme to present an orientation that is favorable for direct electron transfer (DET) from the active center of the enzyme to the final current collector. We examined chitosan and nafion-chitosan based coatings on immobilized pyrroloquinoline quinone dependent glucose dehydrogenase (PQQ-GDH) and bilirubin oxidase (BOD) as anodic and cathodic enzymes, respectively. The enzymes were immobilized on multi-walled carbon nanotubes (MWCNTs). The performance of the assembled biofuel cells exhibited interesting operational stability. Operating under DET, the biofuel cell with bioelectrodes coated with chitosan produced the highest power (156 μW) output. PQQ-GDH bioanodes with various enzyme concentrations were evaluated to access their performance and stability. The bioanode with 2.5 mg/ml immobilized PQQ-GDH demonstrated long term stability and generated a maximum power density of 1.6 mW/cm2 in the fuel cell assembly when compared to higher enzyme load concentration (≥ 5 mg/ml PQQ-GDH).","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"42 1","pages":"416-419"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78501950","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 prepared nanofibers have piezoelectric properties, which are characterized by the content of ß-phase. Another way to improve the piezoelectric properties is to use TiO2 nanoparticles, which increases the piezoelectric effect. Piezoelectric effect is strongly connected with capacitive properties which was investigated in this work. Capacitive sensor with a sandwich structure consisting of EVA foam as a cover, conductive copper fabric and nanofibers was prepared. The sensor is light-weight, flexible with the possibility of using for wearable electronics. We can therefore determine the maximum pressure at individual points of the foot, the course of its values, the method of pressure distribution throughout the foot. We can find use not only in research on walking, running and postures, but also, provide information on the magnitude of the applied force over time. The force converted to the selected sensor area is then pressure information.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"23 1","pages":"115-119"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88681145","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}
