Intending to the aforementioned property the current investigation leads to carry out the features of the materialistic property of thermal radiation and the dissipative heat by incorporating these in the water-based hybrid nanofluid. The fluid past a stretching cylinder embedded with a permeable medium and the impact of the magnetic field, and thermal radiation are depicted in momentum and energy profiles. In addition to that, the role of the Hamilton-Crosser conductivity model for the behavior of various shapes of the carbon nanotube (CNT) nanoparticles with their volume concentration is also vital. The transformation of the dimensional form of the governing equations into the non-dimensional form is obtained with the use of proper transformation rules. Further, the proposed designed model is handled by employing the traditional shooting-based Runge-Kutta fourth-order technique. The significant properties of different components are deployed graphically and the validation with earlier study shows a good correlation. Moreover, the important characteristics of the outcomes are; the surface cooling, driven by increased thermal buoyancy, promotes fluid velocity while simultaneously influencing the curvature parameter and profile to slow down the accumulation of nanoparticles.","PeriodicalId":44789,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers Part N-Journal of Nanomaterials Nanoengineering and Nanosystems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135185942","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}

Thus, synergistic combination of low adsorption capacity adsorbents may be an effective method to enhance their aqueous contaminant uptake. Sol-gel synthesized lanthanum-1,4-benzene dicarboxylate metal organic framework (LaBDC MOF) and polyethylene oxide (PEO) hydrogel were combined to prepare a synergistic composite adsorbent (PEO-LaBDC) for aqueous methylene blue (MB) adsorption. Major properties of the pristine LaBDC MOF and PEO hydrogel were expressed in the characterized composite indicating successful preparation. PEO-LaBDC composite MB removal rate of MB was at least twice as fast (60 min) to those of the pristine LaBDC MOF (120 min) and PEO hydrogel (125 min). The fitting of kinetics model was fractal in nature, and optimum adsorption was on the alkaline end of the pH spectrum for all adsorbents (pH = 12, 10, and 10, respectively). Comparatively, the composite exhibited a better adsorption performance of ≈177% higher than the pristine LaBDC MOF; buttressing the idea that synergistic combination of adsorbents in composites could enhance adsorption processes. Therefore, the PEO-LaBDC composite is a promising adsorbent for the remediation of aqueous MB.","PeriodicalId":44789,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers Part N-Journal of Nanomaterials Nanoengineering and Nanosystems","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87221181","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 paper different concentration of poly (ethylene) glycol were added to PVA to prepare gel and its nano fibres. PEG is water soluble similar to PVA can give a uniform gel and a strong intermolecular bonding can be achieved by the addition of PEG in PVA. Fibres were prepared by having high wt.% of PEG loaded PVA nano fibres. Nano fibre mat having 0, 0.2,0.4 and 0.6 g PEG having low molecular weight was added in the 8.6 wt.% PVA solution and then fibres were prepared by using electro spinning technique. Nano fibres so prepared were characterised by SEM, XRD and DSC. SEM results reveal that increase of PEG concentration separated the nano fibres and increased the gap of the mesh size. SEM micro graphs depicts that produced nano fibres are homogenous in nature and there were no apparent gap between the PVA and PEG nano fibre. It may be explained that due to the high electric potential developed during the electro spinning process which helped the nano fibres to get stretched XRD patterns exhibited the crystal size increased on adding PEG in the PVA gel. Effect of PEG addition on Tm of PVA nano fibres has been determined by running their DSC scans. An additional peak of 158.13°C is observed for the sample having 0.4 g PEG. Melting temperature shifted from 215° C to 219°C due to increase in crystal size of PEG added PVA nano fibres.","PeriodicalId":44789,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers Part N-Journal of Nanomaterials Nanoengineering and Nanosystems","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88572377","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 nanorod is assumed to be thick, and it is modeled based on Bishop theory of rods. In thick nanorods, the effects of the inertia of lateral motions and the shear stiffness are considered in the kinetic energy and the strain energy of the nanorod, respectively. In the present study, the crack is modeled as a linear spring in which its stiffness is related to the crack severity. The surface parameters considered are the surface Lamé constants, the surface density, and the surface stress. Considering all surface parameters causes inhomogeneity of governing equations and boundary conditions. After converting inhomogeneous equations to homogeneous ones, the resulted equations are solved numerically. All possible boundary conditions are introduced but only natural frequencies of nanorod with fixed-fixed and fixed-free are reported. In addition to considering the effect of type of boundary conditions on the natural frequencies, the effect of geometrical parameters like radius and length, and mode number is also considered. The results are presented for both thin and thick nanorods to compare the effect of various parameters especially surface parameters on longitudinal frequencies.","PeriodicalId":44789,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers Part N-Journal of Nanomaterials Nanoengineering and Nanosystems","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85345119","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}

To perform the SCS process, a reactor was designed and constructed and the synthesis process was performed using cobalt (II) nitrate-6-water as oxidizer along with glycine and urea as fuels. The effect of the molar ratio of glycine fuel to oxidizer and fuel type parameters on the purity of the products were examined. The XRD and FESEM analysis were used to characterize the obtained products. Based on FESEM analysis and the Scherrer equation, the mean size of all samples was under 100 nm and the reactor loaded with the glycine fuel provided the lowest particle sizes by around 14 nm and produced particles with better surface adhesion. It was found that the glycine fuel was determined the best fuel compared to urea because of producing temperatures near 400°C. Compared to traditional gas-solid reactions, the operating temperature of this process was under 400°C which was considerably lower than the operating temperature of gas-solid reactions occurred at temperatures higher than 800°C.","PeriodicalId":44789,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers Part N-Journal of Nanomaterials Nanoengineering and Nanosystems","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89269133","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}

Thermal radiation, viscous dissipation and prescribed surface slip condition is also imposed in order to acquire physically realistic analysis. The flow governing problem is modeled using fundamental laws of momentum and energy which afterward is transformed by utilizing a suitable scaling analysis. Role of emerging sundry parameters on quantities of physical interest are portrayed graphically and discussed in a physical manner. It is observed that fluid’s velocity and temperature rises for radiation parameter but concentration of fluid drops down.
