However, the effective applications of nanofluids have limitations such as poor stability, sedimentation, erosive wear and potential health risk. In heat transfer application point of view, stability of nanoparticles plays a major function in enhancing heat transfer. In this experimental investigation, the stability of Multi-walled Carbon Nano Tube (MWCNT)/water nanofluids with surfactant and without surfactant has been carried out by keeping the nanofluids at static condition and at constant temperature at different time interval. The nanofluids were prepared by means of the use of Multi-walled Carbon Nano Tube (MWCNT) as base materials and distilled water as base fluids at 0.1%, 0.3%, 0.5% and 0.7% volume concentration with 0.02% and 0.05% sodium dodecyl butane sulfonate (SDBS) as surfactant and without the surfactant two-step method is used to put together the nanofluids underneath attention. The stability analysis of prepared nanofluids are studied with the UV-Vis. spectrophotometer, measure of zeta potential value , and photograph capturing techniques by keeping the nanofluids under static condition for The MWCNT nanofluids have been characterized with the sample of just after preparation after 30 days of preparation and after 60 days. It is studied that the nanofluids with surfactant showed better stability than the nanofluids without surfactant. Found that the nanofluids at 0.7% volume concentration with surfactant showed good stability with negligible visual sedimentation even after 60 days than the nanofluids without surfactant. Therefore the MWCNT/water nanofluids are the potential heat transfer fluids to apply in heat transfer field.

In this research work, an attempt has been made to study the effect of process parameters of WEDM on the Surface roughness. Input process parameters considered in this work are Pulse on time (T ON ), Pulse off time(T OFF ), Wire Feed (WF), Wire Tension(WT) and the Surface Roughness as response. Al 7075 Aluminium alloy was taken as work material and Brass coated copper wire as electrode to machine and the values of roughness obtained by varying the input process parameters were analysed using Taguchi method (L 27 orthogonal array). The measured values have been used to develop the mathematical model and the accuracy of the model was tested using Analysis of Variance (ANOVA) technique. Based on the predicted values the interaction graphs, were drawn between the Surface roughness and the process parameters taken for this study. It was construed that the pulse-on time has the highest impact on the Surface roughness followed by the Wire feed, Wire tension and the Pulse-off time. The surface roughness got increased with increase in wire feed. Finally optimum parameters have been arrived to achieve better surface roughness. WEDMed surface was also examined by using scanning electron microscope (SEM) and evinced that the physical behaviour of these process parameters on Surface roughness.

The present research work aims on synthesis of pristine CeO 2 nanoparticles by precipitation method and was thoroughly characterized by Fourier Transform Infrared spectroscopy, X-ray Diffraction, UV-vis-Diffuse Reflectance Spectroscopy, High Resolution Scanning Electron Microscopy, EDAX and Electron Spin Resonance techniques. The band gap energy (E bg ) was found to be 3.19 eV. The synthesized nanomaterials showed spherical morphology and the particles size ranged from 50-93 nm. The insitu generation of · OH radicals was confirmed from ESR studies. The synthesized CeO 2 nanospheres was evaluatedin photocatalytic oxidation of an azo dye Acid orange 10 under Ultraviolet and visible light irradiations. Experimental studies such as pH, catalyst amount and effect of initial dye concentration were also studied. Kinetic studies indicate the photo reaction follows pseudo-first order rate equation. The photocatalytic oxidation of dye molecules were monitored by UV-visible spectroscopy and COD analyses. The level of chemical oxygen demand (COD) of the photodegraded samples decreases in both the photocatalytic systems indicating that dye molecules readily degraded under present experimental conditions.Effect of electrolytes like MgSO 4 ,KCl, Na 2 CO 3 and NaHCO 3 were also investigated to check interference of inorganic anions on photocatalytic oxidation of dye molecules using CeO 2 nanospheres. Finally, the prepared catalyst was checked for its reusability and the photocatalyst exhibited better photocatalytic activity evenafter three cycles of regeneration.Copyright © VBRI Press.","PeriodicalId":7297,"journal":{"name":"Advanced Materials Proceedings","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75702720","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}

XRD showed the prepared nanomaterial to be in a nano range with high crystallinity.
