Bone transplantations often needs restoration to the damaged bone. However, autografts still have some limitations. This study aimed to provide a region-specific immobilization of growth factors (GFs) in the scaffolds, which in turn can help in differentiating of BMSCs into three different cells in the same scaffold. The exposure tert-butyl hydroperoxide (t-BHP) aging model of BMSCs was reverted <i>in vitro</i> by using CNT-IGF-PCL-PLA scaffolds. Polystyrene (PS) region-specific immobilized GFs was then used by interference and diffraction of ultraviolet (UV). In addition, the reverted BMSCs were regionally differentiation into three kinds of cells. <i>In vivo</i>, GFs-PS scaffolds accelerate bone healing in injured Sprague-Dawley (SD) rats after treatment for 21 days. The CNT-IGF-PCL-PLA scaffolds demonstrated good biological and chemical properties, and the external experiments showed significant resistance of senescence in BMSC. Meanwhile, GFs-PS effectively promoted the differentiation of reverted BMSCs in the designated area on day 21. These results suggested that GFs are localized by co-immobilization on PS for the first time by optical interference and diffraction of UV light, which isconsidered as a short-time, low cost, and simple operation method.","PeriodicalId":18731,"journal":{"name":"Materials Processing & Manufacturing eJournal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90471072","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}

RCB plays a major role in rotating parts under high speeds and loads and are widely used in many machinery components. The defect or malfunctioning in this rolling elements leads to severe consequences in productivity and also costly downtime. So if we could monitor these rolling elements and could predict the severity of defect prior to they actually happen much advantage could be gain than after failure of rolling elements. Therefore vibration monitoring was used to detect various defects. This paper also shows compatibility of Vibration analysis technique for detecting the distributed defects in rolling elements. Experimental analysis is done on roller bearing with different load condition (1kg ,2kg,3kg) and without load condition with respective to speed of shaft in rpm (1000,2000,3000) . Then the comparison is carried out between healthy and defective bearings on the basis of results obtained from FFT analysis. The results extracted from experiments are presented and explained in detail.","PeriodicalId":18731,"journal":{"name":"Materials Processing & Manufacturing eJournal","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77660879","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}

Now a day’s reduction in friction is a major and ongoing task for researchers. Few researches are focussing on various Nano additives that lower value of friction and hence wear can be reduced. Therefore, the main objective of this paper is to determine the anti-wear characteristics of the lubricant along with extreme pressure point. Further, also determine the physiochemical properties. In this research coconut oil is used as a lubricant and hexagonal boron nitride (h-BN) is used as friction modifier. The ultrasonic homogenizer was used for mixing of friction modifier with lubricant. Further, four ball test rig was used to obtain the extreme pressure, coefficient of friction and wear scar. After test, balls were characterized using 3D optical profilometer and scanning electron microscopy. From the results, it is observed that 2.5 wt % h-BN with coconut oil gives low coefficient of friction, high extreme pressure with moderate wear scar. Finally, Comparison with commercial mineral oil (CMO), the newly developed additive oil combination is having excellent properties and it can be used as a substitute as it is biodegradable, nontoxic, easily manufactured and environment friendly.","PeriodicalId":18731,"journal":{"name":"Materials Processing & Manufacturing eJournal","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87582125","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}
