Uncarbonized (UPSp) and carbonized (CPSp) periwinkle shell particle was used in the production of the composites at 0, 10, 20, 30 and 40wt%. The influences of wear parameters like applied load, sliding speed and percentage of periwinkle shell particles addition on the wear rate were investigated. A plan of experiments was performed to acquire data in a controlled way. Scanning electron microscope was used to analyze the worn surface of the samples. Linear regression equation and analysis of variance (ANOVA) were employed to investigate the influence of process parameters on the wear rate of the samples. The carbonized (CPSp) composites have a higher wear resistance than the uncarbonized (UPSp) composites. The predicted wear rate of the epoxy and it composites were found to lie close to that experimentally observed ones. The confirmation of the experiments conduct using ANOVA to verify the optimal testing parameters shows that periwinkle shell particles, sliding speed and applied load had a significant effect on the wear rate. The results show that the addition of periwinkle shell particles as reinforcing materials in epoxy composites increases the wear resistance of the composite greatly.","PeriodicalId":17291,"journal":{"name":"Journal of the Chinese Advanced Materials Society","volume":"1 1","pages":"123-139"},"PeriodicalIF":0.0,"publicationDate":"2016-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80517591","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 investigated samples consist of thin a-Si:H/ SiC:H layers deposited on clean crystalline Si(100) substrate. The structures were passivated by means of three types of chemical procedures based on aqueous and/or methanol solution of KCN. \u0000 \u0000PL signals consist of a few partially overlapped Gaussian peaks. The shape of the PL spectrum is modified depending on the applied passivation method. This can be interpreted as a result of the diverse influence of the passivation on individual energy peaks. In our opinion, this confirms the assumption that the excited states that are contributing to the intensity of these peaks are localized in different zones of the sample, namely at different depths. We demonstrate the effect of substrate on the layers' structural parameters. Surface roughness was determined using the atomic force microscopy (AFM) method. X-ray diffraction at grazing incidence (XRDG) measurements confirm the non-homogeneity of deposited films that result in zones. The process of passivation modifies the densities of states that generate PL peaks differently in accordance with their localization. The diffusion of cyanide anions CN− in the amorphous matrix of the a-Si:H layer is the mechanism that controls this effect.","PeriodicalId":17291,"journal":{"name":"Journal of the Chinese Advanced Materials Society","volume":"64 1","pages":"62-69"},"PeriodicalIF":0.0,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91148856","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 electrochemical oxidation (anodic) method is employed for oxidation of layered composite. The structural and morphological studies of these films are investigated using X-ray diffraction and scanning electron microscope. The electrochemical supercapacitive behavior of the films is studied using cyclic voltammetry and galvanostatic charge–discharge measurements in 0.5M Na2SO4 electrolyte bath. The layered composite PANI/Co3O4 electrode shows almost 50% increase in specific capacitance and remarkable enhancement in specific energy and specific power in comparison with the parent Co3O4 electrode. For layered composite electrode after 500 cycles of charge–discharge, it is observed that specific capacitance retains ∼ 100% compared to the first cycle. The electrochemical impedance spectroscopy is also studied. The simulated values of resistance and capacitance are calculated along with equivalent circuit. Hence, the layered composite PANI/Co3O4 electrode may have great potential application for electrochemical supercapacitors.","PeriodicalId":17291,"journal":{"name":"Journal of the Chinese Advanced Materials Society","volume":"367 1","pages":"13-23"},"PeriodicalIF":0.0,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76428302","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}
