In this work, the tribological properties of the Simarouba glauca biodiesel (SBD) are studied with nanoparticles as additives. Nanoparticles of copper oxide (CuO) and silicon dioxide (SiO2) were added with 0.2, 0.5, 0.75, and 1% weight (wt) in the base SBD. The coefficient of friction (COF) and the wear scar diameters (WSD) were evaluated using four ball tester for the test conditions as per ASTM D 4172 standard. The morphologies of the worn surfaces were inspected by scanning electron microscope (SEM). The addition of nanoparticles improved the friction and wear characteristics of SBD. A combination of abrasive and adhesive wear was evident. The average COF for pure SBD was 0.0168. The results indicated that 0.75% and 0.2% of CuO nanoparticles as a beneficial percentage in the base oil exhibiting the lowest COF and WSD. CuO nanoparticles proved to be superior to SiO2 nanoparticles as additives in SBD, demonstrating 8% and 60% decrease in wear and friction parameters, respectively.","PeriodicalId":145165,"journal":{"name":"Research Anthology on Synthesis, Characterization, and Applications of Nanomaterials","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127898219","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}

Optical microscope and scanning electron microscope (SEM) are used to visualize the microstructural phases and distribution of reinforcements respectively. Main effect plots and interaction plots are analyzed to find the effect of selected parameters and their interactions. Analysis of variance (ANOVA) is also carried out for response variables to find the significant parameters. Linear regression equations are also generated to relate the output and input parameters.

The addition of ZnO into the PS film is found to decrease the optical band gap (OBG) from 4.07 eV to 1.86 eV. Frequency dependence of dielectric constant (ε′), loss tangent (tanδ), ac conductivity (σac) and electromagnetic (EM) interference shielding effectiveness (SE) studies have been undertaken on the pure PS and PS/ZnO films. Insertion of ZnO into pure PS polymer matrix is found to enhance ε′, tanδ, σac, and SE considerably. The ε′ and tanδ were reduced with an enhancement in the frequency. σac of PS/ZnO nanocomposites was enhanced with rise in frequency and electrical conduction process in PS/ZnO film is in agreement with an electron-hopping model. EM interference SE is reduced with rise in the frequency. PS/ZnO films were proven as a favorable functional substance for the absorbing of EM waves at lower frequencies.","PeriodicalId":145165,"journal":{"name":"Research Anthology on Synthesis, Characterization, and Applications of Nanomaterials","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123755631","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}

Bioremediation is defined as a waste management technique that involves use of organisms to remove or neutralize pollutants from a contaminated site. This involves no use of chemicals and it allows waste to get recycled; this process has evolved as one of the most important methods. Remediation of contaminants using existing conventional technology is neither effective nor efficient in environmental cleanup. Techniques developed from nanobiotechnology can detect, control, and remediate pollutants by acting as sensors. Use of nanomaterials has less toxic effects and this will not only reduce consumption time but also reduce cost. Nanoparticles developed by using microbial systems provide green nanotechnology and help in keeping the environment clean. Green nanotechnology needs to develop to make cleaner environment with great ecological balance on earth. This chapter deals with traditional methods of bioremediation, methods in nanobiotechnology, and future aspects.","PeriodicalId":145165,"journal":{"name":"Research Anthology on Synthesis, Characterization, and Applications of Nanomaterials","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122639031","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 transparency of safety issues and impact on environment should be the prime focus while engaging a particular field with nanotechnology. Testing of nano products needs to be enforced before they are released to the market. Whether nanotechnology is good or bad for the environment is totally based on the nature of its use and considerations made during its application. The use of nanotechnology in any field requires great care, and any sort of negligence is likely to bring negative effects for the environment and its habitats. Recent studies show that the lack of knowledge as regard risks is found even at the expert level.

The substrates were grit blasted to obtain mechanical fixation of the generated nanotubular TiO2 structure. This was successfully achieved without diminishment of the nanotubes order and with a self-leveling of the outer surface. A new phenomenon has been investigated consisting of the process of oxidation of the nanotubes in water after anodizing. Along this process, methyl orange added to the aqueous solution was discolored as part of the redox reaction involved. The final state of the modified layer was composed of conglomerates of almost completely crystalline TiO2 nanoparticles, around 4 nm in size, consisting of anatase. SEM and TEM images show the transition of the amorphous nanotubes (atomic disorder/nanometric order) to crystalline disordered particles (atomic order/nanometric disorder).","PeriodicalId":145165,"journal":{"name":"Research Anthology on Synthesis, Characterization, and Applications of Nanomaterials","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132518618","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 UV–Vis diffuse reflectance spectra of the CoTiO3-TiO2 composite showed an absorption wavelength, in the visible light region, having a band gap energy value of 2.21 eV.
