The clay was treated with hydrochloric acid to identify the characteristics. This paper explains XRF, FT-IR, XRD, SEM, and TGA characterization of commercially available sodium bentonite clay, a potential catalyst for thermo- catalytic pyrolysis in waste plastic valorization. Phase identification, structural properties, and chemical compositions were investigated. Less value of a loss on ignition (LOI) was found as 9.8% by weight which shows better acceptance performance for thermo- catalytic process of plastic wastes recycling. SiO2 (52.55%), A12O3(15.34%), and Fe2O3 (11.92%) three major compounds were identified by XRF and satisfy the XRD pattern. Spectra show that at 1009.25 cm−1, 1032.05 cm−1and 1112.90 cm-1 band positions are strong bands of Si-O stretching of monosubstituted and tetrahedral compounds. Alcohols and phenols group of compounds have sharp band positions of H- O-H stretching at 3620.59 cm−1and 3695.17 cm−1. The maximum average crystallite size was found 26.55 nm for 25.09° (2Θ) absorption. The morphology indicates that the presences of large particles are in the form of agglomerates. The high weight percentage of SiO2 and CaCO3 were spotted respectively 45.40% and 42.18% by weight for raw clay in the scanning electron micrograph. After acid treatment, it was found that the % weight of CaCO3 was decreased as 20.99% and % weight of SiO2 was increased as 48.88%. Thermo gravimetric graph shows that the reliable temperature range is 450°C to 500°C, which satisfies the pyrolysis process temperature range. The objective of this paper is to explore the similar utilization of the montmorillonite group of clay as a catalyst and useful engineering aspects for recycling plastic wastes.","PeriodicalId":243805,"journal":{"name":"2019 3rd International Conference on Electronics, Materials Engineering & Nano-Technology (IEMENTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130353395","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}

Secondly the proposed automation is expected to skip the total darkness when the cinema hall is empty during non operational hours. The proposed hardware sensor has been prototyped in Orcad pspice simulation and the model reliability has been verified based on voltage and time parameters to identify the trigger threshold. We will enable using a relay based circuit which will have different configurations enabled with a counter for a circuit for the entire cinema time period.

Presence of C60nanoparticles reduce barrier height and provides easy path for charge percolation. We have used ITO coated glass as front electrode and aluminium as back electrode to form the organic device. This organic device has been prepared with and without C60nanoparticles by using spin coating technique. We have measured the steady state current-voltage (I- V) characteristics of the device to estimate barrier height (Φb) of the device. Φbis reduced from 0.87 eV to 0.75 eV in the presence of C60nanoparticles. The barrier height is also estimated by using another alternative method which is known as Norde method. By using Norde method, Φbis estimated which reduces from 0.83 eV to 0.79 eV in presence of C60nanoparticles. Both the methods show good consistency with each other. Reduction of the interfacial barrier height in presence of fullerene indicates the enhancement of charge injection through the metal - organic dye interface. By suitable addition of C60nanoparticles within the CV dye it is possible to modify the barrier height and enhance the current injection through metal-organic dye interface which also allows the device to be turned on at much lower voltages.","PeriodicalId":243805,"journal":{"name":"2019 3rd International Conference on Electronics, Materials Engineering & Nano-Technology (IEMENTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129184317","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}
