The degradation of PET bottles has been successfully achieved using hydrotalcite as catalyst and dimethyl sulfoxide (DMSO) as solvent. The reaction was carried out at boiling point of DMSO (190°C) and degradation was complete in 10 min. The oligomer (tetramer) obtained was treated with NaOH at room temperature in methanol to get dimethyl terephthalate (DMT) and ethylene glycol (EG). Thus, it is a safe and cleaner process. Oligomer was characterized by MS,13C‐NMR, X‐ray diffractometric, and thermogravimetric analysis. DMT and EG were characterized by GC‐MS. DMT was also characterized by FT‐IR. GC‐MS analysis shows that the purity of DMT was 99%. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2012

The three‐point bending behavior of sandwich beams made up of jute epoxy skins and piecewise linear functionally graded (FG) rubber core reinforced with fly ash filler is investigated. This work studies the influence of the parameters such as weight fraction of fly ash, core to thickness ratio, and orientation of jute on specific bending modulus and strength. The load displacement response of the sandwich is traced to evaluate the specific modulus and strength. FG core samples are prepared by using conventional casting technique and sandwich by hand layup. Presence of gradation is quantified experimentally. Results of bending test indicate that specific modulus and strength are primarily governed by filler content and core to sandwich thickness ratio. FG sandwiches with different gradation configurations (uniform, linear, and piecewise linear) are modeled using finite element analysis (ANSYS 5.4) to evaluate specific strength which is subsequently compared with the experimental results and the best gradation configuration is presented.

“…Hence, a 1200 kV ultra high voltage (UHV) experimental transmission line research facility is set up near Bina in Madhya Pradesh state of India and has been successfully charged to full voltage in the year 2012. This is achieved with the participation of public and private sector power utilities and power system equipment manufacturing companies for further exploring the possibilities and advantages of high voltage transmission [3][4][5]. The challenging issues for development of such a system are minimization of right of way, protection of flora, fauna and wild life, creation of long distance high capacity transmission corridors to enable minimum cost per MW transfer as well as optimize transmission losses, minimum environment impact and strengthening of national grid [6][7][8].…”

The development of extra and ultra high voltage transmission lines are becoming essential due to ever increasing energy demand worldwide. In order to strengthen the transmission infrastructure, transmission utilities are aiming at constructing high voltage and high power intensity power transmission lines for meeting the energy requirements with maximum possible efficiency and minimum adverse environmental effects. Extra and ultra high voltage transmission lines have been developed and being operated successfully in the developed nations. Recent trends in Indian transmission scenario are progressing towards establishing these lines. In the present study, an attempt has been made to present the design aspects of 765 kV transmission lines briefly. A detailed techno-economic analysis evaluating the benefits and costs resulting from these lines in power transmission has been carried and the results are summarized.
