However, the production of biodiesel faces a major hurdle in obtaining high purity and easy separation of the main product from glycerol. Researchers worldwide are focusing on finding new sophisticated materials that may help to develop a sustainable eco-efficient process. Only a limited number of review articles have been published that cover the use of a catalyst and co-solvent for easy separation of biodiesel from glycerol. In this paper, assessment of various catalysts (homogeneous and heterogeneous), ionic liquids and deep eutectic solvents (green solvents) for biodiesel production is reviewed. This will help researchers to find an excellent combination and economic feasibility for biodiesel manufacturing meeting environmental standards. This will provide a solid background for future research.

Bulletin of Materials Science, 2013

For the synthesis of MWCNTs it is necessary to optimize the process for the objective parameter such as better yield or quality. This needs to be done for each precursor type. To achieve the twin objective of physical optimization of the process parameters for better yield and acceptable quality for each precursor type poses almost an impossible task because of time and cost involved. However, a statistical technique such as Taguchi robust technique is expected to be an efficient and effective tool to do this. The process needs to be optimized for each of the precursors selected for MWCNT synthesis for higher yield and acceptable relative quality conforming to requirement of applications. In this chapter, a few parameters that influence the yield and quality of CNT have been identified. Taguchi robust technique is employed which not only helps to optimize the parameters but also analyse the extent of effect of each parameter on the synthesis. 3.1. Introduction In the earlier chapter, the potency of six plant based precursors for CNT synthesis was outlined with details of synthesis and characterization of CNTs which were multiwalled in nature. The yield and quality of those MWCNTs depend on various process parameters like temperature of synthesis, flow rate of carrier gas, catalyst type and characteristics. Thus, it becomes very important to explore the optimum conditions for better yield and acceptable quality for synthesis of MWCNTs from the six screened plant precursors. The work in this chapter is an attempt to use Taguchi robust technique for determining the optimum conditions for MWCNT synthesis form plant based precursors.

Lipases are produced by various microbes, such as bacteria, fungi, yeast, and also in the pancreas of mammals, like pigs and humans. Commercially useful lipases are usually obtained from microorganisms that produce a wide variety of extracellular lipases. Only about 2% of world’s microorganisms have been tested as enzyme sources. In the present study different oil contaminated soils were taken for isolation of lipolytic organisms. Different samples were collected and isolation of lipolytic microorganisms is done by standard plate assay method. This methodology helps in getting cultures with less contamination and abundance of bacteria can be minimized by using antibiotics in culture medium Totally seven strain were isolated, out of se...

The course emphasizes on the dynamic behaviour, physical and empirical modeling of bio-systems and advanced control strategies. The primary objective of process control is to maintain a process at the desired operating conditions with quality standards in an economic way and with safety aspects in place. In this backdrop, the present study was implemented as an exercise and structured inquiry experiments in Bioprocess Control Laboratory for VI semester undergraduate students of Biotechnology engineering. The course was hitherto taught in a conventional approach with analysis and interpretation of dynamic responses of different systems with standard inputs. The delivery of the exercise was implemented in three phases namely training, execution and assessment phase. In the present study dynamic response of control system was predicted with models and then compared with experimental observations. The resulting deviations therein, were analyzed for the possible underlying reasons and a chisquare goodness of fit test was performed to validate the model. The assessment of the students' performance was done on individual basis through a Rubrics-based approach and attainment of the Program outcomes addressed was recorded which ranged from 80-95%. The study helped in addressing the graduate attributes related to the investigation of complex problem, analyze the correlation of the experimental outcomes with underlying theoretical concepts and interpretation of results. A formal feedback from the students revealed that the active learning approach enhanced the understanding of the control engineering concepts through the application of statistical modeling and analysis.
