As a novel study, esterification of acetic acid with methanol has been studied in a simple batch reactive distillation apparatus to produce methyl acetate as main product and water as byproduct. Novel solid catalyst named Indion 180 has been used in this esterification process. The product methyl acetate can be distilled out in two ways namely sequential and simultaneous reactive distillation. In the simple distillation batch process, first the reaction is carried out till the equilibrium with total reflux of vapours, and then distillation is carried out where the vapours are condensed and collected separately with zero reflux. In the second case, simultaneous reaction and distillation processes are carried out. During these experiments, the dynamics of bubble point temperature of the reboiler is recorded and analyzed. From the experimental results it is found that the maximum purity of methyl acetate in instantaneous distillate of reaction followed by distillation and simultaneous reaction and distillation are 0.847 and 0.782, respectively, as analyzed by gas chromatography. From these studies it is found that a batch distillation apparatus itself can be used in certain way to produce the desired product for the case of methyl acetate production by monitoring the temperature regime of the reboiler.

Dye sensitized solar cells have proven its potential as affordable, green method of turning solar energy into electrical energy. This article presents an extensive comparative study on dye sensitized solar cells with two types of transport layers made of ZnO nanorods and TiO2 mesoporous film, wherein bacterial pigment extracted from microorganism Serratia nematodiphila strain B2 is employed as a sensitizer. For performance enhancement via the plasmonic effect, Ag nanoparticles have been deposited onto conducting glass and used as counter electrode (CE). The efficiency and fill factor (averaged over 3 readings) are found to be approximately 2% and 43%, respectively, with TiO2 mesoporous film and 0.4% and 25%, respectively, with ZnO nanorod in the designed DSSCs. Experiments have been conducted with TiO2 film for ten weeks to evaluate the stability of the pigment. The findings suggest that bacterial pigments may possibly replace dyes, creating a new category of solar cells known as biopigment-sensitized solar cells.

Preparation of good quality magnesium oxide from seawater is the most challenging job because the vast majority of undesired impurities come from seawater during the precipitation stage. Hence, the double salt route has been developed as a very unique technique to prepare refractory grade magnesium oxide from seawater. Controlled addition of carrier reagent at the precipitating stage precipitates magnesium as double salt. The double salt is transformed to magnesium carbonate (MgCO3), which after calcination forms magnesium oxide (MgO). The product quality has been established by elemental analysis, PXRD, FTIR, TG/DTG, and FESEM. Commercially available MgCO3 and MgO of HiMedia have also been characterized simultaneously for comparison. The prepared magnesium oxide shows very high purity of 99.75%, which is shown from EDS measurement and PXRD and can be suitable as basic refractory material for industrial purposes.
