InN32 nanoparticles favour rock salt crystal structure though in bulkInN crystallizes in wurtzite structure. Growth of Nanocrystals in Ionic Liquid Media in collaboration with University of Caen France Discrete nanosized MnAlPO-5 crystals were synthesized by an ionic liquid-mediated approach.The ionic liquid edmimBr as a pore-filling agent directs selectively the synthesis of nanosized MnAlPO-5 crystals without the formation of any side phases. The non-encapsulated ionic liquid in the micropores of AFI nanocrystals can be recovered and reused for several synthesis batches.From an environmental perspectivethis process is extremely beneficial as it can prepare nanosized molecular sieves with a low amount of waste by reuse of the non-reacted reagents.Micro- to macroscopic aspects of the crystallization process of nanosized MnAlPO-5 under ionothermal conditions were also studied.Fully crystallinediscrete nanosized MnAlPO-5 particles grow through a surface-to-core reversed-growth mechanismand the single nanocrystals are finally liberated.This method can be used in designing novel microporous nanocrystals with suitable features for applications in membrane and sensor technologies. Dye-sensitized Solar Cells DSSC in collaboration with Korea Institute of Energy ResearchRepublic of Korea Dye-sensitized solar cells DSSCs are proposed as an alterna- tive to conventional silicon-based solar cells because of their high energy-conversion efficiencies ease of fabrication and low-cost production. We studied the effect of addition of single and binary additives to the electrolyte based on an IL 12-dimethyl-3- propylimidazolium iodide. The best cell performance was observed for electrolytes containing a binary additive mixture of DMAP and CEMI in equal molar ratio and 111 increase in the conversion efficiency from 636 to 7.07 was observed. Similarly the addition of a strong oxidizing agent 3 5-dinitrosalicylic acid to TiO2 paste also enhanced the overall efficiency of DSSC by 10.62. The overall DSC cell efficiency can be enhanced by choosing a suitable material for the blocking layer and optimizing layer forma- tion conditions.
