Title: Thin film – Organic light emitting diode: efficiency and its applications Authors: Sharma, Jitendra Kumar; Tiwari, Sanjay; Jogi, Vivek Kant Abstract: Efficiency is an important factor of any device. Efficiency is a key issue not only for energy consumption, but also for its effect on the longevity of the device, since the ability to operate the device at a lower input power at a given luminance decreases ohmic heating and increases the device lifetime. In this research paper we have taken the basic factors that has been used to calculate the efficiency of Organic Light Emitting Diode around 5%. The efficiency of this device can be increased by using different new techniques in those factors. Page(s): 97-100

Title: Protoplast formation and regeneration of Acetobacter pasteurianum NCIM 2314 Authors: Singhvi, Mamta; Joshi, Dipti; Gokhale, D V Abstract: Method for production and regeneration of <i>Acetobacter pasteurianum </i>NCIM 2314 protoplasts are described. The protoplasts were obtained by treatment with lysozyme in protoplast buffer at pH 8.0 with different osmotic stabilizers. The protoplasts were regenerated on Acetobacter medium with various osmotic stabilizers. Maximum protoplasts formation was obtained in protoplasts buffer with NaC1 as an osmotic stabilizer using lysozyme (0.5mg/mL). Maximum protoplast regeneation was obtained on Acetobacter medium with NaCl (0.5M) as an osmotic stabilizer. The regeneration medium was also applicable to other species of Acetobactor as well. This is, to our knowledge, the first report on protoplast formation and efficient regeneration in case of <i>Acetobacter pasteurianum.</i> Page(s): 94-96

Title: Structural and dielectric studies of [PVA –LiAc] : TiO₂ polymer nano-composite system Authors: Tripathi, Mridula; Trivedi, Shivangi; Upadhyay, Rubi; Pandey, N D; Pandey, K Abstract: An attempt has been made in the present work to prepare Poly Vinyl Alcohol (PVA) based proton conducting gel electrolyte that characterizes them. Nano composite polymer electrolyte consisting of Poly Vinyl Alcohol (PVA), Lithium acetate with TiO₂ filler, is synthesized by the combination of solution cast technique and sol-gel process. Electrically conducting polymer have been most widely accomplished using chemical and electrochemical processing techniques. The composite electrolyte films were characterized by different experimental techniques. The average particle sizes of composite electrolytes were in between 20-30 nm and this system is essentially ionic with maximum conductivity of polymer electrolyte 90[80PVA-20LiAc]:10TiO₂ is [~4.5x10^-6 S/cm] at room temperature. </sub></sub> Page(s): 70-74

Title: Long period fibre grating and its application in the form of glucose sensorial Authors: Tewari, Umesh Abstract: Detection of glucose is carried out by glucose oxidase coated long period fiber grating (LPG) sensor. The coating of enzyme has been achieved through covalent bonding using APTES. Functionalilzed fiber surface poduced measurable shift in resonance wavelength of LPG upon reaction with glucose, which is correlated with changes in the solution refractive index. Page(s): 92-93
