Progress at Business Incubation Centre

• In the 1st Idea lead free piezoelectric ceramics have been prepared b a conventional solid state reaction. In this the incubatee has prepared required ceramics in four different compositions. Further, all the samples have been successfully characterized by SEM.

• In 2nd Idea, CdSe and CdTe nanomaterials have been synthesized and characterized by various instrumental techniques such as XRD, SEM, TEM, UV-Vis. XRD and TEM revealed their size ranges from 26 nm to 41 nm. Their optical band gap is also found to be highly technologically suitable for device fabrication. Furthermore, the study of their photophysical and electrical properties are under progress as a part of future work to study their suitability as ultrabright LED material for the fabrication of device which will be completed by next six months

• Under 3rd Idea, TiO2 has been procured and small area single cell material evaluation and performance checking has been completed. Two 1 x 1 cm cells have been fabricated and tested. The results show Jsc= 21 uA, Voc= 0.4 V, and ?=0.03%. The future plan for this idea is to fabricate large area (10x10cm) which will take place in next three months and finalization of device design and device evaluation will be completed in further three months.

• Data sample forms have been collected by various strata of people for the 4th Idea. Text for different language has been identified and data collection is still under progress. Base line from different text has been estimated. Feature based on the baseline is mapped also.

• Under the 5th Idea, polymer blends have been prepared and characterized well with DSC, AFM and powder XRD. DSC and PXRD results revealed large crystalline property in the solution of blends prepared by the PC and PMMA. Now the study of pore design based on the analysis of pure liquid flow through the pores of a surface microfilter is under progress.

• In 6th Idea, ZnO nanoparticles and hydrogel have been synthesised by a simple techniques and are used on a fabric bandage. The hydrogels have been synthesised using PVA (18 mmol of OH group) with dimethyl suphur oxide DMSO as a solvent and N,N_-methylenebisacrylamide (bis-AAm) as the cross linker. Zinc oxide nanoparticles have also been synthesized using a simple precipitation method with zinc sulfate and ammonia as starting materials. The synthesized samples were calcined at 4000c

• Research and Development Activity, Sharda University Page 19 temperatures for 5 hrs. The hydrogel were utilized to provide uniform distribution and binding of the nanoparticles to the fiber surface and to prevent their agglomeration. The resulting ZnO-Hydrogel fabric bandage have been investigated for antibiotic activity against gram-negative bacteria of three species; E.Coli, Pseudomonas and Staphylococcus aureus known as important pathogens in clinical infections. Significantly high antibacterial effect on the bacteria tested was achieved.

• In 7th Idea, procurement of chemical and glassware has been done. Under this idea, electrodes preparation using graphite and grapheme sheet is under progress.

• In 8th Idea, Chicken bones after calination has been used as heterogeneous solid base catalysts for the direct tranesterification reaction of waste cooking oil. The calcinations of chicken bone was done at 550oC for 2 hours and characterized by XRD and SEM techniques. The transesterification reaction condition was carried out at 60oC for 60 minutes in presence of 0.8 wt % calcined chicken bone powder as catalyst. The yield of the biodiesel was found to be 79.43%. The catalytic activity of various catalysts has been investigated at a molar ratio of 41. The comparative study shows that sulphuric acid, chicken bone, sodium hydroxide and potassium hydroxide produced the following yields of biodiesel 79.16, 77.95, 59.21 and 47.52 % respectively. The acid and saponification values were 0.336 and 72.93 mg KOH/g and lower than the standard values.
