The present work investigates the performance and emission characteristics of hydrous methanol fuelled Homogeneous Charge Compression Ignition (HCCI) engine. In the present work a regular diesel engine has been modified to work as HCCI engine. Hydrous methanol is used with 15% water content in this HCCI engine and its performance and emission behavior is documented. A spark plug is used for ass...

Silica gel loaded with saturated Al(N03)3. 10. H20 solution proved to be an efficient absorbent for the elimination of the interference of fluorine in the microdetermination of carbon and hydrogen in organofluorine compounds. The reagent is cheap, readily available and easily prepared. Three grams are sufficient for 25 determinations. Samples are burnt in a flow of oxygen using the rapid straig...

Nanoparticles of CoGdxFe2 ? xO4 (x = 0%, 25%, 50%) synthesized via sol–gel auto combustion technique and encapsulated within a polymer (Eudragit E100) shell containing curcumin by single emulsion solvent evaporation were formulated in this study. Testing nanoparticles was carried out using different characterization techniques, to investigate composition, crystallinity, size, morphology, surfac...

Cu substituted Ni in Ni0.5-xCuxZn0.5Fe2O4 (x = 0, 0.05, 0.1, 0.15 and 0.2) samples Zn Ni0.5Zn0.5−xCuxFe2O4 is synthesized using the sol-gel auto-combustion process. Recently, we have carried out their structural analysis XRD FTIR found a cubic spinel structure. In this paper, studied morphological compositional structure with help of Scanning Electron Microscope (SEM) attached an Energy Dispers...

In this work, SrCrxFe12-xO19 (x = 0.0, 0.5, 1.0, 1.5) nanostructures were successfully synthesized by sol-gel auto-combustion method, and different aminoacids were used as green reductants. Various analysis results show that SrCrxFe12-xO19 nanoparticles synthesized successfully.The present study shows that SrCrxFe12-xO19 nanoparticle could be used as adsorbent for the desulfurization of liquid ...

This dissertation: (i) develops a novel numerical method for DNS/LES of compressible, turbulent reacting flows, (ii) performs several validation simulations, (iii) studies auto–ignition of a hydrogen vortex ring in air and (iv) studies a hydrogen/air turbulent diffusion flame. The numerical method is spatially non-dissipative, implicit and applicable over a range of Mach numbers. The compressib...

In this study, Aspergillus niger ADM110 fungi was gamma irradiated to produce lipase enzyme and then immobilized onto magnetic barium ferrite nanoparticles (BFN) for biodiesel production. BFN were prepared by the citrate sol-gel auto-combustion method and characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron mic...
