He was a protégé of the French philosopher and mathematician Jean Le Rond d'Alembert and took an active part in the preparation of the Encyclopédie.
Nanomaterials can show remarkable tunable properties and play an important role as active components in the preparation of nanoscale electronic, optical, optoelectronic, electrochemical and electromechanical devices [3 7].
In our case countries, UNICEF have played an active role in the preparation of Common Country Assessments (CCA) and UNDAFs advocating children's and women's rights, but it was difficult to track the importance of such plans and processes.
Considering the large number of proteins in the target database, protein structures with known active sites are preferred in the preparation of a target database.
Since biogenic nanoparticles are stabilized 'naturally' in the presence of active biomass, their efficacy in the preparation of heterogeneous catalyst was examined.
In comparison with the transition metal alkoxides such as VTEOS and Ti(OBt 4, the hydrolysis and condensation reactions of zirconium alkoxides (Zr OPrn 4) are too active to be controlled in the preparation of ZrO2/polymer core-shell nanoparticles, although they have shown interesting functional properties and potential applications in many areas[14].
Here, these techniques have been applied to the optimisation of the different steps in the preparation of active titanium silsesquioxane catalysts for the epoxidation of alkenes.
The results indicate that spent catalysts containing high levels of vanadium together with Mo and Ni on Al2O3 can be used in the preparation of active HDM/HDS catalysts, and thereby, their environmental problem can be reduced.
In the present work, the recycling of spent residue hydroprocessing catalysts that contained high levels of vanadium was investigated by using them in the preparation of active new hydrotreating catalyst after subjecting them to different treatments such as decoking, acid-leaching and hydrothermal treatment.
Lignin derivatives have been shown to be effective antioxidants at concentration that are not toxic to normal cells, hence extending their possible application in the preparation of active food packaging material (Nunez-Flores et al. 2013; Ugartondo et al. 2008).
