“…An MTS Nanoindenter XP was used to measure the Young's modulus of each film; each indentation was limited to 20% of the porous Si film thickness to avoid substrate interaction effects. 24,25 The porous silicon samples were characterized by high resolution X-ray diffraction and scanning electron mi-z E-mail: monalibjoshi@gmail.com croscopy ͑SEM͒ before and after annealing. Cross section transmission electron microscopy ͑XTEM͒ and AFM ͑40 ϫ 40 m area͒ were used to characterize the silicon nitride film deposited on the porous surface.…”

“…However, to achieve high sensitivity by minimizing effects of the matrix caused by commonly present interfering ions, separation and/or pre concentration procedure is required to be developed prior to the analysis of uranium 3 . Various methods available for pre concentration and separation of uranium are: ion-exchange 20,21 , solid phase extraction (SPE) [22][23][24][25][26] , ion imprinting polymers 27,2922-and cloud point extraction and determination 30,31 liquid-liquid extraction [17][18][19] , Recently, SPE has increasingly been used for pre concentration, separation and removal of trace and ultra-trace amounts of uranium species from complex matrices [32][33][34][35] . Rao et al have presented an overview of the pre concentration techniques used prior to the determination 10 of U +6 .…”

“…The extraction is specific with polyurethane foams having high distribution coefficients. Polyurethane foams have important and fundamental applications in analytical chemistry because of the hydrodynamic properties of polyurethane foams are excellent due to its quasi-spherical membrane structure 35 . It has been reported by several authors that polyurethane foams can be used as effective and inert supports for various extractants and are used for the recovery of metal ions in analytical and water treatment processes.…”
