dc.description.abstract	The main objective of this work is to study the superconductivity of nanosize nio bium(Nb). The correlation between the electron-phonon coupling parameter(>.), the Coulomb's pseudopotential(p,*) and the transition temperature at reduced scales is ) determined by using the Mcmillan's strong-coupling theory. Using the 'strong coupling theory', the size dependance of the transition temperature of superconducting nanosize Niobium (Nb) is derived. The expression for transition temperature has been determined and plotted as a function of the electron-phonon coupling parame ter and t~e Coulomb's pseudopotential for superconducting nanosize Niobium. The dependance of the critical temperature (T rameter >. is seen in the graph. c ) with the electron-phonon coupling pa Key words: Mcmillan equation, transition temperature and nanosize Niobium.	en_US
