Abstract:
Nanocrystal quantum dots (NQDs) show great promise in the advancement of the field of photovoltaics. While the maximum efficiency of conventional solar cell (SC) devices is limited to ∼ 31% (Shockley-Queisser limit), devices based on NQDs may attain a maximal thermodynamic efficiency of 42% through the exploitation of multiple exciton generation (MEG). In this process, several electron- hole pairs are created by the absorption of a single high energy photon, as opposed to the single excitons created in conventional solar cell devices.

Abstract:
Grazie all’ingegneria tissutale, branca dell’ingegneria che si occupa della ricostruzione in vitro di tessuti, sta diventando sempre più concreta la possibilità di superare i principali limiti della medicina tradizionale, basata essenzialmente sul trapianto e sui trattamenti farmacologici, soluzioni non sempre praticabili e/o efficaci. Tramite lo studio dei biomateriali e delle loro proprietà è possibile realizzare soluzioni ad hoc per l’ingegneria tissutale di diversi tessuti. Nel caso particolare di questo studio, è stato realizzato mediante elettrofilatura uno scaffold a partire da una blen

Little empirical research has been conducted to discover employers' views of the
