    Size-controlled photochemical synthesis of niobium nanoparticles 
    Malyshev, Dimitriy; Bosca Mayans, Francisco; Crites, Charles-Oneil L.; Hallett-Tapley, Geniece L.; Netto-Ferreira, José Carlos; Alarcon, Emilio I.; Scaiano, Juan C. (Royal Society of Chemistry, 2013)
    The size of photochemically-prepared niobium nanoparticles (NbNP) can be controlled by varying the concentration of the photoinitiator in the reaction mixture. The particles, which may be metallic in nature, are readily ...
