Germanium coating boosts lithium uptake in Si nanotube battery anodes
Haro, Marta; Song, Taeseup; Guerrero, Antonio; Bertoluzzi, Luca; Bisquert, Juan; Paik, Ungyu; Garcia-Belmonte, Germà Royal Society of Chemistry (2014)Si nanotubes for reversible alloying reaction with lithium are able to accommodate large volume changes and offer improved cycle retention and reliable response when incorporated into battery anodes. However, Si nanotubes ... -
Modulating the interaction between gold and TiO2 nanowires for enhanced solar driven photoelectrocatalytic hydrogen generation

Quantum Dot Based Heterostructures for Unassisted Photoelectrochemical Hydrogen Generation
Rodenas, Pau; Song, Taeseup; Sudhagar, P.; Marzari, Gabriela; Han, Hyungkyu; Badia Bou, Laura; Gimenez, Sixto; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Bisquert, Juan; Paik, Ungyu; Kang, Yong Soo Wiley (2013-02)TiO2 hollow nanowires (HNWs) and nanoparticles (NPs) constitute promising architectures for QDs sensitized photoanodes for H2 generation. We sensitize these structures with CdS/CdSe quantum dots by two different methods ... -
Three dimensional-TiO2 nanotube array photoanode architectures assembled on a thin hollow nanofibrous backbone and their performance in quantum dot-sensitized solar cells
Han, Hyungkyu; Sudhagar, P.; Song, Taeseup; Jeon, Yeryung; Mora-Sero, Ivan; Fabregat-Santiago, Francisco; Bisquert, Juan; Kang, Yong Soo; Paik, Ungyu Royal Society of Chemistry (2013-02-18)Facile synthesis of TiO2 nanotube branched (length [similar]0.5 μm) thin hollow-nanofibers is reported. The hierarchical three dimensional photoanodes (H-TiO2-NFs) (only [similar]1 μm thick) demonstrate their excellent ...
