Journal ArticleDOI
Coaxial silicon nanowires as solar cells and nanoelectronic power sources
Bozhi Tian,Xiaolin Zheng,Thomas J. Kempa,Ying Fang,Nanfang Yu,Guihua Yu,Jinlin Huang,Charles M. Lieber +7 more
TL;DR: These coaxial silicon nanowire photovoltaic elements provide a new nanoscale test bed for studies of photoinduced energy/charge transport and artificial photosynthesis, and might find general usage as elements for powering ultralow-power electronics and diverse nanosystems.
Journal ArticleDOI
Graphene, related two-dimensional crystals, and hybrid systems for energy conversion and storage
Francesco Bonaccorso,Francesco Bonaccorso,Luigi Colombo,Guihua Yu,Meryl D. Stoller,Valentina Tozzini,Andrea C. Ferrari,Rodney S. Ruoff,Vittorio Pellegrini +8 more
TL;DR: Graphene and related two-dimensional crystals and hybrid systems showcase several key properties that can address emerging energy needs, in particular for the ever growing market of portable and wearable energy conversion and storage devices.
Journal ArticleDOI
Solution-processed graphene/MnO2 nanostructured textiles for high-performance electrochemical capacitors.
Guihua Yu,Liangbing Hu,Michael Vosgueritchian,Huiliang Wang,Xing Xie,James R. McDonough,Xu Cui,Yi Cui,Zhenan Bao +8 more
TL;DR: It is demonstrated that solution-exfoliated graphene nanosheets (∼5 nm thickness) can be conformably coated from solution on three-dimensional, porous textiles support structures for high loading of active electrode materials and to facilitate the access of electrolytes to those materials.
Journal ArticleDOI
An ultra-sensitive resistive pressure sensor based on hollow-sphere microstructure induced elasticity in conducting polymer film
Lijia Pan,Alex Chortos,Guihua Yu,Yaqun Wang,Scott G. Isaacson,Ranulfo Allen,Yi Shi,Reinhold H. Dauskardt,Zhenan Bao +8 more
TL;DR: An ultra-sensitive resistive pressure sensor based on an elastic, microstructured conducting polymer thin film that enables the detection of pressures of less than 1Pa and exhibits a short response time, good reproducibility, excellent cycling stability and temperature-stable sensing.
Journal ArticleDOI
Stable Li-ion battery anodes by in-situ polymerization of conducting hydrogel to conformally coat silicon nanoparticles
TL;DR: Infiltration of a conducting polymer hydrogel into Si-based anodes results in a well-connected three-dimensional network structure consisting of Si nanoparticles conformally coated by the conducting polymer, demonstrating a cycle life of 5,000 cycles with over 90% capacity retention at current density.
