Giri Joshi,Hohyun Lee,Yucheng Lan,Xiaowei Wang,Gaohua Zhu,Dezhi Wang,Ryan W. Gould,Diana C. Cuff,Ming Y. Tang,Mildred S. Dresselhaus,Gang Chen,Zhifeng Ren +11 more
TL;DR: A dimensionless thermoelectric figure-of-merit (ZT) of 0.95 in p-type nanostructured bulk silicon germanium (SiGe) alloys is achieved, which is about 90% higher than what is currently used in space flight missions, and half higher than the reported record.
Journal ArticleDOI
Cu nanowires shelled with NiFe layered double hydroxide nanosheets as bifunctional electrocatalysts for overall water splitting
Luo Yu,Luo Yu,Haiqing Zhou,Jingying Sun,Fan Qin,Fang Yu,Jiming Bao,Ying Yu,Shuo Chen,Zhifeng Ren +9 more
TL;DR: In this paper, a facile and scalable approach to fabricate highly efficient three-dimensional (3D) bulk catalysts of core-shell nanostructures, in which few-layer NiFe layered double hydroxide (LDH) nanosheets are grown on Cu nanowire cores supported on Cu foams, toward overall water splitting.
Journal ArticleDOI
Glucose Biosensors Based on Carbon Nanotube Nanoelectrode Ensembles
TL;DR: In this article, a glucose biosensors based on carbon nanotube (CNT) nanoelectrode ensembles (NEEs) was developed for the selective detection of glucose.
Journal ArticleDOI
Hierarchical ZnO Nanostructures
TL;DR: A variety of novel hierarchical nanostructures with 6-, 4-, and 2-fold symmetries have been successfully grown by a vapor transport and condensation technique.
Journal ArticleDOI
Carbon nanotube/carbon fiber hybrid multiscale composites
TL;DR: In this paper, single-fiber composites were fabricated to examine the influence of local nanotube reinforcement on load transfer at the fiber/matrix interface, and the results indicated that the nanocomposite reinforcement improves interfacial load transfer.
