Xiao Yan,Giri Joshi,Weishu Liu,Yucheng Lan,Hui Wang,Sangyeop Lee,Jack Simonson,S. J. Poon,Terry M. Tritt,Gang Chen,Zhifeng Ren +10 more
TL;DR: Through a nanocomposite approach using ball milling and hot pressing, a peak ZT of 0.8 at 700 °C is achieved, which is about 60% higher than the best reported 0.5 and might be good enough for consideration for waste heat recovery in car exhaust systems.
Journal ArticleDOI
Water splitting by electrolysis at high current densities under 1.6 volts
Haiqing Zhou,Haiqing Zhou,Fang Yu,Fang Yu,Qing Zhu,Jingying Sun,Fan Qin,Luo Yu,Jiming Bao,Ying Yu,Shuo Chen,Zhifeng Ren +11 more
TL;DR: In this paper, an active and durable OER catalyst was used to achieve the commercially required current densities of 500 and 1000 mA cm−2 at 1.586 and 1.657 V, respectively, with very good stability, dramatically lower than any previously reported voltage.
Journal ArticleDOI
Ultrafast room-temperature synthesis of porous S-doped Ni/Fe (oxy)hydroxide electrodes for oxygen evolution catalysis in seawater splitting
Luo Yu,Luo Yu,Libo Wu,Brian McElhenny,Shaowei Song,Dan Luo,Fanghao Zhang,Ying Yu,Shuo Chen,Zhifeng Ren +9 more
TL;DR: In this article, the surface of Ni foam is engineered into a rough S-doped Ni/Fe (oxy)hydroxide layer, which exhibits extraordinary oxygen evolution reaction (OER) performance in both alkaline salty water and seawater electrolytes.
Journal ArticleDOI
Metamaterial-Plasmonic Absorber Structure for High Efficiency Amorphous Silicon Solar Cells
TL;DR: It is shown that a planar structure, consisting of an ultrathin semiconducting layer topped with a solid nanoscopically perforated metallic film and then a dielectric interference film, can highly absorb electromagnetic radiation in the entire visible range, and thus can become a platform for high-efficiency solar cells.
Journal ArticleDOI
Highly stretchable and transparent nanomesh electrodes made by grain boundary lithography
TL;DR: The highly stretchable and transparent Au nanomesh electrodes are promising for applications in foldable photoelectronics and muscle-like transducers.
