Manipulation of Ni Interstitials for Realizing Large Power Factor in TiNiSn‐Based Materials
Wuyang Ren,Wuyang Ren,Hangtian Zhu,Jun Mao,Li You,Li You,Shaowei Song,Tian Tong,Jiming Bao,Jun Luo,Zhiming Wang,Zhifeng Ren +11 more
TL;DR: In this article, an attempt is made to minimize the atomic disorder in order to enhance the carrier mobility, which in turn favors a higher power factor, and significantly enhanced mobility is achieved in the Ni-deficient composition, resulting in peak power factor of ≈50 μW cm−1 K−2, which is comparable to the best n-type halfHeusler compounds.
Journal ArticleDOI
Colloidal Stability of Graphene-Based Amphiphilic Janus Nanosheet Fluid
Dan Luo,Feng Wang,Kamrul Alam,Fang Yu,Ishwar Kumar Mishra,Jiming Bao,Richard C. Willson,Zhifeng Ren +7 more
TL;DR: In this paper, the authors investigated the colloidal stability of graphene-based amphiphilic Janus nanosheets at different salt concentrations and temperatures by developing a theoretical model with an understanding of the chemical and physical properties of the fluid.
Book ChapterDOI
Nanostructured Thermoelectric Materials
Weishu Liu,Zhifeng Ren,Gang Chen +2 more
TL;DR: In this paper, the authors summarized various strategies towards novel nanostructured bulk material with improved ZT value were summarized according to different synthesis routes, including reduced grain size by physical, or chemical powder metallurgy method, surface or interface modification by introduce second phase, and forming precipitations by molten casting method.
Journal ArticleDOI
