Thermal Transport in Quasi-1D van der Waals Crystal Ta2Pd3Se8 Nanowires: Size and Length Dependence.
Qian Zhang,Chenhan Liu,Xue Liu,Jinyu Liu,Zhiguang Cui,Yin Zhang,Yin Zhang,Lin Yang,Yang Zhao,Terry T. Xu,Yunfei Chen,Jiang Wei,Zhiqiang Mao,Deyu Li +13 more
TL;DR: The results reveal that partial ballistic phonon transport can persist over 13 μm at room temperature along the molecular chain direction, the longest experimentally observed ballistic transport distance with observable effects on thermal conductivity so far.
Journal ArticleDOI
SiO2-coated porous anodic alumina membranes for high flow rate electroosmotic pumping
Saumitra K. Vajandar,Dongyan Xu,Dmitry A. Markov,John P. Wikswo,William H. Hofmeister,Deyu Li +5 more
TL;DR: In this article, a SiO2-coated porous anodic alumina membrane was used for high flow rate electroosmotic pumping under low applied voltages, achieving a normalized flow rate of 0.125 ml min −1 V −1 cm −2 under a low effective applied voltage of 3 V.
Journal ArticleDOI
Experimental evidence of very long intrinsic phonon mean free path along the c-axis of graphite
TL;DR: In this paper, the average phonon mean free path in the c-axis direction of graphite was shown to be around 200nm at room temperature, much larger than the commonly believed value of just a few nanometers.
Journal ArticleDOI
Cation Dynamics Governed Thermal Properties of Lead Halide Perovskite Nanowires
TL;DR: The underlying mechanisms governing thermal transport in three different kinds of lead halide perovskite nanowires (CH3NH3PbI3, CH3NH 3Pb Br3 and CsPbBr3) are disclosed and their effects should shed light on the design of high-performance MHP based thermal and optoelectronic devices.
Journal ArticleDOI
Phonon Transport through Point Contacts between Graphitic Nanomaterials
Juekuan Yang,Juekuan Yang,Meng Shen,Yang Yang,William J. Evans,Zhiyong Wei,Weiyu Chen,Alfred A. Zinn,Yunfei Chen,Ravi Prasher,Terry T. Xu,Pawel Keblinski,Deyu Li +12 more
TL;DR: In this paper, the authors show that the normalized contact thermal conductance per unit area depends linearly on the tube diameter, which is consistent with an unexpected large phonon mean free path in the $c$-axis direction of graphite, phonon reflection at free surfaces, and phonon focusing in highly anisotropic graphitic materials.
