Jing Cao,Ying Tze. Sim,Xian Yi Tan,Jie Zheng,Sheau Wei Chien,Ning Jia,Kewei Chen,Yeow Boon Tay,Jinfeng Dong,Le Yang,Hong Kuan Ng,Hongfei Liu,Chee Kiang Ivan Tan,Guofeng Xie,Qiang Zhu,Zibiao Li,Gang Zhang,Lei Hu,Yun Zheng,Jianwei Xu,Qingyu Yan,Xian Jun Loh,Nripan Mathews,Jing Wu,Ady Suwardi +24 more
TL;DR: In this article , the upcycling of silicon from photovoltaic (PV) waste into thermoelectrics is enabled by doping 1% Ge and 4% P, which results in a figure of merit (zT) of 0.45 at 873 K.
Journal ArticleDOI
Designing good compatibility factor in segmented Bi0.5Sb1.5Te3 – GeTe thermoelectrics for high power conversion efficiency
Jing Cao,Xian Yi Tan,Ning Jia,Jie Zheng,Sheau Wei Chien,Hong Kuan Ng,Chee Kiang Ivan Tan,Hongfei Liu,Qiang Zhu,Suxi Wang,Gang Zhang,Kewei Chen,Zibiao Li,Lei Zhang,Jianwei Xu,Lei Hu,Qingyu Yan,Jing Wu,Ady Suwardi +18 more
TL;DR: In this article , the authors report the design and exploration of segmented thermoelectric legs by pairing GeTe with Bi0.5Sb1.5Te3 to achieve extremely high power conversion efficiency of 13.6% between 280 K and 773 K.
Journal ArticleDOI
Fine grains within narrow temperature range by tuning strain-induced boundary migration dominated recrystallization for selective laser melted Inconel 718
TL;DR: In this article , a quasi-in-situ electron backscatter diffraction (EBSD) method was used to study the performance of selective laser melted Inconel 718 (SLM IN718) alloys.
Journal ArticleDOI
Novel method of residual stress reduction for AlSi10Mg manufactured using selective laser melting without compromise of mechanical strength
TL;DR: In this paper , the authors used a lower temperature for treatment followed by uneven cooling, inducing thermal stress during the cooling process such that it cancels out the existing residual stress that remains.
