| 2 | Superior performance and high service stability for Ge Te-based thermoelectric compounds显示文摘GeTe-based compounds have been intensively studied recently due to their superior thermoelectric performance,but their real applications are still limited so far due to the drastic volume variation that occurs during the rhombohedral–cubic phase transition,which may break the material or the material/electrode interface during service.Here,superior performance and high service stability for GeTe-based thermoelectric compounds are achieved by co-doping Mg and Sb into GeTe.The linear coefficient of thermal expansion before phase transition is greatly improved to match that after phase transition,yielding smooth volume variation around the phase transition temperature.Likewise,co-doping(Mg,Sb)in GeTe successfully tunes the carrier concentration to the optimal range and effectively suppresses the lattice thermal conductivity.A peak z T of 1.84 at 800 K and an average z T of 1.2 in 300–800 K have been achieved in Ge0.85Mg0.05Sb0.1Te.Finally,a Ni/Ti/Ge0.85Mg0.05Sb0.1Te thermoelectric uni-leg is fabricated and tested,showing quite good service stability even after 450 thermal cycles between 473 K and 800 K.This study will accelerate the application of GeTe-based compounds for power generation in the mid-temperature range. | Tong Xing Qingfeng Song Pengfei Qiu Qihao Zhang Xugui Xia Jincheng Liao Ruiheng Liu Hui Huang Jiong Yang Shengqiang Bai Dudi Ren Xun Shi Lidong Chen | 2019 | National Science Review2019，6，5： | 4 |

| 4 | Thermoelectric Transport Properties of R_yFe_3NiSb_(12)(R=Ba,Nd and Yb)显示文摘To evaluate the influence of Ni substitution on electrical transport properties, the thermoelectric transport properties of the p-type skutterudites R y Fe3 Ni Sb12(R = Ba, Nd and Yb) are systematically investigated from2.5 K to 800 K. By carefully modifying the filling fractions of the three fillers, Ba, Nd and Yb, the carrier concentration is precisely adjusted, which changes proportionally to the nominal value calculated by valence counting rule. The carrier concentration dependences of mobility and Seebeck coefficient represent two band contribution in the valence band, and the optimized carrier concentration for thermoelectric performance is between(5-9) 1020cm3. The lattice thermal conductivity of samples filled with rare-earth elements(Nd and Yb) are significantly lower as compared to Ba-filled, due to the lower resonant frequency and partial filling. Compared with Co substitution, Ni substitution tends to close the band gap, which results in heavier bipolar diffusion at high temperature for R y Fe3 Ni Sb12. However, due to the enhancement of the density of state, when the carrier concentrations are similar, R y Fe3 Ni Sb12possess higher thermal power and thus higher power factor than R y Fe2Co2Sb12 in the lower temperature range. A ZT value of 0.73 is obtained for Yb0.77Fe3 Ni Sb12at 600 K. | Ruiheng Liu Jung Young Cho Jiong Yang Wenqing Zhang Lidong Chen | 2014 | Journal of Materials Science & Technology2014，30，11： | 0 |
| 5 | 3D collagen matrices modulate the transcriptional trajectory of bone marrow hematopoietic progenitors into macrophage lineage commitment显示文摘Physical signals provided by the extracellular matrix(ECM)are key microenvironmental parameters for the fate decision of hematopoietic stem and progenitor cells(HSPC)in bone marrow.Insights into cell-ECM interactions are critical for advancing HSC-based tissue engineering.Herein,we employed collagen hydrogels and collagen-alginate hydrogels of defined stiffness to study the behaviors of hematopoietic progenitor cells(HPCs).Three-dimensional(3D)collagen hydrogels with a stiffness of 45 Pa were found to promote HPC maintenance and colony formation of monocyte/macrophage progenitors.Using single-cell RNA sequencing(scRNA-seq),we also characterized the comprehensive transcriptional profiles of cells randomly selected from two-dimensional(2D)and 3D hydrogels.A distinct maturation trajectory from HPCs into macrophages within the 3D microenvironment was revealed by these results.3D-derived macrophages expressed high levels of various cytokines and chemokines,such as Saa3,Cxcl2,Socs3 and Tnf.Furthermore,enhanced communication between 3D-macrophages and other hematopoietic clusters based on ligand-repair interactions was demonstrated through bioinformatic analyses.Our research underlines the regulatory role of matrix-dimensionality in HPC differentiation and therefore probably be applied to the generation of specialized macrophages. | Pan Zhang Linmu Xu Jingsong Gao Guangkui Xu Yanping Song Guang Li Jingjing Ren Yunjie Zhang Cheng Yang Yu Zhang Ruiheng Xie Nu Zhang Hui Yang | 2022 | Bioactive Materials2022，7，4： | 0 |
| 6 | Sinusoidally architected helicoidal composites inspired by the dactyl club of mantis shrimp显示文摘The impact region of the dactyl club of mantis shrimp features a rare sinusoidally helicoidal architecture,contributing to its efficient impact-resistant characteristics.This study aims to attain bioinspired sinusoidally architected composites from a practical engineering way.Morphological features of plain-woven fabric were characterized,which demonstrated that the interweaving warp and weft yarns exhibited a sinusoidal architecture.Interconnected woven composites were thus employed and helicoidally stacked to achieve the desired structure.Quasi-static three-point bending and low-velocity impact tests were subsequently performed to evaluate their mechanical performance.Under three-point bending condi-tion,the dominant failure mode gradually changed from fiber breakage to delamination with the increase in the pitch angle.Failure displacement and energy absorption of the heli-coidal woven composites were,respectively,43.89%and 141.90%greater than the unidirectional ones.Under low-velo-city impact condition,the damage area of the helicoidal woven composites decreased by 49.66%while the residual strength increased by 10.10%compared with those of the unidirectional ones,exhibiting better damage resistance and tolerance.Also,effects of fiber architecture on mechanical properties were examined.This work will shed light on future design of the next-generation impact-resistant architected composites. | Ruiheng Yang Huitian Wang Bing Wang Sheng Zhang Zhiping Huang Sha Yin | 2023 | International Journal of Smart and Nano Materials2023，14，3： | 0 |
| 7 | Achieving 20% photovoltaic efficiency by manganese doped methylammonium lead halide perovskites显示文摘We report a transition metal such as manganese doped methylammonium lead halide perovskite(MA(Pb:Mn)I_(3)) solar cell with an power conversion efficiency(PCE) over 20%. The rational design and fabrication of MA(Pb:Mn)I3 lead to the enhancements of all the photovoltaic parameters. To incorporate Mn can effectively eliminate the trap-assist and bi-molecular recombination. The photo-absorption ability at shorter wavelengths(i.e., less than 500 nm) and charge carrier lifetime can be elaborated. More importantly, the existence of the Mn^(2+)-I~--Mn^(3+)motif contributes for the double exchange effect, giving rise to the charge/spin transport. By a combination of linearly and circularly polarized photo-excitations, we have explicitly determined the role of intrinsic spin–orbit coupling(SOC) in MA(Pb:Mn)I_(3). More dark states are expected to be available for the photocurrent generation. This study may pave the way for deep understandings of transition metals doped hybrid perovskites for highly efficient solar cell applications. | Liangliang Deng Hanjun Yang Ruiheng Pan Haomiao Yu Jinpeng Li Ling Xu Kai Wang | 2021 | Journal of Energy Chemistry2021，30，9： | 0 |
