1Analgesic effect of different moxibustion durations in rheumatoid arthritis rats显示文摘OBJECTIVE:To observe the influence of different moxibustion durations on hypothalamic pro-opiomelanocortin(POMC)and prodynorphin(PDYN)mRNA expressions and plasmaβ-endorphin(β-EP)content in rheumatoid arthritis(RA)rats,to understand the mechanism of moxibustion analgesia and its dose-effect relationship.METHODS:Twelve male Wistar rats were randomly selected from 48 male Wistar rats as a normal control group.The RA model was created by raising rats in a windy(blowing with electric fan),cold(6℃±2℃),and wet(80%-90%humidity)environment for 20 days,12 h each day.This was followed byinjectionofFreund'scompleteadjuvant(0.15 mL)into the ankle.Then,rats were randomly divided into a model group,moxibustion groupⅠ,and moxibustion groupⅡ,with 12 rats in each group.In moxibustion groupsⅠandⅡ,moxibustion was given at Shenshu(BL 23)and Zusanli(ST 36)for 20and 40 min,respectively,once daily for 15 days.Hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content were determined.RESULTS:Compared with the normal group,the pressure pain threshold decreased,while the hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content increased in the moxibustion groups(P<0.01).Compared with the model group,the pressure pain threshold,hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content in the moxibustion groups increased significantly(P<0.01).Compared the moxibustion groupⅠ,the pain threshold,hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content in moxibustion groupⅡsignificantly increased(P<0.01).CONCLUSION:Moxibustion has an analgesic effect and increases hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content inRArats.TheanalgesiceffectinmoxibustiongroupⅡisbetterthanthatinmoxibustiongroupⅠ.Baozhu Zheng Ling Hu Xiaoge Song ZijianWu Ronglin Cai Lu He Cheng Zhang QingYu 2014Journal of Traditional Chinese Medicine2014,34,1:10
2The construction of a genetic linkage map of non-heading Chinese cabbage (Brassica campestris ssp.chinensis Makino)显示文摘Non-heading Chinese cabbage(Brassica campestris ssp.chinensis Makino) is one of the most important vegetables in eastern China.A genetic linkage map was constructed using 127 doubled haploid(DH) lines,and the DH population was derived from a commercial hybrid 'Hanxiao'(lines SW-13 × L-118).Out of the 614 polymorphic markers,43.49% were not assigned to any of the linkage groups(LGs).Chi-square tests showed that 42.67% markers were distorted from expected Mendelian segregation ratios,and the direction of distorted segregation was mainly toward the paternal parent L-118.After sequentially removing the markers that had an interval distance smaller than 1 cM from the upper marker,the overall quality of the linkage map was increased.Two hundred and sixty-eight molecular markers were mapped into 10 LGs,which were anchored to the corresponding chromosome of the B.rapa reference map based on common simple sequence repeat(SSR) markers.The map covers 973.38 cM of the genome and the average interval distance between markers was 3.63 cM.The number of markers on each LG ranged from 18(R08) to 64(R07),with an average interval distance within a single LG from 1.70 cM(R07) to 6.71 cM(R06).Among these mapped markers,169 were sequence-related amplified polymorphism(SRAP) mo-lecular markers,50 were SSR markers and 49 were random amplification polymorphic DNA(RAPD) markers.With further saturation to the LG,the current map offers a genetic tool for loci analysis for important agronomic traits.Yan Cheng Jianfeng Geng Jingyi Zhang Qian Wang Qingyu Ban Xilin Hou 2009Journal of Genetics and Genomics2009,36,8:9
3Influences of accumulated mileage and technological changes on emissions of regulated pollutants from gasoline passenger vehicles显示文摘In this study, the influences of accumulated mileage(deterioration) and technological changes(emission standards) on emission factors(EFs) of regulated pollutants(CO, HC, and NO_x) from gasoline passenger vehicles were investigated based on Inspection and Maintenance(I/M) data using the chassis dynamometer method. The accumulated mileage of passenger vehicles was significantly linearly correlated with vehicle age. For most cases,the average EFs of CO, HC and NO_x were significantly linearly correlated with accumulated mileage, indicating that emission deterioration had a significant impact on pollutant EFs.Implemented emission standards markedly influenced the EFs of regulated pollutants, and EFs markedly decreased with progressing emission standards. The present study also compared EFs of regulated pollutants between this study and the International vehicle emission(IVE) model, and marked differences in EFs were seen with variations in emission standards, vehicle types and accumulated mileage; NO_x EFs in this study were higher than in the IVE model. The results provide new insight into estimating regulated pollutant emissions using the IVE model.Qingyu Zhang Juwang Fan Weidong Yang Fang Ying Zhen Bao Yi Sheng Cheng Lin Xuan Chen 2018Journal of Environmental Sciences2018,30,9:5
4Rational development of a human antibody cocktail that deploys multiple functions to confer Pan-SARS-CoVs protection显示文摘Structural principles underlying the composition and synergistic mechanisms of protective monoclonal antibody cocktails are poorly defined.Here,we exploited antibody cooperativity to develop a therapeutic antibody cocktail against SARS-CoV-2.On the basis of our previously identified humanized cross-neutralizing antibody H014,we systematically an a lyzed a fully human n aive antibody library and rationally identified a potent neutralizing antibody partner,P17,which confers effective protection in animal model.Cryo-EM studies dissected the nature of the P17 epitope,which is SARS-CoV-2 specific and distinctly different from that of HOI4.High-resolution structure of the SARS-CoV-2 spike in complex with HOM and P17,together with functional investigations revealed that in a two-antibody cocktail,synergistic neutralization was achieved by S1 shielding and conformational locking,thereby blocking receptor attachment and viral membrane fusion,conferring high potency as well as robustness against viral mutation escape.Furthermore,cluster analysis identified a hypothetical 3rd antibody partner for further reinforcing the cocktail as pan-SARS-CoVs therapeutics.Hangping Yao Yao Sun Yong-Qiang Deng Nan Wang Yongcong Tan Na-Na Zhang Xiao-Feng Li Chao Kong Yan-Peng Xuc Qi Chen Tian-Shu Cao Hui Zhao Xintian Yan Lei Cao Zhe Lv Dandan Zhu Rui Feng Nanping Wu Wenhai Zhang Yuhao Hu Keda Chen Rong-Rong Zhang Qingyu Lv Shihui Sun Yunhua Zhou Run Yan Guan Yang Xinglu Chanjuan Liu Xiangyun Lu Linfang Cheng Hongying Qiu Xing-Yao Huang Tianhao Weng Danrong Shi Weidong Jiang Junbin Shao Lei Wang Jie Zhang Tao Jiang Guojun Lang Cheng-Feng Qinc Lanjuan Li Xiangxi Wang 2021Cell Research2021,31,1:5
5Effect of sulfate-reducing bacteria on corrosion of X80 pipeline steel under disbonded coating in a red soil solution显示文摘Effect of sulfate-reducing bacteria on the corrosion behaviors of API-X80 pipeline steel has been studied in crevices under simulated disbonded coatings in red soil solution.The results show that there are amounts of SRB in the crevice under the simulated disbonded coating in the red soil solution during the whole period of experiment.The electrochemical impedance spectroscopy shows that SRB can enhance the corrosion of the steel in the crevice under the simulated disbonded coating,and the thermodynamic analyses indicate that SRB can accelerate the corrosion of steel using not only sulfate but also ferric hydroxide as electron acceptors.Boxin Wei Jin Xu Qi Fua Qingyu Qin Yunlong Bai Cheng Sun Chuan Wang Zhenyao Wang Wei Ke 2021Journal of Materials Science & Technology2021,,28:4
6Intrinsic mode characteristic analysis and extraction in underwater cylindrical shell acoustic radiation显示文摘Target dimension is important information in underwater target classification. An intrinsic mode characteristic extraction method in underwater cylindrical shell acoustic radiation was studied in this paper based on the mechanism of shell vibration to gain the information about its dimension instead of accurate inversion processing. The underwater cylindrical shell vibration and acoustic radiation were first analyzed using mode decomposition to solve the wave equation. The characteristic of acoustic radiation was studied with different cylindrical shell lengths, radii, thickness, excitation points and fine structures. Simulation results show that the intrinsic mode in acoustic radiation spectrum correlates closely with the geometry dimensions of cylindrical shells. Through multifaceted analysis, the strongest intrinsic mode characteristic extracted from underwater shell acoustic radiated signal was most likely relevant to the radiated source radius. Then, partial information about unknown source dimension could be gained from intrinsic mode characteristic in passive sonar applications for underwater target classification. Experimental data processing results verified the effectiveness of the method in this paper.LIU QingYu FANG ShiLiang CHENG Qiang CAO Jin AN Liang LUO XinWei 2013Science China(Physics,Mechanics & Astronomy)2013,56,7:3
7Interleukin-25 in sputum as a marker of airway inflammation in children asthma显示文摘Dear Editor,Interleukin-25(IL-25,also called IL-17E)is an important IL-17 family member that helps initialize and regulate type 2 immunity,exerting an important influence on the pathogenesis of asthma(Corrigan et al.,2011;Barlow et al.,2012).Furthermore,it plays a vital role in initiating type 2 innate lymphoid cell activation and maintenance(Tong and Li,2018)and inducing Th2-type cytokine-mediated allergic airway eosinophilia(Morita et al.,2015).IL-25 expression increases in patients with asthma in different types of lung cells,including lung structural cells(such as endothelium and airway epithelium),eosinophils,T-cells,and mast cells.Following allergen exposure,cells in the bronchial submucosa increase and secrete or respond to IL-25(Corrigan et al.,2011).Plasma IL-25 levels increase in patients with asthma and correlate with lung function(Cheng et al.,2014).The association between IL-25 cells and pulmonary function indicates that IL-25 could be used to monitor asthma severity.In some mouse models,epithelial IL-25 cytokines are closely related with a range of airway inflammation modalities,including type 2 cytokine production,airway eosinophil inflammation,mucinous epithelial metaplasia,and airway hyperresponsiveness(AHR)(Suzukawa et al.,2012).Yun Zhang Cuifen Zhao Xiuxia Zhao Qingyu Kong Mingjie Dingi Yuling Han Xiang Ma Lu Cheng 2019Science China(Life Sciences)2019,62,12:3
8Standard pancreatoduodenectomy versus extended pancreatoduodenectomy with modified retroperitoneal nerve resection in patients with pancreatic head cancer:a multicenter randomized controlled trial显示文摘Background:The extent of pancreatoduodenectomy for pancreatic head cancer remains controversial,and more high-level clinical evidence is needed.This study aimed to evaluate the outcome of extended pancreatoduodenectomy(EPD)with retroperitoneal nerve resection in pancreatic head cancer.Methods:This multicenter randomized trial was performed at 6 Chinese highvolume hospitals that enrolled patients between October 3,2012,and September 21,2017.Four hundred patients with stage I or II pancreatic head cancer and without specific pancreatic cancer treatments(preoperative chemotherapy or chemoradiation)within three months were randomly assigned to undergo standard pancreatoduodenectomy(SPD)or EPD,with the latter followed by dissection of additional lymph nodes(LNs),nerves and soft tissues 270◦on the right side surrounding the superior mesenteric artery and celiac axis.The primary endpoint was overall survival(OS)by intention-to-treat(ITT).The secondary endpoints were disease-free survival(DFS),mortality,morbidity,and postoperative pain intensity.Results:TheR1 ratewas slightly lower with EPD(8.46%)thanwith SPD(12.56%).The morbidity and mortality rates were similar between the two groups.The median OS was similar in the EPD and SPD groups by ITT in the whole study cohort(23.0 vs.20.2 months,P=0.100),while the median DFS was superior in the EPD group(16.1 vs.13.2 months,P=0.031).Patients with preoperative CA19–9<200.0 U/mL had significantly improved OS and DFS with EPD(EPD vs.SPD,30.8 vs.20.9 months,P=0.009;23.4 vs.13.5 months,P<0.001).The EPD group exhibited significantly lower locoregional(16.48%vs.35.20%,P<0.001)andmesenteric LNrecurrence rates(3.98%vs.10.06%,P=0.022).The EPD group exhibited less back pain 6 months postoperation than the SPD group.Conclusions:EPD for pancreatic head cancer did not significantly improve OS,but patients with EPD treatment had significantly improved DFS.In the subgroup analysis,improvements in bothOS and DFS in the EPD armwere observed in patients with preoperative CA19–9<200.0 U/mL.EPD could be used as an effective surgical procedure for patients with pancreatic head cancer,especially those with preoperative CA19–9<200.0 U/mL.Qing Lin Shangyou Zheng Xianjun Yu Meifu Chen Yu Zhou Quanbo Zhou Chonghui Hu Jing Gu Zhongdong Xu LinWang Yimin Liu Qingyu Liu MinWang Guolin Li He Cheng Dongkai Zhou Guodong Liu Zhiqiang Fu Yu Long Yixiong Li Weilin Wang Renyi Qin Zhihua Li Rufu Chen 2023Cancer Communications2023,43,2:3
9Effect of the processing route on the microstructure and mechanical behavior of superlight Mg-9Li-1Zn alloy via friction stir processing显示文摘In this study, the effect of the processing route using a friction stir processing(FSP) method on the microstructure and mechanical behavior of a Mg-9Li-1Zn alloy was systematically investigated. In the FSP method, the odd-numbered(1st and 3rd) process directions and even-numbered(2nd and 4th) passes were alternated to distribute the strain throughout the whole processed zone uniformly. Consequently, the processed zone had a much more uniform microstructure and hardness distribution than the processed zone obtained using the conventional FSP method. Using this method, the grain size of a Mg-9Li-1Zn sheet alloy was refined from ~31 μm to ~0.21 μm with uniformly distributedα and β phases. The processed alloy exhibited a high strength-ductility synergy with an ultimate tensile strength(UTS) of 220.1 MPa and total elongation of 70.0% at a strain rate of 10^(-3)s^(-1), overwhelmingly higher than those of the base metal, 155.6 MPa in UTS and 36.0%in elongation. The in-situ SEM-DIC analysis and TEM observation demonstrated that such an outstanding ductility with moderate strength is caused by grain boundary sliding, the dominant deformation mechanism of the ultra-fine-grained sample after FSP. The processing route with reverse processing direction was proven to be efficient in producing the ultrafine grain size microstructure and improving the mechanical properties of superlight Mg-9Li-1Zn alloy.Mengran Zhou Zhuoran Zeng Chun Cheng Yoshiaki Morisada Qingyu Shi Jian-Yih Wang Hidetoshi Fujii 2022Journal of Magnesium and Alloys2022,10,11:2
10Mutagenesis reveals that the rice OsMPT3 gene is an important osmotic regulatory factor显示文摘Plant mitochondrial phosphate transporters regulate phosphate transport and ATP synthesis. Determining whether they function in abiotic stress response process would shed light on their response to salt stress. We used the CRISPR/Cas9 gene-editing system to mutagenize two mitochondrial phosphate transporters, OsMPT3;1 and OsMPT3;2, to investigate their regulatory roles under salt stress. Two cas9(CRISPR-associated protein9)-free homozygous mutants, mpt33 and mpt30, were confirmed to be stable. Both OsMPT3;1 and OsMPT3;2 were markedly induced by salt stress, and their mutagenesis strongly inhibited growth and development, especially under salt stress. Mutagenesis sharply reduced the accumulation of ATP, phosphate, calcium, soluble sugar, and proline and increased osmotic potential, malondialdehyde, and Na^+ /K^+ ratio under salt stress. Both mutants demonstrate normal growth and development in the presence of ATP, revealing high sensitivity to exogenous ATP under salt stress. The mutants showed lowered rates of Na^+ efflux but also of K^+ and Ca^(2+) influx under salt stress. Mutagenesis of OsMPT3;2 altered the enrichment profiles of differentially expressed genes involved mainly in synthesis of secondary metabolites, metabolism of glycolysis, pyruvate, tricarboxylic acid cycle, in response to salt stress. The mutant displayed significant accumulation differences in 14 metabolites involved in 17 metabolic pathways, and strongly up-regulated the accumulation of glutamine, a precursor in proline synthesis, under salt stress. These findings suggest that the OsMPT3 gene modulates phosphate transport and energy supply for ATP synthesis and triggers changes in accumulation of ions and metabolites participating in osmotic regulation in rice under salt stress, thus increasing rice salt tolerance. This study demonstrates the effective application of CRISPR/Cas9 gene-editing to the investigation of plant functional genes.Shengcai Huang Shichao Xin Guoqiang Xie Jiao Han Zhonglai Liu Bing Wang Shuqing Zhang Qingyu Wu Xianguo Cheng 2020The Crop Journal2020,8,3:2
11Observation of an anti-cyclonic mesoscale eddy in the subtropical northwestern Pacific Ocean from altimetry and Argo profiling floats显示文摘The comprehensive three-dimensional structures of an anti-cyclonic mesoscale eddy(AE)in the subtropical northwestern Pacific Ocean were investigated by combining the Argo floats profiles with enhanced vertical and temporal sampling and satellite altimetry data.The AE originated near the Kuroshio Extension and then propagated westward with mean velocity of 8.9 cm/s.Significant changes and evolutions during the AE’s growing stage(T1)and further growing stage(T2)were revealed through composite analysis.In the composite eddy core,maximum temperature(T)and salinity(S)anomalies were of 1.7(1.9)℃ and 0.04(0.07)psu in T1(T2)period,respectively.The composite T anomalies showed positive in almost whole depth,but the S anomalies exhibited a sandwich-like pattern.The eddy’s intensification and its influence on the intermediate ocean became more significant during its growth.The trapping depth increased from 400×10^4 Pa to 580×10^4 Pa while it was growing up,which means more water volume,heat and salt content in deeper layers can be transported.The AE was strongly nonlinear in upper oceans and can yield a typical mean volume transport of 0.17×10^6 m^3/s and a mean heat and salt transport anomaly of 3.6×10^11 W and–2.1×10^3 kg/s during the observation period.The Energy analysis showed that eddy potential and kinetic energy increased notably as it propagated westward and the baroclinic instability is the major energy source of the eddy growth.The variation of the remained Argo float trapped within the eddy indicated significant water advection during the eddy’s propagation.Yang Wang Cheng Li Qingyu Liu 2020Acta Oceanologica Sinica2020,39,7:2

15Hetero-bivalent nanobodies provide broad-spectrum protection against SARS-CoV-2 variants of concern including Omicron显示文摘SARS-CoV-2 variants with adaptive mutations have continued to emerge,causing fresh waves of infection even amongst vaccinated population.The development of broad-spectrum antivirals is thus urgently needed.We previously developed two hetero-bivalent nanobodies(Nbs),aRBD-2-5 and aRBD-2-7,with potent neutralization activity against the wild-type(WT)Wuhan isolated SARS-CoV-2,by fusing aRBD-2 with aRBD-5 and aRBD-7,respectively.Here,we resolved the crystal structures of these Nbs in complex with the receptor-binding domain(RBD)of the spike protein,and found that aRBD-2 contacts with highly conserved RBD residues and retains binding to the RBD of the Alpha,Beta,Gamma,Delta,Delta plus,Kappa,Lambda,Omicron BA.1,and BA.2 variants.In contrast,aRBD-5 and aRBD-7 bind to less conserved RBD epitopes non overlapping with the epitope of aRBD 2,and do not show apparent binding to the RBD of some variants.However,when fused with aRBD-2,they effectively enhance the overal binding affinity.Consistently,aRBD-2-5-Fc and aRBD-2-7 Fc potently neutralized all of the tested authentic or pseudotyped viruses,incuding WT,Alpha,Beta,Gamma,Delta,and Omicron BA.1,BA.1.1 and BA.2.Furthermore,aRBD-2-5-FC provided prophylactic protection against the WT and mouse-adapted SARS CoV-2 in mice,and conferred protection against the Omicron BA.1 variant in hamsters prophylatically and therapeutically,indicating that aRBD-2-5-Fc could potentially beneft the prevention and treatment of COVID-19 caused by the emerging variants of concern.Our strategy provides new solutions in the development of broad-spectrum therapeutic antibodies for COVID-19.Huan Ma Xinghai Zhang Peiyi Zheng Peter H.Dube Weihong Zeng Shaohong Chen Qingyu Cheng Yunru Yang Yan Wu Junhui Zhou Xiaowen Hu Yan Xiang Huajun Zhang Sandra Chiu Tengchuan Jin 2022Cell Research2022,32,9:1

17Tomato expressing Arabidopsis glutaredoxin gene AtGRXS17 confers tolerance to chilling stress via modulating cold responsive components显示文摘Chilling stress is a production constraint of tomato,a tropical origin,chilling-sensitive horticultural crop.The development of chilling tolerant tomato thus has significant potential to impact tomato production.Glutaredoxins(GRXs)are ubiquitous oxidoreductases,which utilize the reducing power of glutathione to reduce disulfide bonds of substrate proteins and maintain cellular redox homeostasis.Here,we report that tomato expressing Arabidopsis GRX gene AtGRXS17 conferred tolerance to chilling stress without adverse effects on growth and development.AtGRXS17-expressing tomato plants displayed lower ion leakage,higher maximal photochemical efficiency of photosystem II(Fv/Fm)and increased accumulation of soluble sugar compared with wild-type plants after the chilling stress challenge.Furthermore,chilling tolerance was correlated with increased antioxidant enzyme activities and reduced H2O2 accumulation.At the same time,temporal expression patterns of the endogenous C-repeat/DRE-binding factor 1(SlCBF1)and CBF mediated-cold regulated genes were not altered in AtGRXS17-expressing plants when compared with wild-type plants,and proline concentrations remained unchanged relative to wild-type plants under chilling stress.Green fluorescent protein-AtGRXS17 fusion proteins,which were initially localized in the cytoplasm,migrated into the nucleus during chilling stress,reflecting a possible role of AtGRXS17 in nuclear signaling of chilling stress responses.Together,our findings demonstrate that genetically engineered tomato plants expressing AtGRXS17 can enhance chilling tolerance and suggest a genetic engineering strategy to improve chilling tolerance without yield penalty across different crop species.Ying Hu Qingyu Wu Stuart A Sprague Jungeun Park Myungmin Oh C B Rajashekar Hisashi Koiwa Paul A Nakata Ninghui Cheng Kendal D Hirschi Frank F White Sunghun Park 2015Horticulture Research2015,2,1:1

19Genome assembly and transcriptome analysis provide insights into the antischistosome mechanism of Microtus fortis显示文摘Microtus fortis is the only mammalian host that exhibits intrinsic resistance against Schistosoma japonicum infection.However,the underlying molecular mechanisms of this resistance are not yet known.Here,we perform the first de novo genome assembly of M.fortis,comprehensive gene annotation analysis,and evolution analysis.Furthermore,we compare the recovery rate of schistosomes,pathological changes,and liver transcriptomes between M.fortis and mice at different time points after infection.We observe that the time and type of immune response in M.fortis are different from those in mice.M.fortis activates immune and inflammatory responses on the 10th day post infection,such as leukocyte extravasation,antibody activation,Fc-gamma receptor-mediated phagocytosis,and the interferon signaling cascade,which play important roles in preventing the development of schistosomes.In contrast,an intense immune response occurrs in mice at the late stages of infection and could not eliminate schistosomes.Infected mice suffer severe pathological injury and continuous decreases in cell cycle,lipid metabolism,and other functions.Our findings offer new insights into the intrinsic resistance mechanism of M.fortis against schistosome infection.The genome sequence also provides the basis for future studies of other important traits in M.fortis.Hong Li Zhen Wang Shumei Chai Xiong Bai Guohui Ding Yuanyuan Li Junyi Li Qingyu Xiao Benpeng Miao Weili Lin Jie Feng Mingyue Huang Cheng Gao Bin Li Wei Hu Jiaojiao Lin Zhiqiang Fu Jianyun Xie Yixue Li 2020Journal of Genetics and Genomics2020,47,12:1
20Thermoelectric Transport Properties of TmAg_(x)Cu_(1-x)Te_(2) solid solutions显示文摘Intrinsic partial occupation of Cu induces strong phonon scattering for an extremely low lattice thermal conductivity in TmCuTe_(2),which leads this material to be a promising candidate for thermoelectric applications.This work focus on the electronic and phononic transport properties of TmCuTe_(2) with Agalloying on the Cu site.Such a Ag/Cu substitution is found to enable a decrease in Hall carrier concentration from 141019 to 81019 cm^(3) for an evaluation of the charge transport based on a single parabolic band(SPB)model with acoustic scattering.In addition,Ag-substitution simultaneously introduces Cu/Ag point defects for extra phonon scattering,leading the lattice thermal conductivity to be as low as~0.25 W/m-K in a broad temperature.The optimization in carrier concentration and the reduction in lattice thermal conductivity contribute to a~40%improvement in average thermoelectric figure of merit(zT).The determination of band parameters enables a guidance for further advancements in this promising thermoelectric material.Qingyu Bai Xinyue Zhang Bing Shan Xuemin Shi Cheng Sun Siqi Lin Wen Li Yanzhong Pei 2021Journal of Materiomics2021,7,4:0
