| 1 | Dominant mutations in CHK1 cause pronuclear fusion failure and zygote arrest that can be rescued by CHK1 inhibitor显示文摘Dear Editor,Infertility poses a major challenge to human reproductive health,affecting approximately 48 million women worldwide.1 Assisted reproductive techniques(ART),including in vitro fertilization(IVF)and intracytoplasmic sperm injection(ICSI),enable infertile women to have their biological embryos in vitro and further give birth to babies after embryo transfer.However,about 10%of all human embryos produced by ART are blocked in the early embryonic stage2 and approximately 2%fertilized oocytes derived from ART could not accomplish the first cell division.3 About one half of human infertility cases involve an underlying genetic factor,although the majority of genetic causes have remained elusive.4 In this study,we report that dominant mutations in CHK1 are responsible for pronuclear fusion failure and zygote arrest(PFF-ZA)in 7 out of 29 cases,likely through increasing the CHK1 activity.Importantly,PFF-ZA caused by these mutations could be effectively rescued by using the CHK1 inhibitor,PF477736. | Honghui Zhang Tailai Chen Keliang Wu Zhenzhen Hou Shigang Zhao Chuanxin Zhang Yuan Gao Ming Gao Zi-Jiang Chen Han Zhao | 2021 | Cell Research2021，31，7： | 4 |
| 2 | Boosted lithium storage performance by local build-in electric field derived by oxygen vacancies in 3D holey N-doped carbon structure decorated with molybdenum dioxide显示文摘Three-dimensional holey nitrogen-doped carbon matrixes decorated with molybdenum dioxide(MoO_(2))nanoparticles have been successfully synthesized via a NaCl-assisted template strategy.The obtained MoO_(2)/C composites offered multi-advantages,including higher specific surface area,more active sites,more ions/electrons transmission channels,and shorter transmission path due to the synergistic effect of the uniformly distributed MoO_(2) nanoparticles and porous carbon structure.Especially,the oxygen vacancies were introduced into the prepared composites and enhanced the Li^(+)intercalation/deintercalation process during electrochemical cycling by the Coulomb force.The existence of the local built-in electric field was proved by experimental data,differential charge density distribution,and density of states calculation.The uniquely designed structure and introduced oxygen vacancy defects endowed the MoO_(2)/C composites with excellent electrochemical properties.In view of the synergistic effect of the uniquely designed morphology and introduced oxygen vacancy defects,the MoO_(2)/C composites exhibited superior electrochemical performance of a high capacity of 918.2 mAh g^(-1) at 0.1 A g^(-1) after 130 cycles,562.1 mAh g^(-1) at 1.0 A g^(-1) after 1000 cycles,and a capacity of 181.25 mAh g^(-1) even at 20.0 A g^(-1).This strategy highlights the path to promote the commercial application of MoO_(2)-based and other transition metal oxide electrodes for energy storage devices. | Chuanxin Hou Wenyue Yang Hideo Kimura Xiubo Xie Xiaoyu Zhang Xueqin Sun Zhipeng Yu Xiaoyang Yang Yuping Zhang Bin Wang Ben Bin Xu Deepak Sridhar Hassan Algadi Zhanhu Guo Wei Du | 2023 | Journal of Materials Science & Technology2023，，11： | 0 |
| 3 | Neutral color and self-healable electrochromic system based on CuI/Cu and I_(3)^(-)/I^(-)conversions显示文摘The electrochromic(EC)mechanisms of inorganic materials are usually based on reversible cation insertion/extraction or metal deposition/dissolution,which are plagued by ion trapping and dendrite growth,respectively.In this paper,a novel conversion-type electrochromic mechanism is proposed,by making good use of the CuI/Cu redox couple.This CuI-based electrochromic system shows a neutral color switching from transparent and dim grey.By simply increasing the bleaching voltage,I_(3)^(-)/I^(-)redox couple can be further activated.The generated I_(3)^(-)will readily react with Cu,effectively improving the conversion reversibility and thereby rejuvenating the degraded electrochromic performance.Thanks to the well-designed electrode and the self-healing ability,this conversion electrochromic system achieves rapid response times(tcoloring:23 s,tbleaching:6 s),decant optical modulation amplitude(26.4%),high coloration efficiency(86.15 cm^(2)·C^(-1)),admirable cyclic durability(without performance degradation after 480 cycles)and excellent optical memory ability(transmittance variation<1%after 10 h open-circuit storage).The establishment of this conversion-type electrochromism may inspire the exploration of novel electrochromic materials and devices. | Junsen Zhong Bingkun Huang Kunjie Yang Zuju Ma Lingyu Du Ning Luo Fengjiao Tang Chuanxin Hou Fuyi Jiang Litao Kang | 2024 | Nano Research2024，17，5： | 0 |
| 4 | Allelic reprogramming of chromatin states in human early embryos显示文摘The reprogramming of parental epigenomes in human early embryos remains elusive.To what extent the characteristics of parental epigenomes are conserved between humans and mice is currently unknown.Here,we mapped parental haploid epigenomes using human parthenogenetic and androgenetic embryos.Human embryos have a larger portion of genome with parentally specific epigenetic states than mouse embryos.The allelic patterns of epigenetic states for orthologous regions are not conserved between humans and mice.Nevertheless,it is conserved that maternal DNA methylation and paternal H3K27me3 are associated with the repression of two alleles in humans and mice.In addition,for DNA-methylation-dependent imprinting,we report 19 novel imprinted genes and their associated germline differentially methylated regions.Unlike in mice,H3K27me3-dependent imprinting is not observed in human early embryos.Collectively,allele-specific epigenomic reprogramming is different in humans and mice. | Shenli Yuan Lei Gao Wenrong Tao Jianhong Zhan Gang Lu Jingye Zhang Chuanxin Zhang Lizhi Yi Zhenbo Liu Zhenzhen Hou Min Dai Han Zhao Zi-Jiang Chen Jiang Liu Keliang Wu | 2024 | National Science Review2024，11，3： | 0 |
| 5 | Recent advances in the nanoconfinement of Mg-related hydrogen storage materials:A minor review显示文摘Hydrogen is an ideal clean energy because of its high calorific value and abundance of sources.However,storing hydrogen in a compact,inexpensive,and safe manner is the main restriction on the extensive utilization of hydrogen energy.Magnesium(Mg)-based hydrogen storage material is considered a reliable solid hydrogen storage material with the advantages of high hydrogen storage capacity(7.6wt%),good performance,and low cost.However,the high thermodynamic stability and slow kinetics of Mg-based hydrogen storage materials have to be overcome.In this paper,we will review the recent advances in the nanoconfinement of Mg-related hydrogen storage materials by loading Mg particles on different supporting materials,including carbons,metal-organic frameworks,and other materials.Perspectives are also provided for designing high-performance Mg-based materials using nanoconfinement. | Jingjing Zhang Bing Zhang Xiubo Xie Cui Ni Chuanxin Hou Xueqin Sun Xiaoyang Yang Yuping Zhang Hideo Kimura Wei Du | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，1： | 0 |
| 6 | Morphology controllable urchin-shaped bimetallic nickel-cobalt oxide/carbon composites with enhanced electromagnetic wave absorption performance显示文摘The microscopic morphology of electromagnetic wave absorbers influences the multiple reflections of electromagnetic waves and impedance matching,determining the absorption properties.Herein,the urchin-shaped bimetallic nickel-cobalt oxide/carbon(NiCo_(2)O_(4)/C)composites are prepared via a hy-drothermal route,whose absorption properties are investigated by different morphologies regulated by changing calcination temperature.A minimum reflection loss(RL_(min))of-75.26 dB is achieved at a match-ing thickness of 1.5 mm,and the effective absorption bandwidth(EAB)of 8.96 GHz is achieved at 2 mm.Multi-advantages of the synthesized NiCo_(2)O_(4)/C composites contribute to satisfactory absorption proper-ties.First,the interweaving of the needle-like structures increases the opportunities for scattering and multiple reflections of incident electromagnetic waves,and builds up a conductive network to facilitate the enhancement of conductive losses.Second,the carbon component in the NiCo_(2)O_(4)/C composites en-hances the interfacial polarization and reduces the density of the absorber.Besides,generous oxygen va-cancy defects are introduced into the NiCo_(2)O_(4)/C composites,which induces defect polarization and dipole polarization.In summary,the ternary coordination of components,defects and morphology led to out-standing electromagnetic wave absorption,which lightened the path for improving the electromagnetic wave absorption property and enriching the family of NiCo_(2)O_(4) absorbers with excellent performance. | Fushan Li Qiuyu Li Hideo Kimura Xiubo Xie Xiaoyu Zhang Nannan Wu Xueqin Sun Ben Bin Xu Hassan Algadi Rami Adel Pashameah Abdullah K.Alanazi Eman Alzahrani Handong Li Wei Du Zhanhu Guo Chuanxin Hou | 2023 | Journal of Materials Science & Technology2023，，17： | 0 |
| 7 | Initiating Binary Metal Oxides Microcubes Electromagnetic Wave Absorber Toward Ultrabroad Absorption Bandwidth Through Interfacial and Defects Modulation显示文摘Cobalt nickel bimetallic oxides(NiCo_(2)O_(4))have received numerous attentions in terms of their controllable morphology,high temperature,corrosion resistance and strong electromagnetic wave(EMW)absorption capability.However,broadening the absorption bandwidth is still a huge challenge for NiCo_(2)O_(4)-based absorbers.Herein,the unique NiCo_(2)O_(4)@C core-shell microcubes with hollow structures were fabricated via a facile sacrificial template strategy.The concentration of oxygen vacancies and morphologies of the three-dimensional(3D)cubic hollow core-shell NiCo_(2)O_(4)@C framework were effectively optimized by adjusting the calcination temperature.The specially designed 3D framework structure facilitated the multiple reflections of incident electromagnetic waves and provided rich interfaces between multiple components,generating significant interfacial polarization losses.Dipole polarizations induced by oxygen vacancies could further enhance the attenuation ability for the incident EM waves.The optimized NiCo_(2)O_(4)@C hollow microcubes exhibit superior EMW absorption capability with minimum RL(RLmin)of-84.45 dB at 8.4 GHz for the thickness of 3.0 mm.Moreover,ultrabroad effective absorption bandwidth(EAB)as large as 12.48 GHz(5.52-18 GHz)is obtained.This work is believed to illuminate the path to synthesis of high-performance cobalt nickel bimetallic oxides for EMW absorbers with excellent EMW absorption capability,especially in broadening effective absorption bandwidth. | Fushan Li Nannan Wu Hideo Kimura Yuan Wang Ben Bin Xu Ding Wang Yifan Li Hassan Algadi Zhanhu Guo Wei Du Chuanxin Hou | 2023 | Nano-Micro Letters2023，15，12： | 0 |
