| 1 | Nuclear miR-665 aggravates heart failure via suppressing phosphatase and tensin homolog transcription显示文摘Although numerous miRNAs have been discovered,their functions in the different subcellular organelles have remained obscure.In this study,we found that miR-665 was enriched in the nucleus of cardiomyocytes,and then investigated the underlying role of nuclear miR-665 in heart failure.RNA fluorescence in situ hybridization assays in human heart tissue sections and primary cardiomyocytes showed that miR-665 was localized in the nucleus of cardiomyocytes.Increased expression of nuclear miR-665 was observed not only in the cardiomyocytes isolated from the heart of mice treated in vivo by transverse aortic constriction(TAC),but also in phenylephrine(PE)-treated cultured cardiomyocytes in vitro.To further explore the role of miR-665 in heart failure,a type 9 recombinant adeno-associated virus(rAAV)system was employed to manipulate the expression of miR-665 in mice.Overexpression of miR-665 aggravated TAC-induced cardiac dysfunction,while down-expression of miR-665 showed opposite effects.Bioinformatic prediction and biological validation confirmed that the PTEN(phosphatase and tensin homolog)gene was one of the targets of miR-665 in the nucleus.Furthermore,restoring PTEN expression significantly eliminated the destructive effects of miR-665 over-expression in TAC-induced cardiac dysfunction.Our data showed that nuclear miR-665 aggravates heart failure via inhibiting PTEN expression,which provided a therapeutic approach for heart failure. | Jiahui Fan Xudong Zhang Xiang Nie Huaping Li Shuai Yuan Beibei Dai Jiabing Zhan Zheng Wen Jiangang Jiang Chen Chen Daowen Wang | 2020 | Science China(Life Sciences)2020，63，5： | 4 |

| 4 | Precisely quantifying bulk transition metal valence evolution in conventional battery electrode by inverse partial fluorescence yield显示文摘Precisely quantifying transition metal(TM) redox in bulk is a key to understand the fundamental of optimizing cathode materials in secondary batteries. At present, the commonly used methods to probe TM redox are hard X-ray absorption spectroscopy(hXAS) and soft X-ray absorption spectroscopy(sXAS).However, they are both facing challenges to precisely quantify the valence states of some transition metals such as Mn. In this paper, Mn-L iPFY(inverse partial fluorescence yield) spectra extracted from Mn-L m RIXS(mapping of resonant inelastic X-ray scattering) is adopted to quantify Mn valence states. Mn-L i PFY spectra has been considered as a bulk-sensitive, non-distorted probe of TM valence states.However, the exact precision of this method is still unclear in quantifying practical battery electrodes.Herein, a series of LiMn_(2)O_(4) electrodes with different charge and discharge states are prepared. Based on their electrochemical capacity(generally considered to be very precise), the precision of Mn iPFY in quantifying bulk Mn valence state is confirmed, and the error range is unraveled. Mn-L mRIXS iPFY thus is identified as one of the best methods to quantify the bulk Mn valence state comparing with hXAS and sXAS. | Kehua Dai Weiwei Shao Beibei Zhao Wenjuan Zhang Yan Feng Wenfeng Mao Guo Ai Gao Liu Jing Mao Wanli Yang | 2022 | Journal of Energy Chemistry2022，31，6： | 1 |

| 7 | Phonon-assisted upconversion in twisted two-dimensional semiconductors显示文摘Phonon-assisted photon upconversion(UPC)is an anti-Stokes process in which incident photons achieve higher energy emission by absorbing phonons.This letter studies phonon-assisted UPC in twisted 2D semiconductors,in which an inverted contrast between UPC and conventional photoluminescence(PL)of WSe2 twisted bilayer is emergent.A 4-fold UPC enhancement is achieved in 5.5°twisted bilayer while PL weakens by half.Reduced interlayer exciton conversion efficiency driven by lattice relaxation,along with enhanced pump efficiency resulting from spectral redshift,lead to the rotation-angle-dependent UPC enhancement.The counterintuitive phenomenon provides a novel insight into a unique way that twisted angle affects UPC and light-matter interactions in 2D semiconductors.Furthermore,the UPC enhancement platform with various superimposable means offers an effective method for lighting bilayers and expanding the application prospect of 2D stacked van der Waals devices. | Yuchen Dai Pengfei Qi Guangyi Tao Guangjie Yao Beibei Shi Zhixin Liul Zhengchang Liu Xiao He Pu Peng Zhibo Dang Liheng Zheng Tianhao Zhang Yongji Gong Yan Guan Kaihui Liu Zheyu Fang | 2023 | Light(Science & Applications)2023，12，1： | 0 |
| 8 | Hydrophobic 1-octadecanethiol functionalized copper catalyst promotes robust high-current CO_(2) gas-diffusion electrolysis显示文摘The electrocatalytic reduction of CO_(2) presents a promising strategy in addressing environmental and energy crisis.Significant progress has been achieved via CO_(2) gas diffusion electrolysis,to react at high selectivity and high rate.However,the gas diffusion layer(GDL)of the gas diffusion electrode(GDE)still suffers from low tolerance and limited active sites.Here,the hydrophobic 1-octadecanethiol molecular was functionalized over the Cu catalyst layer of the GDE,which simultaneously stabilizes the GDL and exposes abundant active solid-liquid-gas three-phase interfaces.The resultant GDE exhibits multi-carbon(C_(2+))product selectivity over faradaic efficiency(FE)of 70.0%in the range of 100 to 800 mA·cm^(-2),with the peak FE^(c2+)of 85.2%at 800 mA·cm^(-2).Notably,the strengthened GDE could continuously drive high-current electrolysis for more than 100 h without flooding.This work opens a new way to improve CO_(2) gas diffusion electrolysis via surface molecular engineering. | Liangyao Xue Xuefeng Wu Yuanwei Liu Beibei Xu Xuelu Wang Sheng Dai Pengfei Liu Huagui Yang | 2022 | Nano Research2022，15，2： | 0 |
