| 1 | Light-driven soft actuator based on graphene and WSe2 nanosheets composite for multimodal motion and remote manipulation显示文摘Remote controlled soft actuators have attracted ever-increasing interest in industrial,medical,robotics,and engineering fields.Soft actuators are charming than normal tools in executing dedicate tasks due to small volume and flexible body they have.However,it remains a challenge to design soft actuator that can adapt to multi-environments under remote stimuli with promising nano materials.Herein,we have developed a kind of near-infrared laser driven soft actuators with multi locomotive modes based on WSe2 and graphene nanosheets heterojunction.Different locomotion modes are driven by photothermal effect induced deformation to adapt to different working conditions.Moreover,the specially designed gripper driven by pulsed laser can lift a heavy load which is four times of its weight.This work broadens the choice of advanced nanomaterials for photothermal conversion of soft actuators.It is promising to realize applications including photothermal therapy and complex environment detection through the combination of the intelligent robot design and optical fiber system. | Zewen Su Yingjie Zhao Youqiang Huang Chaoyue Xu Xiaolei Yang Binrui Wang Beibei Xu Shiqing Xu Gongxun Bai | 2023 | Nano Research2023，16，1： | 0 |
| 2 | 40 Hz light flickering promotes sleep through cortical adenosine signaling显示文摘Flickering light stimulation has emerged as a promising non-invasive neuromodulation strategy to alleviate neuropsychiatric disorders.However,the lack of a neurochemical underpinning has hampered its therapeutic development.Here,we demonstrate that light flickering triggered an immediate and sustained increase(up to 3 h after flickering)in extracellular adenosine levels in the primary visual cortex(V1)and other brain regions,as a function of light frequency and intensity,with maximal effects observed at 40 Hz frequency and 4000 lux.We uncovered cortical(glutamatergic and GABAergic)neurons,rather than astrocytes,as the cellular source,the intracellular adenosine generation from AMPK-associated energy metabolism pathways(but not SAM-transmethylation or salvage purine pathways),and adenosine efflux mediated by equilibrative nucleoside transporter-2(ENT2)as the molecular pathway responsible for extracellular adenosine generation.Importantly,40 Hz(but not 20 and 80 Hz)light flickering for 30 min enhanced non-rapid eye movement(non-REM)and REM sleep for 2–3 h in mice.This somnogenic effect was abolished by ablation of V1(but not superior colliculus)neurons and by genetic deletion of the gene encoding ENT2(but not ENT1),but recaptured by chemogenetic inhibition of V1 neurons and by focal infusion of adenosine into V1 in a dose-dependent manner.Lastly,40 Hz light flickering for 30 min also promoted sleep in children with insomnia by decreasing sleep onset latency,increasing total sleep time,and reducing waking after sleep onset.Collectively,our findings establish the ENT2-mediated adenosine signaling in V1 as the neurochemical basis for 40 Hz flickering-induced sleep and unravel a novel and non-invasive treatment for insomnia,a condition that affects 20%of the world population. | Xuzhao Zhou Yan He Tao Xu Zhaofa Wu Wei Guo Xi Xu Yuntao Liu Yi Zhang Huiping Shang Libin Huang Zhimo Yao Zewen Li Lingya Su Zhihui Li Tao Feng Shaomin Zhang Olivia Monteiro Rodrigo A.Cunha Zhi-Li Huang Kang Zhang Yulong Li Xiahong Cai Jia Qu Jiang-Fan Chen | 2024 | Cell Research2024，34，3： | 0 |
| 3 | Increased long-distance and homo-trans interactions related to H3K27me3 in Arabidopsis hybrids显示文摘In plants,the genome structure of hybrids changes compared with their parents,but the effects of these changes in hybrids remain elusive.Comparing reciprocal crosses between Col×C24 and C24×Col in Arabidopsis using high-throughput chromosome conformation capture assay(Hi-C)analysis,we found that hybrid three-dimensional(3D)chromatin organization had more long-distance interactions relative to parents,and this was mainly located in promoter regions and enriched in genes with heterosis-related pathways.The interactions between euchromatin and heterochromatin were increased,and the compartment strength decreased in hybrids.In compartment domain(CD)boundaries,the distal interactions were more in hybrids than their parents.In the hybrids of CURLY LEAF(clf)mutants clfCol×clfC24and clfC24×clfCol,the heterosis phenotype was damaged,and the long-distance interactions in hybrids were fewer than in their parents with lower H3K27me3.ChIP-seq data revealed higher levels of H3K27me3 in the region adjacent to the CD boundary and the same interactional homo-trans sites in the wild-type(WT)hybrids,which may have led to more long-distance interactions.In addition,the differentially expressed genes(DEGs)located in the boundaries of CDs and loop regions changed obviously in WT,and the functional enrichment for DEGs was different between WT and clf in the longdistance interactions and loop regions.Our findings may therefore propose a new epigenetic explanation of heterosis in the Arabidopsis hybrids and provide new insights into crop breeding and yield increase. | Zhaoxu Gao Yanning Su Le Chang Guanzhong Jiao Yang Ou Mei Yang Chao Xu Pengtao Liu Zejia Wang Zewen Qi Wenwen Liu Linhua Sun Guangming He Xing Wang Deng Hang He | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |
| 4 | Comparative Study of the Effects of Nano ZnO and CuO on the Biodegradation,Biocompatibility,and Antibacterial Properties of Micro-arc Oxidation Coating of Magnesium Alloy显示文摘This research systematically examined the degradation,antibacterial effects,and biocompatibility of micro-arc oxidation(MAO)coatings with nano CuO and ZnO on extruded Mg alloys.Both copper(Cu)and Zinc(Zn)possess antibacterial properties.The findings demonstrated that adding ZnO will appreciably reduce the degradation rate of MAO-coating alloy due to the self-sealing micro holes.CuO+MAO coating exhibited excellent antibacterial performance,with an antibacterial rate of over 90%within 6 h co-cultured with Staphylococcus aureus.Similarly,the antibacterial rate of ZnO+MAO coating reached 90%after 12 h co-culture.Cytotoxicity test using MG63 cell indicated that the incorporation of CuO and ZnO did not notably affect the cell viability rate of the coating.Moreover,after 14 days of culture,the CuO+MAO and ZnO+MAO coated samples exhibited higher alkaline phosphatase(ALP)activity than the MAO-coated and uncoated samples,suggesting favorable osteogenic properties. | Ying Shen Xianfeng Shan Iniobong P.Etim Muhammad Ali Siddiqui Yang Yang Zewen Shi Xuping Su Junxiu Chen | 2024 | Acta Metallurgica Sinica(English Letters)2024，37，2： | 0 |
| 5 | Textured Asymmetric Membrane Electrode Assemblies of Piezoelectric Phosphorene and Ti_(3)C_(2)T_(x)MXene Heterostructures for Enhanced Electrochemical Stability and Kinetics in LIBs显示文摘Black phosphorus with a superior theoretical capacity(2596 mAh g^(-1))and high conductivity is regarded as one of the powerful candidates for lithium-ion battery(LIB)anode materials,whereas the severe volume expansion and sluggish kinetics still impede its applications in LIBs.By contrast,the exfoliated two-dimensional phosphorene owns negligible volume variation,and its intrinsic piezoelectricity is considered to be beneficial to the Li-ion transfer kinetics,while its positive influence has not been discussed yet.Herein,a phosphorene/MXene heterostructure-textured nanopiezocomposite is proposed with even phosphorene distribution and enhanced piezo-electrochemical coupling as an applicable free-standing asymmetric membrane electrode beyond the skin effect for enhanced Li-ion storage.The experimental and simulation analysis reveals that the embedded phosphorene nanosheets not only provide abundant active sites for Li-ions,but also endow the nanocomposite with favorable piezoelectricity,thus promoting the Li-ion transfer kinetics by generating the piezoelectric field serving as an extra accelerator.By waltzing with the MXene framework,the optimized electrode exhibits enhanced kinetics and stability,achieving stable cycling performances for 1,000 cycles at 2 A g^(-1),and delivering a high reversible capacity of 524 m Ah g^(-1)at-20℃,indicating the positive influence of the structural merits of self-assembled nanopiezocomposites on promoting stability and kinetics. | Yihui Li Juan Xie Ruofei Wang Shugang Min Zewen Xu Yangjian Ding Pengcheng Su Xingmin Zhang Liyu Wei Jing‑Feng Li Zhaoqiang Chu Jingyu Sun Cheng Huang | 2024 | Nano-Micro Letters2024，16，4： | 0 |
