| 1 | A human circulating immune cell landscape in aging and COVID-19显示文摘Age-associated changes in immune cells have been linked to an increased risk for infection.However,a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking.Here,we combined scRNA-seq,mass cytometry and sCATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19.We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector,cytotoxic,exhausted and reg-ulatory cells,along with increased late natural killer cells,age-associated B cells,inflammatory monocytes and age-associated dendritic cells.In addition,the expression of genes,which were implicated in coron-avirus susceptibility,was upregulated in a cell subtype-specific manner with age.Notably,COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senes-cence.Therefore,these findings suggest that a dysreg-ulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly. | Yingfeng Zheng Xiuxing Liu Wenqing Le Lihui Xie He Li Wen Wen Si Wang Shuai Ma Zhaohao Huang Jinguo Ye Wen Shi Yanxia Ye Zunpeng Liu Moshi Song Weiqi Zhang Jing-Dong J.Han Juan Carlos lzpisua Belmonte Chuanle Xiao Jing Qu Hongyang Wang Guang-Hui Liu Wenru Su | 2020 | Protein & Cell2020，11，10： | 10 |

| 4 | Nanocellulose-Assisted Construction of Multifunctional MXene-Based Aerogels with Engineering Biomimetic Texture for Pressure Sensor and Compressible Electrode显示文摘Multifunctional architecture with intriguing structural design is highly desired for realizing the promising performances in wearable sensors and flexible energy storage devices.Cellulose nanofiber(CNF)is employed for assisting in building conductive,hyperelastic,and ultralight Ti_(3)C_(2)T_(x)MXene hybrid aerogels with oriented tracheid-like texture.The biomimetic hybrid aerogels are constructed by a facile bidirectional freezing strategy with CNF,carbon nanotube(CNT),and MXene based on synergistic electrostatic interaction and hydrogen bonding.Entangled CNF and CNT“mortars”bonded with MXene“bricks”of the tracheid structure produce good interfacial binding,and superior mechanical strength(up to 80%compressibility and extraordinary fatigue resistance of 1000 cycles at 50%strain).Benefiting from the biomimetic texture,CNF/CNT/MXene aerogel shows ultralow density of 7.48 mg cm^(-3)and excellent electrical conductivity(~2400 S m^(-1)).Used as pressure sensors,such aerogels exhibit appealing sensitivity performance with the linear sensitivity up to 817.3 kPa^(-1),which affords their application in monitoring body surface information and detecting human motion.Furthermore,the aerogels can also act as electrode materials of compressive solid-state supercapacitors that reveal satisfactory electrochemical performance(849.2 mF cm^(-2)at 0.8 mA cm^(-2))and superior long cycle compression performance(88%after 10,000 cycles at a compressive strain of 30%). | Ting Xu Qun Song Kun Liu Huayu Liu Junjie Pan Wei Liu Lin Dai Meng Zhang Yaxuan Wang Chuanling Si Haishun Du Kai Zhang | 2023 | Nano-Micro Letters2023，15，7： | 2 |

| 7 | Dual-functional marigold-like Zn_(x)Cd_(1-x)S homojunction for selective glucose photoreforming with remarkable H_(2)coproduction显示文摘The global commitment to pivoting to sustainable energy and products calls for technology development to utilize solar energy for hydrogen(H_(2))and value-added chemicals production by biomass photoreforming.Herein,a novel dual-functional marigold-like Zn_(x)Cd_(1-x)S homojunction has been the production of lactic acid with high-yield and H_(2)with high-efficiency by selective glucose photoreforming.The optimized Zn_(0.3)Cd_(0.7)S exhibits outstanding H_(2)generation(13.64 mmol h^(-1)g^(-1)),glucose conversion(96.40%),and lactic acid yield(76.80%),over 272.80 and 19.21 times higher than that of bare ZnS(0.05 mmol h^(-1)g^(-1))and CdS(0.71 mmol h^(-1)g^(-1))in H_(2)generation,respectively.The marigold-like morphology provides abundant active sites and sufficient substrates accessibility for the photocatalyst,while the specific role of the homojunction formed by hexagonal wurtzite(WZ)and cubic zinc blende(ZB)in photoreforming biomass has been demonstrated by density functional theory(DFT)calculations.Glucose is converted to lactic acid on the WZ surface of Zn_(0.3)Cd_(0.7)S via the photoactive species·O_(2)^(-),while the H_(2)is evolved from protons(H^(+))in H_(2)O on the ZB surface of Zn_(0.3)Cd_(0.7)S.This work paves a promising road for the production of sustainable energy and products by integrating photocatalysis and biorefine. | Fuyan Kang Cai Shi Yeling Zhu Malin Eqi Junming Shi Min Teng Zhanhua Huang Chuanling Si Feng Jiang Jinguang Hu | 2023 | Journal of Energy Chemistry2023，，4： | 1 |

| 10 | Sustainable preparation and characterization of thermally stable and functional cellulose nanocrystals and nanofibrils via formic acid hydrolysis显示文摘In this work,a sustainable method to prepare functional cellulose nanocrystals(CNCs)and cellulose nanofibrils(CNFs)using formic acid(FA)(a recoverable organic acid)was established.After FA hydrolysis,the obtained CNCs could be well dispersed in DMAC.Thus,the CNC products and fibrous cellulosic solid residue(FCSR)in DMAC could be easily separated by a conventional centrifugal process,and the collected FCSR could be further fibrillated to CNFs with relatively low-intensity mechanical fibrillation process.The isolated CNC products showed high crystallinity index(about 75%)and excellent thermal stability(with onset thermal degradation temperature of 325℃).Both the resultant CNCs and CNFs showed better dispersibility in DMSO,DMF and DMAC respectively because of the introduction of ester groups on the surface of the products.The presence of surface ester groups could increase the interface compatibility of nanocelluloses with polymeric matrices and enable their applications in reinforcing polymeric matrix materials(e.g.the composite films like PHVB+CNFs). | Haishun Du Chao Liu Dong Wang Yuedong Zhang Guang Yu Chuanling Si Bin Li Xindong Mu Hui Peng | 2017 | Journal of Bioresources and Bioproducts2017，2，1： | 1 |
| 11 | Evaluation and Improvement of Antioxidant Activity of Water-soluble Lignin Products from Steam Explosion Processing of Corn Stalk显示文摘In this study,corn stalk was pretreated by steam explosion under various processing conditions,and the antioxidant activity of hydrolysates in the post-process washing liquor was analyzed using the 1,1'-diphenyl-2-picrylhydrazyl(DPPH•)scavenging method.The yield and composition of the hydrolysates obtained under different treatment conditions were also determined;the results indicated that the steam explosion extent had a significant effect on both properties.Under optimized conditions(1.5 MPa,20 min),the obtained hydrolysate had the highest phenolic compound yield(18.6 mg/g untreated corn stalk)and the highest radical scavenging capacity(IC_(50)=0.24 mg/mL).To confirm the positive effect of phenolic compounds on the antioxidant activity of the hydrolysate,one-step ethanol fractionation was carried out.Due to the enrichment of phenolic compounds,the ethanolsoluble fraction(ESF)exhibited significantly enhanced antioxidant activity with an IC_(50) value of 0.06 mg/mL,which was close to that of butylated hydroxytoluene(BHT,IC_(50)=0.056 mg/mL).Consequently,this work indicated that phenolic compounds have a significant effect on the antioxidant activity of hydrolysate from steam-exploded corn stalk and that simple one-step ethanol fractionation is an effective way to enrich the phenolic compounds in the hydrolysate and improve the antioxidant activity. | Hao Sun Rui Wang Guanhua Wang Wenjie Sui Chuanling Si | 2021 | Paper And Biomaterials2021，6，3： | 1 |
