| 1 | Nonradical-dominated peroxymonosulfate activation through bimetallic Fe/Mn-loaded hydroxyl-rich biochar for efficient degradation of tetracycline显示文摘Biochar-based transition metal catalysts have been identified as excellent peroxymonosulfate(PMS)activators for producing radicals used to degrade organic pollutants.However,the radical-dominated pathways for PMS activation severely limit their practical applications in the degradation of organic pollutants from wastewater due to side reactions between radicals and the coexisting anions.Herein,bimetallic Fe/Mn-loaded hydroxyl-rich biochar(FeMn-OH-BC)is synthesized to activate PMS through nonradical-dominated pathways.The as-prepared FeMn-OH-BC exhibits excellent catalytic activity for degrading tetracycline at broad pH conditions ranging from 5 to 9,and about 85.0%of tetracycline is removed in 40 min.Experiments on studying the influences of various anions(HCO_(3)^(−),NO_(3)^(−),and H_(2)PO_(4)^(−))show that the inhibiting effect is negligible,suggesting that the FeMn-OHBC based PMS activation is dominated by nonradical pathways.Electron paramagnetic resonance measurements and quenching tests provide direct evidence to confirm that 1O2 is the major reactive oxygen species generated from FeMn-OH-BC based PMS activation.Theoretical calculations further reveal that the FeMn-OH sites in FeMn-OH-BC are dominant active sites for PMS activation,which have higher adsorption energy and stronger oxidative activity towards PMS than OH-BC sites.This work provides a new route for driving PMS activation by biochar-based transition metal catalysts through nonradical pathways. | Yihui Li Deying Lin Yongfu Li Peikun Jiang Xiaobo Fang Bing Yu | 2023 | Nano Research2023，16，1： | 3 |
| 2 | Retinoic acid can improve autophagy through depression of the PI3K-Akt-mTOR signaling pathway via RARαto restore spermatogenesis in cryptorchid infertile rats显示文摘Cryptorchidism-caused adult infertility is a common component of idiopathic reasons for male infertility.Retinoic acid(RA)has a vital effect on the spermatogenesis process.Here,we found that the expression of c-Kit,Stra8,and Sycp3 could be up-regulated via the activation of retinoic acid receptorα(RARα)after RA supplementation in neonatal cryptorchid infertile rats.We also demonstrated that the protein expression of PI3K,p-Akt/pan-Akt,and p-mTOR/mTOR was higher in cryptorchid than in normal testes,and could be suppressed with RA in vivo.After RA treatment in infertile cryptorchid testis in vivo,the levels of the autophagy proteins LC3 and Beclin1 increased and those of P62 decreased.Biotin tracer indicated that the permeability of blood-testis barrier(BTB)in cryptorchid rats decreased after RA administration.Additionally,after blocking the RARαwith AR7(an RARαantagonist)in testicle culture in vitro,we observed that compared with normal testes,the PI3K-Akt-mTOR signaling pathway and the autophagy pathway was increased and decreased,respectively,which were coincident with cryptorchisd testes in vivo.Additionally,the appropriate concentrations of RA treatment could depress the PI3K-Akt-mTOR signaling pathway and improve the autophagy pathway.The results confirmed that RA can rehabilitate BTB function and drive key protein levels in spermatogonial differentiation through depressing the PI3K-Akt-mTOR signaling pathway via RARα. | Chunlan Long Yu Zhou Lianju Shen Yihang Yu Dong Hu Xing Liu Tao Lin Dawei He Tao Xu Deying Zhang Jing Zhu Guanghui Wei | 2022 | Genes & Diseases2022，9，5： | 2 |

| 4 | Structural evolution of layered oxide cathodes for spent Li-ion batteries:Degradation mechanism and repair strategy显示文摘Sustainable development has long been recognized as one of the most critical issues in today’s energy and environment-conscious society.It has never been more urgent to recycle and reuse the end-of-life cathode materials.Here,this work systematically investigates the structure-critical degradation mechanism of polycrystalline LiNi_(x)Co_(y)Mn_(1−x−y)O_(2)(NCM),combining experimental characterization and DFT simulations.Targeting the key degradation factors,a synergistic repair strategy based on deep mechanochemical activation and heat treatment was successfully proposed to direct regenerate the degradedNCMmaterial.Studies indicate the induction and promotion of synergistic repair technique on the reconstruction of particlemorphology,the recovery of the chemical composition and crystal structure,and the favorable transformation of the impurities phase in the failed materials.In particular,the synergistic repair process induces a gradient distribution of LiF and further enables partial fluorine doping into the NCM surface,forming abundant oxygen vacancies and increasing the content of highly reactive Ni2+.Benefiting from the comprehensive treatment for the multi-scale and multi-form degradation behaviors,the repaired material exhibits a capacity of 176.8 mA h g^(-1)at 0.1 C,which is comparable to the corresponding commercial material(172.8 mA h g^(-1)).The satisfactory capacity of the recovered cathode proves that it is an effective direct renovating strategy. | Shan Jin Jianquan Liang Deying Mu Tianning Lin Yuyang Tian Jian Zhang YueWang Meng Chen Qingmo Shi Changsong Dai | 2023 | SusMat2023，3，3： | 1 |

| 6 | Bioinformatic identification of key genes and molecular pathways in the spermatogenic process of cryptorchidism显示文摘This study aims to determine key genes and pathways that could play important roles in the spermatogenic process of patients with cryptorchidism.The gene expression profile data of GSE25518 was obtained from the Gene Expression Omnibus(GEO)database.Microarray data were analyzed using BRB-Array Tools to identify differentially expressed genes(DEGs)between high azoospermia risk(HAZR)patients and controls.In addition,other analytical methods were deployed,including hierarchical clustering analysis,class comparison between patients with HAZR and the normal control group,gene ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis,and the construction of a proteineprotein interaction(PPI)network.In total,1015 upregulated genes and 1650 downregulated genes were identified.GO and KEGG analysis revealed enrichment in terms of changes in the endoplasmic reticulum cellular component and the endoplasmic reticulum protein synthetic process in the HAZR group.Furthermore,the arachidonic acid pathway and mTOR pathway were also identified as important pathways,while RICTOR and GPX8 were indentified as key genes involved in the spermatogenic process of patients with cryptorchidism.In present study,we found that changes in the synthesis of endoplasmic reticulum proteins,arachidonic acid and the mTOR pathway are important in the incidence and spermatogenic process of cryptorchidism.GPX8 and RICTOR were also identified as key genes associated with cryptorchidism.Collectively,these data may provide novel clues with which to explore the precise etiology and mechanism underlying cryptorchidism and cryptorchidism-induced human infertility. | Yu Zhou Deying Zhang Bo Liu Dong Hu Lianju Shen Chunlan Long Yihang Yu Tao Lin Xing Liu Dawei He Guanghui Wei | 2019 | Genes & Diseases2019，6，4： | 1 |
| 7 | Influence of Four Factors on Discharge Capacity and Self-Discharge Rate of Iron Electrode显示文摘Ni-Fe rechargeable batteries possess the advantages of long cycle life, high theoretical specific energy, abundant raw material,Iow price and environmental friendship. It has a wide applied perspective. The advantages, disadvantages and preparation methods of iron electrodes were summarized. The influence of four factors on discharge capacity and self-discharge rate of iron electrode were discussed by means of orthogonal experiments, galvanostatic charges and discharges. The influences of graphite on the discharge capacity and self-discharge rate of iron electrode were the most remarkable, the most unapparent influences on the discharge capacity and self-discharge rate were HPMC (hydroxy propoxy methoxy cellulose) and sodium sulphide, respectively. The aim of the present research was to study the effects of graphite, HPMC and iron powder added in the electrodes, sodium sulphide added in the electrolytes on the discharge capacity and self-discharge rate of iron electrodes.The largest discharge capacity of the iron electrodes was 488.5 mAh/g-Fe at 66.4 mA/g-Fe in the first ten cycles, and the average self-discharge rate was 0.367% per hour. | Dongfeng LIN, Shihai YE, Rong CAI, Deying SONG and Panwen SHENInstitute of New Energy Material Chemistry, Nankai University, Tianjin 300071, China | 2003 | Journal of Materials Science & Technology2003，19，6： | 0 |
