| 1 | A family of high-temperature ferromagnetic monolayers with locked spin-dichroism-mobility anisotropy: MnNX and CrCX(X=Cl,Br,I;C=S,Se,Te)显示文摘Two-dimensional magnets have received increasing attention since Cr_2Ge_2Te_6 and CrI_3 were experimentally exfoliated and measured in 2017. Although layered ferromagnetic metals were demonstrated at room temperature, a layered ferromagnetic semiconductor with high Curie temperature(Tc) is yet to be unveiled. Here, we theoretically predicted a family of high Tcferromagnetic monolayers, namely MnNX and CrCX(X = Cl, Br and I; C = S, Se and Te). Their Tcvalues were predicted from over 100 K to near 500 K with Monte Carlo simulations using an anisotropic Heisenberg model. Eight members among them show semiconducting bandgaps varying from roughly 0.23 to 1.85 eV. These semiconducting monolayers also show extremely large anisotropy, i.e. ~10~1 for effective masses and ~10~2 for carrier mobilities, along the two in-plane lattice directions of these layers. Additional orbital anisotropy leads to a spin-locked linear dichroism, in different from previously known circular and linear dichroisms in layered materials.Together with the mobility anisotropy, it offers a spin-, dichroism-and mobility-anisotropy locking.These results manifest the potential of this 2D family for both fundamental research and high performance spin-dependent electronic and optoelectronic devices. | Cong Wang Xieyu Zhou Linwei Zhou Ning-Hua Tong Zhong-Yi Lu Wei Ji | 2019 | Science Bulletin2019，64，5： | 5 |
| 2 | Strategies of Removing Residual Lithium Compounds on the Surface of Ni-Rich Cathode Materials显示文摘Ni-rich cathode materials have become one of the most promising cathode materials for advanced high-energy Li-ion batteries(LIBs)owing to their high specific capacity.However,Ni-rich cathode materials are sensitive to the trace H2O and CO2 in the air,and tend to react with them to generate LiOH and Li2COg at the particle surface region(named residual lithium compounds,labeled as RLCs).The RLCs will deteriorate the comprehensive performances of Ni-rich cathode materials and make trouble in the subsequent manufacturing process of electrode,including causing low initial coulombic efficiency and poor storage property,bringing about potential safety hazards,and gelatinizing the electrode slurry.Therefore,it is of considerable significance to remove the RLCs.Researchers have done a lot of work on the corresponding field,such as exploring the formation mechanism and elimination methods.This paper investigates the origin of the surface residual lithium compounds on Ni-rich cathode materials,analyzes their adverse effects on the per-formance and the subsequent electrode production process,and summarizes various kinds of feasible methods for removing the RLCS.Finally,we propose a new research direction of eliminating the lithium residuals after comparing and summing up the above.We hope this work can provide a reference for alleviating the adverse effects of residual lithium compounds for Ni-rich cathode materials'industrial production. | Yuefeng Su Linwei Li Gang Chen Lai Chen Ning Li Yun Lu Liying Bao Shi Chen Feng Wu | 2021 | Chinese Journal of Chemistry2021，39，1： | 4 |
| 3 | Engineered platelets-based drug delivery platform for targeted thrombolysis显示文摘Thrombolytic agents have thus far yielded limited therapeutic benefits in the treatment of thrombotic disease due to their short half-life,low targeting ability,and association with serious adverse reactions,such as bleeding complications.Inspired by the natural roles of platelets during thrombus formation,we fabricated a platelet-based delivery system(NO@uPA/PLTs)comprising urokinase(uPA)and arginine(Arg)for targeted thrombolysis and inhibition of re-embolism.The anchoring of uPA to the platelet surface by lipid insertion increased the thrombotic targeting and in vivo circulation duration of uPA without disturbing platelet functions.Nitric oxide(NO)generated by the loaded Arg inhibited platelet aggregation and activation at the damaged blood vessel,thereby inhibiting re-embolism.NO@uPA/PLTs effectively accumulated at the thrombi in pulmonary embolism and carotid artery thrombosis model mice and exerted superior thrombolytic efficacy.In addition,the platelet delivery system showed excellent thrombus recurrence prevention ability in a mouse model of secondary carotid artery injury.The coagulation indicators in vivo showed that the platelet-based uPA and NO co-delivery system possessed a low hemorrhagic risk,providing a promising tool for rapid thrombolysis and efficient inhibition of posttreatment re-embolism. | Songli Wang Ruifeng Wang Nana Meng Linwei Lu Jun Wang Jianfen Zhou Jiasheng Lu Qianzhu Xu Cao Xie Changyou Zhan Yao Li Yang Yu Weiyue Lu Min Liu | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 1 |
| 4 | Kidney-Qi deficiency diagnosed by Deng's diagnosis standard was not correlated with aging based on clinical observation of 90 participants显示文摘OBJECTIVE: To verify the Traditional Chinese Medicine(TCM) theory that kidney-Qi deficiency(KQD)is considered to be the main cause of aging using cross-sectional study.METHODS: Demographic and lifestyle characteristics of 90 healthy participants were collected with a self-administered questionnaire. KQD syndrome was diagnosed according to Deng's diagnosis standard. Creatinine-adjusted urinary 8-hydroxy-2'-deoxyguanosine(8-OH-dG) and 8-isomeric-prostaglandin2α(8-iso-PGF2α), salivary advanced oxidation protein products(AOPPs), malondialdehyde(MDA) and dehydroepiandrosterone-sulfate(DHEA-S) were selected as aging markers and measured using enzyme-linked immunosorbent assay.RESULTS: No significant differences were observed in participant characteristics between the KQD group and non-KQD(NKQD) group(P > 0.05). Levels of 8-OH-dG, 8-iso-PGF2α, AOPPs, and MDA increased with age, except for a slight decrease in8-OH-dG in the older group. The increase in8-iso-PGF2α was significant(P < 0.05). DHEA-S significantly decreased with increasing age(P < 0.01).8-OH-dG levels were higher in the KQD group compared with the NKQD group. Levels of urinary8-iso-PGF2α, salivary AOPPs, and MDA in the KQD group were lower than in the NKQD group. Salivary DHEA-S was higher in the KQD group compared with the NKQD group. However, differences between KQD group and NKQD group were not significant.CONCLUSION: The current results suggested that KQD syndrome, as diagnosed by Deng's standard,does not underlie the aging phenotype. | Zhao Zhengxiao Liu Lumei Tang Zihui Mohammadtursun Nabijan Lu Linwei Li Mihui Lü Yibao Mo Shuming Ma Wenjuan Wang Meng Wei Ying Gong Weiyi Dong Jingcheng | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 0 |
| 5 | Travel-related Importation and Exportation Risks of SARS-CoV-2 Omicron Variant in 367 Prefectures(Cities)-China,2022显示文摘Introduction:Minimizing the importation and exportation risks of coronavirus disease 2019(COVID-19)is a primary concern for sustaining the“Dynamic COVID-zero”strategy in China.Risk estimation is essential for cities to conduct before relaxing border control measures.Methods:Informed by the daily number of passengers traveling between 367 prefectures(cities)in China,this study used a stochastic metapopulation model parameterized with COVID-19 epidemic characteristics to estimate the importation and exportation risks.Results:Under the transmission scenario(R0=5.49),this study estimated the cumulative case incidence of Changchun City,Jilin Province as 3,233(95%confidence interval:1,480,4,986)before a lockdown on March 14,2022,which is close to the 3,168 cases reported in real life by March 16,2022.In a total of 367 prefectures(cities),127(35%)had high exportation risks according to the simulation and could transmit the disease to 50%of all other regions within a period from 17 to 94 days.The average time until a new infection arrives in a location in 1 of the 367 prefectures(cities)ranged from 26 to 101 days.Conclusions:Estimating COVID-19 importation and exportation risks is necessary for preparedness,prevention,and control measures of COVID-19—especially when new variants emerge. | Yuan Bai Mingda Xu Caifen Liu Mingwang Shen Lin Wang Linwei Tian Suoyi Tan Lei Zhang Petter Holme Xin Lu Eric H.Y.Lau Benjamin J.Cowling Zhanwei Du | 2022 | China CDC weekly2022，4，40： | 0 |
| 6 | Band alignment and interlayer hybridization in monolayer organic/WSe_(2) heterojunction显示文摘Semiconducting heterojunctions(HJs),comprised of atomically thin transition metal dichalcogenides(TMDs),have shown great potentials in electronic and optoelectronic applications.Organic/TMD hybrid bilayers hold enhanced pumping efficiency of interfacial excitons,tunable electronic structures and optical properties,and other superior advantages to these inorganic HJs.Here,we report a direct probe of the interfacial electronic structures of a crystalline monolayer(ML)perylene-3,4,9,10-tetracarboxylic-dianhydride(PTCDA)/ML-WSe_(2) HJ using scanning tunneling microscopy,photoluminescence,and first-principle calculations.Strong PTCDAAA/Se_(2) interfacial interactions lead to appreciable hybridization of the WSe_(2) conduction band with PTCDA unoccupied states,accompanying with a significant amount of PTCDA-to-WSe_(2) charge transfer(by 0.06 e/PTCDA).A type-ll band alignment was directly determined with a valence band offset of-1.69 eV,and an apparent conduction band offset of-1.57 eV.Moreover,we found that the local stacking geometry at the HJ interface differentiates the hybridized interfacial states. | Yanping Guo Linlu Wu Jinghao Deng Linwei Zhou Wei Jiang Shuangzan Lu Da Huo Jiamin Ji Yusong Bai Xiaoyu Lin Shunping Zhang Hongxing Xu Wei Ji Chendong Zhang | 2022 | Nano Research2022，15，2： | 0 |
| 7 | All-stage targeted therapy for the brain metastasis from triple-negative breast cancer显示文摘Brain metastasis is a common and serious complication of breast cancer,which is commonly associated with poor survival and prognosis.In particular,the treatment of brain metastasis from triplenegative breast cancer(BM-TNBC)has to face the distinct therapeutic challenges from tumor heterogeneity,circulating tumor cells(CTCs),blood-brain barrier(BBB)and blood-tumor barrier(BTB),which is in unmet clinical needs.Herein,combining with the advantages of synthetic and natural targeting moieties,we develop a“Y-shaped”peptide pVAP-decorated platelet-hybrid liposome drug delivery system to address the all-stage targeted drug delivery for the whole progression of BM-TNBC.Inherited from the activated platelet,the hybrid liposomes still retain the native affinity toward CTCs.Further,the peptide-mediated targeting to breast cancer cells and transport across BBB/BTB are demonstrated in vitro and in vivo.The resultant delivery platform significantly improves the drug accumulation both in orthotopic breast tumors and brain metastatic lesions,and eventually exhibits an outperformance in the inhibition of BM-TNBC compared with the free drug.Overall,this work provides a promising prospect for the comprehensive treatment of BMTNBC,which could be generalized to other cell types or used in imaging platforms in the future. | Zimiao Luo Sunyi Wu Jianfen Zhou Weixia Xu Qianzhu Xu Linwei Lu Cao Xie Yu Liu Weiyue Lu | 2023 | Acta Pharmaceutica Sinica B2023，13，1： | 0 |
