| 2 | Coupling of Hierarchical Al_(2)O_(3)/TiO_(2) Nanofibers into 3D Photothermal Aerogels Toward Simultaneous Water Evaporation and Purification显示文摘Serious freshwater shortage and environmental pollution boost the rapid development of solar-driven water production.Although improved evaporation rate has achieved in recent years,undesirable impurity(e.g.,pollutant components)can also be inevitably evaporated and collected as impurity in produced freshwater.This work reports new ultra-light three-dimensional(3D)aerogels assembled by hierarchical Al_(2)O_(3)/TiO_(2) nanofibers and reduced graphene oxide(RGO)for excit-ing synchronized solar-driven evaporation and water purification.Hydrophilic Al_(2)O_(3)/TiO_(2) fibrous channels linked up the graphene hot-spots and water body for sufficient water supply and bulk water insulation.Meanwhile,featured with thermal insulation effect,the Al_(2)O_(3)/TiO_(2) nanofibers effectively locked the converted heat with less energy loss from sunlight.The introducing of Al_(2)O_(3)/TiO_(2) nanofibers into RGO aerogel led to the effective interfacial evaporation for a more rapid water evaporation rate(2.19 kg·m−2·h−1,normalized to evaporation area including both top and side surface),which was 36%higher than that of pristine RGO aerogel.Moreover,simultaneous with the strong steam generation,Al_(2)O_(3)/TiO_(2) nanofibers in situ removed the pollutants within steam by photodegradation,achieving polluted wastewater purification with high con-taminant removal ratio of 91.3%.Our work on coupling Al_(2)O_(3)/TiO_(2) nanofibers into photothermal aerogel provides attractive solutions for the challenges of clean water scarcity and serious environmental pollution. | Xiangyu Meng Wanlin Xu Zhihui Li Jianhui Yang Jingwu Zhao Xixi Zou Yueming Sun Yunqian Dai | 2020 | Advanced Fiber Materials2020，2，2： | 4 |
| 3 | An invasive zone in human liver cancer identified by Stereo-seq promotes hepatocyte–tumor cell crosstalk,local immunosuppression and tumor progression显示文摘Dissecting and understanding the cancer ecosystem,especially that around the tumor margins,which have strong implications for tumor cell infiltration and invasion,are essential for exploring the mechanisms of tumor metastasis and developing effective new treatments.Using a novel tumor border scanning and digitization model enabled by nanoscale resolution-SpaTial Enhanced REsolution Omics-sequencing(Stereo-seq),we identified a 500µm-wide zone centered around the tumor border in patients with liver cancer,referred to as“the invasive zone”.We detected strong immunosuppression,metabolic reprogramming,and severely damaged hepatocytes in this zone.We also identified a subpopulation of damaged hepatocytes with increased expression of serum amyloid A1 and A2(referred to collectively as SAAs)located close to the border on the paratumor side.Overexpression of CXCL6 in adjacent malignant cells could induce activation of the JAK-STAT3 pathway in nearby hepatocytes,which subsequently caused SAAs’overexpression in these hepatocytes.Furthermore,overexpression and secretion of SAAs by hepatocytes in the invasive zone could lead to the recruitment of macrophages and M2 polarization,further promoting local immunosuppression,potentially resulting in tumor progression.Clinical association analysis in additional five independent cohorts of patients with primary and secondary liver cancer(n=423)showed that patients with overexpression of SAAs in the invasive zone had a worse prognosis.Further in vivo experiments using mouse liver tumor models in situ confirmed that the knockdown of genes encoding SAAs in hepatocytes decreased macrophage accumulation around the tumor border and delayed tumor growth.The identification and characterization of a novel invasive zone in human cancer patients not only add an important layer of understanding regarding the mechanisms of tumor invasion and metastasis,but may also pave the way for developing novel therapeutic strategies for advanced liver cancer and other solid tumors. | Liang Wu Jiayan Yan Yinqi Bai Feiyu Chen Xuanxuan Zou Jiangshan Xu Ao Huang Liangzhen Hou Yu Zhong Zehua Jing Qichao Yu Xiaorui Zhou Zhifeng Jiang Chunqing Wang Mengnan Cheng Yuan Ji Yingyong Hou Rongkui Luo Qinqin Li Liang Wu Jianwen Cheng Pengxiang Wang Dezhen Guo Waidong Huang Junjie Lei Shang Liu Yizhen Yan Yiling Chen Sha Liao Yuxiang Li Haixiang Sun Na Yao Xiangyu Zhang Shiyu Zhang Xi Chen Yang Yu Yao Li Fengming Liu Zheng Wang Shaolai Zhou Huanming Yang Shuang Yang Xun Xu Longqi Liu Qiang Gao Zhaoyou Tang Xiangdong Wang Jian Wang Jia Fan Shiping Liu Xinrong Yang Ao Chen Jian Zhou | 2023 | Cell Research2023，33，8： | 1 |
| 4 | The RhHB1/RhLOX4 module affects the dehydration tolerance of rose flowers(Rosa hybrida)by fine-tuning jasmonic acid levels显示文摘Phytohormones are key factors in plant responsiveness to abiotic and biotic stresses,and maintaining hormone homeostasis is critically important during stress responses.Cut rose(Rosa hybrida)flowers experience dehydration stress during postharvest handling,and jasmonic acid(JA)levels change as a result of this stress.However,how JA is involved in dehydration tolerance remains unclear.We investigated the functions of the JA-and dehydration-induced RhHB1 gene,which encodes a homeodomain-leucine zipper Iγ-clade transcription factor,in rose flowers.Silencing RhHB1 decreased petal dehydration tolerance and resulted in a persistent increase in JA-Ile content and reduced dehydration tolerance.An elevated JA-Ile level had a detrimental effect on rose petal dehydration tolerance.RhHB1 was shown to lower the transient induction of JA-Ile accumulation in response to dehydration.In addition to transcriptomic data,we obtained evidence that RhHB1 suppresses the expression of the lipoxygenase 4(RhLOX4)gene by directly binding to its promoter both in vivo and in vitro.We propose that increased JA-Ile levels weaken the capacity for osmotic adjustment in petal cells,resulting in reduced dehydration tolerance.In conclusion,a JA feedback loop mediated by an RhHB1/RhLOX4 regulatory module provides dehydration tolerance by fine-tuning bioactive JA levels in dehydrated flowers. | Youwei Fan Jitao Liu Jing Zou Xiangyu Zhang Liwei Jiang Kun Liu Peitao Lü Junping Gao Changqing Zhang | 2020 | Horticulture Research2020，7，1： | 1 |
| 5 | Preparation and Optical Properties of Er^3+:Na2O-Al2O3-SiO2 Transparent Glass-Ceramics显示文摘Na_2O-Al_2O_3-SiO_2 glass-ceramics doped with Er^(3+) ions were synthesized by the conventional melt quenching technique at a low melting temperature.The samples were characterized by differential scanning calorimetry(DSC),X-ray diffraction(XRD),scanning electron microscopy(SEM),UV-vis-NIR scanning spectrophotometry,and fluorescence spectrometry.The results show that the main crystalline phase of glass-ceramics is nepheline.The best heat-treatment process is at 520 ℃ for 2 h.Because the up-conversion luminescence and near infrared luminescence properties of glass doped with Eu^(3+) are studied in detail. | 韦钦磊 张洪波 ZOU Xiangyu CHEN Chen ZHAO Mengjie WEI Yanling SONG Qiong 苏春辉 | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 1 |
| 6 | Fabrication and mechanical behavior of 2D-C_(f)/Ta_(x)Hf_(1−x)C–SiC composites by a low-temperature and highly-efficient route显示文摘C_(f)/Ta_(x)Hf_(1−x)C–SiC composites are ideal thermal structural materials for service under extreme conditions of hypersonic vehicles.However,how to synthesize TaxHf1-xC powders and efficiently fabricate C_(f)/Ta_(x)Hf_(1−x)C–SiC composites still faces some challenges.Furthermore,mechanical properties and thermophysical properties of Ta_(x)Hf_(1−x)C vary with the composition,but not monotonically.In-depth analysis of mechanical behaviors of the C_(f)/Ta_(x)Hf_(1−x)C–SiC composites is extremely important for their development and applications.In this study,the Ta_(x)Hf_(1−x)C powders(x=0.2,0.5,0.8)were successfully synthesized via solid solution of TaC and HfC at a relatively low temperature of 1800℃,with a small amount of Si as an additive.Subsequently,the efficient fabrication of 2D-C_(f)/Ta_(x)Hf_(1−x)C–SiC composites was achieved by slurry impregnation and lamination(SIL)combined with precursor infiltration and pyrolysis(PIP).In addition,the mechanical behavior of the composites was investigated systematically.It is demonstrated that the composites present remarkable non-brittle fractures,including a large number of fiber pull out and interphase debonding.Also,the fracture failure involves a complex process of microcrack generation and propagation,matrix cracking,and layer fracture.Moreover,the interfacial bonding between the fibers and the matrix is enhanced as the Ta∶Hf ratio decreases from 4∶1 to 1∶4.As a result,C_(f)/Ta_(0.2)Hf_(0.8)C–SiC composites exhibit exceptional flexural strength of 437±19 MPa,improved by 46%compared with C_(f)/Ta_(0.8)Hf_(0.2)C–SiC(299±19 MPa).This study provides a new perception of design and fabrication of ultra-high-temperature ceramic(UHTC)matrix composites with high performance. | Xuegang Zou Dewei Ni Bowen Chen Feiyan Cai Le Gao Ping He Yusheng Ding Xiangyu Zhang Shaoming Dong | 2023 | Journal of Advanced Ceramics2023，12，10： | 0 |
| 7 | Utilization of 3D printing technology in hepatopancreatobiliary surgery显示文摘The technology of three-dimensional(3D)printing emerged in the late 1970s and has since undergone considerable development to find numerous applications in mechanical engineering,industrial design,and biomedicine.In biomedical science,several studies have initially found that 3D printing technology can play an important role in the treatment of diseases in hepatopancreatobiliary surgery.For example,3D printing technology has been applied to create detailed anatomical models of disease organs for preoperative personalized surgical strategies,surgical simulation,intraoperative navigation,medical training,and patient education.Moreover,cancer models have been created using 3D printing technology for the research and selection of chemotherapy drugs.With the aim to clarify the development and application of 3D printing technology in hepatopancreatobiliary surgery,we introduce seven common types of 3D printing technology and review the status of research and application of 3D printing technology in the field of hepatopancreatobiliary surgery. | Wujiang SHI Jiangang WANG Jianjun GAO Xinlei ZOU Qingfu DONG Ziyue HUANG Jialin SHENG Canghai GUAN Yi XU Yunfu CUI Xiangyu ZHONG | 2024 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2024，25，2： | 0 |
| 8 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 10 | Deep Learning for Secure Transmission in Reconfigurable Intelligent Surface-Assisted Communications显示文摘This paper investigates the secure transmission for reconfigurable intelligent surface(RIS)-assisted wireless communication systems.In the studied model,one user connects to the access point via a RIS while an eavesdropper eavesdrops on the signal sent from the user to the access point.Therefore,it is necessary to design an appropriate RIS reflection vector to solve the eavesdropping problem.This problem is formulated as an optimization problem whose goal is to maximize the secure energy efficiency which is defined as the ratio of the secure rate to the total energy consumption of the system via jointly optimizing the RIS reflection reflector as well as the number of RIS elements,which results in a non-convex optimization problem that is intractable to solve by traditional methods.To tackle this issue,a new algorithm by leveraging the advance of the established deep learning(DL)technique is proposed so as to find the optimal RIS reflection vector and determine the optimal number of RIS reflection elements.Simulation results show that the proposed method reaches 96%of the optimal secure energy efficiency of the genie-aided algorithm. | Junhao Fang Xiangyu Zou Chongwen Huang Zhaohui Yang Yongjun Xu Xiao Chen Jianfeng Shi Mohammad Shikh-Bahaei | 2023 | Journal of Communications and Information Networks2023，8，2： | 0 |
