| 1 | La/Ce-codoped Bi_2O_3 composite photocatalysts with high photocatalytic performance in removal of high concentration dye显示文摘A series of La/Ce-codoped Bi_2O_3 composite photocatalysts were fabricated via hydrothermal–calcination process. The as-prepared products were intensively characterized by some physicochemical characterizations like N_2 physical adsorption, X-ray powder diffraction(XRD), scanning electron microscope(SEM), transmission electron microscope(TEM), UV–Vis diffuse reflectance(UV–Vis DRS), Fourier transform infrared spectroscopy(FT-IR),photoelectrochemical measurements, and photoluminescence(PL) spectroscopy. The characterization results indicated that La and Ce doping induced obvious crystal phase transformation in Bi_2O_3, from monoclinic to tetragonal phase. La and Ce codoping also gave rise to the obvious synergetic effects, e.g., the lattice contraction of Bi_2O_3, the decrease of crystal size and the increase of surface area. The photocatalytic performance of the prepared catalysts was evaluated by removal of dye acid orange II with high concentration under visible light irradiation. Results showed that La/Ce-codoped Bi_2O_3 displayed much higher photocatalytic performance than that of bare Bi_2O_3, single La or Ce doped Bi_2O_3 samples. The superior photocatalytic activity was mainly attributed to the improved texture and surface properties and the synergistic effects of La and Ce codoping on suppressing the recombination of photo-generated electrons(e^-) and holes(h^+). | Shuangshuang Xue Hongbo He Qizhe Fan Changlin Yu Kai Yang Weiya Huang Yang Zhou Yu Xie | 2017 | Journal of Environmental Sciences2017，29，10： | 7 |

| 4 | Optical visualization and polarized light absorption of the single-wall carbon nanotube to verify intrinsic thermal applications显示文摘The predicted extraordinary properties of carbon nanotubes(CNTs)from theoretical calculations have great potential for many applications.However,reliable experimental determination of intrinsic properties at the single-tube level is currently a matter of concern,and many challenges remain because of the unhandled and nanoscale size of individual nanotubes.Here,we demonstrated a prototype to detect the intrinsic thermal conductivity of the single-wall carbon nanotube(SWCNT)and verify the significant non-resonant optical absorption behavior on tiny nanotubes by integrating the nanotube and ice into a new core-shell design.In particular,a reversible optical visualization method based on the individual suspended ultra-long SWCNT was first developed by wrapping a nanotube with ice in the cryogenic air environment.The light-induced thermal effect on the hybrid core-shell structure was used tomelt the ice shell,which subsequently acted as a temperature sensor to verify the intrinsic thermal conductivity of the core-like nanotube.More interestingly,we successfully determined for the first time the thermal response phenomenon of the tiny absorption cross section in SWCNT in the vertical-polarization configuration and the significant non-resonant absorption behavior in the parallel-polarization configuration.These investigations will provide a better understanding for the unique optical behaviors of CNT and enable the detection of intrinsic properties of various one-dimensional nanostructures such as nanotubes,nanowires,and nanoribbons. | Xiao Zhang Li Song Le Cai Xuezeng Tian Qiang Zhang Xiaoying Qi Wenbin Zhou Nan Zhang Feng Yang Qingxia Fan Yanchun Wang Huaping Liu Xuedong Bai Weiya Zhou Sishen Xie | 2015 | Light(Science & Applications)2015，4，1： | 2 |
| 5 | Aromatic inorganic acid radical显示文摘Stable radicals are challenging to prepare due to their intrinsic high reactivity.Herein,three trisphenolamine radicals were readily synthesized and exhibited unexpected thermal/electrochemical stability and semiconductor property.These three nitroxide radicals could be considered as a class of aromatized nitro groups or HNO3 derivatives.The closed-shell nitro-like and open-shell nitroxide resonance structure contribute to their outstanding stability.Furthermore,the tunable ground states,extremely low band gap and p-type charge transport properties were systematically investigated.More importantly,the work presents the concept of aromatic inorganic acid radical(AIAR)and aggregation-induced radical(AIR)mechanism to understand the intrinsic structureproperty relationship of these radicals.In addition,we provide a novel strategy for the design of stable and low bandgap radicals for organic electronics,magnetics,spintronics,etc. | Jiawen Zhou Weiya Zhu Miao Zeng Qingqing Yang Ping Li Linfeng Lan Junbiao Peng Yuan Li Fei Huang Yong Cao | 2019 | Science China Chemistry2019，62，12： | 1 |

| 10 | High value-added fluorescence upconversion agents-assisted nanosemiconductors for efficient wide spectral response photocatalysis:Exerting energy transfer effect and applications显示文摘The design of the photocatalytic materials has made a great of remarkable progress in the area of the enhancement photocatalytic activity,but there are still lots of problems such as wide band gap,low utilization of sunlight,low quantum efficiency and poor stability,which further limit the extensive practical applications.Thus,it is a hot research topic and key scientific problem to be solved that how to design and prepare the catalysts,which can respond to visible and near-infrared light in sunlight.Inspired by efficient nonlinear optical upconversion materials,upconversion-based nanocomposites can indirectly broaden the absorption ranges of semiconductors by co nverting the captured long-band visible and near-infrared incident light into high-energy short-band visible or ultraviolet light,which can be adopted as the promising candidate in wide-spectral-light-activating photocatalytic materials coupling with conventional semiconductors.According to our recent works and literature reports,recent review summarizes the research progress of photocatalytic materials with upconversion effect on photolysis of water for hydrogen production,degradation of organic and inorganic pollutants,reduction of CO_(2) and photodynamic therapy.The prepared nanocomposites can suppress the recombination of electrons and holes,and greatly improve the photocatalytic efficiency by the synergistic effect.It maybe stimulates a great interest in rational design and preparation of efficient full-spectrum photocatalytic systems and their wide application in solar energy conversion. | Kailian Zhang Man Zhou Changlin Yu Xiaoxiao Li Kai Yang Shi Yang Wenxin Dai Weiya Huang Qizhe Fan Lihua Zhu | 2021 | Journal of Rare Earths2021，39，3： | 1 |
| 11 | Omicron variants breakthrough infection elicited higher specific memory immunity than third dose booster in healthy vaccinees显示文摘Homologous booster,heterologous booster,and Omicron variants breakthrough infection(OBI)could improve the humoral immunity against Omicron variants.Questions concerning about memory B cells(MBCs)and T cells immunity against Omicron variants,features of long-term immunity,after booster and OBI,needs to be explored.Here,comparative analysis demonstrate antibody and T cell immunity against ancestral strain,Delta and Omicron variants in Omicron breakthrough infected patients(OBIPs)are comparable to that in Ad5-nCoV boosted healthy volunteers(HVs),higher than that in inactivated vaccine(InV)boosted HVs.However,memory B cells(MBCs)immunity against Omicron variants was highest in OBIPs,followed by Ad5-nCoV boosted and InV boosted HVs.OBIPs and Ad5-nCoV boosted HVs have higher classical MBCs and activated MBCs,and lower naïve MBCs and atypical MBCs relative to both vaccine boosted HVs.Collectively,these data indicate Omicron breakthrough infection elicit higher MBCs and T cells against SARS-CoV-2 especially Omicron variants relative to homologous InV booster and heterologous Ad5-nCoV booster. | Pei Yu Zijian Liu Zhuoqi Zhu Jiaqing Yang Min Deng Mingxiao Chen Changchun Lai Weiya Kong Shilong Xiong Li Wan Weikang Mai Lu Chen Yu Lei Shahzad Akbar Khan Jianfeng Ruan An Kang Xuguang Guo Qiang Zhou Wenrui Li Zheng Chen Yuemei Liang Pingchao Li Lei Zhang Tianxing Ji | 2023 | Virologica Sinica2023，38，2： | 0 |
| 12 | Spatially resolved expression landscape and generegulatory network of human gastric corpus epithelium显示文摘Molecular knowledge of human gastric corpus epithelium remains incomplete.Here,by integrated analyses using single-cell RNA sequencing(scRNA-seq),spatial transcriptomics,and single-cell assay for transposase accessible chromatin sequencing(scATAC-seq)techniques,we uncovered the spatially resolved expression landscape and gene-regulatory network of human gastric corpus epithelium.Specifically,we identified a stem/progenitor cell population in the isthmus of human gastric corpus,where EGF and WNT signaling pathways were activated.Meanwhile,LGR4,but not LGR5,was responsible for the activation of WNT signaling pathway.Importantly,FABP5 and NME1 were identified and validated as crucial for both normal gastric stem/progenitor cells and gastric cancer cells.Finally,we explored the epigenetic regulation of critical genes for gastric corpus epithelium at chromatin state level,and identified several important cell-type-specific transcription factors.In summary,our work provides novel insights to systematically understand the cellular diversity and homeostasis of human gastric corpus epithelium in vivo. | Ji Dong Xinglong Wu Xin Zhou Yuan Gao Changliang Wang Wendong Wang Weiya He Jingyun Li Wenjun Deng Jiayu Liao Xiaotian Wu Yongqu Lu Antony KChen Lu Wen Wei Fu Fuchou Tang | 2023 | Protein & Cell2023，14，6： | 0 |
| 13 | Conductance and dielectric properties of pure C_(60) single crystal显示文摘THE C60 is the third stable allotrope of carbon. Much attention has been focused on C60 since it has unique properties. Much work has been carried out on it, such as the preparation of large quantities of C60, the structure studies of C60, the superconducting alkali-metal-C60 compounds, the growth of pure C60 single crystal. There is still a lot of work to do in detail, but because the size of the single ctystal is not large enough, there is some difficulty in research, for example, the electric and optical properties of the C60 single crystal. | YANG Guoquan, WANG Gang, WEN Weijia, ZHOU Weiya, LU Kunquan and XIE Sisheng1.

| 14 | Mixed-phase Mesoporous TiO2 Film for High Efficiency Perovskite Solar Cells显示文摘Mesoporous scaffold structures have played great roles in halide perovskite solar cells(PSCs),due to the excellent photovoltaic performance and commercial perspective of mesoporous PSCs.Here,we reported a mixed-phase TiO2 mesoporous film as an efficient electron transport layer(ETL)for mesoporous perovskite solar cells.Due to the improved crystal phase,fihn thickness and nanopartMe size of TiO2 layer,which were controlled by varying the one-step hydrothermal reaction time and annealing time,the PSCs exhibited an outstanding short circuit photocurrent density of 25.27 mA/cm^2,and a maximum power conversion efficiency(PCE)of 19.87%.It is found that the ultra-high Jsc attributes to the excellent film quality,light capturing and excellent electron transport ability of mixed-phase TiO2 mesoporous film.The results indicate that mix-phase mesoporous metal oxide fihns could be a promising candidate for producing effective ETLs and high efficiency PSCs. | XIANG Yan ZHUANG Jia MA Zhu LU Honglin XIA Haoran ZHOU Weiya ZHANG Tao LI Haimin | 2019 | Chemical Research in Chinese Universities2019，35，1： | 0 |

| 16 | Diameter-dependent photoelectric performances of semiconducting carbon nanotubes/perovskite heterojunctions显示文摘The heterojunction of single-wall carbon nanotubes(SWCNTs)and perovskite quantum dots(QDs)shows excellent photodetection performances due to the combination of the advantages of high carrier mobility of SWCNTs and high absorption coefficient of perovskite QDs.However,the band structure of a SWCNT is determined by its atomic arrangement structure.How the structure of SWCNTs affects the photoelectric performance of the composite film remains elusive.Here,we systematically explored the diameter effect of SWCNTs with different bandgaps on the photodetection performances of SWCNTs/perovskite QDs heterojunction films by integrating semiconducting SWCNTs(s-SWCNTs)with different diameters with CsPbBr3 QDs.The results show that with an increase in diameter of s-SWCNTs,the heterojunction exhibits increasing responsivity(R),detectivity(D*),and faster response time.The great improvement in the optoelectronic performances of devices should be attributed to the higher carrier mobility of larger-diameter SWCNT films and the increasing built-in electric field at the heterojunction interfaces between larger-diameter SWCNTs and CsPbBr3 QDs,which enhances the separation of the photogenerated excitons and the transport of the resulted carriers in SWCNT films. | Yayang Yu Wenke Wang Xiao Li Linhai Li Shilong Li Xiaojun Wei Weiya Zhou Jing Lin Yang Huang Huaping Liu | 2023 | Nano Research2023，16，11： | 0 |
| 17 | Enhanced exciton diffusion from interlayer charge-transfer transitions in PtSe2/MoSe_(2) van der Waals heterojunction显示文摘Artificial van der Waals(vdWs)heterostructures offer unprecedented opportunities to explore and reveal novel synergistic electronic and optical phenomena,which are beneficial for the development of novel optoelectronic devices at atomic limits.However,due to the damage caused by the device fabrication process,their inherent properties such as carrier mobility are obscured,which hinders the improvement of device performance and the incorporation of vdWs materials into next-generation integrated circuits.Herein,combining pump-probe spectroscopic and scanning probe microscopic techniques,the intrinsic optoelectronic properties of PtSe_(2)/MoSe_(2)heterojunction were nondestructively and systematically investigated.The heterojunction exhibits a broad-spectrum optical response and maintains ultrafast carrier dynamics(interfacial charge transfer~0.8 ps and carrier lifetime~38.2 ps)simultaneously.The in-plane exciton diffusion coefficient of the heterojunction was extracted(19.4±7.6 cm^(2)∙s^(−1)),and its exciton mobility as high as 756.8 cm^(2)∙V−1∙s^(−1)was deduced,exceeding the value of its components.This enhancement was attributed to the formation of an n-type Schottky junction between PtSe_(2)and MoSe_(2),and its built-in electric field assisted the ultrafast transfer of photogenerated carriers from MoSe_(2)to PtSe_(2),enhancing the in-plane exciton diffusion of the heterojunction.Our results demonstrate that PtSe_(2)/MoSe_(2)is suitable for the development of broadspectrum and sensitive optoelectronic devices.Meanwhile,the results contribute to a fundamental understanding of the performance of various optoelectronic devices based on such PtSe_(2)two-dimensional(2D)heterostructures. | Jiarong Wang Dawei He Zhiying Bai Guili Li Jinxuan Bai Keqin Liu Fangying Ren Xiaojing Liu Jiaqi He Weiya Zhou Jianlin Sun Yongsheng Wang Xiaoxian Zhang Yuchao Yang | 2023 | Nano Research2023，16，11： | 0 |
| 18 | Enhanced composite thermal conductivity by percolated networks of in-situ confined-grown carbon nanotubes显示文摘Despite the ever-increasing demand of nanofillers for thermal enhancement of polymer composites with higher thermal conductivity and irregular geometry,nanomaterials like carbon nanotubes(CNTs)have been constrained by the nonuniform dispersion and difficulty in constructing effective three-dimensional(3D)conduction network with low loading and desired isotropic or anisotropic(specific preferred heat conduction)performances.Herein,we illustrated the in-situ construction of CNT based 3D heat conduction networks with different directional performances.First,to in-situ construct an isotropic percolated conduction network,with spherical cores as support materials,we developed a confined-growth technique for CNT-core sea urchin(CNTSU)materials.With 21.0 wt.%CNTSU loading,the thermal conductivity of composites reached 1.43±0.13 W/(m·K).Secondly,with aligned hexagonal boron nitride(hBN)as an anisotropic support,we constructed CNT-hBN aligned networks by in-situ CNT growth,which improved the utilization efficiency of high density hBN and reduced the thermal interface resistance between matrix and fillers.With~8.5 wt.%loading,the composites possess thermal conductivity up to 0.86±0.14 W/(m·K),374%of that for neat matrix.Due to the uniformity of CNTs in hBN network,the synergistic thermal enhancement from one-dimensional(1D)+two-dimensional(2D)hybrid materials becomes more distinct.Based on the detailed experimental evidence,the importance of purposeful production of a uniformly interconnected heat conduction 3D network with desired directional performance can be observed,particularly compared with the traditional direct-mixing method.This study opens new possibilities for the preparation of high-power-density electronics packaging and interfacial materials when both directional thermal performance and complex composite geometry are simultaneously required. | Xiao Zhang Wei Tan Tian Carey Bo Wen Delong He Adrees Arbab Alex Groombridge Fiona Smail Jean de La Verpilliere Chengning Yao Yanchun Wang Xiaojun Wei Huaping Liu Sishen Xie Felice Torrisi Michael De Volder Weiya Zhou Adam Boies | 2023 | Nano Research2023，16，11： | 0 |
