| 3 | Catalytic microwave assisted pyrolysis of aspen显示文摘The effect of catalysts on the microwave pyrolysis of aspen pellets was studied.A range of chlorides,nitrates and metal-oxides were added at 2%of the aspen mass(air dry aspen pellet weight basis).Chlorides in particular were found to favor liquid yield,especially the yield of water phase residue.Average liquid yield with added chlorides was 41%mass of the total biomass input,compared to 35%mass without catalyst.Metal-oxides were found to favor pyrolysis heavy oil,and thus total oil yield,since the yield of light oils seemed to be fairly constant.Nitrates were found to favor pyrolysis gas production.Pure light oils and light oils blended with diesel were found to be a potential diesel fuel substitute. | Johannes Moen Changyan Yang Bo Zhang Hanwu Lei Kevin Hennessy Yiqin Wan Zhiping Le Yuhuan Liu Paul Chen Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，4： | 5 |
| 4 | Fractionation and characterization of bio-oil from microwave-assisted pyrolysis of corn stover显示文摘Bio-oil from thermochemical conversion of biomass is a complex mixture of polar and non-polar compounds,and cannot be used directly as a combustion engine fuel due to its low heating value,high viscosity,chemical instability,and incomplete volatility.Mixed-solvent extraction was developed to fractionate bio-oils from microwave-assisted pyrolysis of corn stover to produce light oil(a mixture of light and inflammable fuel oil components from bio-oil)with low viscosity and low combustion residue,and high value chemicals.Different fractions from bio-oil were characterized using GC/MS and TG,and a major chemical(hydroxy-butanedioic acid diethyl ester)was separated. | Changyan Yang Bo Zhang Johannes Moen Kevin Hennessy Yuhuan Liu Xiangyang Lin Yiqin Wan Hanwu Lei Paul Chen Roger Ruan | 2010 | International Journal of Agricultural and Biological Engineering2010，3，3： | 4 |

| 6 | Selective immunoglobulin A deficiency(SIgAD)primarily leads to recurrent infections and autoimmune diseases:A retrospective study of Chinese patients in the past 40 years显示文摘Selective immunoglobulin A deficiency(SIgAD)is considered to be the most common human primary immune-deficiency disease in the world.However,the incidence in China is obviously lower than Caucasian races.The definition of SIgAD has changed over time with the progress of people’s understanding.The scientific community did not reach a consensus on the definition until 1999.As a result,many previously reported cases need to be excluded under the current definition.SIgAD can lead to several spectra of diseases including infections and autoimmune diseases.We retrospectively summarized the SIgAD patients in Peking Union Medical College Hospital(PUMCH),and summarized the Chinese SIgAD reported in China and abroad in past 40 years.Fourty three SIgAD patients were confirmed in the study,in which 9 were healthy without clinical symptoms.Of the 34 patients with clinical symptoms,recurrent infections were found in 29(85.3%)patients;13(38.2%)patients were with autoimmune diseases;6(17.6%)cases had allergic symptoms;3 patients(8.8%)were with tumors,only one case(2.9%)had a family history.Compared with other countries,sIgAD patients in China showed similar symptoms,but the rate of recurrent infections and autoimmune diseases were higher than some other countries;most of the allergic symptoms are drug allergy,different with the allergic sequelae reported in other countries,such as asthma,rhinitis,food allergy and atopic dermatitis;and it is rare to have family history in Chinese patients.We also figured out that more female SIgAD patients tend to have more autoimmune diseases than men(P=0.039). | Wei Wang Tianhao Yao Tianyi Zhang Meiying Quan Changyan Wang Chen Wang Lejia Zhang Xiaoyan Tang Shan Jian Hongmei Song | 2020 | Genes & Diseases2020，7，1： | 3 |
| 7 | Uniform single atomic Cu_(1)-C_(4)sites anchored in graphdiyne for hydroxylation of benzene to phenol显示文摘For single-atom catalysts(SACs),the catalyst supports are not only anchors for single atoms,but also modulators for geometric and electronic structures,which determine their catalytic performance.Selecting an appropriate support to prepare SACs with uniform coordination environments is critical for achieving optimal performance and clarifying the relationship between the structure and the property of SACs.Approaching such a goal is still a significant challenge.Taking advantage of the strong d-πinteraction between Cu atoms and diacetylenic in a graphdiyne(GDY)support,we present an efficient and simple strategy for fabricating Cu single atoms anchored on GDY(Cu_(1)/GDY)with uniform Cu_(1)-C_(4)single sites under mild conditions.The Cu atomic structure was confirmed by combining synchrotron radiation X-ray absorption spectroscopy,X-ray photoele ctron spectroscopy and density functional theory(DFT)calculations.The as-prepared Cu1/GDY exhibits much higher activity than state-of-the-art SACs in direct benzene oxidation to phenol with H_(2)O_(2)reaction,with turnover frequency values of 251 h^(-1)at room temperature and 1889 h^(-1)at 60℃,respectively.Furthermore,even with a high benzene conversion of86%,high phenol sele ctivity(96%)is maintaine d,which can be ascribed to the hydrophobic and oleophyllic surface nature of Cu1/GDY for benzene adsorption and phenol desorption.Both experiments and DFT calculations indicate that Cu_(1)-C_(4)single sites are more effective at activating H_(2)O_(2)to form Cu=O bonds,which are important active intermediates for benzene oxidation to phenol. | Jia Yu Changyan Cao Hongqiang Jin Weiming Chen Qikai Shen Peipei Li Lirong Zheng Feng He Weiguo Song Yuliang Li | 2022 | National Science Review2022，9，9： | 3 |
| 8 | Glial cells in neuronal development:recent advances and insights from Drosophila melanogaster显示文摘Glia outnumber neurons and are the most abundant cell type in the nervous system.Whereas neurons are the major carriers, transducers, and processors of information, glial cells, once considered mainly to play a passive supporting role, are now recognized for their active contributions to almost every aspect of nervous system development.Recently, insights from the invertebrate organism Drosophila melanogaster have advanced our knowledge of glial cell biology.In particular, findings on neuron-glia interactions via intrinsic and extrinsic mechanisms have shed light on the importance of glia during different stages of neuronal development.Here, we summarize recent advances in understanding the functions of Drosophila glia, which resemble their mammalian counterparts in morphology and function, neural stem-cell conversion, synapse formation, and developmental axon pruning.These discoveries reinforce the idea that glia are substantial players in the developing nervous system and further advance the understanding of mechanisms leading to neurodegeneration. | Jiayao Ou Yijing He Xi Xiao Tian-Ming Yu Changyan Chen Zongbao Gao Margaret S.Ho | 2014 | Neuroscience Bulletin2014，30，4： | 3 |
| 9 | Theoretical analysis of the limiting rate of phreatic evaporation for aeolian sandy soil in Taklimakan Desert显示文摘Phreatic evaporation is a great lose for shallow groundwater in the Taklimakan Desert. Given soil type and groundwater table, the limiting rate of phreatic evaporation is defined as the maximum of water transferred from groundwater to soil surface per unit time, which is a key parameter and control condition for phreatic evaporation model developing. The soil water characteristic curve for the aeolian sandy soil in the Taklimakan Desert was fitted with the least square method based on the formula of soil moisture characteristics curve proposed by Van Genuchten, using observed soil moisture and soil water suction data. The unsaturated hydraulic conductivity was determined by the instantaneous profile method in situ and the calculation formula for unsaturated hydraulic conductivity was established. According to the steady flow theory, the quasi-analytical solution of limiting rate of phreatic evaporation was derived on the basis of generalization of the formula of unsaturated hydraulic conductivity. The results show that the soil moisture characteristics in the Taklimakan Desert can be well described by Van Genuchten’s formula, and the limiting rate of phreatic evaporation declines by power function with the descending of groundwater table. | HU ShunJun LEI JiaQiang XU XinWen SONG YuDong TIAN ChangYan CHEN XiaoBin LI XiuChang | 2008 | Chinese Science Bulletin2008，53，S2： | 2 |
| 10 | Oxygen vacancies induced narrow band gap of BiOCl for efficient visible-light catalytic performance from double radicals显示文摘In this work,a high-efficiency photocatalytic BiOCl material with a visible light absorption range was successfully prepared by one-pot molecular self-assembly and particle recrystallization method at room temperature.In the process of crystal growth,tartaric acid,as a structure control agent,gradually transforms the stacked two-dimensional nano-sheet-like BiOCl into a hierarchical structure composed of petallike nano-sheets through hydrogen bonding.Besides,the acid etching of organic carboxylic acid on the crystal surface increases the number of micropores and mesopores,thereby the reaction interface.The thiourea(TU)molecules adsorbed on the BiOCl surface with a strong electronic effect introduce oxygen vacancies(OVs)under the condition of low oxygen content.The synergistic effect of hierarchical structure and OVs reduces the recombination of photogenerated carriers,but absorbs more O_(2)and OH−to generate a large number of superoxide radicals(·O_(2)−)and hydroxyl radicals(·OH)effectively.The photocatalytic performance of the synthesized BiOCl material has been significantly improved,and it can effectively degrade 94.15%of rhodamine B(RhB)within 20 min.Furthermore,90.95%of tetracycline(TC),93.76%of ciprofloxacin(CIP),and 85.53%of methyl orange(MO)can be removed in 80 min.Therefore,our work provides an effective method for preparing BiOCl with visible light catalytic activity,which,of course,can be used to treat and repair actual environmental problems under mild conditions. | Changyan Chen Ting Jiang Jianhua Hou Tingting Zhang Geshan Zhang Yongcai Zhang Xiaozhi Wang | 2022 | Journal of Materials Science & Technology2022，，19： | 2 |

| 16 | Dynamic evolution of nitrogen and oxygen dual-coordinated single atomic copper catalyst during partial oxidation of benzene to phenol显示文摘Single atom catalysts(SACs)with metal_(1)-N_(x)sites have shown promising activity and selectivity in direct catalytic oxidation of benzene to phenol.The reaction pathway is considered to be involving two steps,including a H_(2)O_(2)molecule dissociated on the metal single site to form the(metal_(1)-N_(x))=O active site,and followed by the dissociation of another H_(2)O_(2)on the other side of metal atom to form O=(metal_(1)-N_(x))=O intermediate center,which is active for the adsorption of benzene molecule via the formation of a C-O bond to form phenol.In this manuscript,we report a Cu SAC with nitrogen and oxygen dual-coordination(Cu1-N3O1 moiety)that doesn’t need the first H_(2)O_(2)activation process,as verified by both experimental and density function theory(DFT)calculations results.Compared with the counterpart nitrogen-coordinated Cu SAC(denoted as Cu1/NC),Cu SAC with nitrogen and oxygen dual-coordination(denoted as Cu1/NOC)exhibits 2.5 times higher turnover frequency(TOF)and 1.6 times higher utilization efficiency of H_(2)O_(2).Particularly,the coordination number(CN)of Cu atom in Cu1/NOC maintains four even after H_(2)O_(2)treatment and reaction.Combining DFT calculations,the dynamic evolution of single atomic Cu with nitrogen and oxygen dualcoordination in hydroxylation of benzene is proposed.These findings provide an efficient route to improve the catalytic performance through regulating the coordination environments of SACs and demonstrate a new reaction mechanism in hydroxylation of benzene to phenol reaction. | Weiming Chen Hongqiang Jin Feng He Peixin Cui Changyan Cao Weiguo Song | 2022 | Nano Research2022，15，4： | 1 |

| 18 | NO_(2) sensing with CdS nanowires at room temperature under green light illumination显示文摘Detection of ppb-level NO_(2) gas under atmosphere is urgent to meet the requirements of the rapidly developing internet of things.Compared with traditional sensing methods,light illumination has been considered as a key approach for excellent gas sensor performance under moderate conditions.Herein,we developed a green-light-assisted gas sensor based on cadmium sulfide nanowires(CdS NWs)that has good NO_(2) sensing capability at ambient temperature.The response values of NO_(2) are 236%and 11%to 10 ppm and 12.5 ppb,respectively.Furthermore,the CdS NWs sensor has a high selectivity for NO_(2) over a variety of interference gases,as well as good stability.The cleaning light activation and the sulfur vacancy-trapped charge behavior of CdS NWs are observed,which suggest a light-assisted sensing mechanism.These results suggest that light-induced charge separation behavior might significantly improve gas-sensing characteristics. | Peipei Li Hongqiang Jin Jia Yu Weiming Chen Runqing Zhao Changyan Cao Weiguo Song | 2022 | Materials Futures2022，1，2： | 0 |
| 19 | In-situ doping nickel single atoms in two-dimensional MXenes analogue support for room temperature NO_(2) sensing显示文摘MXenes are promising supports for anchoring metal single atoms due to their versatile composition,well-defined nanostructures,and suitable conductivity.However,metal single atoms are usually coordinated with surface terminal groups(-O,-OH,-Cl,etc.)of MXenes via conventional wet-impregnation,resulting in limited electronic structure modification.Through a NiCl2 molten salt etching method,we observed that Ni single atoms could be in-situ doped in the lattice of MXenes analogue TiC_(0.5)N_(0.5) support(denoted as Ni1/TiC0.5N0.5),resulting in much larger charge transfer from Ni atoms to adjacent Ti atoms,and thus increasing the electronic density of these Ti atoms.When used for NO_(2) sensing,Ni_(1)/TiC_(0.5)N_(0.5) exhibited excellent response sensitivity(ultra-low limit of detection~10 ppb),selectivity,and good stability at room temperature.This study provides an effective strategy for producing MXenes analogue supported metal single atoms for potential application in gas sensing. | Weiming Chen Peipei Li Jia Yu Peixin Cui Xiaohu Yu Weiguo Song Changyan Cao | 2022 | Nano Research2022，15，10： | 0 |
| 20 | Insulin receptor is implicated in triple-negative breast cancer by decreasing cell mobility显示文摘Triple-negative breast cancer(TNBC)has a poor prognosis and typically earlier onset of metastasis in comparison with other breast cancer subtypes.It has been reported that insulin receptor(INSR)is downregulated in TNBC,however,its clinical significance and functions in TNBC remain to be elucidated.In this study,we found that INSR expression was significantly downregulated in TNBC,and overexpression of INSR suppressed cell migration and invasion in TNBC.In addition,the survival rate of breast cancer patients with low INSR expression was lower than that of patients with high INSR expression.INSR expression was significantly correlated with lymph node metastasis,clinical tumor stages,ER status,PR status,and the proliferation index Ki-67 expression.In summary,our study suggests that INSR may serve as a biomarker for breast cancer prognosis and it may be a potential target for TNBC treatment. | Ying Yang Xiang Chen Changyan Ma | 2021 | The Journal of Biomedical Research2021，35，3： | 0 |
