| 1 | Catalytic conversion of lignocellulosic biomass into chemicals and fuels显示文摘In the search of alternative resources to make commodity chemicals and transportation fuels for a low carbon future,lignocellulosic biomass with over 180-billion-ton annual production rate has been identified as a promising feedstock.This review focuses on the state-of-the-art catalytic transformation of lignocellulosic biomass into value-added chemicals and fuels.Following a brief introduction on the structure,major resources and pretreatment methods of lignocellulosic biomass,the catalytic conversion of three main components,i.e.,cellulose,hemicellulose and lignin,into various compounds are comprehensively discussed.Either in separate steps or in one-pot,cellulose and hemicellulose are hydrolyzed into sugars and upgraded into oxygen-containing chemicals such as 5-HMF,furfural,polyols,and organic acids,or even nitrogen-containing chemicals such as amino acids.On the other hand,lignin is first depolymerized into phenols,catechols,guaiacols,aldehydes and ketones,and then further transformed into hydrocarbon fuels,bioplastic precursors and bioactive compounds.The review then introduces the transformations of whole biomass via catalytic gasification,catalytic pyrolysis,as well as emerging strategies.Finally,opportunities,challenges and prospective of woody biomass valorization are highlighted. | Weiping Deng Yunchao Feng Jie Fu Haiwei Guo Yong Guo Buxing Han Zhicheng Jiang Lingzhao Kong Changzhi Li Haichao Liu Phuc T.T.Nguyen Puning Ren Feng Wang Shuai Wang Yanqin Wang Ye Wang Sie Shing Wong Kai Yan Ning Yan Xiaofei Yang Yuanbao Zhang Zhanrong Zhang Xianhai Zeng Hui Zhou | 2023 | Green Energy & Environment2023，8，1： | 6 |

| 3 | Using seismic surveys to investigate sediment distribution and to estimate burial fluxes of OC, N, and P in a canyon reservoir显示文摘As a high-precision survey method,seismic surveying has been increasingly applied to inland water research,although its application to artificial reservoirs has remained limited.As a special artificial water body,reservoirs have important effects on the fluvial transport of material from land to ocean,and inevitably have complex terrain which can complicate and distort the results of seismic surveys.Therefore,there are still some problems need to be resolved in the application of seismic surveys in reservoirs with complex terrain.For this study,the Dongfeng Reservoir located in the upper reaches of the Wujiang River was chosen as an example to test the seismic survey method.Our testing showed that(1)because of the complex underwater terrain,the signal-to-noise ratio of the echo signal in canyon reservoir is low,making it difficult to determine sediment layers thicknesses in some areas;and(2)due to the large spatial heterogeneity of sediment distribution,insufficient density of cross-sections can lead to inaccurate interpolation results.To improve the accuracy of calculations,a mathematical method was used.Ultimately,the total burial mass of sediment was estimated at 2.85 x 107 tons,and the average burial rates of total organic carbon,total phosphorus,and total nitrogen were estimated at 0.194,0.011,and 0.014 g cm-2 year-1,respectively.These values were close to the results of previous studies and hydrographic station data,indicating that seismic survey can be a reliable and efficient method for the mapping of reservoirs. | Ningxiao Yu Yong Qin Feng Hao Yunchao Lang Fushun Wang | 2019 | Acta Geochimica2019，38，6： | 3 |
| 4 | Genomic evidence of lung carcinogenesis associated with coal smoke in Xuanwei area, China显示文摘Xuanwei area, in southwestern China,harbors the highest female lung cancer rate in the country(Supplementary Table 1) [1]. Epidemiological studies have shown that lung cancer incidence in Xuanwei area is associated with the use of different types of local coal for household cooking and heating [2]. The genomic landscape of Xuanwei female adenocarcinoma(XWFA), the most distinctive feature of lung cancer in Xuanwei, has yet to be elucidated systematically. Here,we provide the fundamental resource of genomic datasets for further exploration of XWFA molecular mechanisms and development of targetable therapy. | Honglei Zhang Chao Liu Li Li Xu Feng Qing Wang Jihua Li Shaobin Xu Shuting Wang Qianlu Yang Zhenghai Shen Jinhua Su Xiaosan Su Ruifen Sun Xuhong Zhou Junliang Wang Yongchun Zhou Baowei Jiao Wanbao Ding Xianbao Cao Yue Wang Yunchao Huang Lianhua Ye | 2021 | National Science Review2021，8，12： | 2 |
| 5 | Detailed modeling of aluminum particle combustion——From single particles to cloud combustion in Bunsen flames显示文摘A numerical model for aluminum cloud combustion which includes the effects of interphase heat transfer,phase change,heterogeneous surface reactions,homogeneous combustion,oxide cap growth and radiation within the Euler–Lagrange framework is proposed.The model is validated in single particle configurations with varying particle diameters.The combustion process of a single aluminum particle is analyzed in detail and the particle consumption rates as well as the heat release rates due to the various physical/chemical sub-models are presented.The combustion time of single aluminum particles predicted by the model are in very good agreement with empirical correlations for particles with diameters larger than 10μm.The prediction error for smaller particles is noticeably reduced when using a heat transfer model that is capable of capturing the transition regime between continuum mechanics and molecular dynamics.The predictive capabilities of the proposed model framework are further evaluated by simulating the aluminum/air Bunsen flames of Mc Gill University for the first time.Results show that the predicted temperature distribution of the flame is consistent with the experimental data and the double-front structure of the Bunsen flame is reproduced well.The burning rates of aluminum in both single particle and particle cloud configurations are calculated and compared with empirical correlations.Results show that the burning rates obtained from the present model are more reasonable,while the correlations,when embedded in the Euler–Lagrange context,tend to underestimate the burning rate in the combustion stage,particularly for the considered fuel-rich flames. | Jiarui ZHANG Oliver T.STEIN Tien D.LUU Ali SHAMOONI Zhixun XIA Zhenbing LUO Likun MA Yunchao FENG Andreas KRONENBURG | 2022 | Chinese Journal of Aeronautics2022，35，5： | 2 |
| 6 | One-pot synthesis of 2,5-bis(hydroxymethyl)furan from biomass derived 5-(chloromethyl)furfural in high yield显示文摘5-(Chloromethyl)furfural(CMF),as a new platform molecular,has become a hot topic in the field of biorefinery.Herein,the one-pot conversion of CMF to 2,5-bis(hydroxymethyl)furan(BHMF)in the water phase was demonstrated for the first time.A 91%BHMF yield was obtained over Ru/Cu Oxcatalyst,and BHMF was mainly produced by the consecutive hydrolysis and hydrogenation of CMF with 5-hydroxymethylfurfural(HMF)as an intermediate.Kinetic studies revealed that the conversion of HMF to BHMF was the rate-determining step.Remarkably,the characterizations and density functional theory(DFT)calculations further revealed the lower electron density of Ru NPs in Ru/Cu Oxcatalyst,resulting in a larger adsorption energy and a smaller free energy difference for the formation of alcohols.The present findings offered a new pathway for biomass-derived diol production through CMF as a potential source. | Binglin Chen Yunchao Feng Sen Ma Weizhen Xie Guihua Yan Zheng Li Jonathan Sperry Shuliang Yang Xing Tang Yong Sun Lu Lin Xianhai Zeng | 2023 | Journal of Energy Chemistry2023，，1： | 1 |

| 9 | Multiplexed imaging of tumor immune microenvironmental markers in locally advanced or metastatic non-small-cell lung cancer characterizes the features of response to PD-1 blockade plus chemotherapy显示文摘Background:Although programmed cell death 1(PD-1)blockade plus chemotherapy can significantly prolong the progression-free survival(PFS)and overall survival(OS)in first-line settings in patients with driver-negative advanced non-small-cell lung cancer(NSCLC),the predictive biomarkers remain undetermined.Here,we investigated the predictive value of tumor immune microenvironmental marker expression to characterize the response features to PD-1 blockade plus chemotherapy.Methods:Tumor tissue samples at baseline were prospectively collected from 144 locally advanced or metastatic NSCLC patients without driver gene alterations who received camrelizumab plus chemotherapy or chemotherapy alone.Tumor immune microenvironmental markers,including PD-1 ligand(PDL1),CD8,CD68,CD4 and forkhead box P3,were assessed using multiplex immunofluorescence(mIF)assays.Kaplan-Meier curveswere used to determine treatment outcome differences according to their expression status.Mutational profiles were compared between tumors with distinct expression levels of these markers and their combinations.Results:Responders had significantly higher CD8/PD-L1(P=0.015)or CD68/PD-L1 co-expression levels(P=0.021)than non-responders in the camrelizumab plus chemotherapy group,while no difference was observed in the chemotherapy group.Patients with high CD8/PD-L1 or CD68/PD-L1 co-expression level was associated with significantly longer PFS(P=0.002,P=0.024;respectively)and OS(P=0.006,P=0.026;respectively)than those with low co-expression in camrelizumab plus chemotherapy group.When comparing survival in the camrelizumab plus chemotherapy with chemotherapy by CD8/PD-L1 co-expression stratification,significantly better PFS(P=0.003)and OS(P=0.032)were observed in high co-expression subgroups.The predictive value of CD8/PD-L1 and CD68/PD-L1 co-expression remained statistically significant for PFS and OS when adjusting clinicopathological features.Although the prevalence of TP53 or KRAS mutations was similar between patients with and without CD8/PD-L1 or CD68/PD-L1 co-expression,the positive groups had a significantly higher proportion of TP53/KRAS co-mutations than the negative groups(both 13.0%vs.0.0%,P=0.023).Notably,enriched PI3K(P=0.012)and cell cycle pathway(P=0.021)were found in the CD8/PD-L1 co-expression group.Conclusion:Tumor immune microenvironmental marker expression,especially CD8/PD-L1 or CD68/PD-L1 co-expression,was associated with the efficacy of PD-1 blockade plus chemotherapy as first-line treatment in patients with advanced NSCLC. | Fengying Wu Tao Jiang Gongyan Chen Yunchao Huang Jianying Zhou Lizhu Lin Jifeng Feng Zhehai Wang Yongqian Shu Jianhua Shi Yi Hu Qiming Wang Ying Cheng Jianhua Chen Xiaoyan Lin Yongsheng Wang Jianan Huang Jiuwei Cui Lejie Cao Yunpeng Liu Yiping Zhang Yueyin Pan Jun Zhao LiPing Wang Jianhua Chang Qun Chen Xiubao Ren Wei Zhang Yun Fan Zhiyong He Jian Fang Kangsheng Gu Xiaorong Dong Tao Zhang Wei Shi Jianjun Zou Xuejuan Bai Shengxiang Ren Caicun Zhou | 2022 | Cancer Communications2022，42，12： | 1 |

| 11 | dbDEMC 3.0:Functional Exploration of Differentially Expressed miRNAs in Cancers of Human and Model Organisms显示文摘MicroRNAs(miRNAs)are important regulators in gene expression.The dysregulation of miRNA expression is widely reported in the transformation from physiological to pathological states of cells.A large number of differentially expressed miRNAs(DEMs)have been identified in various human cancers by using high-throughput technologies,such as microarray and miRNAseq.Through mining of published studies with high-throughput experiment information,the database of DEMs in human cancers(dbDEMC)was constructed with the aim of providing a systematic resource for the storage and query of the DEMs.Here we report an update of the dbDEMC to version 3.0,which contains two-fold more data entries than the second version and now includes also data from mice and rats.The dbDEMC 3.0 contains 3268 unique DEMs in 40 different cancer types.The current datasets for differential expression analysis have expanded to 9 generalized categories.Moreover,the current release integrates functional annotations of DEMs obtained by using experimentally validated targets.The annotations can be of great benefit to the intensive analysis of the roles of DEMs in cancer.In summary,dbDEMC 3.0 provides a valuable resource for characterizing molecular functions and regulatory mechanisms of DEMs in human cancers.The dbDEMC 3.0 is freely accessible at https://www.biosino.org/dbDEMC. | Feng Xu Yifan Wang Yunchao Ling Chenfen Zhou Haizhou Wang Andrew E.Teschendorff Yi Zhao Haitao Zhao Yungang He Guoqing Zhang Zhen Yang | 2022 | Genomics, Proteomics & Bioinformatics2022，20，3： | 1 |
| 12 | Effect of carbon dioxide concentration on the combustion characteristics of boron agglomerates in oxygen-containing atmospheres显示文摘In ramjet combustion chambers,carbon dioxide(CO_(2))produced by the combustion of carbonaceous fuel enters the chamber together with boron agglomerates.In order to investigate the effect of CO_(2)concentration present in an oxygen-containing atmosphere on the combustion characteristics and oxidation mechanisms of boron agglomerates,we used a laser ignition system,an X-ray diffractometer(XRD),and a thermogravimetric-differential scanning calorimetry(TG-DSC)combined thermal analysis system.Single-particle boron was tested in the laser-ignition experiments as the control group.The ignition experiment results showed that with a fixed O2 concentration of 20%,when the particle temperature reaches the melting point of boron,increasing CO_(2)content causes the combustion process of boron agglomerates to transition from single-particle molten droplet combustion to porous-particle combustion.Furthermore,XRD analysis results indicated that the condensed-phase combustion products(CCPs)of boron particles in a mixed atmosphere of O2 and CO_(2)contained B4C,which is responsible for the porous structure of the particles.At temperatures below 1200℃,the addition of CO_(2)has no obvious promotion effect on boron exothermic reaction.However,in the laser-ignition experiment,when the oxygen concentration was fixed at 20%while the CO_(2)concentration increased from 0%to 80%,the maximum temperature of boron agglomerates rose from 2434 to 2573 K,the self-sustaining combustion time of single-particle boron decreased from 396 to 169 ms,and the self-sustaining combustion time of boron agglomerates decreased from 198 to 40 ms.This study conclusively showed that adding CO_(2)to an oxygen-containing atmosphere facilitates boron reaction and consumption pathways,which is beneficial to promoting exothermic reaction of boron agglomerates at relatively high temperatures. | Lian DUAN Zhixun XIA Yunchao FENG Binbin CHEN Jiarui ZHANG Likun MA | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，11： | 0 |
