2Paleomagnetic results of Late Paleozoic rocks from northern Qiangtang Block in Qinghai-Tibet Plateau, China显示文摘Tectonic evolution of the Tethys and the boundary between the Gondwanaland and the Eurasia during the Carboniferous and Permian remain hotly debated. Qiangtang region in the Qinghai-Tibet Plateau may be a key place to study these problems. A paleomagnetic study was conducted on the Late Paleozoic rocks in the northern Qiangtang region (33.7°N, 86.7°W), Tibet. Two sites (21 samples) in the Upper Carboniferous, eleven sites (101 samples) in the Permian, and two sites (16 samples) in the Lower Triassic were investigated. The rock magnetic data revealed hematite and magnetite as the main magnetic carriers. In stepwise thermal demagnetization and/or combined alternating field (AC) demagnetization, two characteristic components in the majority of the samples were identified as (1) the Low-temperature Component (LTC), characterized by northerly decli- nation and moderate to steep inclination, corresponding to a pole position overlay with the present North Pole. A minority of the samples present single component, and their directions are the same as (2) the High-temperature Component (HTC) of double components. The combined single-component and HTC data of the Permian can pass the R-test at 95% level and the F-test at 99% level, as well as the BC-test. The pole position from the Late Carboniferous is at 31.8°S, 45.7°E with dp=2.1, dm=3.9, that from the Early and Middle (Late) Permian is at 31.7°S, 46.8°E with dp=9.2, dm=16.9 (34.4°N, 54.1°E with dp=6.9, dm=12.5) respectively, and that from the Early Triassic is at 16.9°S, 22.5°E with dp=4.9, dm=9.2. These pole positions are different from the other poles for the Qiangtang Block, which suggests the single-component and HTC directions are probably a primary magnetization and the northern Qiangtang Block was paleogeographically situated at low latitudes in the Northern Hemisphere in the Late Paleozoic.CHENG Xin WU HanNing GUO Qiang HOU BaoNing XIA LingYan WANG HaiJun DIAO ZongBao HUO FeiFei JI WenHua LI RongShe CHEN ShouJian ZHAO ZhenMing LIU XiaoJi 2012Science China Earth Sciences2012,55,1:9
3Cocrystallization of N-donor type compounds with 5-sulfosalicylic acid:The effect of hydrogen-bonding supramolecular architectures显示文摘Benzotriazole,N,N'-dimethylpiperazine and N-methylpiperazine were applied to crystallize with 5-sulfosalicylic acid(5-H2SSA),affording three new binary molecular cocrystals [(C6H6N3+).(C7H5O6S-)].H2O(1),[(C6H16N22+)1/2.(C7H5O6S-)].H2O(2) and [(C5H14N22+).(C7H5O6S-)2].3H2O(3) under general conditions.Proton-transferring occurs from acid to nitrogen of N-donor compounds in all compounds 1,2 and 3.Analysis of the hydrogen-bonding synthons and their effects on crystal packing were also presented in the context of crystal engineering and host-guest chemistry.In compound 1,1-D infinite chains are extended to a 2-D layered architecture via strong O-H...O hydrogen bonds and then to a 3-D network by N-H...O interactions.Compound 2 and 3 both have the 1-D chain which is formed by O-H...O bonds and weak C-H...O hydrogen bonds.A common intramolecular S(6) [synthon I] ring is formed by the hydroxyl with the carboxyl group in all three compounds.WANG Lei XU LingYan XUE RuiFeng LU XiFeng CHEN RuiXin TAO XuTang 2012Science China Chemistry2012,55,1:8
4An Energy Efficient Design for UAV Communication With Mobile Edge Computing显示文摘This paper considers a UAV communication system with mobile edge computing(MEC).We minimize the energy consumption of the whole system via jointly optimizing the UAV's trajectory and task assignment as well as CPU's computational speed under the set of resource constrains.To this end,we first derive the energy consumption model of data processing,and then obtain the energy consumption model of fixed-wing UAV's flight.The optimization problem is mathematically formulated.To address the problem,we first obtain the approximate optimization problem by applying the technique of discrete linear state-space approximation,and then transform the non-convex constraints into convex by using linearization.Furthermore,a concave-convex procedure(CCCP) based algorithm is proposed in order to solve the optimization problem approximately.Numerical results show the efficacy of the proposed algorithm.Lingyan Fan Wu Yan Xihan Chen Zhiyong Chen Qingjiang Shi 2019China Communications2019,16,1:8

6Allele-aware chromosome-scale assembly of the allopolyploid genome of hexaploid Ma bamboo(Dendrocalamus latiflorus Munro)显示文摘Dendrocalamus latiflorus Munro is a woody clumping bamboo with rapid shoot growth.Both genetic transformation and clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)gene editing techniques are available for D.latiflorus,enabling reverse genetic approaches.Thus,D.latiflorus has the potential to be a model bamboo species.However,the genome sequence of D.latiflorus has remained unreported due to its polyploidy and large genome size.Here,we sequenced the D.latiflorus genome and assembled it into three allele-aware subgenomes(AABBCC),representingthe largest genome of a major bamboo species.We assembled 70 allelic chromosomes(2,737 Mb)for hexaploid D.latiflorus using both singlemolecule sequencing from the Pacific Biosciences(Pac Bio)Sequel platform and chromosome conformation capture sequencing(Hi-C).Repetitive sequences comprised 52.65%of the D.latiflorus genome.We annotated 135231 protein-coding genes in the genome based on transcriptomes from eight different tissues.Transcriptome sequencing using RNA-Seq and Pac Bio singlemolecule real-time long-read isoform sequencing revealed highly differential alternative splicing(AS)between non-abortive and abortive shoots,suggesting that AS regulates the abortion rate of bamboo shoots.This high-quality hexaploid genome and comprehensive strand-specific transcriptome datasets for this Poaceae family member will pave the way for bamboo research using D.latiflorus as a model species.Yushan Zheng Deming Yang Jundong Rong Liguang Chen Qiang Zhu Tianyou He Lingyan Chen Jing Ye Lili Fan Yubang Gao Hangxiao Zhang Lianfeng Gu 2022Journal of Integrative Plant Biology2022,64,3:6
7L-tyrosine improves neuroendocrine function in a mouse model of chronic stress显示文摘Adult BALB/c mice, individually housed, were stimulated with nine different stressors, arranged randomly, for 4 continuous weeks to generate an animal model of chronic stress. In chronically stressed mice, spontaneous locomotor activity was significantly decreased, escape latency in the Morris water maze test was prolonged, serum levels of total thyrotropin and total triiodothyronine were significantly decreased, and dopamine and norepinephrine content in the pallium, hippocampus and hypothalamus were significantly reduced. All of these changes were suppressed, to varying degrees, by L-tyrosine supplementation. These findings indicate that the neuroendocrine network plays an important role in chronic stress, and that L-tyrosine supplementation has therapeutic effects.Zhihua Wang Jinghua Li Zhiming Wang Lingyan Xue Yi Zhang Yingjie Chen Jun Su Zhongming Li 2012Neural Regeneration Research2012,7,18:5
8Prognostic value of interim ^(18)F-FDG PET/CT in diffuse large B-cell lymphoma显示文摘Objective: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease. The prognostic factor currently used is not accurate enough to predict the outcomes of patients with DLBCL. The prognostic significance of interim PET/CT in DLBCL remains controversial. The aim of this study is to determine the predictive value of interim 18F-FDG PET/CT after first-line treatment in patients with DLBCL. Methods: Thirty-two patients with DLBCL underwent baseline, interim and post-treatment 18F-FDG PET/CT scans. Imaging results were analyzed for the survival of patients via software SPSS 13.0, retrospectively. Results: Thirty-one of the 32 patients were treated with R-CHOP regimen, and interim 18F-FDG PET/CT of 24 patients was performed after 2 cycles of treatment. After a median follow-up period of 16.7 months, the 2-year progression-free survival (PFS) rates were significantly different between the groups above and below SUV max cut-off value of 2.5 (P=0.039). No significant differences were found in the 2-year PFS rates if SUV max cut-off values were set as 2.0 and 3.0, respectively (P=0.360; P=0.113). Conclusions: Interim PET/CT could predict the prognosis of DLBCL patients with the SUV max cut-off value of 2.5, but more clinical data should be concluded to confirm this conclusion.Zhitao Ying Xuejuan Wang Yuqin Song Wen Zheng Xiaopei Wang Yan Xie Ningjing Lin Meifeng Tu Lingyan Ping Weiping Liu Lijuan Deng Chen Zhang Zhi Yang Jun Zhu 2013Chinese Journal of Cancer Research2013,25,1:4
9Prognostic value of pre-and post-transplantation 18F-fluorodeoxyglucose positron emission tomography results in non-Hodgkin lymphoma patients receiving autologous stem cell transplantation显示文摘Objective: High-dose chemotherapy(HDC) followed by autologous stem cell transplantation(ASCT) is the standard of care in the upfront or relapsed/refractory setting in some patients with non-Hodgkin lymphoma(NHL).However,a proportion of patients do not respond to ASCT.^(18)F-fluorodeoxyglucose(FDG) positron emission tomography(PET)/computed tomography(CT) has been widely used for staging,response evaluation,and prognosis prediction.Here,we investigated the prognostic role of PET/CT in NHL patients before and after ASCT.Methods: A retrospective study was conducted at Peking University Cancer Hospital.All NHL patients who underwent ASCT between March 2010 and July 2016 were identified.Patients who had PET/CT scan before and after ASCT were included.Deauville criteria(5-point scale) were used to interpret PET scans.Univariate and multivariate survival analyses were performed using Cox regression.The predictive value of PET scanning was estimated by comparing the area under the receiver operating characteristic(ROC) curve.Results: In total,79 patients were enrolled in this study.In univariate analysis,pre-and post-ASCT PET result was identified as prognostic factors for 3-year progression-free survival(PFS) and overall survival(OS).Patients with negative pre-ASCT PET result demonstrated significantly better PFS(84.2% vs.54.2%) and OS(89.2% vs.63.6%) than patients with positive pre-ASCT PET result.PFS(91.6% vs.25.3%) and OS(96.5% vs.36.8%) were also significantly different between patients with negative and positive post-ASCT PET result.Multivariate analysis also showed a significant association between survival and post-ASCT PET result.ROC analysis revealed that the predictive value of post-ASCT PET result was superior to that of pre-ASCT PET result alone.Combined pre-and post-ASCT PET result is better for predicting outcomes in patients with NHL receiving transplantation.Deauville criteria score >3 was identified as the best cutoff value for post-ASCT PET.Conclusions: Post-ASCT PET result was more important than pre-ASCT PET result in predicting outcomes for NHL patients who underwent ASCT.The prognostic significance can be improved when combining preASCT PET result with post-ASCT PET result.Deauville criteria can be used for interpreting PET scans in this scenario.Zhitao Ying Lan Mi Xuejuan Wang Yuewei Zhang Zhi Yang Yuqin Song Xiaopei Wang WenZheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Chen Zhang Weiping Liu LijuanDeng Jun Zhu 2017Chinese Journal of Cancer Research2017,29,6:3
10Optimization of the Ultrasonic-assisted Extraction Process for Protocatechuic Acid from Emilia sonchifolia DC by Response Surface Methodology显示文摘[Objectives] This study was conducted to optimize the extraction process of protocatechuic acid from Emilia sonchifolia DC. [Methods] The optimal extraction conditions were determined by single factor,response surface analysis and variance analysis,and the content of protocatechuic acid was determined by HPLC. [Results] The protocatechuic acid standard curve equation was: y = 1 435 x + 8 403,R^2= 0. 999 8,indicating a good linear relationship. The optimal extraction conditions were as follows: a temperature at 80 ℃,an extraction time of 1 h,a material-to-liquid ratio at 1:10 and an ultrasonic power of 600 W,and the content of protocatechuic acid extracted was 1. 93 mg/g. The method showed a RSD of 0. 41%,less than 2%,and the detection limit was 0. 0000047261 g/ml.The experimental sample X1 was the low-level 0. 1 mg/ml standard solution,which showed recovery of protocatechuic acid between 100.8% and 105.2%,with a RSD of 0. 013%;and the sample X2 was the high-level 1. 0 mg/ml standard solution,which exhibited recovery between 100. 6% and 102. 2%,with a RSD of 0.076%. Thus,the recovery was high,and the requirements of the performance index were met. [Conclusions] The detection method is stable and reliable and can produce satisfactory results.Wen CHEN Xiangjun WANG Lingyan LI Zhewen ZHAI Xiaoling HUANG Wubing RAO Chenghan ZOU Tengtong LI 2020Agricultural Biotechnology2020,9,3:3

12Syntenic quantitative trait loci and genomic divergence for Sclerotinia resistance and ?owering time in Brassica napus显示文摘Oilseed rape(Brassica napus) is an allotetraploid with two subgenomes descended from a common ancestor. Accordingly, its genome contains syntenic regions with many duplicate genes, some of which may have retained their original functions, whereas others may have diverged. Here, we mapped quantitative trait loci(QTL) for stem rot resistance(SRR), a disease caused by the fungus Sclerotinia sclerotiorum, and flowering time(FT) in a recombinant inbred line population. The population was genotyped using B.napus 60 K single nucleotide polymorphism arrays and phenotyped in six(FT) and nine(SSR) experimental conditions or environments. In total, we detected 30 SRR QTL and 22 FT QTL and show that some of the major QTL associated with these two traits were co-localized,suggesting a genetic linkage between them. Two SRR QTL on chromosome A2 and two on chromosome C2 were shown to be syntenic, suggesting the functional conservation of these regions. We used the syntenic properties of the genomic regions to exclude genes for selection candidates responsible for QTL-associated traits. For example, 152 of the 185 genes could be excluded from a syntenic A2–C2 region. These findings will help to elucidate polyploid genomics in future studies, in addition to providing useful information for B. napus breeding programs.Fengqi Zhang Junyan Huang Minqiang Tang Xiaohui Cheng Yueying Liu Chaobo Tong Jingyin Yu Tehrim Sadia Caihua Dong Lingyan Liu Baojun Tang Jianguo Chen Shengyi Liu 2019Journal of Integrative Plant Biology2019,61,1:3
13Artificial intelligence-assisted automatic and index-based microbial single-cell sorting system for One-Cell-One-Tube显示文摘Identification,sorting,and sequencing of individual cells directly from in situ samples have great potential for in-depth analysis of the structure and function of microbiomes.In this work,based on an artificial intelligence(AI)-assisted object detection model for cell phenotype screening and a cross-interface contact method for single-cell exporting,we developed an automatic and index-based system called EasySort AUTO,where individual microbial cells are sorted and then packaged in a microdroplet and automatically exported in a precisely indexed,“One-Cell-One-Tube”manner.The target cell is automatically identified based on an AI-assisted object detection model and then mobilized via an optical tweezer for sorting.Then,a crossinterface contact microfluidic printing method that we developed enables the automated transfer of cells from the chip to the tube,which leads to coupling with subsequent single-cell culture or sequencing.The efficiency of the system for single-cell printing is>93%.The throughput of the system for single-cell printing is~120 cells/h.Moreover,>80%of single cells of both yeast and Escherichia coli are culturable,suggesting the superior preservation of cell viability during sorting.Finally,AI-assisted object detection supports automated sorting of target cells with high accuracy from mixed yeast samples,which was validated by downstream single-cell proliferation assays.The automation,index maintenance,and vitality preservation of EasySort AUTO suggest its excellent application potential for single-cell sorting.Zhidian Diao Lingyan Kan Yilong Zhao Jingyun Song Chen Wang Yang Liu Fengli Zhang Teng Xu Rongze Chen Xixian Wang Xiaoyan Jing Jian Xu Yuandong Li Bo Ma 2022mLife2022,1,4:2
14The traditional Chinese medicines treat chronic heart failure and their main bioactive constituents and mechanisms显示文摘Chronic heart failure(CHF)is a severe public health problem with increasing morbidity and mortality,any treatment targeting a single session is insufficient to tackle this.CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling,which might be related to oxidative stress,inflammation,endoplasmic reticulum stress,apoptosis,autophagy,mitochondrial function,and angiogenesis.These molecular mechanisms interact with each other through crosstalk.Historically,Chinese medicinal herbs have been widely applied in the treatment of CHF,and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades.Traditional Chinese medicine(TCM)with multiple components can confront the different pathogenesis of CHF through multiple targets.This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials.Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms.This review comprehensively covers the key works on the effects and underlying mechanisms of TCM,herbal ingredients and synergistic effects of constituent compatibility in treating CHF,providing additional ideas to address this threat.Jie Chen Xiaohong Wei Qian Zhang Yuzhuo Wu Guiyang Xia Huan Xia Lingyan Wang Hongcai Shang Sheng Lin 2023Acta Pharmaceutica Sinica B2023,13,5:2
15PEG-asparaginase in BFM-90 regimen improves outcomes in adults with newly diagnosed lymphoblastic lymphoma显示文摘Objective: Although L-asparaginase(L-ASP) is a standard treatment for lymphoblastic lymphoma(LBL),hypersensitivity reactions by some patients limit its application. Polyethylene glycol-conjugated asparaginase(PEGASP) has a lower immunogenicity and is a standard treatment in all pediatric acute lymphoblastic leukemia(ALL).In this study, we investigated the efficacy and toxicity of PEG-ASP instead of L-ASP as used in the BFM-90regimen(PEG-ASP-BFM-90) for adult LBL.Methods: Between June 2012 and July 2015, we treated 30 adult patients with newly diagnosed LBL, using PEGASP-BFM-90 in a prospective, multicenter and single-arm clinical study at 5 participating institutions in China.Results: All the 30 patients, including 19 males and 11 females with a median age of 30(range: 18–62) years,completed 128 times of the PEG-ASP, with the median of 4(range: 2–6) times. Patients did not receive radiotherapy at this time. The overall response rate was 86.7%(26/30), with 50.0%(15/30) complete response and36.7%(11/30) partial response. The 3-year overall survival was 46.0% [95% confidence interval(95% CI),28.2%–64.8%], and the 3-year progression-free survival was 43.0%(95% CI, 25.7%–62.0%). Major adverse events were myelosuppression, reduced fibrinogen, liver dysfunction and digestive tract toxicities. No allergic reaction and no treatment-related mortality or severe complications were recorded.Conclusions: Our clinical data and observed outcomes indicate that 1 dose of PEG-ASP can replace multiple doses of native L-ASP in BFM-90, with predominantly grade 3–4 neutropenia for adult LBL, and no therapyrelated deaths. The effect is similar to previous reports of PEG-ASP-containing regimens for adult ALL. Major advantages include less serious allergic reactions, 2–3 weeks of action duration, and convenience for patients and physicians.Wen Zheng Hanyun Ren Xiaoyan Ke Mei Xue Yongqing Zhang Yan Xie Ningjing Lin Meifeng Tu Weiping Liu Lingyan Ping Zhitao Ying Chen Zhang Lijuan Deng Xiaopei Wang Yuqin Song Jun Zhu 2017Chinese Journal of Cancer Research2017,29,1:2
16Design,fabrication and characterization of the X-ray supermirrors显示文摘The design, fabrication and characterization of the X-ray supermirrors are discussed in this paper. Using the local optimization method of simplex algorithm and the global one of simulated annealing algorithm with different initial multilayer structures, we designed the broad angular band supermirrors with different grazing incidence angle intervals at the energy of 8.0 keV (the Kα line of Cu) and the broad energetic band supermirrors with different energy intervals at fixed grazing incidence angles. The fabricating techniques for depositing non-periodic multilayers are also studied. The W/C and W/Si supermirrors are deposited on silicon substrates and characterized by a high resolution X-ray D1 diffractometer from Bede Company, UK. Choosing the interface roughness and the densities of the materials as independent variables, some measured reflectivity curves are fitted using the Debye-Waller factor with interface roughness. The experimental results show that the optical performances of the fabricated supermirrors are in agreement with the designed ones.WANG Zhanshan WANG Fengli ZHANG Zhong CHENG Xinbin QIN Shuji CHEN Lingyan 2005Science China(Physics,Mechanics & Astronomy)2005,48,5:2

18Motor neuron replacement therapy for amyotrophic lateral sclerosis显示文摘Amyotrophic lateral sclerosis is a motor neuron degenerative disease that is also known as Lou Gehrig’s disease in the United States,Charcot’s disease in France,and motor neuron disease in the UK.The loss of motor neurons causes muscle wasting,paralysis,and eventually death,which is commonly related to respiratory failure,within 3-5 years after onset of the disease.Although there are a limited number of drugs approved for amyotrophic lateral sclerosis,they have had little success at treating the associated symptoms,and they cannot reverse the course of motor neuron degeneration.Thus,there is still a lack of effective treatment for this debilitating neurodegenerative disorder.Stem cell therapy for amyotrophic lateral sclerosis is a very attractive strategy for both basic and clinical researchers,particularly as transplanted stem cells and stem cell-derived neural progenitor/precursor cells can protect endogenous motor neurons and directly replace the lost or dying motor neurons.Stem cell therapies may also be able to re-establish the motor control of voluntary muscles.Here,we review the recent progress in the use of neural stem cells and neural progenitor cells for the treatment of amyotrophic lateral sclerosis.We focus on MN progenitor cells derived from fetal central nervous system tissue,embryonic stem cells,and induced pluripotent stem cells.In our recent studies,we found that transplanted human induced pluripotent stem cell-derived motor neuron progenitors survive well,differentiate into motor neurons,and extend axons into the host white matter,not only in the rostrocaudal direction,but also along motor axon tracts towards the ventral roots in the immunodeficient rat spinal cord.Furthermore,the significant motor axonal extension after neural progenitor cell transplantation in amyotrophic lateral sclerosis models demonstrates that motor neuron replacement therapy could be a promising therapeutic strategy for amyotrophic lateral sclerosis,particularly as a variety of stem cell derivatives,including induced pluripotent stem cells,are being considered for clinical trials for various diseases.Bochao Liu Mo Li Lingyan Zhang Zhiguo Chen Paul Lu 2022Neural Regeneration Research2022,17,8:2
19High-performance modified uni-traveling carrier photodiode integrated on a thin-film lithium niobate platform显示文摘Lithium niobate on insulator(LNOI)has become an intriguing platform for integrated photonics for applications in communications,microwave photonics,and computing.Whereas,integrated devices including modulators,resonators,and lasers with high performance have been recently realized on the LNOI platform,high-speed photodetectors,an essential building block in photonic integrated circuits,have not been demonstrated on LNOI yet.Here,we demonstrate for the first time,heterogeneously integrated modified uni-traveling carrier photodiodes on LNOI with a record-high bandwidth of 80 GHz and a responsivity of 0.6 A/W at a 1550-nm wavelength.The photodiodes are based on an n-down In GaAs/InP epitaxial layer structure that was optimized for high carrier transit time-limited bandwidth.Photodiode integration was achieved using a scalable wafer die bonding approach that is fully compatible with the LNOI platform.XIANGWEN GUO LINBO SHAO LINGYAN HE KEVIN LUKE JESSE MORGAN KEYE SUN JUNYI GAO TA-CHING TZU YANG SHEN DEKANG CHEN BINGTIAN GUO FENGXIN YU QIANHUAN YU MASOUD JAFARI MARKO LONčAR MIAN ZHANG ANDREAS BELING 2022Photonics Research2022,10,6:2
20A large-scale outdoor atmospheric simulation smog chamber for studying atmospheric photochemical processes:Characterization and preliminary application显示文摘Understanding the formation mechanisms of secondary air pollution is very important for the formulation of air pollution control countermeasures in China.Thus,a large-scale outdoor atmospheric simulation smog chamber was constructed at Chinese Research Academy of Environmental Sciences(the CRAES Chamber),which was designed for simulating the atmospheric photochemical processes under the conditions close to the real atmospheric environment.The chamber consisted of a 56-m^(3) fluorinated ethylene propylene(FEP) Teflon film reactor,an electrically-driven stainless steel alloy shield,an auxiliary system,and multiple detection instrumentations.By performing a series of characterization experiments,we obtained basic parameters of the CRAES chamber,such as the mixing ability,the background reactivity,and the wall loss rates of gaseous compounds(propene,NO,NO_(2),ozone) and aerosols(ammonium sulfate).Oxidation experiments were also performed to study the formation of ozone and secondary organic aerosol(SOA),including α-pinene ozonolysis,propene and 1,3,5-trimethylbenzene photooxidation.Temperature and seed effects on the vapor wall loss and SOA yields were obtained in this work:higher temperature and the presence of seed could reduce the vapor wall loss;SOA yield was found to depend inversely on temperature,and the presence of seed could increase SOA yield.The seed was suggested to be used in the chamber to reduce the interaction between the gas phase and chamber walls.The results above showed that the CRAES chamber was reliable and could meet the demands for investigating tropospheric chemistry.Junling Li Hong Li Xuezhong Wang Weigang Wang Maofa Ge Hao Zhang Xin Zhang Kun Li Yan Chen Zhenhai Wu Fahe Chai Fan Meng Yujing Mu Abdelwahid Mellouki Fang Bi Yujie Zhang Lingyan Wu Yongchun Liu 2021Journal of Environmental Sciences2021,33,4:2
