| 1 | Biochar: A review of its impact on pesticide behavior in soil environments and its potential applications显示文摘Biochar is produced from the pyrolysis of carbon-rich plant- and animal-residues under low oxygen and high temperature conditions and has been increasingly used for its positive role in soil compartmentalization through activities such as carbon sequestration and improving soil quality. Biochar is also considered a unique adsorbent due to its high specific surface area and highly carbonaceous nature. Therefore, soil amendments with small amounts of biochar could result in higher adsorption and, consequently, decrease the bioavailability of contaminants to microbial communities, plants, earthworms, and other organisms in the soil. However, the mechanisms affecting the environmental fate and behavior of organic contaminants, especially pesticides in biochar-amended soil, are not well understood. The purpose of this work is to review the role of biochar in primary processes, such as adsorption–desorption and leaching of pesticides. Biochar has demonstrable effects on the fate and effects of pesticides and has been shown to affect the degradation and bioavailability of pesticides for living organisms. Moreover, some key aspects of agricultural and environmental applications of biochar are highlighted. | Mahdi Safaei Khorram Qian Zhang Dunli Lin Yuan Zheng Hua Fang Yunlong Yu | 2016 | Journal of Environmental Sciences2016，28，6： | 20 |
| 2 | Sisyphus effects in hydrogen electrochemistry on metal silicides enabled by silicene subunit edge显示文摘Nonmetal elements strictly govern the electrochemical performance of molybdenum compounds.Yet,the exact role played by nonmetals during electrocatalysis remains largely obscure.With intermetallic MoSi_2comprising silicene subunits,we present an unprecedented hydrogen evolution reaction(HER)behavior in aqueous alkaline solution.Under continuous operation,the HER activity of MoSi_2shows a more than one order of magnitude improvement in current density from 1.1 to 21.5 mA cm^(à2)at 0.4 V overpotential.Meanwhile,this activation behavior is highly reversible,such that voltage withdrawal leads to catalyst inactivation but another operation causes reactivation.Thus,the system shows dynamics strikingly analogous to the legendary Sisyphus’labor,which drops and recovers in a stepwise manner repeatedly,but never succeeds in reaching the top of the mountain.Isomorphic WSi_2behaves almost the same as MoSi_2,whereas other metal silicides with silicyne subunits,including CrSi_2and TaSi_2,do not exhibit any anomalous behavior.A thin amorphous shell of MoSi_2is observed after reaction,within which the Si remains partially oxidized while the oxidation state of Mo is basically unchanged.First-principles calculations further reveal that the adsorption of hydroxide ions on silicene subunit edges and the subsequent Si vacancy formation in MoSi_2jointly lead to the anomalous HER kinetics of the adjacent Mo active centers.This work demonstrates that the role of nonmetal varies dramatically with the electronic and crystallographic structures of silicides and that silicene structural subunit may serve as a promoter for boosting HER in alkaline media. | Zechao Zhuang Yong Li Jiazhao Huang Zilan Li Kangning Zhao Yunlong Zhao Lin Xu Liang Zhou Lyudmila V.

| 3 | Inhibition of Rac1-dependent forgetting alleviates memory deficits in animal models of Alzheimer's disease显示文摘Accelerated forgetting has been identified as a feature of Alzheimer's disease(AD),but the therapeutic efficacy of the manipulation of biological mechanisms of forgetting has not been assessed in AD animal models.Ras-re-lated C3 botulinum toxin substrate 1(Rac1),a small GTPase,has been shown to regulate active forgetting in Drosophila and mice?Here,we showed that Rac1 activity is aberrantly elevated in the hippocampal tissues of AD patients and AD animal models.Moreover,amyloid-beta 42 could induce Rac1 activation in cultured cells.The elevation of Rac1 activity not only accelerated 6-hour spatial memory decay in 3-month-old APP/PS1 mice,but also significantly contributed to severe memory loss in aged APP/PS1 mice.A similar age-dependent Rac1 activity-based memory loss was also observed in an AD fly model.Moreover,inhibition of Rac1 activity could ameliorate cognitive defects and synaptic plasticity in AD animal models.Finally,two novel compounds,identified through behavioral screening of a randomly selected pool of brain permeable small molecules for their positive effect in rescuing memory loss in both fly and mouse models,were found to be capable of inhibiting Rac1 activity.Thus,multiple lines of evidence corroborate in supporting the idea that inhibition of Rac1 activity is effective for treating AD-related memory loss. | Wenjuan Wu Shuwen Du Wei Shi Yunlong Liu Ying Hu Zuolei Xie Xinsheng Yao Zhenyu Liu Weiwei Ma Lin Xu Chao Ma Yi Zhong | 2019 | Protein & Cell2019，10，10： | 10 |
| 4 | Co-infections of SARS-CoV-2 with multiple common respiratory pathogens in infected patients显示文摘Dear Editor,In late December 2019,an outbreak of severe pneumonia caused by an unknown etiological agent was initially reported in Wuhan,China,and then quickly spread throughout China and even abroad(Zhu et al.,2020).Swift control measures and etiological investigations were conducted by the Chinese government,physicians and researchers,and by using high throughput sequencing and virological testing,the mysterious pneumonia pathogen was shown to be a novel coronavirus(SARS-CoV-2)capable of person-to-person transmission(Zhu et al.,2020).Coronaviruses are a group of non-segmented,enveloped and positive-sense RNA viruses that belong to the subfamily of Coronavirinae in the family of Coronavirdiae and order of Nidovirales. | Dachuan Lin Lei Liu Mingxia Zhang Yunlong Hu Qianting Yang Jiubiao Guo Yongchao Guo Youchao Dai Yuzhong Xu Yi Cai Xinchun Chen Zheng Zhang Kaisong Huang | 2020 | Science China(Life Sciences)2020，63，4： | 6 |

| 6 | Effects of aging process on adsorption–desorption and bioavailability of fomesafen in an agricultural soil amended with rice hull biochar显示文摘Biochar has been introduced as an acceptable soil amendment due to its environmental benefits such as sequestering soil contaminants. However, the aging process in biochar amended soil probably decreases the adsorption capacity of biochar through changing its physico-chemical properties. Adsorption, leaching and bioavailability of fomesafen to corn in a Chinese soil amended by rice hull biochar after 0, 30, 90 and 180 days were investigated.Results showed that the addition of 0.5%–2% fresh biochar significantly increases the adsorption of fomesafen 4–26 times compare to unamended soil due to higher SSA of biochar. Biochar amendment also decreases fomesafen concentration in soil pore water by5%–23% resulting lower risk of the herbicide for cultivated plants. However, the aging process decreased the adsorption capacity of biochar since the adsorption coefficient values which was 1.9–12.4 in 0.5%–2% fresh biochar amended soil, declined to 1.36–4.16, 1.13–2.78 and 0.95–2.31 in 1, 3 and 6-month aged treatments, respectively. Consequently, higher desorption, leaching and bioavailable fraction of fomesafen belonged to 6-month aged treatment. Nevertheless, rice hull biochar was effective for sequestering fomesafen as the adsorption capacity of biochar amended soil after 6 months of aging was still 2.5–5 times higher compared to that of unamended soil. | Mahdi Safaei Khorram Dunli Lin Qian Zhang Yuan Zheng Hua Fang Yunlong Yu | 2017 | Journal of Environmental Sciences2017，29，6： | 5 |
| 7 | Thymosin Alpha-1 Inhibits Complete Freund’s Adjuvant-Induced Pain and Production of Microglia-Mediated Pro-inflammatory Cytokines in Spinal Cord显示文摘Activation of inflammatory responses regulates the transmission of pain pathways through an integrated network in the peripheral and central nervous systems.The immunopotentiator thymosin alpha-1(Tal)has recently been reported to have anti-inflammatory and neuroprotective functions in rodents.However,how Tα1 affects inflammatory pain remains unclear.In the present study,intraperitoneal injection of Tal attenuated complete Freund's adjuvant(CFA)-induced pain hypersensitivity,and decreased the up-regulation of pro-inflammatory cytokines(TNF-α,IL-1β,and IL-6)in inflamed skin and the spinal cord.We found that CFA-induced peripheral inflammation evoked strong microglial activation,but the effect was reversed by Tα1.Notably,Tα1 reversed the CFA-induced up-regulation of vesicular glutamate transporter(VGLUT)and down-regulated the vesicular γ-aminobutyric acid transporter(VGAT)in the spinal cord.Taken together,these results suggest that Tα1 plays a therapeutic role in inflammatory pain and in the modulation of microgliainduced pro-inflammatory cytokine production in addition to mediation of VGLUT and VGAT expression in the spinal cord. | Yunlong Xu Yanjun Jiang Lin Wang Jiahua Huang Junmao Wen Hang Lv Xiaoli Wu Chaofan Wan Chuanxin Yu Wenjie Zhang Jiaying Zhao Yinqi Zhou Yongjun Chen | 2019 | Neuroscience Bulletin2019，35，4： | 4 |
| 8 | Flow cytometry investigation of picoplankton across latitudes and along the circum Antarctic Ocean显示文摘Using a flow cytometer (FCM) onboard the R/V Xuelong during the 24th Chinese Antarctic cruise, picoplankton community structure and biomass in the surface water were examined along the latitude and around the Antarctic Ocean. Salinity and temperature were automatically recorded and total Chl a was determined. Along the cruise, the abundance of Synechococcus, Prochlorococcus, pico-eukaryotes and heterotrophic bacteria ranged in 0.001-1.855 × 10 8 ind./L, 0.000-2.778 × 10 8 ind./L, 0.002-1.060 × 10 8 ind./L and 0.132-27.073 × 10 8 ind./L, respectively. Major oceanic distribution of Synechococcus and Prochlorococcus appeared between latitudes 30 N and 30 S. Prochlorococcus was mainly influenced by water temperature, water mass combination and freshwater inflow. Meanwhile, Synechococcus distribution was significantly associated with landing freshwater inflow. Pico-eukaryotes and heterotrophic bacteria were distributed all over the oceans, but with a relatively low abundance in the high latitudes of the Antarctic Ocean. Principal Component Analysis showed that at same latitude of Atlantic Ocean and Indian Ocean, picoplankton distribution and constitution were totally different, geographical location and different water masses combination would be main reasons. | LIN Ling HE Jianfeng ZHAO Yunlong ZHANG Fang CAI Minghong | 2012 | Acta Oceanologica Sinica2012，31，1： | 3 |
| 9 | Parallel Spectral Clustering Based on MapReduce显示文摘Clustering is one of the most widely used techniques for exploratory data analysis.Spectral clustering algorithm,a popular modern clustering algorithm,has been shown to be more effective in detecting clusters than many traditional algorithms.It has applications ranging from computer vision and information retrieval to social science and biology.With the size of databases soaring,clustering algorithms have scaling computational time and memory use.In this paper,we propose a parallel spectral clustering implementation based on MapReduce.Both the computation and data storage are distributed,which solves the scalability problems for most existing algorithms.We empirically analyze the proposed implementation on both benchmark networks and a real social network dataset of about two million vertices and two billion edges crawled from Sina Weibo.It is shown that the proposed implementation scales well,speeds up the clustering without sacrificing quality,and processes massive datasets efficiently on commodity machine clusters. | Qiwei Zhong Yunlong Lin Junyang Zou Kuangyan Zhu Qiao Wang Lei Hu | 2013 | ZTE Communications2013，11，2： | 3 |

| 11 | Estimating the combined toxicity of flufenacet and imazaquin to sorghum with pore water herbicide concentration显示文摘Combined toxicity of herbicides to non-target crops is usually resulted from their successive application.The present study was conducted to assess the combined toxicity of flufenacet(FLU)and imazaquin(IMA)to sorghum with their concentration in soil pore water.The concentrations that inhibited growth by 50%(IC50)of FLU and IMA individually and their combination estimated from the herbicide concentrations in soil pore water notably differed from those based on the amended concentrations,due to the decline in bioavailability resulting from adsorption of the herbicides onto soil.According to the amended concentrations,the combined effect of FLU and IMA in soil on sorghum growth was identified as additive action.Based on the concentration in soil pore water,however,it was determined to be antagonism,which was identical to that observed in a test using culture solution.The results revealed that pore water herbicide concentration might be an effective tool to assess the combined toxicity of herbicides in soil to rotational crops. | Donghong Wang Qian Zhang Yuan Zheng Dunli Lin Yunlong Yu | 2016 | Journal of Environmental Sciences2016，28，3： | 2 |

| 13 | Control over π-π stacking of heteroheptacene-based nonfullerene acceptors for 16% efficiency polymer solar cells显示文摘Nonfullerene acceptors are being investigated for use in polymer solar cells(PSCs),with their advantages of extending the absorption range,reducing the energy loss and therefore enhancing the power conversion efficiency(PCE).However,to further boost the PCE,mobilities of these nonfullerene acceptors should be improved.For nonfullerene acceptors,the π-π stacking distance between cofacially stacked molecules significantly affects their mobility.Here;we demonstrate a strategy to increase the mobility of heteroheptacene-based nonfullerene acceptors by reducing their n'-7r stacking distances via control over the bulkiness of lateral side chains.Incorporation of 2-butyloctyl substituents into the nonfullerene acceptor(M36)leads to an increased mobility with a reduced π-π stacking distance of 3.45 A.Consequently,M36 affords an enhanced PCE of 16%,which is the highest among all acceptor-donor-acceptor-type nonfullerene acceptors to date.This strategy of control over the bulkiness of side chains on nonfullerene acceptors should aid the development of more efficient PSCs. | Yunlong Ma Dongdong Cai Shuo Wan Pan Yin Pengsong Wang Wenyuan Lin Qingdong Zheng | 2020 | National Science Review2020，7，12： | 2 |

| 18 | Correlates of Sexual Lifestyles Among Older Adults Living With HIV in China: Findings From the Sexual Well-being (SWELL) Study显示文摘Sexual lifestyles are closely related to overall human health and well-being.Few studies have focused on sexual lifestyles among older adults living with HIV(OALHIV),especially in low-and middle-income countries.This study is a part of the sexual well-being among older adults in China(SWELL)study,which is a multicenter cross-sectional study focused on sexual health among older adults aged 50 years and older.Participants were 680 OALHIV(≥50 years old)from the SWELL study conducted from June 2020 to December 2022.Data were collected through one-on-one interviews.We used logistic regression to assess the correlates of sexual activity and sexual satis-faction.Among all participants,37.1%were sexually active.Being older,male,in a steady relationship and employed were associated with being sexually active.The prevalence of sexual satisfaction was 69.8%among sexually active OALHIV.Being homosexual and reporting a better general health status were associated with sexual satisfaction.The OALHIV who have depressive symptoms were less likely to report sexual satisfaction.To support holistic healthy aging among OALHIV,it is important for healthcare providers to be educated about the importance of enquiring about sexual activity,satisfaction and problems and addressing concerns while conveying sex-positive attitudes during clinical reviews,as these are still critical aspects of their health and well-being. | Bingyi Wang Xin Peng Leiwen Fu Xinyi Li Tongxin Shi Bowen Liang Tian Tian Thomas Fitzpatrick Zhen Lu Weijie Zhang JunyeBian Xin Xiao YingWang Yunlong Ao Lin Ouyang YongCai Maohe Yu Guohui Wu Linghua Li Xiaojun Meng Huachun Zou | 2023 | Infectious Microbes & Diseases2023，5，3： | 1 |

| 20 | Reservoir Characteristics of Fine-grained Sedimentary Rocks in Saline Lakes in the Cenozoic Upper Ganchaigou Formation,Southwestern Qaidam Basin,NW China显示文摘Cenozoic fine-grained sedimentary rocks in the southwestern Qaidam Basin,as typical salinized lacustrine sediments,are significantly different from those in other freshwater lakes under the impact of the high salinity in the lake.Many fine-grained sedimentary rock samples were selected from the lower member of Neogene(N_(1))in the Gaskule Oilfield,Qaidam Basin,northwest China,with the aim to analyze and test their petrology,pore structure,and organic geochemical characteristics and determine its genesis and geological significance.Based on previous results,a new genesis of mixed sedimentary rocks is proposed.The Cenozoic lacustrine fine-grained sedimentary rocks in SW Qaidam Basin belong to mixed sedimentary rocks,which can be divided into three types,including carbonate and terrigenous clastic-bearing mudstone,carbonate-bearing to terrigenous clastic mixed sedimentary rocks,and carbonate-terrigenous clastic mixed sedimentary rocks.The geneses of mixing are quite different from that of mixed marine rocks.According to the sedimentary characteristics of the salinized lakes,three new geneses of mixed deposits are proposed:syn-sedimentary mixing,varve interbedded mixing,and biogenic mixing.The reservoir spaces of the Cenozoic lacustrine fine-grained sedimentary rocks in SW Qaidam Basin include residual intergranular pores,intercrystalline pores,microfractures,and minor dissolved pores.The reservoirs have super-low porosity and ultra-low permeability,with a porosity of 1.82%-21.04%,averaging 7.71%,and permeability of(0.0028-254.86)×10^(−3)μm^(2),averaging 2.82×10^(−3)μm^(2).The test results of total organic carbon(TOC)content show that the highest content of organic carbon reached 1.41%,and those of vitrinite reflectance show that Ro ranges from 0.525%-0.824%,with an average of 0.806%.The organic geochemical characteristics show that the fine-grained mixed sedimentary rocks of SW Qaidam Basin have the potential for self-generation and self-storage.As an unconventional reservoir,it has potential industrial value.This is the first study of fine-grained sedimentary rocks in the Qaidam Basin,which offers certain theoretical and practical values. | SHENG Jun LIU Jincheng LI Yunlong ZOU Haiyan LONG Anlin WANG Lin LI Jiyong QI Qingshan YANG Xiaojing LI Yanan | 2022 | Acta Geologica Sinica(English Edition)2022，96，3： | 1 |
