| 1 | Influence of fuel moisture, charge size, feeding rate and air ventilation conditions on the emissions of PM, OC, EC, parent PAHs, and their derivatives from residential wood combustion显示文摘Controlled combustion experiments were conducted to investigate the influence of fuel charge size, moisture, air ventilation and feeding rate on the emission factors (EFs) of carbonaceous particulate matter, parent polycyclic aromatic hydrocarbons (pPAHs) and their derivatives from residential wood combustion in a typical brick cooking stove. Measured EFs were found to be independent of fuel charge size, but increased with increasing fuel moisture. Pollution emissions from the normal burning under an adequate air supply condition were the lowest for most pollutants, while more pollutants were emitted when an oxygen deficient atmosphere was formed in the stove chamber during fast burning. The impacts of these factors on the size distribution of emitted particles was also studied. Modified combustion efficiency and the four investigated factors explained 68%, 72%, and 64% of total variations in EFs of PM, organic carbon, and oxygenated PAHs, respectively, but only 36%, 38% and 42% of the total variations in EFs of elemental carbon, pPAHs and nitro-PAHs, respectively. | Guofeng Shen Miao Xue Siye Wei Yuanchen Chen Qiuyue Zhao Bing Li Haisuo Wu Shu Tao | 2013 | Journal of Environmental Sciences2013，25，9： | 6 |
| 2 | Emissions of parent, nitrated, and oxygenated polycyclic aromatic hydrocarbons from indoor corn straw burning in normal and controlled combustion conditions显示文摘Emission factors(EFs) of parent polycyclic aromatic hydrocarbons(pPAHs), nitrated PAHs(nPAHs), and oxygenated PAHs(oPAHs)were measured for indoor corn straw burned in a brick cooking stove under diferent burning conditions. The EFs of total 28 pPAHs,6 nPAHs and 4 oPAHs were(7.9 ± 3.4),(6.5 ± 1.6)×10 3, and(6.1 ± 1.4)×10 1mg/kg, respectively. Fuel charge size had insignificant influence on the pollutant emissions. Measured EFs increased significantly in a fast burning due to the oxygen deficient atmosphere formed in the stove chamber. In both restricted and enhanced air supply conditions, the EFs of pPAHs, nPAHs and oPAHs were significantly higher than those measured in normal burning conditions. Though EFs varied among diferent burning conditions, the composition profiles and calculated isomer ratios were similar, without significant diferences. The results from the stepwise regression model showed that fuel burning rate, air supply amount, and modified combustion efciency were the three most significant influencing factors, explaining 72%–85% of the total variations. | Guofeng Shen Miao Xue Siye Wei Yuanchen Chen Bin Wang Rong Wang Yan Lv Huizhong Shen Wei Li Yanyan Zhang Ye Huang Han Chen Wen Wei Qiuyue Zhao Bing Li Haisuo Wu Shu Tao | 2013 | Journal of Environmental Sciences2013，25，10： | 5 |
| 3 | Substantial transition to clean household energy mix in rural China显示文摘The household energy mix has significant impacts on human health and climate,as it contributes greatly to many health-and climate-relevant air pollutants.Compared to the well-established urban energy statistical system,the rural household energy statistical system is incomplete and is often associated with high biases.Via a nationwide investigation,this study revealed high contributions to energy supply from coal and biomass fuels in the rural household energy sector,while electricity comprised∼20%.Stacking(the use of multiple sources of energy)is significant,and the average number of energy types was 2.8 per household.Compared to 2012,the consumption of biomass and coals in 2017 decreased by 45%and 12%,respectively,while the gas consumption amount increased by 204%.Increased gas and decreased coal consumptions were mainly in cooking,while decreased biomass was in both cooking(41%)and heating(59%).The time-sharing fraction of electricity and gases(E&G)for daily cooking grew,reaching 69%in 2017,but for space heating,traditional solid fuels were still dominant,with the national average shared fraction of E&G being only 20%.The non-uniform spatial distribution and the non-linear increase in the fraction of E&G indicated challenges to achieving universal access to modern cooking energy by 2030,particularly in less-developed rural and mountainous areas.In some non-typical heating zones,the increased share of E&G for heating was significant and largely driven by income growth,but in typical heating zones,the time-sharing fraction was<5%and was not significantly increased,except in areas with policy intervention.The intervention policy not only led to dramatic increases in the clean energy fraction for heating but also accelerated the clean cooking transition.Higher income,higher education,younger age,less energy/stove stacking and smaller family size positively impacted the clean energy transition. | Guofeng Shen Rui Xiong Yanlin Tian Zhihan Luo Bahabaike Jiangtulu Wenjun Meng Wei Du Jing Meng Yuanchen Chen Bing Xue Bin Wang Yonghong Duan Jia Duo Fenggui Fan Lei Huang Tianzhen Ju Fenggui Liu Shunxin Li Xianli Liu Yungui Li Mu Wang Ying Nan Bo Pan Yanfang Pan Lizhi Wang Eddy Zeng Chao Zhan Yilin Chen Huizhong Shen Hefa Cheng Shu Tao | 2022 | National Science Review2022，9，7： | 4 |
| 4 | Air pollution and inhalation exposure to particulate matter of different sizes in rural households using improved stoves in central China显示文摘Household air pollution is considered to be among the top environmental risks in China.To examine the performance of improved stoves for reduction of indoor particulate matter(PM) emission and exposure in rural households, individual inhalation exposure to size-resolved PM was investigated using personal portable samplers carried by residents using wood gasifier stoves or improved coal stoves in a rural county in Central China.Concentrations of PM with different sizes in stationary indoor and outdoor air were also monitored at paired sites. The stationary concentrations of size-resolved PM in indoor air were greater than those in outdoor air, especially finer particles PM0.25. The daily averaged exposure concentrations of PM0.25, PM1.0, PM2.5 and total suspended particle for all the surveyed residents were 74.4 ± 41.1, 159.3 ± 74.3, 176.7 ± 78.1 and 217.9 ± 78.1 μg/m3,respectively. Even using the improved stoves, the individual exposure to indoor PM far exceeded the air quality guideline by WHO at 25 μg/m3. Submicron particles PM1.0 were the dominant PM fraction for personal exposure and indoor and outdoor air. Personal exposure exhibited a closer correlation with indoor PM concentrations than that for outdoor concentrations. Both inhalation exposure and indoor air PM concentrations in the rural households with gasifier firewood stoves were evidently lower than the reported results using traditional firewood stoves. However, local governments in the studied rural areas should exercise caution when widely and hastily promoting gasifier firewood stoves in place of improved coal stoves, due to the higher PM levels in indoor and outdoor air and personal inhaled exposure. | Weijian Liu Guofeng Shen Yuanchen Chen Huizhong Shen Ye Huang Tongchao Li Yilong Wang Xiaofang Fu Shu Tao Wenxin Liu Yibo Huang-Fu Weihao Zhang Chunyu Xue Guangqing Liu Fuyong Wu Minghung Wong | 2018 | Journal of Environmental Sciences2018，30，1： | 4 |
| 5 | Influence of fuel mass load,oxygen supply and burning rate on emission factor and size distribution of carbonaceous particulate matter from indoor corn straw burning显示文摘The uncertainty in emission estimation is strongly associated with the variation in emission factor (EF),which could be influenced by a variety of factors such as fuel properties,stove type,fire management and even methods used in measurements.The impacts of these factors are complicated and often interact with each other.Controlled burning experiments were conducted to investigate the influences of fuel mass load,air supply and burning rate on the emissions and size distributions of carbonaceous particulate matter (PM) from indoor corn straw burning in a cooking stove.The results showed that the EFs of PM (EFPM),organic carbon (EFOC) and elemental carbon (EFEC) were independent of the fuel mass load.The differences among them under different burning rates or air supply amounts were also found to be insignificant (p > 0.05) in the tested circumstances.PM from the indoor corn straw burning was dominated by fine PM with diameter less than 2.1 μm,contributing 86.4%±3.9% of the total.The size distribution of PM was influenced by the burning rate and air supply conditions.On average,EF PM,EF OC and EF EC for corn straw burned in a residential cooking stove were (3.84±1.02),(0.846±0.895) and (0.391±0.350) g/kg,respectively.EF PM,EF OC and EF EC were found to be positively correlated with each other (p < 0.05),but they were not significantly correlated with the EF of co-emitted CO,suggesting that special attention should be paid to the use of CO as a surrogate for other incomplete combustion pollutants. | Guofeng Shen Miao Xue Siye Wei Yuanchen Chen Bin Wang Rong Wang Huizhong Shen Wei Li Yanyan Zhang Ye Huang Han Chen Wen Wei Qiuyue Zhao Bin Li Haisuo Wu Shu Tao | 2013 | Journal of Environmental Sciences2013，25，3： | 3 |
| 6 | Polycyclic aromatic hydrocarbons in ambient air,surface soil and wheat grain near a large steel-smelting manufacturer in northern China显示文摘The total concentrations and component profiles of polycyclic aromatic hydrocarbons(PAHs) in ambient air,surface soil and wheat grain collected from wheat fields near a large steel-smelting manufacturer in Northern China were determined.Based on the specific isomeric ratios of paired species in ambient air,principle component analysis and multivariate linear regression,the main emission source of local PAHs was identified as a mixture of industrial and domestic coal combustion,biomass burning and traffic exhaust.The total organic carbon(TOC) fraction was considerably correlated with the total and individual PAH concentrations in surface soil.The total concentrations of PAHs in wheat grain were relatively low,with dominant low molecular weight constituents,and the compositional profile was more similar to that in ambient air than in topsoil.Combined with more significant results from partial correlation and linear regression models,the contribution from air PAHs to grain PAHs may be greater than that from soil PAHs. | Weijian Liu Yilong Wang Yuanchen Chen Shu Tao Wenxin Liu | 2017 | Journal of Environmental Sciences2017，29，7： | 3 |
| 7 | GridNet-3D: A Novel Real-Time 3D Object Detection Algorithm Based on Point Cloud显示文摘3D object detection based on point cloud has an important application prospect in automatic driving technology. Aiming at the low precision of 3D object detection based on point cloud and the poor real-time performance caused by large numbers of 3D convolutions, a novel end-to-end real-time object detection algorithm named GridNet-3D is proposed. In the work, 2D gridmapping is used to preprocess the original point clouds.Then a novel structure grid encoding layer is adopted to encode point cloud features and is gotten grid feature maps in bird’s eye view which is connected to region proposal network module to generate detections. Despite only using point clouds, the results on the KITTI 3D detection benchmark show that our algorithm has higher detection precision and better real-time performance on the detection of cars, pedestrians and cyclists, which has high practical value. | YUE Yuanchen CAI Yunfei WANG Dongsheng | 2021 | Chinese Journal of Electronics2021，30，5： | 3 |

| 13 | Mesenchymal stromal cells attenuate post-stroke infection by preventing caspase-1-dependent splenic marginal zone B cell death显示文摘Dear Editor,Spontaneous infection is one of the most common complications of acute ischemic stroke(AIS)and leads to increased morbidity and mortality in stroke patients.However,current interventions fail to improve clinical outcomes in these patients.Since stroke-induced immunodeficiency is thought to contribute to the risk of infection,1 we hypothesized that mesenchymal stromal cell(MSC)therapy,which harnesses potent immunomodulatory capacities,could be a potential solution.Here,we show that intravenously administered MSCs preferentially migrate to the marginal zone(MZ)of the spleen,preserve the injured MZ B cells and ameliorate post-stroke infection and mortality in the mouse middle cerebral artery occlusion(MCAO)model of AIS. | Yinong Huang Jiancheng Wang Xiaofan Lai Yuan Qiu Jianye Cai Yuanchen Ma Yilin Liu Wei Qiu Zhengqi Lu Andy Peng Xiang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 1 |

| 15 | Beyond displays: The recent progress of liquid crystals for bio/chemical detections显示文摘Liquid crystals (LCs) are often known as electronic displays and have become ubiquitous in our daily life, apart from that, in the past 10 years, LCs have been investigated as exquisitely sensitive reporters for developing new molecular sensing and detection tools. The unique and primary advantage of this class of intriguing materials is the perturbation of the local ordering LCs at mo-lecular scale by bio/chemical species can be communicated within LC molecules and extended over microns, allowing the observation of the optical signals by microscope or even the naked eye. Therefore, it provides a new platform for developing bio/chemical detection and potentially label-free sensing systems. | DONG YuanChen YANG ZhongQiang | 2013 | Chinese Science Bulletin2013，58，21： | 1 |
| 16 | Has China’s Housing Production Peaked?显示文摘China s real estate has been a key engine of its sustained economic expansion.This paper argues,however,that even before the COVID-19 shock,a decades-long housing boom had given rise to severe price misalignments and regional supply-demand mismatches,making an adjustment both necessary and inevitable.We make use of newly available and updated data sources to analyze supply-demand conditions in the fast-moving Chinese economy.The imbalances are then compared to benchmarks from other economies.We conclude that the real estate sector is quite vulnerable to a sustained aggregate growth shock,such as COVID-19 might pose.In our baseline calibration,using input-output tables and taking account of the very large footprint of housing construction and real estate related sectors,the adjustment to a decline in housing activity can easily trim a cumulative 5-10 percent from the level of output over a period of years. | Kenneth Rogoff Yuanchen Yang | 2021 | China & World Economy2021，29，1： | 1 |
