| 1 | Regeneration performance and carbon consumption of semi-coke and activated coke for SO_2 and NO removal显示文摘To decrease the operating cost of flue gas purification technologies based on carbon-based materials, the adsorption and regeneration performance of low-price semi-coke and activated coke were compared for SO2 and NO removal in a simulated flue gas. The functional groups of the two adsorbents before and after regeneration were characterized by a Fourier transform infrared(FTIR) spectrometer, and were quantitatively assessed using temperature programmed desorption(TPD) coupled with FTIR and acid–base titration. The results show that semi-coke had higher adsorption capacity(16.2% for SO2 and 38.6% for NO) than activated coke because of its higher content of basic functional groups and lactones. After regeneration, the adsorption performance of semi-coke decreased because the number of active functional groups decreased and the micropores increased. Semi-coke had better regeneration performance than activated coke. Semi-coke had a larger SO2 recovery of 7.2% and smaller carbon consumption of 12% compared to activated coke. The semi-coke carbon-based adsorbent could be regenerated at lower temperatures to depress the carbon consumption, because the SO2 recovery was only reduced a small amount. | Song Ding Yuran Li Tingyu Zhu Yangyang Guo | 2015 | Journal of Environmental Sciences2015，27，8： | 17 |
| 2 | Adsorption and desorption of SO_2, NO and chlorobenzene on activated carbon显示文摘Activated carbon(AC) is very effective for multi-pollutant removal; however, the complicated components in flue gas can influence each other's adsorption. A series of adsorption experiments for multicomponents, including SO_2, NO, chlorobenzene and H2 O,on AC were performed in a fixed-bed reactor. For single-component adsorption, the adsorption amount for chlorobenzene was larger than for SO_2 and NO on the AC. In the multi-component atmosphere, the adsorption amount decreased by 27.6% for chlorobenzene and decreased by 95.6% for NO, whereas it increased by a factor of two for SO_2,demonstrating that a complex atmosphere is unfavorable for chlorobenzene adsorption and inhibits NO adsorption. In contrast, it is very beneficial for SO_2 adsorption. The temperature-programmed desorption(TPD) results indicated that the binding strength between the gas adsorbates and the AC follows the order of SO_2> chlorobenzene > NO. The adsorption amount is independent of the binding strength. The presence of H2 O enhanced the component effects, while it weakened the binding force between the gas adsorbates and the AC. AC oxygen functional groups were analyzed using TPD and X-ray photoelectron spectroscopy(XPS) measurements. The results reveal the reason why the chlorobenzene adsorption is less affected by the presence of other components. Lactone groups partly transform into carbonyl and quinone groups after chlorobenzene desorption. The chlorobenzene adsorption increases the number of C = O groups, which explains the positive effect of chlorobenzene on SO_2 adsorption and the strong NO adsorption. | Yuran Li Yangyang Guo Tingyu Zhu Song Ding | 2016 | Journal of Environmental Sciences2016，28，5： | 8 |

| 4 | Dual single-atom Ce-Ti/MnO_(2)catalyst enhances low-temperature NH_(3)-SCR performance with high H_(2)O and SO_(2)resistance显示文摘Mn-based catalysts have exhibited promising performance in low-temperature selective catalytic reduction of NOx with NH_(3)(NH_(3)-SCR).However,challenges such as H_(2)O-or SO_(2)-induced poisoning to these catalysts still remain.Herein,we report an efficient strategy to prepare the dual single-atom Ce-Ti/MnO_(2)catalyst via ball-milling and calcination processes to address these issues.Ce-Ti/MnO_(2)showed better catalytic performance with a higher NO conversion and enhanced H_(2)O-and SO_(2)-resistance at a lowtemperature window(100−150°C)than the MnO_(2),single-atom Ce/MnO_(2),and Ti/MnO_(2)catalysts.The in situ infrared Fourier transform spectroscopy analysis confirmed there is no competitive adsorption between NOx and H_(2)O over the Ce-Ti/MnO_(2)catalyst.The calculation results showed that the synergistic interaction of the neighboring Ce-Ti dual atoms as sacrificial sites weakens the ability of the active Mn sites for binding SO_(2)and H_(2)O but enhances their binding to NH_(3).The insight obtained in this work deepens the understanding of catalysis for NH_(3)-SCR.The synthesis strategy developed in this work is easily scaled up to commercialization and applicable to preparing other MnO_(2)-based single-atom catalysts. | Jingjing Song Shaomian Liu Yongjun Ji Wenqing Xu Jian Yu Bing Liu Wenxing Chen Jianling Zhang Lihua Jia Tingyu Zhu Ziyi Zhong Guangwen Xu Fabing Su | 2023 | Nano Research2023，16，1： | 1 |

| 7 | Energy-efficient removal of carbamazepine in solution by electrocoagulation-electrofenton using a novel P-rGO cathode显示文摘In this study,carbamazepine(CBZ)decay in solution has been studied by coupling electro-coagulation with electro-Fenton(EC-EF)with a novel P-rGO/carbon felt(CF)cathode,aiming to accelerate the in-situ generation of·OH,instead of adding Fe2+and H2O2.Firstly,the fabri-cated P-rGO and its derived cathode were characterized by XRD,SEM,AFM,XPS and electro-chemical test(EIS,CV and LSV).Secondly,it was confirmed that the performance in removal efficiency and electric energy consumption(EEC)by EC-EF(kobs=0.124 min^(-1),EEC=43.98 kWh/kg CBZ)was better than EF(kobs=0.069 min^(-1),EEC=61.04 kWh/kg CBZ).Then,P-rGO/CF(kobs=0.248 min^(-1),EEC=29.47 kWh/kg CBZ,CE=61.04%)showed the best performance in EC-EF,among all studied heteroatom-doped graphene/CF.This superior performance may be associated with its largest layer spacing and richest C=C,which can promote the electron transfer rate and conductivity of the cathode.Thus,more H2O2 and·OH could be produced to degrade CBZ,and almost 100%CBZ was removed with kobs being 0.337 min^(-1) and the EEC was only 24.18 kWh/kg CBZ,under the optimal conditions(P-rGO loading was 6.0 mg/cm^(2),the current density was 10.0 mA/cm^(2),the gap between electrode was 2.0 cm).Additionally,no matter the influent is acidic,neutral or alkaline,no additional pH adjustment is required for the effluent of EC-EF.At last,an inconsecutive empirical kinetic model was firstly estab-lished to predict the effect of operating parameters on CBZ removal. | Zhihui Xiao Tingyu Cui Zhenbei Wang Yan Dang Meijie Zheng Yixinfei Lin Zilong Song YipingWang Chao Liu Bingbing Xu Amir Ikhlaq Jolanta Kumirska Ewa Maria Siedlecka Fei Qi | 2022 | Journal of Environmental Sciences2022，34，5： | 0 |
| 8 | Neutralization against SARS-CoV-2 Delta/Omicron variants and B cell response after inactivated vaccination among COVID-19 convalescents显示文摘Emerging SARS-CoV-2 variants have made COVID-19 convalescents susceptible to re-infection and have raised concern about the efficacy of inactivated vaccination in neutralization against emerging variants and antigen-specific B cell response.To this end,a study on a long-term cohort of 208 participants who have recovered from COVID-19 was conducted,and the participants were followed up at 3.3(Visit 1),9.2(Visit 2),and 18.5(Visit 3)months after SARS-CoV-2 infection.They were classified into three groups(no-vaccination(n=54),one-dose(n=62),and two-dose(n=92)groups)on the basis of the administration of inactivated vaccination.The neutralizing antibody(NAb)titers against the wild-type virus continued to decrease in the no-vaccination group,but they rose significantly in the one-dose and two-dose groups,with the highest NAb titers being observed in the two-dose group at Visit 3.The NAb titers against the Delta variant for the no-vaccination,one-dose,and two-dose groups decreased by 3.3,1.9,and 2.3 folds relative to the wild-type virus,respectively,and those against the Omicron variant decreased by 7.0,4.0,and 3.8 folds,respectively.Similarly,the responses of SARS-CoV-2 RBD-specific B cells and memory B cells were boosted by the second vaccine dose.Results showed that the convalescents benefited from the administration of the inactivated vaccine(one or two doses),which enhanced neutralization against highly mutated SARS-CoV-2 variants and memory B cell responses.Two doses of inactivated vaccine among COVID-19 convalescents are therefore recommended for the prevention of the COVID-19 pandemic,and vaccination guidelines and policies need to be updated. | Hao Wang Yu Yuan Bihao Wu Mingzhong Xiao Zhen Wang Tingyue Diao Rui Zeng Li Chen Yanshou Lei Pinpin Long Yi Guo Xuefeng Lai Yuying Wen Wenhui Li Hao Cai Lulu Song Wei Ni Youyun Zhao Kani Ouyang Jingzhi Wang Qi Wang Li Liu Chaolong Wang An Pan Xiaodong Li Rui Gong Tangchun Wu | 2023 | Frontiers of Medicine2023，17，4： | 0 |

| 10 | A heuristic mixed real-time task allocation of virtual utilization in multi-core processor显示文摘Multi-core processor is widely used as the running platform for safety-critical real-time systems such as spacecraft,and various types of real-time tasks are dynamically added at runtime.In order to improve the utilization of multi-core processors and ensure the real-time performance of the system,it is necessary to adopt a reasonable real-time task allocation method,but the existing methods are only for single-core processors or the performance is too low to be applicable.Aiming at the task allocation problem when mixed real-time tasks are dynamically added,we propose a heuristic mixed real-time task allocation algorithm of virtual utilization VU-WF(Virtual Utilization Worst Fit)in multi-core processor.First,a 4-tuple task model is established to describe the fixedpoint task and the sporadic task in a unified manner.Then,a VDS(Virtual Deferral Server)for serving execution requests of fixed-point task is constructed and a schedulability test of the mixed task set is derived.Finally,combined with the analysis of VDS's capacity,VU-WF is proposed,which selects cores in ascending order of virtual utilization for the schedulability test.Experiments show that the overall performance of VU-WF is better than available algorithms,not only has a good schedulable ratio and load balancing but also has the lowest runtime overhead.In a 4-core processor,compared with available algorithms of the same schedulability ratio,the load balancing is improved by 73.9%,and the runtime overhead is reduced by 38.3%.In addition,we also develop a visual multi-core mixed task scheduling simulator RT-MCSS(open source)to facilitate the design and verification of multi-core scheduling for users.As the high performance,VU-WF can be widely used in resource-constrained and safety-critical real-time systems,such as spacecraft,self-driving cars,industrial robots,etc. | Hongbiao Liu Mengfei Yang Tingyu Wang Chenghao Song Shenghui Zhu Xi Chen | 2023 | Journal of Information and Intelligence2023，1，2： | 0 |
| 11 | Photobiomodulation inhibits the expression of chondroitin sulfate proteoglycans after spinal cord injury via the Sox9 pathway显示文摘Both glial cells and glia scar greatly affect the development of spinal cord injury and have become hot spots in research on spinal cord injury treatment.The cellular deposition of dense extracellular matrix proteins such as chondroitin sulfate proteoglycans inside and around the glial scar is known to affect axonal growth and be a major obstacle to autogenous repair.These proteins are thus candidate targets for spinal cord injury therapy.Our previous studies demonstrated that 810 nm photo biomodulation inhibited the formation of chondroitin sulfate proteoglycans after spinal cord injury and greatly improved motor function in model animals.However,the specific mechanism and potential targets involved remain to be clarified.In this study,to investigate the therapeutic effect of photo biomodulation,we established a mouse model of spinal cord injury by T9 clamping and irradiated the injury site at a power density of 50 mW/cm~2 for 50 minutes once a day for 7 consecutive days.We found that photobiomodulation greatly restored motor function in mice and down regulated chondroitin sulfate proteoglycan expression in the injured spinal cord.Bioinformatics analysis revealed that photobiomodulation inhibited the expression of proteoglycan-related genes induced by spinal cord injury,and versican,a type of proteoglycan,was one of the most markedly changed molecules.Immunofluorescence staining showed that after spinal cord injury,versican was present in astrocytes in spinal cord tissue.The expression of versican in primary astrocytes cultured in vitro increased after inflammation induction,whereas photobiomodulation inhibited the expression of ve rsican.Furthermore,we found that the increased levels of p-Smad3,p-P38 and p-Erk in inflammatory astrocytes were reduced after photobiomodulation treatment and after delivery of inhibitors including FR 180204,(E)-SIS3,and SB 202190.This suggests that Sma d 3/Sox9 and MAP K/Sox9 pathways may be involved in the effects of photobiomodulation.In summary,our findings show that photobiomodulation modulates the expression of chondroitin sulfate proteoglycans,and versican is one of the key target molecules of photo biomodulation.MAPK/Sox9 and Smad3/Sox9 pathways may play a role in the effects of photo biomodulation on chondroitin sulfate proteoglycan accumulation after spinal cord injury. | Zhihao Zhang Zhiwen Song Liang Luo Zhijie Zhu Xiaoshuang Zuo Cheng Ju Xuankang Wang Yangguang Ma Tingyu Wu Zhou Yao Jie Zhou Beiyu Chen Tan Ding Zhe Wang Xueyu Hu | 2024 | Neural Regeneration Research2024，19，1： | 0 |
| 12 | Effect of Different Lower Irrigation Limits on Rape Quality显示文摘In this study,two rape varieties,'Zajiaolvbang'and'bilv',were used as experimental materials to investigate the effect of different lower irrigation limits(80%,60%,40%and 20%of field capacity)on quality of pot-grown rape.The results showed that contents of soluble sugar,soluble protein,vitamin C,nitrate and organic acids in rape all increased with the decreasing lower irrigation limit.Rape plants represented the best quality with lower irrigation limit of 60%of field capacity. | Chunyan WU Tingyu SONG Xiaoming ZHANG Xue WANG | 2013 | Agricultural Biotechnology2013，2，6： | 0 |
