| 1 | Simultaneous oxidation of NO,SO_2 and Hg^0 from flue gas by pulsed corona discharge显示文摘A process capable of simultaneously oxidizing NO,SO2,and Hg0 was proposed,using a high-voltage and short-duration positive pulsed corona discharge.By focusing on NO,SO2,and Hg0 oxidation effciencies,the influences of pulse peak voltage,pulse frequency,initial concentration,electrode number,residence time and water vapor addition were investigated.The results indicate that NO,SO2 and Hg0 oxidation effciencies depend primarily on the radicals(OH,HO2,O) and the active species(O3,H2O2,etc.) produced by the pulsed corona discharge.The NO,SO2 and Hg0 oxidation effciencies could be improved as pulse peak voltage,pulse frequency,electrode number and residence time increased,but they were reduced with increasing initial concentrations.By adding water vapor,the SO2 oxidation effciency was improved remarkably,while the NO oxidation effciency decreased slightly.In our experiments,the simultaneous NO,SO2,and Hg0 oxidation effciencies reached to 40%,98%,and 55% with the initial concentrations 479 mg/m3,1040 mg/m3,and 15.0 μg/m3,respectively. | XU Fei,LUO Zhongyang,CAO Wei,WANG Peng,WEI Bo,GAO Xiang,FANG Mengxiang,CEN Kefa State key Laboratory of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China. | 2009 | Journal of Environmental Sciences2009，21，3： | 22 |
| 2 | Predictions of NOx/N2O emissions from an ultra-supercritical CFB boiler using a 2-D comprehensive CFD combustion model显示文摘NOx and N2O emissions from an ultra-supercritical circulating fluidized bed(CFB)boiler were predicted using a two dimensional(2-D)comprehensive computational fluid dynamics(CFD)combustion model.This model was developed from a three dimensional model for a supercritical CFB boiler previously constructed by our group.Based on an analysis of the NOx and N2O conversion processes in a CFB boiler,the primary formation and destruction reactions were introduced into the 2-D model and coupled.The resulting model was validated using data from the Baima 600 MW supercritical CFB boiler,and then applied to a 660 MW ultra-supercritical CFB boiler.The effects of excess air,the secondary air(SA)to(primary air(PA)plus SA)ratio and the SA injection height on NOx and N2O emissions were investigated.The results show that a higher excess air volume increases both NOx and N2O emissions,while increasing the SA/(PA+SA)ratio somewhat reduces both the NOx and N2O concentrations.On the basis of the results of this work,optimal locations for SA injection ports so as to lower NOx and N2O emissions are recommended. | Jieqiang Ji Leming Cheng Yangjun Wei Junfeng Wang Xinyu Gao Mengxiang Fang Qinhui Wang | 2020 | Particuology2020，18，2： | 4 |
| 3 | Review of dielectric drying of foods and agricultural products显示文摘Dielectric drying methods with microwave(MW)and radio frequency(RF)energy as emerging drying technologies have drawn much attention from both research community and industry over the past decades.When properly applied,MW and RF drying can be energy efficient and of great potential to be used for a wide range of materials.However there are few reviews that cover both MW and RF drying technologies.Such a review is timely considering the ever increasing interest of the food industry in adapting energy efficient new drying technologies.This paper attends to provide a comprehensive review on uses of MW and RF energy in drying of foods and agricultural products.It provides a brief discussion on the fundamental theory of MW and RF heating and gives a general overview of the works of the most active research groups on modeling of drying kinetic,energy control strategy and the influence of MW and RF drying conditions on quality and structural changes of the final products.Finally,it proposes possible solutions to main challenges facing the industrial adaptation of the technologies and makes suggestions on further research directions to improve the dielectric drying. | Yunyang Wang Yuanrui Li Shaojin Wang Li Zhang Mengxiang Gao Juming Tang | 2011 | International Journal of Agricultural and Biological Engineering2011，4，1： | 4 |

| 8 | YWHAH activates the HMGA1/PI3K/AKT/mTOR signaling pathway by positively regulating Fra-1 to affect the proliferation of gastric cancer cells显示文摘Fos-related antigen 1(Fra-1)is a nuclear transcription factor that regulates cell growth,differentiation,and apoptosis.It is involved in the proliferation,invasion,apoptosis and epithelial mesenchymal transformation of malignant tumor cells.Fra-1 is highly expressed in gastric cancer(GC),affects the cycle distribution and apoptosis of GC cells,and participates in GC occurrence and development.However,the detailed mechanism of Fra-1 in GC is unclear,such as the identification of Fra-1-interacting proteins and their role in GC pathogenesis.In this study,we identified tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein eta(YWHAH)as a Fra-1-interacting protein in GC cells using co-immunoprecipitation combined with liquid chromatography-tandem mass spectrometry.Experiments showed that YWHAH positively regulated Fra-1 mRNA and protein expression,and affected GC cell proliferation.Whole proteome analysis showed that Fra-1 affected the activity of the high mobility group AT-hook 1(HMGA1)/phosphatidylinositol-4,5-bisphosphate 3-kinase(PI3K)/protein kinase B(AKT)/mechanistic target of rapamycin(mTOR)signaling pathway in GC cells.Western blotting and flow cytometry confirmed that YWHAH activated HMGA1/PI3K/AKT/mTOR signaling pathway by positively regulating Fra-1 to affect GC cell proliferation.These results will help to discover new molecular targets for the early diagnosis,treatment,and prognosis prediction of GC. | JUNYU HE FENG ZENG XI JIN LIN LIANG MENGXIANG GAO WENTAO LI GUIYUAN LI YANHONG ZHOU | 2023 | Oncology Research2023，31，4： | 0 |
